By doing so, Change the volume of the air chamber, and The leaf chamber but Capacity space Can be stretched By being able to change , forming a variable suction and discharge pump death, And at least Two By connecting variable suction and discharge pumps, an active-passive drive system is constructed, and based on the principle that the driving force and load resistance must reach a mechanical equilibrium, a variable speed drive system is constructed that automatically adjusts the rotational speed ratio between the active and passive pumps during operation. [Background technology]

[0002] Common pumps are roughly divided into two types: fixed suction and discharge pumps and variable suction and discharge pumps. Of these, variable suction and discharge pumps are widely used in related industries due to their wide applicability. Furthermore, they can be roughly divided into two types according to their structure: piston type variable suction and discharge pumps and impeller type variable suction and discharge pumps. Of these, piston type variable suction and discharge pumps are usually formed by an oil pump cylinder that sequentially pushes and moves multiple pistons arranged almost parallel to each other as a variable angle swash plate rotates. As shown in Figure 1, impeller type variable suction and discharge pumps mainly include a blade rotor 10 and an eccentric ring 11 inside the pump 1. One side of the eccentric ring 11 uses an eccentricity adjustment element 12 to adjust the relative eccentricity between the blade rotor 10, and by utilizing the adjustable eccentricity, the fluid accommodation space between the blade rotor 10 and the eccentric ring 11 can be adjusted, and the pump's intake and discharge volume can be adjusted.

[0003] However, since the eccentric ring 11 is installed inside the pump 1, it is not adjustable. The amount of displacement is limited within a fixed space within the pump shell, and the size of the internal space is directly affected and limited by the radial dimensions of the pump body and all of its components. Therefore, when it is necessary to manufacture products with different maximum suction and discharge capacities for different applications, the commonality of parts between pumps with different suction and discharge capacities is low, so each time a new pump with a new maximum suction and discharge capacity is manufactured, multiple parts must be redesigned and remolded, resulting in relatively high manufacturing costs. In addition, if the distance between the suction and discharge sides of the pump is long during operation, the pressure difference between the two sides will be too large, and the radial expansion and contraction movement of each blade during operation will be too large, which may result in undesirable effects such as vibrations and noise caused by collisions. Summary of the Invention [Problem to be solved by the invention]

[0004] In view of the shortcomings of the conventional variable suction and discharge pumps described above, an object of the present invention is to provide a new impeller-type variable suction and discharge pump, and in particular, by providing the leaf chamber of the pump with a function that enables the volume space to be adjusted by expanding and contracting along the axial direction of the blade rotor, it is possible to increase or decrease the suction and discharge volume per unit circulation volume of the fluid inside the pump by changing the leaf chamber space in the axial direction. Therefore, when it is necessary to manufacture pumps with different suction and discharge volumes, the preparation costs for manufacturing pumps with different suction and discharge volumes can be significantly reduced by increasing commonality by aligning the radial dimensions of each part, and further, increasing the maximum suction and discharge volume of the pump can be achieved by simply changing the axial dimensions of the pump and related parts. do.

[0005] Furthermore, based on the design of the variable intake / discharge pump of the present invention, if at least Two Two corresponding fluid inlet and outlet paths are connected between the correspondingly arranged variable suction and discharge pumps. I will CombinationWhen a closed active-passive driving circuit is formed, when a difference occurs between the driving force of the active pump and the load resistance of the passive pump during the driving operation of the circuit, the expandable leaf chamber of the leaf chamber body is subjected to the driving action of the difference force, and the size of the leaf chamber of the active pump and the size of the leaf chamber of the passive pump are automatically adjusted to expand and contract until the driving force for the fluid in the active pump and the load resistance for propelling the fluid in the passive pump are balanced, and at the same time, Any Within the same moment Active and passive pumps Fluid intake and output but Almost Equal Good driving Under the conditions, The aforementioned active Pump and Passive Pump Between Leaf chamber volume and rotation speed teeth Inversely proportional automatically equilibrium Automatic balancing ensures stable operation.

At least two intake and exhaust passage openings are provided, and at least one of the intake and exhaust passage openings is At least one of the intake and exhaust blades communicates with the intake side and the exhaust side of the blade. All of the passage openings are in communication with the leaf chambers.

[0012] In the above-mentioned variable suction and discharge pump, a sealing block is provided at the part where the blade, the movable wall member, and the movable leaf chamber sleeve come together at the same time, thereby creating a gap at the intersection of the three (the upper edge of the blade, the movable wall member, and the movable leaf chamber sleeve) to prevent leakage of the fluid in the leaf chamber.

[0013] According to the above variable speed drive device, at least one variable pump is connected to the pump. a variable intake / exhaust amount drive device, and each deflection link on the intake side of all the blades of the variable intake / exhaust amount drive device The total area of the movable wall surface included in the blade chamber area is The area is equal to the sum of the areas of the movable wall surfaces included in the leaf chamber area.

A variable intake / exhaust volume drive device is configured, and four times the number of blades are provided in each of the variable intake / exhaust volume drive devices. and a number of offset leaf chamber areas equal to or greater than the number of said blades. Each blade in the variable drive unit is at an angle of 180 degrees to the other blades. They have a complementary relationship.

[0015] According to the above variable speed drive device, at least one variable suction / discharge pump is connected to actuate the and a variable pump is connected to the variable pump. and then connecting the active pump and the passive pump. This constitutes an active-passive closed-loop variable speed drive.

[0018] According to the above variable speed drive device, the leaf chamber of the active pump increases. 、 and the leaf chamber contraction direction of the passive pump 、 of Both One of them will be installed with an additional displacement resistance element.

[0019] According to the above variable speed drive device, the active pump has a plurality of variable suction and discharge pumps. All variable pumps are driven synchronously by common related components. The passive pump is composed of a plurality of variable suction and discharge pumps, and is connected to common related members. Therefore, all of the variable suction and discharge pumps are driven synchronously.

[0020] By applying the above-mentioned variable intake and exhaust volume drive device and its drive method, A drive unit is configured from at least one of the variable suction / discharge pumps, and a fluid is supplied to the drive unit. The fluid enters the leaf chamber of the blade. The blades propel one side of the rotor and drive the rotor's rotation. The fluid on the other side of the blade in the leaf chamber is pushed out of the leaf chamber, The driving circuit is formed by the movable wall member and the movable leaf chamber sleeve of the driving device. The blade rotor is displaced synchronously relative to the fixed wall along the axial direction of the blade rotor, thereby When changing the size of the leaf chamber of the drive unit, With each revolution of the bladed rotor, the amount of fluid expelled and drawn in changes accordingly. and the volume of the leaf chamber is required to flow a certain amount of fluid per unit time. As the volume increases, the rotation speed of the blade rotor decreases, and the volume of the blade rotor decreases. When the rotation speed of the blade rotor becomes smaller, the rotation speed of the blade rotor becomes faster. The rotation speed is inversely proportional to the size of the modified leaf chamber volume.

[0021] According to the above-mentioned variable intake / exhaust amount drive device and its driving method, the movable wall and the movable By forcibly pressing at least one of the leaf chamber sleeves with an external force, The movable wall member and the movable leaf chamber sleeve are synchronized in the axial direction of the blade rotor. and displace it.

The leaf chamber of the active pump is connected to the leaf chamber of the active pump to form a closed drive circuit. When the change in the volume of the valve increases and the amount of fluid in the closed circuit remains constant, the passive The pump's leaf chamber volume is correspondingly reduced to allow a constant volume of fluid to flow over the same period of time. In this case, the rotation speed of the blade rotor of the active pump slows down, and the passive pump The rotation speed of the blade rotor of the pump increases, and the active pump and the passive pump The rotation speed of the blade rotor of the active pump is inversely proportional to the rotation speed of the rotor. If the leaf chamber volume is reduced, the leaf chamber volume of the passive pump will be increased accordingly. When a constant amount of fluid flows in the same time, the brake The rotation speed of the rotor increases, and the rotation speed of the blade rotor of the passive pump decreases. The rotational speeds of the blade rotors of the active pump and the passive pump are also inversely proportional to each other. Examples of relationships are presented.

[0023] According to the above variable speed pump drive device and its drive method, the active pump and the front At least one of the movable wall member and the movable leaf chamber sleeve of the passive pump By forcibly pressing the active pump and the passive pump simultaneously with an external force, The movable wall of the pump and the movable leaf chamber sleeve are synchronized in the axial direction of the blade rotor. and displacing the active pump and the passive pump by the movable wall and the movable link. The displacement distances of the air chamber sleeves are equal.

[0024] According to the above-mentioned variable speed pump drive device and its drive method, the amount of fluid in the closed circuit is constant. By utilizing this, the leaf chamber volumes of the active pump and the passive pump are changed. The magnitudes of the pumping force change synchronously and are complementary to each other. The movable wall member and the movable leaf chamber sleeve simultaneously move along the axial direction of the blade rotor. When the leaf chamber volume is reduced by moving the fixed wall relative to the fixed wall, The movable wall member and the movable leaf chamber sleeve of the passive pump also move in synchronization with the blade row. The leaf chamber volume is displaced relative to the fixed wall along the axial direction of the rotor. and the active pump and the passive pump have movable walls and movable leaf channels. The displacement distance of the movable sleeve of the active pump is the same. The blade chamber sleeve is also configured to move relative to the fixed wall along the axial direction of the blade rotor. When the leaf chamber volume is increased by displacing the pump away from the The movable wall member and the movable leaf chamber sleeve also move forward in the axial direction of the blade rotor in synchronization. the fixed wall member is displaced relatively close to the fixed wall member to reduce the leaf chamber volume; and The active pump and passive pump movable wall member and movable leaf chamber sleeve are variable. The distance between the two points is the same. [Effects of the Invention]

(two) Under the action of the difference between the driving force and the load resistance, the active pump and the passive pump The movable wall of the pump and the movable leaf chamber sleeve move the extrusion produced in the leaf chamber. The active pump and the passive pump are subjected to thrust and vacuum suction. The movable wall member and the movable leaf chamber sleeve are displaced synchronously, and the active The size of the leaf chamber volume of the pump and the passive pump is subjected to the force difference and is adjustable. Generate changes automatically. (three) In a closed circuit, the leaf chamber volumes of the active pump and the passive pump are The magnitude is determined by the force balance action, so that the driving force of the active pump is finally equal to the force of the pump. The load resistance of the active pump is automatically adjusted to be equal to the load resistance of the active pump. The size of the leaf chamber volume between the pump and the passive pump and the rotation speed are also inversely proportional to each other. The rotation is automatically adjusted.

For example, the intake and exhaust passages 343 and 344 shown in FIG. I'm doing teeth The intake and exhaust passages 343 and 344 are connected to the outside from two rotor shaft ends (including the rotor shaft end 33 and the rotor shaft end 34) of the blade rotor 3, respectively. Adopted in Example 2 of the present inventionAs shown in FIG. 11, the intake and exhaust passages 343 and 344 are connected to each other at the axial center 345 and the non-axial center 346 of the same rotor shaft end 34, respectively, and further, the external intake and exhaust port 410 installed on the base 41 and / or the frame body 4 is connected to the intake and exhaust port 410. and It can be connected to the outside via an intake / exhaust passage 4100.

[0031] The aforementioned Movable wall 22 On one end surface of A movable wall surface 221 is provided, The center position of the movable wall surface 221 The leaf chamber 2 has a sleeve hole 222 passing through the movable wall member 22. 30 is located within the movable leaf chamber sleeve 23 and A leaf chamber sleeve end surface 2302 is provided on one end surface of the movable leaf chamber 23. The leaf chamber 230 of the leaf sleeve 23 is fixed to the fixed wall seat sleeve 2 of the fixed wall member 21. 11, whereby the movable leaf chamber sleeve 23 can be engaged onto the fixed Slide on the fixed seat sleeve 211 and on the outer periphery of the impeller 30 of the blade rotor 3 The movable wall member 22 can be inserted into the blade rotor 3 through the sleeve hole 222. The sleeve hole 222 is fitted on the propeller 30 and has a slot 2221 formed on the periphery thereof. The slots 2221 correspond to the positions of the blades 31 mated on the impeller 30, This allows the blade 31 to extend and slide into the slot 2221. The movable wall member 22 can be on the impeller 30, The movable wall surface 221 The above The movable leaf chamber sleeve 23 is in close contact with the leaf chamber sleeve end surface 2302. To do in , the movable wall member 22 and the movable leaf chamber sleeve 23 synchronize with the blade rotor 3 axial movement, the volume space of the leaf chamber 230 is changed, When the movable wall member 22 approaches the fixed wall member 21 in the axial direction, The plurality of A greater portion of the blade 31 can be slidably accommodated within the slot 2221; and The volume of the leaf chamber 230 is reduced. When the blades 31 are spaced apart from the wall 21 in the axial direction, a relatively small portion of the blades 31 can slide into the slot 2221, and the leaf chamber 230 The capacity space becomes larger. The leaf chamber 230 includes a movable leaf chamber sleeve 23 and a Fixed wall 204 , the movable wall surface 221, and the blade rotor 3; and The aforementionedBy subtracting the remaining space of the leaf chamber 230 occupied by the impeller 30, at least one offset leaf chamber area 2301 can be formed, which is offset from the axis of the blade 3. The blade 31 is in close contact with the inner wall of the leaf chamber 230, away from the upper blade edge 311 of the blade rotor 3, and can slide axially and / or circumferentially relative to the inner wall of the leaf chamber 230. In addition, the contact points between the blade 31 and the inner wall of the leaf chamber 230, and the contact points or relative displacement points of the fixed wall member 21, the movable wall member 22, the movable leaf chamber sleeve 23, and the blade rotor 3 can all be provided with suitable sealing and leak-proof elements to prevent the fluid in the leaf chamber 230 from leaking from these points during operation. In particular, at the intersection of the upper edge 311 of the blade 31, the movable wall member 22, and the movable leaf chamber sleeve 23, the outer surface curve of the upper edge 311 is different from the cross-sectional curve of the upper edge 311 passing through the slot 2221 of the movable wall member 22, and the inner wall curve of the leaf chamber 230 of the movable leaf chamber sleeve 23 that contacts the upper edge 311 of the blade, so there is a small gap at the intersection, and as a result, the leaf chamber 230 cannot be completely sealed during operation. For this reason, the present invention provides a sealing block 37 on the upper edge 311 of the blade, which is capable of sliding synchronously with the upper edge 311 of the blade 31 in close contact with the upper edge 311 of the blade 31. The sealing block 37 is further confined within the intersecting path of the slot 2221 of the movable wall member 22 and the outer edge of the inner wall of the leaf chamber 230 of the movable leaf chamber sleeve 23. Thus, during operation, the intersecting points of the upper edge 311 of the blade, the slot 2221, and the outer edge of the inner wall of the leaf chamber 230 can be sealed at any time, thereby generating a good sealing and leak-proof effect for the gap. The movable wall member 22 and the movable leaf chamber sleeve 23 can be coupled using a fixing member 5 (the structure of the fixing member 5 can have various possible forms, but detailed description thereof is omitted here), thereby maintaining the two components sliding synchronously in the axial direction in a bonding relationship with each other.

[0032] According to the above combined structure, when the blade rotor 3 drives the blades 31 to sweep in the deflection leaf chamber area 2301 during operation, the fluid located on the forward side of the blades 31 in the sweep direction is pushed out and discharged to form the discharge side, and the other side of the blades 31 The vacuum suction force generated after scanning sucks in the fluid to form the suction side. The movable wall member 22 is fitted to the impeller 30 of the blade rotor 3, and the fixed wall member The movable leaf chamber sleeve 23 is fitted onto the leaf sleeve 211, and the brake Draco 3 Axial Along Displacement can be As the movable wall surface 221 gradually approaches the fixed wall surface 204 in the axial direction, the suction and discharge capacity of the deflection leaf chamber area 2301 gradually decreases relatively, and conversely, as the movable wall surface 221 gradually moves away from the fixed wall surface 204 in the axial direction, the suction and discharge capacity of the deflection leaf chamber area 2301 gradually increases, thereby forming a variable suction and discharge pump that can expand and contract in the axial direction to change the suction and discharge volume of the leaf chamber 230.

[0033] Therefore, when the above variable suction and discharge pump is applied, fluid Incorporating it into a closed circuit, and, external force (For example, the external force shown in Figure 5) Using the forced propulsion of In contrast Pressure changes Generate The propulsion action is performed by the movable wall member 22 and the movable leaf chamber sleeve 23. of Both home There is at least one of the movable wall member 22 and the movable leaf chamber sleeve 23. is the above Fixed wall 21 To move towards or away from This causes a displacement and further increases the volume of the leaf chamber 230. space By changing the magnitude of 、 The rotation of the blade rotor 3 The aforementioned The output and input volumes of fluid forced through the leaf chamber 230 vary in response to changes in the volume of the leaf chamber 230. Furthermore, the above The blade rotor 3 changes in response to the change in the volume of the leaf chamber 230. 、 Generates power transmission at different speeds and form a variable intake / exhaust volume drive device. .

[0034] 7, the variable intake / exhaust pumps formed based on the above are arranged in a corresponding manner and communicate with each other, and the intake and exhaust paths set in the first intake / exhaust path 351 and the second intake / exhaust path 352 of the two correspondingly arranged pumps are crossed and communicated with each other. Thus, among the two correspondingly arranged pumps, the one located on the left side of the figure is set as the active pump 101, and the other pump on the right side is set as the passive pump 102, and the exhaust path of the active pump 101 is connected to the intake path of the passive pump 102, The aforementioned Active Pump 101 The fluid on the discharge side of the blade 31 is Discharge from the outlet passage Let , The aforementioned It enters the suction port passage of the passive pump 102 and the suction side of the blade 31. The aforementioned The outlet passage of the passive pump 102 is connected to the suction passage of the active pump 101, and the fluid on the discharge side of the blade 31 of the passive pump 102 is the The air is discharged from the outlet passage and flows into the suction passage of the active pump 101 and the suction side of its blade 31, so that the leaf chambers of both the active pump 101 and the passive pump 102 and the entire suction and discharge passages form a closed circuit in which the active pump 101 drives the passive pump 102, and the active pump 101 and Passive pump 102 movable wall element 22 and Movable leaf chamber sleeve 23 of Both home At least one of the active pumps 101 can be connected by a same-direction displacement connecting member 80. andThe movable wall member 22 of the passive pump 102 can move on the same axis together with the movable leaf chamber sleeve 23. During operation of the active-passive closed circuit, if the fluid used is a liquid fluid and the total liquid volume is constant, the liquid fluid on the discharge side in the bias leaf chamber area 2301 of the active pump 101 is pushed to the suction side of the passive pump 102 by the blades 31 as the blade rotor 3 rotates. On the other hand, the liquid fluid on the discharge side in the bias leaf chamber area 2301 of the passive pump 102 is also pushed to the suction side of the active pump 101 by the blades 31 as the blade rotor 3 rotates, thereby forming a complete active-passive liquid fluid driving circuit. do.

[0035] The above When the drive circuit is operating, the driving force of the active pump 101 rotates its blade rotor 3 and the The blade 31 is driven, and a thrust pressure is applied to the movable leaf chamber sleeve 23 located on the discharge side of the blade 31 in the deflection leaf chamber area 2301 of the active pump 101, the fixed wall surface 204, and the movable wall surface 221, and the leaf surface of the blade 31 located on the suction side of the blade 31 in the deflection leaf chamber area 2301 of the passive pump 102, the movable leaf chamber sleeve 23, the fixed wall surface 204, and the movable wall surface 221. do. at the same time , the blades 31 of the active pump 101 are deflected. To generate a vacuum suction force after propelling and scanning the leaf chamber area 2301, The movable leaf chamber sleeve 23, the fixed wall surface 204, and the movable wall surface 221 located on the suction side of the blade 31 in the deflection leaf chamber area 2301 of the active pump 101, and the leaf surface of the blade 31, the movable leaf chamber sleeve 23, the fixed wall surface 204, and the movable wall surface 221 located on the discharge side of the blade 31 in the deflection leaf chamber area 2301 of the passive pump 102, towingThe direction of the driving pressure or vacuum suction force that the movable leaf chamber sleeve 23 receives is exactly perpendicular to the direction in which the movable leaf chamber sleeve 23 can move axially, so the driving pressure or vacuum suction force cannot directly displace the movable leaf chamber sleeve 23, and the fixed wall surface 204 is fixed and cannot move, so that only the movable wall surface 221 moves in the driving process. Multiple Driving pressure or vacuum suction force Leading Received By doing so, The movable wall member 22 is moved in the axial direction. Also The movable leaf chamber sleeve 23 is connected to the movable wall member 22 along with Synchronize the fixed wall Moving towards or away from the surface 204 Move in the axial direction At this time, The blades 31 in the passive pump 102 The suction side is Propulsion pressure On the other hand, the emission side Vacuum suction power Under the tow, the blade 31 Double in the same direction Under biasing action , and drives the rotational motion of the blade rotor 3, and further outputs power to the load end of the passive pump 102.

[0036] The above drive circuit At the start of driving, the passive pump 102 is still stationary and immobile, and the blade rotor 3 of the active pump 101 begins to rotate due to the driving force. the The liquid fluid located on the discharge side of the blade 31 begins to be pushed out. If the area of the movable wall surface 221 located on the discharge side of the blade 31 in the deflection leaf chamber area 2301 of the active pump 101 is greater than the area of the movable wall surface 221 located on the suction side of the blade 31 in the deflection leaf chamber area 2301 of the passive pump 102, the larger the stress area, the greater the force. Propelled pressure becomes larger, And this time, The blades 31 of the passive pump 102 Supported by load resistance For this reason, Pressure is received The force is pushed toward the movable wall surface 221 of the active pump 101, which has a relatively large area. The active pump 101 includes a movable wall member 22, a movable leaf chamber sleeve 23, and a Xu along the axial direction of the blade rotor 3A displacement is generated in the direction away from the fixed wall surface 204, expanding the axial space of the deflection leaf chamber area 2301, and at the same time, vacuum The vacuum suction force generated by the active pump 101 on the suction side of the blade 31 in the deflection leaf chamber area 2301 is smaller than the area of the movable wall surface 221 on the discharge side of the blade 31 in the deflection leaf chamber area 2301 of the passive pump 102, so that the larger area of the movable wall surface 221 in the passive pump 102 after the blade 31 sweeps creates a larger suction pulling force on the larger area of the movable wall surface 221 in the passive pump 102, causing the movable wall surface 22 of the active pump 101 to be displaced away from the fixed wall surface 204 together with the movable leaf chamber sleeve 23, and the movable wall surface 22 of the passive pump 102 to be displaced together with the movable leaf chamber sleeve 23 in the direction toward the fixed wall surface 204. Similarly, when the area of the movable wall surface 221 located on the discharge side and the suction side of the blade 31 in the displacement leaf chamber area 2301 of the active pump 101 and the passive pump 102 is compared and found to be opposite to the above, the movable wall member 22 and the movable leaf chamber sleeve 23 of the active pump 101 and the passive pump 102 are displaced in the opposite direction. Blade rotor 3 Axial direction Along The reciprocating movement continues, and the liquid fluid originally located in the passages on the suction side of the blades 31 of the active pump 101 and the discharge side of the blades 31 of the passive pump 102 is converted by the driving loop and replaced into the passages on the discharge side of the blades 31 of the active pump 101 and the suction side of the blades 31 of the passive pump 102, respectively. After replacement, the volume of the liquid fluid in the passages is ,ifWhen the discharge side of the blade 31 of the active pump 101 and the suction side of the blade 31 of the passive pump 102 have already moved in the axial direction and the total volume is larger than the adjustable maximum volume, and Between the passive pumps 102, due to the traction of the respective same-direction displacement connecting members 80 and the incompressibility of the liquid, as the blades 31 of the active pump 101 are driven, the thrust of the liquid fluid is all received by the leaf surfaces on the suction side of the blades 31 in the passive pumps 102, which further gradually propels the passive pumps 102 and their load ends, thereby gradually operating the closed circuit of the active-passive pumps.

[0037] Therefore, the above A closed fluid circuit combined by Applying this, external force forcing element 8 By using The aforementioned Multiple Movable wall member 22 and movable leaf chamber sleeve 23 of Both home At least one of Forced promotion, Alternatively, the active pump 101 and the passive pump Pump 102 generates a driving pressure and vacuum suction within its respective leaf chamber 230. By being subjected to the pulling force, The movable wall member 22 and the movable leaf chamber sleeve 23 but, The fixed wall member 21 Approaching or moving away from causing a displacement and further changing the volume size of the leaf chamber 230; In this way The active pump 101 and the passive pump 102 each pump a volume of the leaf chamber 230 in response to a change in the volume of the leaf chamber 230. before The active pump 101 and the passive pump 102 each The leaf chamber volume and of The rotation speed of the blade rotor 3 is inversely proportional to to change and the active pump 101 The change in the leaf chamber volume between the passive pump 102 and the passive pump 102 is complementary. , the rotation of the blade rotor 3 between the active pump 101 and the passive pump 102 The speed is inversely proportional .

[0038] The active Pump and During the operation of the passive pump circuit, the active pump 101, the movable wall member 22 of the passive pump 102 and the movable leaf chamber sleeve 23 is blurred Draco 3 Axial direction Along round trip doConditions that cause sustained displacement Because , the rotation of the passive pump 102 motion In the above embodiment, The aforementioned In active and passive pumps, a single deviation Leaf Chamber Area 2301 and a single blade 31 and If the above Passive Pump 102 At initial startup, the blade 31 All blade rotors 3 Fit inside It is a state , child When Passive Pump 102 Driven by the internal force Blade 31 Because there is no leaf surface, The aforementioned Active Pump 101 is always in an ineffective idle state, The aforementioned Passive Pump 102 In order to avoid the situation where the circuit generates the above sudden, slow or invalid operation, two Variable suction and discharge pump formed The active pump 101 (or the active pump 101 with twice the number of deflection leaf chamber areas 2301) is Variable suction and discharge pump accomplished 7-2 shows a combination configuration for connecting to a passive pump 102 (or a passive pump 102 having twice the number of deflection leaf chamber areas 2301), and Suction / discharge amount possible Variable pump formed The active pump 101 (or the active pump 101 having four times the number of deflection leaf chamber areas 2301) is Variable suction and discharge pump formed a combination configuration in connection with a passive pump 102 (or a passive pump 102 having four times the number of deflection leaf chamber areas 2301); Active pumps formed by multiple variable pumps The passive pump 101 or the passive pump 102 formed by multiple variable suction and discharge pumps is All bias leaf chamber areas in the active pump 101 and passive pump 102 The sum of the areas of the movable wall surfaces 221 on the intake side and the sum of the areas of the movable wall surfaces 221 on the discharge side is The active pumps 101 and the passive pumps 102 are very close or equal to each other. 102 can maintain the total volume of the intake side at any time during the operation, The volumes can be made very close or equal to the sum of the volumes on the discharge side, thus It can effectively improve the situation of each intake and exhaust The blades 31 in the variable volume pump are all symmetrical to each other, 180 degrees apart. During operation, at least one blade 31 is positioned outside the blade rotor 3. The active pump 101 and the passive pump 102 are held together by the pump 102. The variable speed drive with the pump 102 does not vibrate the blade 31 during operation. The power supply can continue to be received by the power supply surface, preventing the circuit from running idle and allowing for smoother operation. Achieve stable driving effect with .

[0039] The plurality pieces by pump The combination of the active pump 101 and the passive pump Pump 102 , and composition was In the active-passive drive circuit, especially in Figure 7-2, there are four formed by the pump An active pump 101 is coupled to four passive pumps 102 By doing so, a circuit configuration having an active pump 101 and a passive pump 102 is obtained. of combination, In an implementation, all of the deflected leaf chamber areas 2301 Sum of the area of the movable wall surface 221 corresponding to the suction side is within all deflection leaf chamber area 2301 The sum of the areas of the movable wall surfaces 221 corresponding to the discharge side of is approximately equal to four With pump do Active Pump 101 and 4 having a pump Passive pump 102 combination in, the Inside Department This is the same as the discharge and intake amounts of the liquid fluid being approximately equal, and the entire circuit can be operated continuously and stably. If the driving force of the active pump 101 changes, Without , when the load on the passive pump 102 increases, each The sweep speed of the blade 31 decreases, and the passive pump 102 Each forming Intake side of blade 31 teeth Liquid fluid By accumulating Amplified thrust is generated against the movable wall surface 221, and the passive pump 102 each The liquid fluid returning from the discharge side of the blade 31 to the suction side of each blade 31 of the active pump 101 is reduced, Aku Each of the 101 A vacuum suction force is applied to the movable wall surface 221. formation Since the sum of the surface areas of the movable wall surfaces 221 in the deflection leaf chamber areas 2301 on the discharge side and the suction side are approximately the same, the active pump 101 and Passive Pump 102 eachThe sum of the forces received by the movable wall surface 221 is approximately the same, and due to the action of the capacity-amplifying thrust of the passive pump 102 and the vacuum suction force of the active pump 101, the movable wall member 22 of the active pump 101, together with the movable leaf chamber sleeve 23, is displaced in the direction approaching the fixed wall surface 204, reducing the total pump capacity of the active pump. each The movable wall member 22, together with the movable leaf chamber sleeve 23, can be displaced away from the fixed wall surface 204, amplifying the total pumping capacity of the passive pump 102 and causing multiple power loop inputs of the active pump 101 to drive a single power loop output of the passive pump 102, creating an effect similar to a downshift drive of the power transmission. if When the driving force of the active pump 101 remains unchanged but the load of the passive pump 102 decreases, all the above operation conditions are completely reversed, resulting in a single power loop input of the active pump 101, which can drive multiple power loop outputs of the passive pump 102, generating an effect similar to a shift-up drive of the power transmission.

In addition, in the direction of increasing the leaf chamber volume of the active pump 101 in FIG. 7-3 and in the direction of decreasing the leaf chamber volume of the passive pump 102 in FIG. 7-4, the displacement resistance element 9 can be further provided. and / or A displacement resistance element 90 (e.g., a spring) can be added to provide the active pump 101 of the present invention. and The displacement resistance element 9 is automatically adjusted by the action of the rotational speed ratio value configured between the passive pumps 102. and / or A preset internal load resistance of the displacement resistance element 90 can be generated, and a preset balance condition can be created in which the driving force that actually needs to be input is slightly greater than the load resistance that is actually applied, thereby simulating the forced downshift effect of a transmission mechanism.

The driving method is as follows: (1) operating the variable speed drive device and generating a difference between the driving force of the active pump and the load resistance received by the passive pump; (2) The size of the leaf chamber of the active pump and the size of the leaf chamber of the passive pump are automatically adjusted according to the difference between the driving force and the load resistance; (3) A driving method using a variable speed drive device as claimed in claim 10, characterized in that, under the condition that the amount of fluid suction and discharge per unit time between the active pump and the passive pump is approximately the same, the driving force on the fluid in the active pump and the load resistance experienced by the fluid in the passive pump are made equal to achieve operational balance; and the volumes and rotational speeds of the leaf chambers between the active pump and the passive pump are automatically adjusted to achieve operation in an inversely proportional relationship; and when the effect between the driving force and the load resistance changes, the sizes of the leaf chambers of the active pump and the passive pump and the rotational speed ratio therebetween are automatically adjusted, thereby achieving operational balance between the driving force and the load resistance during operation.

12. During operation of the active-passive closed circuit, the driving force of the active pump rotates its blade rotor and moves the blades, applying a driving pressure to the movable leaf chamber sleeve located on the discharge side of the blades in the deflection leaf chamber area of the active pump, the fixed wall surface on the fixed wall base and the movable wall surface on the movable wall base, and the leaf surface of the blade located on the suction side of the blades in the deflection leaf chamber area of the passive pump, the movable leaf chamber sleeve, the fixed wall surface and the movable wall surface, and simultaneously forming a driving force to the movable leaf chamber sleeve located on the suction side of the blades in the deflection leaf chamber area of the active pump, the fixed wall surface and the movable wall surface, and the leaf surface of the blade located on the discharge side of the blades in the deflection leaf chamber area of the passive pump, the movable leaf chamber sleeve, the fixed wall surface and the movable wall surface, to generate a vacuum suction force.

When the area of the movable wall surface of the movable wall member located on the discharge side of the blade in the deflection leaf chamber area of the active pump is larger than the area of the movable wall surface of the movable wall member located on the suction side of the blade in the deflection leaf chamber area of the passive pump, the movable wall member of the active pump as well as the movable leaf chamber sleeve are gradually displaced in the axial direction away from the fixed wall surface of the fixed wall member to expand the axial space of the deflection leaf chamber area, and at the same time, a suction force is generated on the suction side of the blade of the passive pump, and the movable wall member of the passive pump as well as the movable leaf chamber sleeve are displaced in the axial direction towards the fixed wall surface. At the same time, if the area of the movable wall surface located on the suction side of the blades in the deflection leaf chamber area of the active pump is smaller than the area of the movable wall surface located on the discharge side of the blades in the deflection leaf chamber area of the passive pump, the vacuum suction force generated on the suction side by the sweep of the blades of the active pump will form a large suction force on the movable wall surface in the passive pump with a larger area, causing the movable wall member of the active pump and the movable leaf chamber sleeve to be displaced in a direction away from the fixed wall surface, and the movable wall member of the passive pump and the movable leaf chamber sleeve to be displaced in a direction approaching the fixed wall surface. On the other hand, when the area sizes of the movable wall surfaces located on the discharge side and the suction side of the blades in the respective deflection leaf chamber areas of the active pump and the passive pump are opposite to those described above, the movable wall members and the movable leaf chamber sleeves of the active pump and the passive pump are displaced in the opposite direction to those described above; The driving method according to claim 12, further comprising: by pulling a co-directional displacement connecting member between the active pump and the passive pump, as the blades of the active pump are driven, the liquid fluid generates a thrust against the leaf surface on the suction side of the blades in the passive pump, gradually propelling the passive pump and its load end, and gradually operating the drive circuits of the active pump and the passive pump.
