Description

[Technical field]

[0001] The present disclosure relates to a positive displacement machine, a compressor, a temperature control device, and an electronic device. [Background technology]

[0002] 2. Description of the Related Art Conventionally, compressors that compress gas are known (see, for example, Patent Document 1). The compressor described in Patent Document 1 includes a center frame to which a cylinder liner is fixed, a reciprocating member, two shaft members, two drive motors, a first arm, and a second arm.

[0003] The reciprocating member has a piston portion whose both ends are guided by the cylinder liner, and reciprocates in the direction of the common central axis and oscillates about the common central axis. The reciprocating member has a first arm portion disposed at the center of the piston portion and protruding in the left-right direction perpendicular to the axial direction of the piston portion. The drive motor rotates the two shaft members in opposite directions. The two shaft members are mounted on the center frame so that their rotation axes are coaxial with each other and perpendicular to the common central axis of the upper and lower cylinder liners. Each of the two shaft members has a second arm portion into which the first arm portion is inserted, as well as a main balance weight portion and a sub balance weight portion. The main balance weight portion is provided at an axial position near the second arm portion and offset in a direction opposite to the offset direction of the second arm portion. The sub balance weight portion is offset in the opposite direction to the main balance weight portion with respect to the rotor of the drive motor, in the offset direction of the second arm portion. That is, the sub balance weight portion is offset in the opposite direction to the offset direction of the main balance weight portion.

[0004] In such a compressor, the movement of the center of gravity caused by the reciprocating motion of the reciprocating member is suppressed by the rotation of the two shaft members having the main balance weight portion. In addition, the movement of the center of gravity caused by the swinging motion of the reciprocating member is suppressed by the sub-balance weight portion provided on each of the two shaft members. As a result, the vibration of the compressor described in Patent Document 1 is reduced. In addition, the farther the two secondary balance weight units are disposed from the common central axis, the lighter the secondary balance weight units can be. In order to reduce the weight of the compressor, it is preferable to dispose the secondary balance weight units as far away as possible from the common central axis.

[0005] [Patent Document 1] JP 2017-008918 A Summary of the Invention [Problem to be solved by the invention]

[0006] However, the compressor described in Patent Document 1 has a problem in that as the secondary balance weight portion is moved away from the common central axis, the dimensions of the compressor in the direction along the rotational axis of each shaft member become larger. For this reason, there has been a demand for a configuration that can reduce vibration and noise and enable the compressor to be made smaller. [Means for solving the problem]

[0012] [First embodiment] Hereinafter, a first embodiment of the present disclosure will be described with reference to the drawings. [Electronic device configuration] FIG. 1 is a block diagram showing the configuration of an electronic device 1 according to the present embodiment. An electronic device 1 according to this embodiment includes a temperature control target CT and a temperature control device 2, as shown in FIG. The temperature adjustment target CT constitutes the electronic device 1. The temperature adjustment target CT is, for example, a control device that controls the electronic device 1, a power supply device that supplies power to electronic components of the electronic device 1, and the like.

[0013] [Temperature control device configuration] The temperature control device 2 controls the temperature of the temperature control target CT. Specifically, the temperature control device 2 controls the temperature of the temperature control target CT by circulating a working fluid that changes phase between a liquid phase and a gas phase. The temperature adjustment device 2 includes a compressor 3 , a condensation section 21 , an expansion section 22 , an evaporation section 23 , a plurality of connection pipes 24 , and a cooling fan 25 .

[0014] [Compressor configuration] The compressor 3 compresses the gas phase working fluid. That is, the compressor 3 increases the temperature and pressure of the gas phase working fluid by compressing the gas phase working fluid flowing in from the evaporation section 23. The gas phase working fluid increased in temperature and pressure by the compressor 3 flows into the condensation section 21. The configuration of the compressor 3 will be described in detail later.

[0015] [Condenser section configuration] The condenser 21 is connected to the compressor 3 via a connection pipe 24. The condenser 21 condenses the gas phase working fluid compressed by the compressor 3, i.e., the high-temperature and high-pressure gas phase working fluid, into a liquid phase working fluid. Specifically, the condenser 21 condenses the gas phase working fluid into a high-pressure liquid phase working fluid by exchanging heat between the compressed gas phase working fluid and a cooling gas circulated through the condenser 21 by a cooling fan 25.

[0016] [Configuration of the expansion section] The expansion section 22 is a pressure reducer and is connected to the condensation section 21. The expansion section 22 reduces the pressure of the liquid-phase working fluid condensed by the condensation section 21, changing it into a working fluid having a mixed phase of liquid and gas. That is, the expansion section 22 lowers the temperature of the working fluid. The expansion section 22 discharges the working fluid having a mixed phase of liquid and gas to the evaporation section 23. The expansion section 22 can be configured, for example, by an expansion valve capable of controlling the evaporation temperature of the liquid-phase working fluid, more specifically, an electronic expansion valve, or can be configured by a capillary tube.

[0017] [Evaporation section configuration] The evaporation section 23 is connected to the temperature adjustment target CT so as to be capable of transferring heat thereto. The evaporation section 23 evaporates the liquid-phase working fluid flowing from the expansion section 22 by heat transferred from the temperature adjustment target CT, changes it into a gas-phase working fluid, and discharges the changed gas-phase working fluid to the compressor 3. As a result, the heat of the temperature adjustment target CT is consumed, and the temperature adjustment target CT is cooled.

[0018] [Multiple connection pipe configuration] A plurality of connection pipes 24 connect the compressor 3, the condenser section 21, the expansion section 22 and the evaporator section 23 in a ring shape. The multiple connection pipes 24 include a first connection pipe 241, a second connection pipe 242, a third connection pipe 243, and a fourth connection pipe 244. Each of the connection pipes 241 to 244 is a tubular member through which the working fluid can flow. The first connection pipe 241 connects the compressor 3 and the condenser section 21 together. The second connection pipe 242 connects the condensation section 21 and the expansion section 22 together. The third connection pipe 243 connects the expansion section 22 and the evaporation section 23 together. The fourth connection pipe 244 connects the evaporator 23 and the compressor 3 together. In this way, the temperature adjustment device 2 has a circulation path for the working fluid that flows through the compressor 3, the first connection pipe 241, the condenser section 21, the second connection pipe 242, the expansion section 22, the third connection pipe 243, the evaporation section 23, and the fourth connection pipe 244 in this order, and then flows back into the compressor 3. The circulation path adjusts the temperature of the temperature adjustment target CT.

[0019] [Compressor detailed configuration] FIG. 2 is a cross-sectional view showing the compressor 3. As described above, the compressor 3 compresses the gas-phase working fluid flowing in from the evaporation section 23 and discharges it to the condensation section 21. More specifically, the compressor 3 is a reciprocating compressor that compresses the gas-phase working fluid by reciprocating motion of a first piston portion 522 and a second piston portion 523, which will be described later. In this embodiment, the compressor 3 compresses the gas-phase working fluid. As shown in FIG. 2, the compressor 3 includes a drive unit 4 and a positive displacement machine 5A.

[0020] In the following description, three mutually orthogonal directions are defined as +X direction, +Y direction, and +Z direction. The +X direction is a direction along a first rotation axis Rx1 of the first rotation member 54 described later, and a direction from the first rotation member 54 to the second rotation member 55. That is, the +X direction is a leftward direction in the view of FIG. 2. The +X direction corresponds to the second direction. The +Y direction is a direction along a reciprocating motion direction of the slide member 52 described later, and a direction from the second piston portion 523 to the first piston portion 522 of the first piston portion 522 and the second piston portion 523 of the slide member 52. That is, the +Y direction is an upward direction in the view of FIG. 2. The +Y direction is a direction intersecting the rotation axis, and corresponds to the first direction. The +Z direction is a direction toward the paper surface in the view of FIG. 2. The +Z direction corresponds to the third direction. Furthermore, the direction opposite to the +X direction is the -X direction, the direction opposite to the +Y direction is the -Y direction, and the direction opposite to the +Z direction is the -Z direction. Also, the axis along the +X direction is the X-axis, the axis along the +Y direction is the Y-axis, and the axis along the +Z direction is the Z-axis.

[0021] [Drive system configuration] The driving device 4 rotates the rotating members 54, 55 of the positive displacement machine 5A about a rotation axis along the +X direction. The driving device 4 includes a first driving device 41 and a second driving device . The first driving device 41 is provided in the -X direction with respect to the positive displacement machine 5A. The first driving device 41 has a first rotor 411 that rotates the first rotating member 54 of the positive displacement machine 5A about a first rotation axis Rx1 along the +X direction, and a first driving device main body 412 that rotatably supports the first rotor 411. Although detailed illustration is omitted, the first driving device main body 412 has a first stator that rotates the first rotor 411. The second driving device 42 is provided in the +X direction with respect to the positive displacement machine 5A. The second driving device 42 has a second rotor 421 that rotates the second rotating member 55 of the positive displacement machine 5A around a second rotating axis Rx2 along the +X direction in the opposite direction to the first rotating member 54, and a second driving device main body 422 that rotatably supports the second rotor 421. Although detailed illustration is omitted, the second driving device main body 422 has a second stator that rotates the second rotor 421. An extension line of the first rotation axis Rx1 of each of the first rotor 411 and the first rotating member 54 and an extension line of the second rotation axis Rx2 of each of the second rotor 421 and the second rotating member 55 coincide with each other. In this embodiment, the first driving device 41 and the second driving device 42 are configured by motors. However, each of the driving devices 41, 42 may be configured by a driving device other than a motor.

[0022] [Configuration of volumetric machines] The positive displacement machine 5A is driven by the drive unit 4, compresses the gas-phase working fluid flowing in from the evaporation section 23, and discharges the compressed gas-phase working fluid.

The mechanism chamber S1 has lubricating oil therein. In other words, the housing 51 has lubricating oil sealed in the mechanism chamber S1. In this embodiment, the amount of lubricating oil is about half the volume of the mechanism chamber S1, but is not limited to this and can be changed as appropriate. In addition, a bearing 5133 supported by a first partition portion 513 and a bearing 5153 supported by a second partition portion 515, which will be described later, are provided in the mechanism room S1.

In other words, the connecting member 53 can be said to be a part of the slide member 52. The connecting member 53 moves in the ±Y direction due to rotation of the rotating members 54, 55, and moves the sliding member 52 in the ±Y direction. In other words, the connecting member 53 converts the rotational movement of the rotating members 54, 55 into linear movement of the sliding member 52 in the ±Y direction. The connecting member 53 has a first connecting portion 531 in the -X direction and a second connecting portion 532 in the +X direction. The first connecting portion 531 is inserted into the first bearing portion 543 of the first rotating member 54. The second connecting portion 532 is inserted into the second bearing portion 553 of the second rotating member 55 . When the first connecting portion 531 is inserted into the first bearing portion 543, the second connecting portion 532 is inserted into the second bearing portion 553, and the connecting member 53 is arranged such that the direction from the first connecting portion 531 to the second connecting portion 532 is along the +X direction, the connecting member 53 is arranged along the +X direction. That is, in this case, the connecting member 53 extends along the +X direction, which is the second direction, and is arranged along the X-axis. A first adjustment mechanism 6A is provided on such a connecting member 53. The first adjustment mechanism 6A will be described in detail later.

[0040] [Configuration of the first rotating member] The first rotating member 54 is one of the rotating members of the present disclosure, and is disposed in the -X direction with respect to the connecting member 53. The first rotating member 54 is connected to the first rotor 411 of the first driving device 41 and the first connecting portion 531 of the connecting member 53, and rotates together with the first rotor 411 coaxially with the first rotor 411. That is, the first rotating member 54 is connected to the first connecting portion 531, which is one end of the connecting member 53, and rotates around the first rotation axis Rx1 along the +X direction. In other words, the first rotating member 54 is integrated with the first rotor 411, and rotates together with the first rotor 411 around the first rotation axis Rx1 along the X-axis.

[0041] The first rotating member 54 has a semicircular first balance member 541 , a first attachment portion 542 , a first bearing portion 543 , and a first fitting portion 544 . The first balancing member 541 is a counterweight for reducing vibrations caused by the reciprocating motion of the slide member 52 along the Y-axis. The first balancing member 541 is disposed in the -Y direction with respect to the first rotation axis Rx1 when the slide member 52 slides to the maximum in the +Y direction, i.e., when the slide member 52 slides to the top dead center. The first balancing member 541 is disposed in the +Y direction with respect to the first rotation axis Rx1 when the slide member 52 slides to the maximum in the -Y direction, i.e., when the slide member 52 slides to the bottom dead center. The first mounting portion 542 is a portion to which the first balancing member 541 is attached in the first rotating member 54 and is connected to the connecting member 53. The first mounting portion 542 has a hole portion that penetrates the first rotating member 54 along the X-axis, and a first bearing portion 543 is provided inside the hole portion. The first bearing portion 543 is a spherical bearing. The first connecting portion 531 is inserted into the first bearing portion 543. An end portion of the first rotor 411 in the +X direction is inserted into and fitted into the first fitting portion 544. As a result, the first rotating member 54 and the first rotor 411 rotate integrally.

[0042] [Configuration of the second rotating member] The second rotating member 55 is one of the rotating members of the present disclosure, and is disposed in the +X direction with respect to the connecting member 53. The second rotating member 55 is connected to the second rotor 421 of the second driving device 42 and the second connecting portion 532 of the connecting member 53, and rotates together with the second rotor 421 coaxially with the second rotor 421. That is, the second rotating member 55 is connected to the second connecting portion 532, which is the other end of the connecting member 53, and rotates around the second rotating axis Rx2 along the +X direction in the opposite direction to the rotation direction of the first rotating member 54. In other words, the second rotating member 55 is integrated with the second rotor 421, and rotates together with the second rotor 421 around the second rotating axis Rx2 along the X axis. In this embodiment, the extension line of the first rotating axis Rx1 and the extension line of the second rotating axis Rx2 coincide with each other. Incidentally, the fact that the extension line of the first rotation axis Rx1 and the extension line of the second rotation axis Rx2 coincide with each other also includes the case where the extension lines approximately coincide with each other.

[0043] The second rotating member 55 has a semicircular second balance member 551 , a second attachment portion 552 , a second bearing portion 553 , and a second fitting portion 554 . The second balancing member 551, like the first balancing member 541, is a counterweight for reducing vibrations caused by the reciprocating motion of the slide member 52 along the Y axis. The second balancing member 551 is disposed in the -Y direction with respect to the second rotation axis Rx2 when the slide member 52 slides to the top dead center, and is disposed in the +Y direction with respect to the second rotation axis Rx2 when the slide member 52 slides to the bottom dead center. The second mounting portion 552 is a portion to which the second balance member 551 is attached in the second rotating member 55 and is connected to the connecting member 53. The second mounting portion 552 has a hole portion that penetrates the second rotating member 55 along the X-axis, and a second bearing portion 553 is provided inside the hole portion. The second bearing portion 553 is a spherical bearing. The second connecting portion 532 is inserted into the second bearing portion 553. An end portion of the second rotor 421 in the −X direction is inserted into and fitted into the second fitting portion 554. This allows the second rotating member 55 to rotate integrally with the second rotor 421.

[0044] Although not shown, the slide member 52 and the connecting member 53 are rotated clockwise or counterclockwise around the Y axis as viewed from the +Y direction when they move in the ±Y direction with the rotation of the rotating members 54, 55 which rotate in opposite directions. In more detail, when the slide member 52 and the connecting member 53 located at the bottom dead center are moved in the +Y direction with the rotation of the rotating members 54, 55, the slide member 52 and the connecting member 53 are rotated in one of the clockwise and counterclockwise directions as viewed from the +Y direction until they reach half of their movement range in the +Y direction. In addition, the slide member 52 and the connecting member 53 are rotated in the other of the clockwise and counterclockwise directions as viewed from the +Y direction from the position halfway through their movement range in the +Y direction until they reach the top dead center. Furthermore, when the slide member 52 and the connecting member 53, which are located at the top dead center, are moved in the -Y direction with the rotation of the rotating members 54, 55, the slide member 52 and the connecting member 53 are rotated in the other of the clockwise and counterclockwise directions as viewed from the +Y direction until they reach half of their range of movement in the -Y direction. Then, the slide member 52 and the connecting member 53 are rotated in one of the clockwise and counterclockwise directions as viewed from the +Y direction from the position halfway through their range of movement in the -Y direction until they reach the bottom dead center. In this way, the slide member 52 and the connecting member 53 swing clockwise or counterclockwise as viewed from the +Y direction around the Y axis as they reciprocate along the Y axis.

[0045] [Shift in center of gravity due to swinging movement of slide member and connecting member] By arranging the first balance member and the second balance member as described above, the shift in the center of gravity associated with the reciprocating motion of the slide member and the connecting member along the Y axis is suppressed, thereby making it possible to reduce vibration and noise of the positive displacement machine, and ultimately, the compressor. On the other hand, the movement of the center of gravity caused by the rocking movement of the slide member and the connecting member about the slide axis of the slide member leads to vibration and noise in the positive displacement machine, and in turn, in the compressor.

[0046] Fig. 3 is a view of the compressor P3 having the sub-balance members PSW1 and PSW2 as viewed from the +Y direction. Note that in Fig. 3, the illustration of the housing of the displacement type machine P5 of the compressor P3 is omitted. To address such a problem, the compressor P3 shown in Fig. 3 includes a first sub-balancing member PSW1 and a second sub-balancing member PSW2. More specifically, the compressor P3 includes a driving device 4 and a positive displacement machine P5. The displacement machine P5 includes a housing (not shown), a slide member P52, a connecting member P53, a first rotating member P54, a second rotating member P55, as well as a first sub-balancing member PSW1 and a second sub-balancing member PSW2. The slide member P52 has a similar configuration to the slide member 52, and the connecting member P53 has a similar configuration to the connecting member 53 that is not provided with a first adjustment mechanism 6A described later. The first rotating member P54 has a similar configuration to the first rotating member 54, except that it has a first main balance member P541 instead of the first balance member 541. The second rotating member P55 has a similar configuration to the second rotating member 55, except that it has a second main balance member P551 instead of the second balance member 551.

[0047] In the compressor P3, a first sub-balancing member PSW1 is disposed on the first rotor 411 that rotates the first rotating member P54, on the opposite side to the first main balance member P541 with respect to the first driving device body 412. The first sub-balancing member PSW1 is eccentric in a direction opposite to the eccentric direction of the first main balance member P541 on the first rotor 411. In addition, in the second rotor 421 that rotates the second rotating member P55, a second sub-balancing member PSW2 is disposed on the opposite side of the second main balance member P551 with respect to the second driving device body 422. The second sub-balancing member PSW2 is eccentric in the opposite direction to the eccentric direction of the second main balance member P551 in the second rotor 421.

[0048] In this way, when providing sub-balance members PSW1, PSW2, in order to reduce the shift in the center of gravity associated with the swinging movement of the slide member P52 and the connecting member P53 around the slide axis along the Y axis, each sub-balance member PSW1, PSW2 is positioned so that the following equation 1 holds. In the formula 1, Lm is the distance between the first main balance member P541 and the second main balance member P551, Fm is the X-axis component of the centrifugal force of each of the main balance members P541 and P551, Ls is the distance between the first sub-balance member PSW1 and the second sub-balance member PSW2, Fs is the X-axis component of the centrifugal force of each of the sub-balance members PSW1 and PSW2, and N is the primary rotational component of the moment due to the inertial force caused by the swinging motion of the slide member P52 and the connecting member P53 around the slide axis As. In other words, Lm is the total distance between the first main balance member P541 and the slide axis As and the distance between the slide axis As and the second main balance member P551. Also, Ls is the total distance between the first sub-balance member PSW1 and the slide axis As and the distance between the slide axis As and the second sub-balance member PSW2. Lm×Fm = Ls×Fs+N …(1)

[0049] It can be seen from the above formula 1 that as the distance Ls increases, lighter first sub-balancing member PSW1 and second sub-balancing member PSW2 can be adopted. That is, as the positions of the first sub-balancing member PSW1 and the second sub-balancing member PSW2 are farther away from the slide axis As, lighter first sub-balancing member PSW1 and second sub-balancing member PSW2 can be adopted.

[0050] However, when the first sub-balancing member PSW1 is provided on the first rotor 411 and the second sub-balancing member PSW2 is provided on the second rotor 421, there is a problem in that the dimensions of the displacement machine P5 along each of the rotation axes Rx1, Rx2, and ultimately the dimensions of the compressor P3, become large.

[0051] FIG. 4 is a perspective view showing the first adjustment mechanism 6A provided on the connecting member 53. As shown in FIG. In contrast, the displacement machine 5A according to this embodiment includes a first adjustment mechanism 6A for adjusting the magnitude of the moment generated by the swinging motion of the slide member 52 connected to the connecting member 53 about the slide axis As along the Y axis, as shown in FIG. 4. In the displacement machine 5A, the first sub-balance member PSW1 and the second sub-balance member PSW2 are not provided, and the above formula 1 is established by the first adjustment mechanism 6A. That is, in the displacement machine 5A, the sub-balance members PSW1 and PSW2 are not provided, and the rotational primary component N of the moment caused by the inertial force associated with the swinging motion of the slide member 52 connected to the connecting member 53 about the slide axis As is made equal to the product of the distance Lm between the first balance member 541 and the second balance member 551 and the X-axis component Fm of the centrifugal force of each balance member 541 and 551. This reduces the center of gravity movement associated with the swinging motion of the slide member 52 and the connecting member 53, thereby reducing vibration and noise. The first adjustment mechanism 6A will be described in detail below.

[0052] [Configuration of the first adjustment mechanism] 3, the first adjustment mechanism 6A according to the present embodiment is provided on the connecting member 53 and adjusts the magnitude of the moment generated by the pivoting motion of the slide member 52 to which the connecting member 53 is connected, about a slide axis As along the Y axis. The slide axis As is the pivot axis of the slide member 52 and the connecting member 53. The first adjustment mechanism 6A has a base portion 61 and an adjustment portion 62. The base portion 61 is connected to the shaft portion 521 of the slide member 52. The base portion 61 is integrated with the connecting member 53. That is, the base portion 61 is a portion of the connecting member 53 that is connected to the shaft portion 521. The adjustment portion 62 is a portion that adjusts the magnitude of the moment. When the connecting member 53 is disposed along the X-axis, the adjustment portion 62 extends from the base portion 61 in a +Z direction that is perpendicular to the +Y direction and intersects with the +X direction, and in a -Z direction. The +X direction corresponds to the first direction, the +Z direction corresponds to the third direction, and the -Z direction corresponds to the direction opposite to the third direction. The adjustment portion 62 includes a first portion 63 and a second portion 64.

[0053] The first portion 63 extends in the +Z direction from the base portion 61. The first portion 63 has a first extending portion 631 and a first weight portion 632. The first extending portion 631 is connected to the base portion 61, and extends from the base portion 61 in the +Z direction in a rod shape. First weight portion 632 is disposed at the tip of first extending portion 631. That is, first weight portion 632 is provided at the end portion of first extending portion 631 opposite base portion 61. In this embodiment, first weight portion 632 is formed in a spherical shape, but the shape of first weight portion 632 can be appropriately changed to a prismatic shape, for example. The center of gravity of the first portion 63 is located in the +Z direction with respect to the center of the first portion 63 in the +Z direction. In other words, the center of gravity of the first portion 63 is located on the opposite side to the base portion 61 with respect to the center of the first portion 63 in the extension direction of the first portion 63 from the base portion 61.

[0054] The second portion 64 extends in the −Z direction from the base portion 61. The second portion 64 has a second extending portion 641 and a second weight portion 642. The second extending portion 641 is connected to the base portion 61, and extends from the base portion 61 in the -Z direction in a rod shape. The second weight portion 642 is disposed at the tip of the second extending portion 641. That is, the second weight portion 642 is provided at the end portion of the second extending portion 641 opposite to the base portion 61. In this embodiment, the second weight portion 642 is formed in a spherical shape, but the shape of the second weight portion 642 can be appropriately changed to a prismatic shape or the like. The center of gravity of the second portion 64 is located in the -Z direction with respect to the center of the second portion 64 in the -Z direction. In other words, the center of gravity of the second portion 64 is located on the opposite side to the base portion 61 with respect to the center of the second portion 64 in the extension direction of the second portion 64 from the base portion 61. Thus, the adjustment portion 62 has a pair of extension portions 631, 641 extending in the +Z direction and the -Z direction, respectively, and a pair of weight portions 632, 642 arranged at the tip of each extension portion 631, 641.

[0055] [Cross-sectional shape of the first adjustment mechanism] FIG. 5 is a cross-sectional view of the first adjustment mechanism 6A. 5, the cross-sectional shape of the first adjustment mechanism 6A along an imaginary plane defined by the extension direction of the first portion 63 and the second portion 64 and the Y axis along the sliding direction of the sliding member 52 and the connecting member 53 is a shape that is symmetrical with respect to the sliding axis As of the sliding member 52 and the connecting member 53. In other words, the cross-sectional shape of the adjustment part 62 along the imaginary plane is a shape that is symmetrical with respect to the sliding axis As. As a result, the oscillation of the connecting member 53 provided with the first adjustment mechanism 6A around the slide axis As can be stabilized, and in turn, the primary rotational component N of the moment generated by the oscillation motion of the slide member 52 and the connecting member 53 can be made equal to the product of the distance Lm between the first balance member 541 and the second balance member 551 and the X-axis component Fm of the centrifugal force of each balance member 541, 551. Therefore, the vibration caused by the rocking movement of the slide member 52 and the connecting member 53 can be reduced.

[0056] [Function of the first adjustment mechanism] By adjusting the positions of the first weight portion 632 and the second weight portion 642 with respect to the slide axis As to adjust the outer diameter, weight, and center of gravity position of the connecting member 53, the magnitude of the moment generated by the swinging motion of the slide member 52 connected to the connecting member 53, that is, the magnitude of the moment generated by the swinging motion of the slide member 52 and the connecting member 53, is adjusted. In other words, by adjusting the positions of the first weight portion 632 and the second weight portion 642 with respect to the slide axis As, the magnitude of the first rotation component N is adjusted. As a result, the magnitude of the first rotation component N can be made equal to the product of the distance Lm and the X-axis direction component Fm. Therefore, by using the slide member 52 and the connecting member 53 in which the magnitude of the moment generated by the swinging motion is adjusted by the first adjustment mechanism 6A, the shift of the center of gravity accompanying the swinging motion of the slide member 52 and the connecting member 53 can be reduced, and therefore vibration and noise can be reduced.

[0057] [Effects of the first embodiment] The electronic device 1 according to the present embodiment described above provides the following advantages. The electronic device 1 includes a temperature adjustment device 2 . The temperature adjustment device 2 includes a compressor 3 that compresses a gas-phase working fluid, a condensation section 21, an expansion section 22, and an evaporation section . The condenser section 21 condenses the gas-phase working fluid compressed by the compressor 3 into a liquid-phase working fluid. The expansion section 22 reduces the pressure of the liquid-phase working fluid condensed by the condensation section 21, and changes the liquid-phase working fluid into a mixed-phase working fluid of liquid and gas phases. The evaporator 23 is connected to the temperature adjustment target CT so as to be capable of transferring heat therethrough. The evaporator 23 changes the working fluid flowing from the expansion unit 22 into a gas-phase working fluid by heat transferred from the temperature adjustment target CT, and discharges the changed gas-phase working fluid to the compressor 3. The compressor 3 includes a positive displacement machine 5A and a drive device 4 that rotates a first rotating member 54 and a second rotating member 55. The first piston portion 522 and the second piston portion 523 compress the gas that has flowed into the pressure chambers S2 and S3.

[0058] The positive displacement machine 5A includes a housing 51, a sliding member 52, a connecting member 53, rotating members 54 and 55, and a first adjustment mechanism 6A. The housing 51 has an accommodating section 511 in which a mechanism chamber S1 containing lubricating oil is provided, a cylindrical first guide section 512 in which a first pressure chamber S2 is provided, and a cylindrical second guide section 514 in which a second pressure chamber S3 is provided. The first pressure chamber S2 and the second pressure chamber S3 correspond to pressure chambers. The slide member 52 has a shaft portion 521, a first piston portion 522, and a second piston portion 523, and slides along the +Y direction. The +Y direction corresponds to the first direction. The shaft portion 521 extends along the +Y direction, and a part of the shaft portion 521 is disposed within the mechanism chamber S1. The first piston portion 522 is provided at the end of the shaft portion 521 in the +Y direction, and is disposed within the first guide portion 512. The second piston portion 523 is provided at the end of the shaft portion 521 in the -Y direction, and is disposed within the second guide portion 514.

[0059] The connecting member 53 is disposed in the mechanism compartment S1. The connecting member 53 is connected to the slide member 52. The first rotating member 54 is disposed in the mechanism compartment S1 and is connected to one end of the connecting member 53. The first rotating member 54 is rotated by the first driving device 41 about a first rotation axis Rx1 that is aligned along the +X direction intersecting with the +Y direction. The second rotating member 55 is disposed in the mechanism room S1 and is connected to the other end of the connecting member 53. The second rotating member 55 is rotated by the second driving device 42 about a second rotation axis Rx2 that is along the -X direction intersecting with the +Y direction. The first adjustment mechanism 6A adjusts the magnitude of the moment generated by the swinging motion of the slide member 52 to which the connecting member 53 is connected. That is, the first adjustment mechanism 6A adjusts the magnitude of the moment generated by the swinging motion of the slide member 52 and the connecting member 53 along the +Y direction and around the slide axis As that coincides with the swing axis. The first adjustment mechanism 6A is disposed inside the mechanism chamber S1.

[0060] According to this configuration, the first adjustment mechanism 6A can increase or decrease the primary rotation component of the moment of inertia force accompanying the swinging motion of the slide member 52 and the connecting member 53. Therefore, the primary rotation component can be made equal to the product of the distance between the balance members 541, 551 and the X-axis direction component of the centrifugal force of each balance member 541, 551. This makes it possible to reduce vibration and noise caused by the swinging motion of the slide member 52 and the connecting member 53 accompanying the rotation of the rotating members 54, 55. Furthermore, since the first adjustment mechanism 6A can reduce vibrations caused when the slide member 52 and the connecting member 53 swing, there is no need to provide the above-mentioned first sub-balancing member PSW1 and second sub-balancing member PSW2. This allows the dimension of the positive displacement machine 5A in the +X direction to be reduced, and the positive displacement machine 5A can be made more compact. This allows the compressor 3, temperature control device 2, and electronic device 1 to be configured in a smaller size while reducing vibrations.

[0061] In the positive displacement machine 5A, the first adjustment mechanism 6A is provided on the connecting member 53. The first adjustment mechanism 6A has a base portion 61 connected to the slide member 52, and adjustment portions 62 extending from the base portion 61 in the +Z direction intersecting the +Y direction and in the direction opposite to the +Z direction. The +Z direction corresponds to the third direction. The cross-sectional shape of the adjustment part 62 along an imaginary plane including the slide axis As of the slide member 52 and the +Z direction is a shape that is symmetrical with respect to the slide axis As. In other words, the cross-sectional shape of the adjustment part 62 along the YZ plane is symmetrical with respect to the slide axis As. According to this configuration, the center of gravity of the first adjustment mechanism 6A can be positioned on the slide axis As, so that the swinging motion of the connecting member 53 to which the first adjustment mechanism 6A is provided can be stabilized. Therefore, vibrations caused by the swinging motion of the slide member 52 and the connecting member 53 can be reduced.

[0062] In the positive displacement machine 5A, the adjustment unit 62 has a first portion 63 extending in the +Z direction from the base portion 61, and a second portion 64 extending in the -Z direction from the base portion 61. The center of gravity of the first portion 63 is located in the +Z direction with respect to the center position of the first portion 63 in the +Z direction. The center of gravity of the second portion 64 is located in the -Z direction with respect to the center position of the second portion 64 in the -Z direction.

[0063] According to this configuration, since the adjustment portion 62 has the first portion 63 and the second portion 64, it is easy to configure the cross-sectional shape of the adjustment portion 62 to be symmetrical with respect to the slide axis As. In addition, since the respective centers of gravity of the first portion 63 and the second portion 64 are disposed at the above positions, the primary rotation component can be made larger than when the center of gravity of at least one of the first portion 63 and the second portion 64 is disposed at a position closer to the base portion than the center position of the one portion. Therefore, the primary rotation component can be made easier to be equal to the above product, and vibrations accompanying the swinging motion of the sliding member 52 and the connecting member 53 can be reduced.

[0064] In the positive displacement machine 5A, the +Z direction intersects with the +X direction. The adjustment unit 62 has a pair of extensions 631, 641 and a pair of weights 632, 642. The pair of extensions 631, 641 extend in the +Z direction and the -Z direction, respectively. The pair of weights 632, 642 are disposed at the respective tips of the pair of extensions 631, 641. According to this configuration, the +Z direction is a direction that intersects with the slide axis As and intersects with the direction from the slide axis As toward the connection portion between the connecting member 53 and the first rotating member 54. The -Z direction is a direction that intersects with the slide axis As and intersects with the direction from the slide axis As toward the connection portion between the connecting member 53 and the second rotating member 55. Therefore, the pair of extending portions 631, 641 do not interfere with the connection between the connecting member 53 and the first rotating member 54 and the second rotating member 55. In addition, by adjusting the positions and weights of the weights 632, 642 provided at the tips of the extending portions 631, 641, the primary rotation component can be easily adjusted. Furthermore, since the lubricating oil in the mechanism compartment S1 can be stirred by the adjustment unit 62, the positive displacement machine 5A can be operated smoothly.

[0065] [Second embodiment] Next, a second embodiment of the present disclosure will be described. The electronic device according to this embodiment has a similar configuration to the electronic device 1 according to the first embodiment, but the configuration of the adjustment mechanism of the volumetric machine is different. In the following description, the same reference numerals are used for parts that are the same or substantially the same as parts already described, and the description thereof will be omitted.

[0066] [Configuration of electronic devices, temperature control devices, compressors and positive displacement machines] FIG. 6 is a perspective view showing a connecting member 53 and a first adjustment mechanism 6B included in the electronic device according to this embodiment. The electronic device according to this embodiment has the same configuration and function as the electronic device 1 according to the first embodiment, except that it has a first adjustment mechanism 6B shown in Fig. 6 instead of the first adjustment mechanism 6A. That is, the temperature adjustment mechanism, compressor, and positive displacement machine according to this embodiment have the same configuration and function as the temperature adjustment device 2, compressor 3, and positive displacement machine 5A according to the first embodiment, except that it has a first adjustment mechanism 6B instead of the first adjustment mechanism 6A.

[0067] [Configuration of the first adjustment mechanism] The first adjustment mechanism 6B adjusts the magnitude of the moment generated by the swinging motion of the slide member 52 to which the connecting member 53 is connected. More specifically, the first adjustment mechanism 6B adjusts the magnitude of the moment generated by the swinging motion of the slide member 52 and the connecting member 53 about a swing axis along the Y-axis. The first adjustment mechanism 6B is provided on the connecting member 53, and swings integrally with the connecting member 53 and the slide member 52 to which the connecting member 53 is connected. That is, the first adjustment mechanism 6B is disposed in the mechanism chamber S1. The first adjustment mechanism 6B has a base portion 61 and an adjustment portion 65. The adjustment portion 65 is a portion that adjusts the magnitude of the moment. The adjustment portion 65 has a first portion 66 and a second portion 67.

[0068] The first portion 66 extends in the +Z direction from the base portion 61. That is, the first portion 66 extends from the base portion 61 in a third direction perpendicular to both the slide axis As and the direction from the first connecting portion 531 to the second connecting portion 532. The first portion 66 has a first arc portion 661 . The first arc portion 661 is formed in an arc shape centered on the slide axis As when viewed along the slide axis As. The first arc portion 661 has first upright portions 662 that stand up in the +Y direction and the -Y direction from the outer edge portion of the arc. Therefore, the center of gravity of the first portion 66 is located in the +Z direction with respect to the center position of the first portion 66 in the third direction.

[0069] The second portion 67 extends in the −Z direction from the base portion 61. That is, the second portion 67 extends in a direction opposite to the third direction in which the first portion 66 extends from the base portion 61. The second portion 67 has a second arc portion 671 . The second arc portion 671 is disposed on the opposite side of the slide axis As to the first arc portion 661, and is formed in an arc shape centered on the slide axis As when viewed along the slide axis As. The second arc portion 671 has second upright portions 672 that stand up from the outer edge of the arc in the +Y direction and the -Y direction, respectively. Therefore, the center of gravity of the second portion 67 is located in the direction opposite to the third direction with respect to the center position of the second portion 67 in the direction opposite to the third direction.

[0070] [Cross-sectional shape of the first adjustment mechanism] FIG. 7 is a cross-sectional view of the first adjustment mechanism 6B. 7, the cross-sectional shape of the first adjustment mechanism 6B along an imaginary plane defined by the extension direction of the first portion 66 and the second portion 67 and the Y axis along the sliding direction of the sliding member 52 and the connecting member 53 is a shape that is symmetrical with respect to the sliding axis As. In other words, the cross-sectional shape of the adjustment part 65 along an imaginary plane including the sliding axis As of the sliding member 52 and the extension direction of the first portion 66 and the second portion 67 is a shape that is symmetrical with respect to the sliding axis As. Therefore, similarly to the first adjustment mechanism 6A according to the first embodiment, the swinging of the connecting member 53 provided with the first adjustment mechanism 6B around the slide axis As can be stabilized. Furthermore, the first adjustment mechanism 6B can increase or decrease the moment of inertia force accompanying the swinging motion of the slide member 52 connected to the connecting member 53, and thus can increase or decrease the primary rotational component of the moment of inertia force accompanying the swinging motion of the slide member 52 and the connecting member 53. Therefore, the primary rotational component can be made equal to the above product. This can reduce vibration and noise caused by the swinging motion of the slide member 52 and the connecting member 53 accompanying the rotation of the respective rotating members 54, 55.

[0071] [Function of the first adjustment mechanism] By adjusting the outer diameter of the first portion 66 and the second portion 67 to adjust the outer diameter, weight, and center of gravity position of the connecting member 53, the magnitude of the moment generated by the swinging motion of the slide member 52 connected to the connecting member 53, and therefore the magnitude of the moment generated by the swinging motion of the slide member 52 and the connecting member 53, are adjusted. That is, by adjusting the outer diameter of the first portion 66 and the second portion 67, the magnitude of the first rotation component N is adjusted. As a result, the magnitude of the first rotation component N can be made equal to the product of the distance Lm and the X-axis direction component Fm. Therefore, by using the slide member 52 and the connecting member 53 in which the magnitude of the moment generated by the swinging motion is adjusted by the first adjustment mechanism 6B, the shift of the center of gravity accompanying the swinging motion of the slide member 52 and the connecting member 53 can be reduced, and therefore vibration and noise can be reduced.

[0072] [Effects of the second embodiment] The electronic device according to the present embodiment described above provides the same effects as the electronic device 1 according to the first embodiment, and also provides the following effects. In the positive displacement machine of this embodiment, the adjustment section 65 has a first arc portion 661 centered on the slide axis As, and a second arc portion 671 centered on the slide axis As and arranged on the opposite side of the first arc portion 661 from the slide axis As. According to such a configuration, it is possible to easily align the center of gravity of the entire connecting member 53 with the slide axis As. In addition, it is possible to stabilize the swinging motion of the connecting member 53, and therefore the swinging motion of the slide member 52 and the connecting member 53, while increasing the moment of the connecting member 53.

[0073] [Third embodiment] Next, a third embodiment of the present disclosure will be described. The electronic device according to this embodiment has a similar configuration to the electronic device 1 according to the first embodiment, but the configuration of the adjustment mechanism of the volumetric machine is different. In the following description, the same reference numerals are used for parts that are the same or substantially the same as parts already described, and the description thereof will be omitted.

[0074] [Configuration of electronic devices, temperature control devices, compressors and positive displacement machines] Fig. 8 is a perspective view showing a connecting member 53 and a first adjustment mechanism 6C included in the electronic device according to this embodiment. Specifically, Fig. 8 is a perspective view showing a connecting member 53 and a first adjustment mechanism 6C arranged such that the direction from the first connecting portion 531 to the second connecting portion 532 is along the +X direction. The electronic device according to this embodiment has a first adjustment mechanism 6C shown in Fig. 8 instead of the first adjustment mechanism 6A according to the first embodiment, but has the same configuration and function as the electronic device 1 according to the first embodiment. That is, the temperature adjustment mechanism, compressor, and positive displacement machine according to this embodiment have the same configuration and function as the temperature adjustment device 2, compressor 3, and positive displacement machine 5A according to the first embodiment, but has the first adjustment mechanism 6C instead of the first adjustment mechanism 6A.

[0075] [Configuration of the first adjustment mechanism] The first adjustment mechanism 6C adjusts the magnitude of the moment generated by the swinging motion of the slide member 52 to which the connecting member 53 is connected. That is, the first adjustment mechanism 6C adjusts the magnitude of the moment generated by the swinging motion of the slide member 52 and the connecting member 53 about a swing axis along the Y axis. The first adjustment mechanism 6C is provided on the connecting member 53, and swings integrally with the connecting member 53 and the slide member 52 connected to the connecting member 53. That is, the first adjustment mechanism 6C is disposed in the mechanism chamber S1. The first adjustment mechanism 6C has a base portion 61 and an adjustment portion 68. The adjustment portion 68 is a portion that adjusts the magnitude of the moment. The adjustment portion 68 has a first portion 69 and a second portion .

[0076] The first portion 69 extends from the first connecting portion 531 in the +D1 direction from the slide axis As toward the connection portion between the connecting member 53 and the first rotating member 54. The +D1 direction is also the direction from the second connecting portion 532 toward the first connecting portion 531, and corresponds to the third direction in this embodiment. The first portion 69 has a first extending portion 691 and a first weight portion 692. The first extending portion 691 is a portion that extends in the +D1 direction in the first portion 69. The first extending portion 691 extends from the first connecting portion 531 in the +D1 direction. First weight portion 692 is disposed at the tip of first extending portion 691 in the +D1 direction. That is, first weight portion 692 is disposed at the end of first extending portion 691 opposite base portion 61. In this embodiment, first weight portion 692 is formed in a spherical shape, but the shape of first weight portion 692 can be changed as appropriate. The center of gravity of such first portion 69 is located in the +D1 direction with respect to the central position of first portion 69 in the +D1 direction. Furthermore, the center of gravity between base portion 61 and first weight portion 692 in the +D1 direction is located on the first weight portion 692 side with respect to the central position between base portion 61 and first weight portion 692 in the +D1 direction.

[0077] The second portion 70 extends from the second connecting portion 532 in the -D1 direction, which is the opposite direction from the slide axis As to the +D1 direction. The second portion 70 has a second extending portion 701 and a second weight portion 702. The -D1 direction is the direction from the slide axis As toward the connection portion between the connecting member 53 and the second rotating member 55, and is also the direction from the first connecting portion 531 toward the second connecting portion 532. Furthermore, the -D1 direction corresponds to the opposite direction to the third direction in this embodiment. The second extending portion 701 is a portion that extends in the -D1 direction in the second portion 70. The second extending portion 701 extends from the second connecting portion 532 in the -D1 direction. Second weight portion 702 is disposed at the tip of second extending portion 701 in the -D1 direction. That is, second weight portion 702 is disposed at the end of second extending portion 701 opposite base portion 61. In this embodiment, second weight portion 702 is formed in a spherical shape, but the shape of second weight portion 702 can be changed as appropriate. The center of gravity of the second portion 70 is located in the -D1 direction with respect to the central position of the second portion 70 in the -D1 direction. Furthermore, the center of gravity between the base portion 61 and the second weight portion 702 in the -D1 direction is located on the second weight portion 702 side with respect to the central position between the base portion 61 and the second weight portion 702 in the -D1 direction. Thus, adjustment portion 68 has a pair of extension portions 691, 701 extending in the +D1 direction and the -D1 direction, respectively, and a pair of weights 692, 702 disposed at the respective tips of the pair of extension portions 691, 701.

[0078] [Cross-sectional shape of the first adjustment mechanism] FIG. 9 is a diagram showing a cross section of the first adjustment mechanism 6C along an imaginary plane defined by the +D1 direction and the Y axis. 9, the cross-sectional shape of the first adjustment mechanism 6C along an imaginary plane defined by the extension direction of the first portion 69 and the second portion 70 and the Y axis along the sliding direction of the sliding member 52 and the connecting member 53 is symmetrical with respect to the sliding axis As. In other words, the cross-sectional shape of the adjustment part 68 along the imaginary plane is symmetrical with respect to the sliding axis As. Therefore, similarly to the first adjustment mechanism 6A according to the first embodiment and the first adjustment mechanism 6B according to the second embodiment, it is possible to stabilize the swinging movement of the connecting member 53 provided with the first adjustment mechanism 6C about the slide axis As, and in turn, it is possible to increase or decrease the primary rotational component of the moment of inertia force accompanying the swinging movement of the slide member 52 and the connecting member 53. Therefore, it is possible to make the primary rotational component equal to the above product. This makes it possible to reduce vibration and noise caused by the swinging movement of the slide member 52 and the connecting member 53 accompanying the rotation of the respective rotating members 54, 55.

[0079] [Function of the first adjustment mechanism] By adjusting the positions of the first weight portion 692 and the second weight portion 702 with respect to the slide axis As to adjust the outer diameter, weight, and center of gravity position of the connecting member 53, the magnitude of the moment generated by the swinging motion of the slide member 52 connected to the connecting member 53, that is, the magnitude of the moment generated by the swinging motion of the slide member 52 and the connecting member 53, is adjusted. In other words, by adjusting the positions of the first weight portion 692 and the second weight portion 702 with respect to the slide axis As, the magnitude of the first rotation component N is adjusted. As a result, the magnitude of the first rotation component N can be made equal to the product of the distance Lm and the X-axis direction component Fm. Therefore, by using the slide member 52 and the connecting member 53 in which the magnitude of the moment generated by the swinging motion is adjusted by the first adjustment mechanism 6C, the shift of the center of gravity accompanying the swinging motion of the slide member 52 and the connecting member 53 can be reduced, and therefore vibration and noise can be reduced.

[0080] [Effects of the third embodiment] The electronic device according to the present embodiment described above provides the same effects as the electronic device 1 according to the first embodiment, and also provides the following effects. In the displacement machine according to this embodiment, the adjustment unit 68 has a pair of extensions 691, 701 and a pair of weights 692, 702. Of the pair of extensions 691, 701, the first extension 691 extends from the first connecting portion 531 in the +D1 direction, and the second extension 701 extends from the second connecting portion 532 in the -D1 direction. Of the pair of weights 692, 702, the first weight 692 is disposed at the tip of the first extension 691, and the second weight 702 is disposed at the tip of the second extension 701. The +D1 direction is a third direction from the slide axis As toward the connection portion between the connecting member 53 and the first rotating member 54. The -D1 direction is a direction from the slide axis As toward the connection portion between the connecting member 53 and the second rotating member 55, and is the opposite direction to the third direction.

[0081] With this configuration, the magnitude of the moment can be easily adjusted by adjusting the position and weight of the first weight portion 692 provided at the tip of the first extension portion 691 and the position and weight of the second weight portion 702 provided at the tip of the second extension portion 701. In addition, the dimensions of the first adjustment mechanism 6C in the directions perpendicular to the X-axis and Y-axis can be reduced, which makes it possible to reduce the volume of the mechanism chamber S1 in which the first adjustment mechanism 6C and the connecting member 53 are disposed, thereby enabling the volumetric machine to be made more compact.

[0082] [Fourth embodiment] Next, a fourth embodiment of the present disclosure will be described. The electronic device according to this embodiment has a similar configuration to the electronic device 1 according to the first embodiment, but the configuration and arrangement of the adjustment mechanism of the volumetric machine are different. In the following description, the same reference numerals are used for parts that are the same or substantially the same as parts already described, and the description thereof will be omitted.

[0083] [Configuration of electronic devices, temperature control devices and compressors] 10 is a side view of a positive displacement machine 5D included in the electronic device according to this embodiment, as viewed from the -Z direction. Note that in FIG. 10, the housing 51 is not shown. The electronic device according to this embodiment has the same configuration and functions as the electronic device 1 according to the first embodiment, except that it has a positive displacement machine 5D shown in Fig. 10 instead of the positive displacement machine 5A. That is, the temperature adjustment mechanism and compressor according to this embodiment have the same configuration and functions as the temperature adjustment device 2 and compressor 3 according to the first embodiment, except that it has a positive displacement machine 5D instead of the positive displacement machine 5A.

[0084] [Configuration of volumetric machines] The positive displacement machine 5D according to this embodiment constitutes a compressor together with the drive device 4, similarly to the positive displacement machine 5A according to the first embodiment. The positive displacement machine 5D has the same configuration and function as the positive displacement machine 5A according to the first embodiment, except that it is provided with a slide member 52D and a first adjustment mechanism 6D instead of the slide member 52 and the first adjustment mechanism 6A. That is, the positive displacement machine 5D is provided with the slide member 52D, the connecting member 53, the first rotating member 54, the second rotating member 55, and the first adjustment mechanism 6D, as well as a housing 51 not shown in FIG. 10. The connecting member 53 of the displacement machine 5D according to this embodiment is not provided with the first adjustment mechanisms 6A, 6B, and 6C. However, this is not limited thereto, and the displacement machine 5D may be provided with a connecting member 53 provided with one of the first adjustment mechanisms 6A, 6B, and 6C.

[0085] [Configuration of slide parts] The slide member 52D is connected to the connecting member 53, similar to the slide member 52 according to the first embodiment. The slide member 52D slides in the +Y direction together with the connecting member 53 to change the volume of the first compression chamber S21 of the first pressure chamber S2 and the second compression chamber S31 of the second pressure chamber S3, thereby compressing the gas in the first pressure chamber S2 and the second pressure chamber S3. The slide member 52D has the same configuration and function as the slide member 52 according to the first embodiment, except that it has a first piston portion 524 and a second piston portion 525 instead of the first piston portion 522 and the second piston portion 523. That is, the slide member 52D has a shaft portion 521 a part of which is disposed within the mechanism chamber S1, a first piston portion 524 disposed within the first pressure chamber S2, and a second piston portion 525 disposed within the second pressure chamber S3, and reciprocates along the Y axis.

[0086] [Configuration of the first piston section] The first piston portion 524 is provided at the end of the shaft portion 521 in the +Y direction, and is disposed in the first pressure chamber S2 inside the first guide portion 512. The first piston portion 524 has a piston diameter larger than the piston diameter of the first piston portion 522 according to the first embodiment, and other than that, has the same configuration and function as the first piston portion 522. For example, the piston diameter of the first piston portion 524 is approximately equal to the dimension of the connecting member 53 excluding the first connecting portion 531 and the second connecting portion 532 in the direction from the slide axis As toward the first connecting portion 531.

[0087] [Configuration of the second piston section] The second piston portion 525 is provided at the end of the shaft portion 521 in the −Y direction, and is disposed in the second pressure chamber S3 in the second guide portion 514. The second piston portion 525 has a piston diameter larger than the piston diameter of the second piston portion 523 according to the first embodiment, and other than that, has the same configuration and function as the second piston portion 523. For example, the piston diameter of the second piston portion 525 is approximately the same as the piston diameter of the first piston portion 524.

[0088] [Configuration of the first adjustment mechanism] The first adjustment mechanism 6D adjusts the magnitude of the moment generated by the rocking motion of the slide member 52D to which the connecting member 53 is connected, that is, the magnitude of the moment generated by the rocking motion of the slide member 52D and the connecting member 53 about the slide axis As along the Y axis, similar to the first adjustment mechanism 6A. The first adjustment mechanism 6D has a first adjustment part 71 provided in the first piston part 524 and a second adjustment part 72 provided in the second piston part 525. In other words, the first adjustment mechanism 6D has the first adjustment part 71 arranged in the first pressure chamber S2 and the second adjustment part 72 arranged in the second pressure chamber S3. Therefore, the first adjustment mechanism 6D is arranged in the pressure chambers S2 and S3.

[0089] [Configuration of the first adjustment unit and the second adjustment unit] Each of the first adjustment section 71 and the second adjustment section 72 is a section that adjusts the magnitude of the moment. First adjustment portion 71 extends from first piston portion 524 along the +Y direction which is the extension direction of shaft portion 521. More specifically, first adjustment portion 71 is formed in a cylindrical shape protruding from the outer edge of first piston portion 524 in the -Y direction towards connecting member 53. For this reason, the weight of first piston portion 524 is greater than the weight of first piston portion 522. Second adjustment portion 72 extends from second piston portion 525 along the +Y direction which is the extension direction of shaft portion 521. More specifically, second adjustment portion 72 is formed in a cylindrical shape protruding from the outer edge of second piston portion 525 in the +Y direction towards connecting member 53. For this reason, the weight of second piston portion 525 is greater than the weight of second piston portion 523.

[0090] In this way, the first adjustment section 71 is provided on the first piston section 524, and the second adjustment section 72 is provided on the second piston section 525, so that the weight of the slide member 52D is greater than the weight of the slide member 52 according to the first embodiment. In addition, the piston diameter of the first piston section 524 is greater than the piston diameter of the first piston section 522, and the piston diameter of the second piston section 525 is greater than the piston diameter of the second piston section 523, so that the moment of inertia caused by the swinging motion of the slide member 52D about the slide axis As is greater than the moment of inertia caused by the swinging motion of the slide member 52 about the slide axis As. In other words, the primary rotational component of the moment of inertia caused by the swinging motion of the slide member 52D and the connecting member is greater than the primary rotational component of the moment of inertia caused by the swinging motion of the slide member 52 about the slide axis As.

[0091] FIG. 11 is a diagram showing a cross section of the slide member 52D and the first adjustment mechanism 6D along an imaginary plane including the slide axis As. 11, the cross-sectional shape of the first adjustment part 71 along an imaginary plane including the slide axis As of the slide member 52D is a shape that is symmetrical with respect to the slide axis As. The cross-sectional shape of the second adjustment part 72 along an imaginary plane including the slide axis As of the slide member 52D is a shape that is symmetrical with respect to the slide axis As. For this reason, the first adjustment part 71 of the first adjustment mechanism 6D is provided on the first piston part 524, and the center of gravity of the slide member 52D in which the second adjustment part 72 is provided on the second piston part 525 is located on the slide axis As. This makes it possible to stabilize the swinging of the slide member 52D and the connecting member 53 compared to a case in which the center of gravity of the slide member 52D is not located on the slide axis As.

[0092] [Function of the first adjustment mechanism] The magnitude of the moment generated by the swinging motion of the slide member 52D is adjusted by adjusting the outer diameter and weight of each of the first piston portion 524 and the first adjustment portion 71 centered on the slide axis As and the outer diameter and weight of each of the second piston portion 525 and the second adjustment portion 72 centered on the slide axis As. That is, the magnitude of the moment generated by the swinging motion of the slide member 52D and the connecting member 53 is adjusted by adjusting the outer diameter and weight of each of the first piston portion 524 and the first adjustment portion 71 and the outer diameter and weight of each of the second piston portion 525 and the second adjustment portion 72 centered on the slide axis As, and thus the magnitude of the first rotation component is adjusted. This makes it possible to make the magnitude of the first rotation component N equal to the product of the distance Lm and the X-axis direction component Fm. Therefore, by using the slide member 52D and the connecting member 53 in which the magnitude of the moment generated by the swinging motion has been adjusted by the first adjustment mechanism 6D, the shift in the center of gravity associated with the swinging motion of the slide member 52D and the connecting member 53 can be reduced, and ultimately vibration and noise can be reduced.

[0093] [Effects of the fourth embodiment] The electronic device according to the present embodiment described above provides the same effects as the electronic device 1 according to the first embodiment, and also provides the following effects. In the positive displacement machine 5D, the first adjustment mechanism 6D has a first adjustment part 71 extending from the first piston portion 524 along the +X direction, and a second adjustment part 72 extending from the second piston portion 525 along the +X direction. The cross-sectional shape of the first adjustment part 71 along an imaginary plane including the slide axis As of the slide member 52D is a shape symmetrical with respect to the slide axis As. Also, the cross-sectional shape of the second adjustment part 72 along an imaginary plane including the slide axis As of the slide member 52D is a shape symmetrical with respect to the slide axis As.

[0094] According to this configuration, the adjustment parts 71 and 72 are provided, so that it is possible to adjust the magnitude of the moment generated by the rocking motion of the slide member 52D having the piston parts 524 and 525, and in turn the magnitude of the primary rotation component. Therefore, it is possible to make the primary rotation component equal to the product, so that it is possible to reduce vibration and noise accompanying the rocking motion of the slide member 52D and the connecting member 53. Furthermore, since the cross-sectional shapes of the adjustment portions 71, 72 are symmetrical with respect to the slide axis As, the swinging movement of the slide member 52D on which the first adjustment mechanism 6D is provided can be stabilized.

[0095] [Fifth embodiment] Next, a fifth embodiment of the present disclosure will be described. The electronic device according to this embodiment has a similar configuration to the electronic device 1 according to the first embodiment, but the configuration and arrangement of the adjustment mechanism of the volumetric machine are different. In the following description, the same reference numerals are used for parts that are the same or substantially the same as parts already described, and the description thereof will be omitted.

[0096] [Configuration of electronic devices, temperature control devices, compressors and positive displacement machines] 12 and 13 are side views of the first rotating member 54 and the second adjustment mechanism 6E included in the electronic device according to this embodiment, as viewed from the -Z direction. More specifically, Fig. 12 is a side view showing the second adjustment mechanism 6E before the position of the first balancing member 541 is adjusted, and Fig. 13 is a side view showing the second adjustment mechanism 6E after the position of the first balancing member 541 is adjusted. The electronic device according to this embodiment has the same configuration and function as the electronic device 1 according to the first embodiment, except that it further includes a second adjustment mechanism 6E shown in Figures 12 and 13. That is, the temperature adjustment mechanism, compressor, and positive displacement machine according to this embodiment have the same configuration and function as the temperature adjustment device 2, compressor 3, and positive displacement machine 5A according to the first embodiment, except that it further includes a second adjustment mechanism 6E. Although not shown in the drawings, the displacement machine according to this embodiment includes at least one first adjustment mechanism among the first adjustment mechanisms 6A, 6B, 6C, and 6D. However, this is not limited thereto, and the displacement machine according to this embodiment does not necessarily need to include the first adjustment mechanisms 6A, 6B, 6C, and 6D.

[0097] [Configuration of the second adjustment mechanism] The second adjustment mechanism 6E adjusts the product of the distance Lm and the X-axis direction component Fm by adjusting the positions of the first balancing member 541 and the second balancing member 551 with respect to the slide axis As. In other words, the second adjustment mechanism 6E adjusts the magnitude of the moment generated about the slide axis As, which is the oscillation axis. The second adjustment mechanism 6E according to the present embodiment has a first adjustment unit 73 provided on the first rotating member 54, and also has a second adjustment unit (not shown) provided on the second rotating member 55. That is, the second adjustment mechanism 6E is disposed in the mechanism chamber S1.

[0098] [Configuration of the first adjustment section] The first adjustment unit 73 corresponds to one of the second adjustment units of the second adjustment mechanism in the present disclosure, and is a part that adjusts the magnitude of the above-mentioned product related to the first balancing member 541. As shown in Fig. 10 and Fig. 11, the first adjustment unit 73 is configured to be able to adjust the position of the first balancing member 541 in the +X direction relative to the first mounting portion 542. That is, the first adjustment unit 73 adjusts the distance between the slide axis As and the first balancing member 541, thereby adjusting the magnitude of the above-mentioned product related to the first balancing member 541. Note that the second adjustment unit (not shown) corresponds to another one of the second adjustment units of the second adjustment mechanism in the present disclosure, and is a part that adjusts the magnitude of the above-mentioned product related to the second balancing member 551. The second adjustment unit is configured to be able to adjust the position of the second balancing member 551 in the +X direction relative to the second attachment portion 552. That is, the second adjustment unit adjusts the distance between the slide axis As and the second balancing member 551, thereby adjusting the magnitude of the above-mentioned product related to the second balancing member 551.

[0099] [Action of the second adjustment mechanism] As described above, as the distance between the first balancing member 541 and the slide axis As and the distance between the second balancing member 551 and the slide axis As become shorter, the product of the distance Lm and the X-axis direction component Fm becomes smaller. On the other hand, as the distance between the first balancing member 541 and the slide axis As and the distance between the second balancing member 551 and the slide axis As increase, the product increases. Therefore, by adjusting the positions of the balance members 541, 551 with respect to the slide axis As using the second adjustment mechanism 6E, the product of the distance Lm and the X-axis direction component Fm can be made equal to the primary rotation component N. This makes it possible to reduce vibration and noise accompanying the rocking motion of the slide member 52 and the connecting member 53.

[0100] [Effects of the fifth embodiment] The electronic device according to the present embodiment described above provides the following advantages in addition to the advantages of the electronic device according to the first embodiment. The positive displacement machine according to this embodiment includes a second adjustment mechanism 6E that adjusts the magnitude of the moment generated about the oscillation axis. The first rotating member 54 has a first balancing member 541 and a first mounting portion 542 to which the first balancing member 541 is attached and which is connected to the coupling member 53. The second adjustment mechanism 6E has a first adjustment portion 73 that can adjust the mounting position of the first balancing member 541 in the +X direction along which the first rotating axis Rx1 runs. In the positive displacement machine according to this embodiment, the second rotating member 55 has a second balancing member 551 and a second mounting portion 552 to which the second balancing member 551 is attached and which is connected to the coupling member 53. The second adjustment mechanism 6E has a second adjustment portion (not shown) that is capable of adjusting the mounting position of the second balancing member 551 in the +X direction along which the second rotation axis Rx2 runs. Each of the first adjustment unit 73 and the second adjustment unit corresponds to a second adjustment unit included in the second adjustment mechanism.

[0101] According to this configuration, by adjusting the mounting positions of the balance members 541, 551, the distance between the slide shaft As and the first balance member 541 and the distance between the slide shaft As and the second balance member 551 can be adjusted. This makes it possible to increase or decrease the product of the distance Lm and the X-axis direction component Fm, so that the primary rotation component N can be made equal to the product. Therefore, the vibration and noise accompanying the swinging motion of the slide member 52 and the connecting member 53 can be reduced.

[0102] [Modifications of the embodiment] The present disclosure is not limited to the above-described embodiments, and modifications and improvements within the scope that can achieve the object of the present disclosure are included in the present disclosure. In the first to third embodiments, the first adjustment mechanisms 6A, 6B, and 6C are provided on the connecting member 53, in the fourth embodiment, the first adjustment mechanism 6D is provided on the slide member 52D, and in the fifth embodiment, the second adjustment mechanism 6E is provided on each of the rotating members 54 and 55. Of the first adjustment mechanisms 6A, 6B, 6C, and 6D and the second adjustment mechanism 6E, two or more adjustment mechanisms may be applied to a positive displacement machine. For example, one of the first adjustment mechanisms 6A, 6B, and 6C and the first adjustment mechanism 6D may be applied to a positive displacement machine. Also, for example, as described above, one of the first adjustment mechanisms 6A, 6B, 6C, and 6D and the second adjustment mechanism 6E may be applied to a positive displacement machine.

[0103] In each of the above embodiments, the slide member 52, 52D includes the first piston portion 522, 524 and the second piston portion 523, 525. However, this is not limited thereto, and the slide member may be configured to include one piston portion. For example, if the slide member does not include the second piston portion, the positive displacement machine does not need to include the second guide portion and the second pressure chamber.

[0104] In each of the above embodiments, the positive displacement machine 5A, 5D includes the first rotating member 54 and the second rotating member 55, and the compressor 3 includes the first driving device 41 including the first rotor 411 that rotates the first rotating member 54, and the second driving device 42 including the second rotor 421 that rotates the second rotating member 55. However, the present invention is not limited to this, and the positive displacement machine may include one rotating member, and the compressor may include one driving device. In this case, it is only necessary that the primary rotation component of the moment due to the inertial force accompanying the rocking motion of the slide member and the connecting member around the slide axis As is equal to the product of the distance between the slide axis As and a balance member provided on one rotating member and the X-axis component of the centrifugal force of the one balance member. Also, the compressor of the present disclosure may include one driving device and one positive displacement machine, and the positive displacement machine may have a transmission unit such as a gear that transmits the rotational force of one shaft member rotated by the driving device, and the transmission unit may rotate two rotating members 54, 55. In this case, the manufacturing cost of the compressor can be reduced.

[0105] In each of the above-described embodiments, the positive displacement machine 5A, 5D constitutes the compressor 3 together with the drive device 4. However, this is not limited to this, and the present disclosure may be applied to a positive displacement machine used in an internal combustion engine such as an engine. In other words, the positive displacement machine of the present disclosure is not limited to one that constitutes a compressor. In each of the above embodiments, the compressor 3 compresses a working fluid that changes phase between a liquid phase and a gas phase. However, the gas compressed by the compressor of the present disclosure is not limited to a working fluid as a refrigerant. In addition, the compressor 3 constitutes the temperature adjustment device 2. However, the present disclosure is not limited to this, and the compressor of the present disclosure may constitute another device or may be used alone.

[0106] In each of the above embodiments, the temperature adjustment device 2 is a device that adjusts the temperature of the temperature adjustment target CT by circulating a working fluid that changes phase between liquid and gas phases. However, the present invention is not limited to this, and the temperature adjustment device 2 according to each of the above embodiments may be configured to function as a drying device. In this case, the drying device includes a compressor, a condensation section, an expansion section, an evaporation section, and a plurality of connection pipes, similar to the temperature adjustment device, and the condensation section functions as a drying section by dissipating heat absorbed in the evaporation section in the condensation section.

[0107] [Summary of this disclosure] The following is a summary of this disclosure. [Appendix 1] a housing having a receiving section in which a mechanism chamber containing lubricating oil is provided and a cylindrical guide section in which a pressure chamber is provided; a slide member having a shaft portion, a part of which is disposed within the mechanism chamber and extends along a first direction, and a piston portion, which is provided at an end of the shaft portion in the first direction and is disposed within the guide portion, and which slides along the first direction; a connecting member disposed in the mechanism chamber and connected to the slide member; a first rotating member that is disposed in the mechanism chamber and connected to one end of the connecting member, and that rotates about a first rotation axis along a second direction that intersects with the first direction; a first adjustment mechanism that adjusts a magnitude of a moment generated by a swing movement of the slide member about a swing axis along the first direction, The positive displacement machine, wherein the first adjustment mechanism is disposed inside at least one of the mechanism chamber and the pressure chamber.

[0108] According to this configuration, the first adjustment mechanism can increase or decrease the moment generated by the swinging motion of the slide member connected to the connecting member, and thus can increase or decrease the moment generated by the swinging motion of the slide member and the connecting member. Therefore, the primary rotational component of the moment of inertia force caused by the swinging motion of the slide member and the connecting member can be made equal to the product of the distance between the slide shaft and the first rotating member and the second direction component of the centrifugal force of the first rotating member. This can reduce vibration caused by the swinging motion of the slide member and the connecting member caused by the rotation of the first rotating member. In addition, because the adjustment mechanism can reduce vibrations caused when the sliding member and the connecting member swing, there is no need to provide a weight that rotates around the first rotating shaft on the side of the first rotating shaft opposite the connecting member with respect to the first rotating member. This makes it possible to reduce the size of the displacement machine in the second direction. This allows the displacement machine to be made more compact.

[0109] [Appendix 2] 2. The positive displacement machine according to claim 1, The first adjustment mechanism is provided on the connecting member, The first adjustment mechanism includes: A base portion connected to the slide member; a first adjustment portion extending from the base portion in a third direction intersecting the first direction and in a direction opposite to the third direction, A volumetric machine, characterized in that a cross-sectional shape of the first adjustment part along an imaginary plane including the slide axis of the slide member and the third direction is a shape that is symmetrical with respect to the slide axis. According to this configuration, the cross-sectional shape of the adjustment part is symmetrical with respect to the slide axis, which makes it possible to stabilize the swinging movement of the connecting member provided with the first adjustment mechanism, thereby reducing vibrations caused by the swinging movement of the connecting member and the slide member.

[0110] [Appendix 3] 3. The positive displacement machine according to claim 2, The first adjustment unit is a first portion extending from the base portion in the third direction; a second portion extending from the base portion in a direction opposite to the third direction, a center of gravity position of the first portion is located in the third direction with respect to a center position of the first portion in the third direction; A volumetric machine, characterized in that the center of gravity of the second part is located in a direction opposite to the third direction with respect to a center position of the second part in the direction opposite to the third direction.

[0111] According to this configuration, since the adjustment portion has the first portion and the second portion, it is easy to configure the cross-sectional shape of the adjustment portion to be symmetrical with respect to the slide axis. In addition, since the center of gravity of each of the first and second parts is located at the above position, the moment generated by the swinging motion of the slide member to which the connecting member is connected can be made larger than when the center of gravity of at least one of the first and second parts is located closer to the base part than the center position. Therefore, it is possible to easily make the upper rotational primary component equal to the above product, and it is possible to reduce vibration and noise caused by the swinging motion of the slide member and the connecting member.

[0112] [Appendix 4] In the positive displacement machine according to claim 2 or 3, the third direction intersects with the second direction, The first adjustment unit is a pair of extending portions extending in the third direction and a direction opposite to the third direction, and a pair of weight portions disposed at respective tips of the pair of extension portions.

[0113] According to this configuration, the third direction is a direction that intersects the slide shaft and intersects the direction from the slide shaft toward the connection portion between the connecting member and the first rotating member. Therefore, the pair of extensions do not interfere with the connection between the connecting member and the first rotating member. In addition, the magnitude of the moment can be easily adjusted by adjusting the position and weight of the weight portion provided at the tip of each extension. In addition, the lubricating oil in the mechanism chamber can be stirred by the adjusting unit. With this configuration, the displacement machine can be operated smoothly.

[0114] [Appendix 5] In the positive displacement machine according to claim 2 or 3, the third direction is a direction from the slide shaft toward a connection portion between the connecting member and the first rotating member, The first adjustment unit is a pair of extending portions extending in the third direction and a direction opposite to the third direction, and a pair of weight portions disposed at respective tips of the pair of extension portions.

[0115] According to this configuration, the magnitude of the moment can be easily adjusted by adjusting the position and weight of the weight portion provided at the tip of each extension portion. In addition, the dimensions of the first adjustment mechanism in the directions perpendicular to the first direction and the third direction can be reduced, which makes it possible to reduce the volume of the mechanism chamber in which the first adjustment mechanism and the connecting member are disposed, thereby enabling the volumetric machine to be made more compact.

[0116] [Appendix 6] In the positive displacement machine according to claim 2 or 3, The first adjustment unit is A first arc portion having a center on the slide shaft; a second arc portion disposed on the opposite side to the first arc portion and centered on the slide shaft. With this configuration, the center of gravity of the entire connecting member can be easily aligned with the slide shaft. In addition, the moment of the connecting member can be increased while stabilizing the swinging motion of the connecting member, and therefore the swinging motion of the connecting member and the slide member.

[0117] [Appendix 7] 2. The positive displacement machine according to claim 1, the first adjustment mechanism has a first adjustment portion extending from the piston portion along the first direction, A volumetric machine, characterized in that the cross-sectional shape of the first adjustment part along an imaginary plane including the slide axis of the slide member is a shape that is symmetrical with respect to the slide axis.

[0118] According to this configuration, since the adjustment part is provided, it is possible to adjust the magnitude of the moment generated by the rocking motion of the piston part, and in turn the magnitude of the primary rotation component. Therefore, it is possible to make the primary rotation component equal to the product, thereby reducing vibration and noise caused by the rocking motion of the sliding member and the connecting member. Furthermore, since the cross-sectional shape of the adjustment portion is symmetrical with respect to the slide axis, it is possible to stabilize the swinging movement of the slide member on which the first adjustment mechanism is provided.

[0119] [Appendix 8] 8. A positive displacement machine according to any one of claims 1 to 7, Further comprising a second adjustment mechanism for adjusting the magnitude of the moment generated around the pivot shaft, The first rotating member is A first balancing member; a first attachment portion to which the first balance member is attached and which is connected to the connecting member; The second adjustment mechanism has a second adjustment part that is capable of adjusting an attachment position of the first balance member in the second direction.

[0120] According to this configuration, the distance between the slide shaft and the first balance member can be adjusted by adjusting the mounting position of the first balance member. This allows the product to be increased or decreased, so that the primary rotation component and the product can be made equal. Therefore, vibration and noise caused by the swinging motion of the slide member and the connecting member can be reduced.

[0121] [Appendix 9] A positive displacement machine according to any one of claims 1 to 8, A drive device that rotates the first rotating member, The piston portion compresses gas that has flowed into the pressure chamber. With this configuration, it is possible to obtain the same effects as the positive displacement machine described above, and it is possible to reduce vibration and to configure a compact compressor.
