Description

Technical Field

[0001] This invention relates to a multi-bladed suction and discharge device with axially variable volume and a variable speed drive system thereof; in particular, it relates to a multi-bladed impeller fluid suction and discharge device with axially variable blade chamber volume, and a variable speed drive system composed of the multiple suction and discharge devices. Background Technology

[0002] The use of impeller-type and piston-type suction and discharge devices (pumps) to generate variable flow rates for use in civilian or industrial machinery is an existing technology. For example, Taiwan's utility model application No. 81210979, "Improved Shape of Eccentric Ring in Variable Displacement Impeller Pump," and invention application No. 81108624, "Variable Capacity Piston Pump," are two typical feasible examples of this technology.

[0003] In addition, Taiwan's Patent Application No. 97146784, "2-Capacity Pump," discloses a pump body that combines a piston, a variable capacity mechanism, a capacity switching valve, and a telecommunications controller. It then uses a pressure compensation valve to actuate a yoke, and the perpendicular relationship between the pressing surface of the yoke and the pump shaft forms different tilt angles to change the fluid intake and discharge volume per piston stroke, thereby relatively changing the fluid intake and discharge volume per pump rotation.

[0004] In Taiwan Patent Application No. 100109749, entitled "Variable Speed ​​Hydraulic Pump Device and Method," a method is disclosed in which a first pump and a second pump are respectively connected to a first motor with a fixed rotational speed and a second motor with a variable speed. A speed control valve is used to control the suction and discharge flow of fluid between the two pumps. The speed control valve drives a linear shaft to change position via a guide to increase or decrease the amount of fluid transmitted from the first pump to the second pump, thereby changing the rotational speed of the second pump and relatively increasing or decreasing the speed of the second motor.

[0005] Therefore, as those skilled in this art know, the suction and discharge capacity of a pump unit can be influenced by the radial dimensions of its internal space or by external control mechanisms. However, in applications where different suction / discharge capacities need to be manufactured, the different design diameters often result in a low proportion of components that can be shared between products. This means that before producing pump units of different specifications, a considerable amount of time must be spent redesigning and re-molding the components for the new specifications. Furthermore, when enlarging or reducing the size of these components, issues such as their corresponding combination relationships and precision requirements must be reconsidered, significantly increasing the production time required and directly raising product development and manufacturing costs.

[0006] Therefore, regarding the structure and application techniques of traditional pumps or fluid suction / discharge devices, if they possess the function of randomly varying suction / discharge volume and make the radial specifications between components more consistent, thereby improving the component commonality between products with different rated suction / discharge capacities, the preparation time and production costs can be significantly shortened before changing the production of suction / discharge devices with different suction / discharge capacities. The inventors of this case have further discovered that if the variable volume characteristic of the suction / discharge device can be further utilized, and the components are combined into an active-passive system, the driving force of the active system and the load resistance of the passive system can be naturally applied to automatically achieve a balance during operation. This allows the active and passive systems to generate an automatic adjustment of the speed ratio between the active and passive systems based on the inverse relationship between suction / discharge capacity and rotational speed. The application range of these multiple fluid suction / discharge devices will be much wider; moreover, these issues have clearly not yet been specifically disclosed and / or proposed for application in the aforementioned references.

[0007] Based on the above findings, the inventor of this case previously filed a patent application (Taiwan) No. 10910949, entitled "Variable Suction / Discharge Pump, Drive Device Composed of the Pump and Drive Method Thereof" (hereinafter referred to as the prior application). The main objective of this prior application was to provide a novel impeller-type variable capacity suction / discharge device (pump), specifically by configuring the impeller chamber capacity of the suction / discharge device to be adjustable along the axial direction of its rotor blades. This allows the single-cycle suction / discharge volume of the working fluid inside the suction / discharge device to increase or decrease due to axial changes in the impeller chamber space. Therefore, when manufacturing suction / discharge devices with different rated suction / discharge volumes, the radial specifications of each component can be designed to be consistent, which is beneficial for… By increasing the commonality between them, the material preparation cost of manufacturing devices with different suction and discharge capacities can be significantly reduced. Moreover, when the maximum suction and discharge capacity requirement of the suction and discharge device increases or decreases, it is only necessary to increase or decrease the axial dimension of the suction and discharge device and related components according to the axial direction of the blade rotor, without having to change the radial dimension of the blade chamber to meet the changing needs of the overall suction and discharge capacity. This can fully solve the aforementioned shortcomings of the traditional method. Furthermore, since the radial dimension of the blade chamber can be effectively controlled, the radial dimension and extension stroke of the blades can also be effectively controlled within a small range, so that the noise caused by the rapid back and forth extension and retraction of the blades in the blade chamber during operation can be effectively reduced and improved.

[0008] Furthermore, utilizing the variable-volume suction and discharge device described above, at least two such devices are configured correspondingly, and the fluid inlet and outlet channels of the two devices are interconnected to form a closed active-passive drive circuit. During the operation of this circuit, when a difference arises between the driving force of the active suction and discharge device and the load resistance of the passive suction and discharge device, the expandable leaf chamber of the blade body automatically adjusts its volume under the action of the multiple differential forces until the driving force of the active suction and discharge device on the working fluid and the load resistance borne by the working fluid in the passive suction and discharge device reach equilibrium. At the same time, the suction and discharge volume of the working fluid per unit time between the active and passive suction and discharge devices approaches equality, and the ratio of the blade chamber capacity and the speed ratio between the active and passive suction and discharge devices are automatically adjusted to an inversely proportional balance during operation. Moreover, when the driving force or load resistance changes, the ratio of the blade chamber capacity and the speed ratio between the active and passive suction and discharge devices are automatically adjusted to achieve the above-mentioned operational balance, forming a smooth continuously variable drive. Summary of the Invention

[0009] The main objective of this invention is to provide a multi-bladed suction and discharge device with axially variable volume, based on the technical principles of the aforementioned prior art, and a variable speed drive system composed of the suction and discharge device. The main feature is that inside an impeller-type suction and discharge device, a multi-bladed rotor, a fixed wall member, a movable blade chamber sleeve, and another movable wall member are combined to form a multi-offset blade chamber area blade chamber body whose blade chamber volume can be varied along the axial direction of the multi-bladed rotor. The fixed wall member can be mounted on a frame, and the movable blade chamber sleeve can be mounted on the fixed wall member and, together with the movable wall member mounted on the multi-bladed rotor, form a movable blade chamber body that can synchronously displace along the axial direction of the multi-bladed rotor. When the movable blade chamber body moves closer to or further away from the fixed wall member, it causes the suction and discharge volume within the blade chamber to decrease or increase, thus enabling the suction and discharge device to have the function of axially variable blade chamber volume.

[0010] In the aforementioned multi-bladed suction and discharge device with axially variable volume, the multi-bladed rotor is provided with multiple blade grooves that can radially accommodate the blades. This allows the multiple blades to extend and retract between each blade groove and the inner wall of the blade chamber during operation. This enables the multiple blades to simultaneously perform suction and discharge transmission of the working fluid within their respective offset blade chamber areas. Furthermore, by utilizing the design of the multiple blade positions and the shape of the inner wall of the offset blade chamber area, the total amount of fluid sucked in and discharged by the suction and discharge device can be made approximately equal. This makes the application of the suction and discharge device in the power transmission of working fluids more stable and smooth.

[0011] According to the above structure, when the movable blade sleeve and the movable wall are forcibly pushed by an external force, the volume of the blade chamber in the suction and discharge device can be forcibly changed; or in a closed loop, when the pressure difference between the suction and discharge sides of the blade chamber body of the suction and discharge device is generated by compression and vacuum, a thrust or attraction force will be generated on the wall surface of the movable wall in the blade chamber body, so that the movable wall and the movable blade sleeve will be axially synchronously displaced relative to the fixed wall, and the volume of the blade chamber in the suction and discharge device will also change accordingly.

[0012] Another objective of this invention is to utilize the principle that the total amount of fluid drawn in and discharged by the suction and discharge device is approximately equal, and the mechanism that the volume of the blade chamber can be changed along the axial direction of the multi-bladed rotor. At least two suction and discharge devices are combined to form a primary and secondary drive transmission system, and the fluid suction and discharge passages of the primary and secondary suction and discharge devices are connected to form a closed drive circuit. Based on the principle that the driving force and load resistance will automatically reach a force balance, and that the volume of the blade chamber of the suction and discharge device is inversely proportional to the rotational speed, the rotational speed between the primary and secondary suction and discharge devices is at the optimal drive ratio, thereby achieving the most optimized continuously variable transmission drive effect.

[0065] The movable wall component 23 is provided with a movable wall surface 231 and a movable wall sleeve 232. The movable wall surface 231 is tightly attached to the end face 223 of the movable blade sleeve 22. A movable wall sleeve hole 233 is provided in the center of the movable wall surface 231.

The movable wall member 23 is fitted on the impeller 30 of the multi-blade rotor 3 with a movable wall sleeve hole 233, and the shaft of the multi-blade rotor 3 passes through the cover through hole 2361, so that the movable wall member 23 can slide along the axial direction of the multi-blade rotor 3.

[0067] The blade 31 has a blade tip edge 311 for contacting the inner wall of the blade chamber 220 (each offset blade chamber area 2203). A sealing strip 3111 can be provided or fitted on the blade tip edge 311 to increase the tightness between the blade tip edge 311 and the inner wall of the blade chamber 220. In the adopted embodiment, the blade 31 has an axially arranged connecting section 312. The connecting section 312 has a guide hole 3121 and a vertically connected radial transition section 313.

The other end of the sealing block guide post 37 can be connected to a rolling element (such as a pulley) 39 after passing through the guide hole 3121, so that the rolling element (such as a pulley) 39 can slide on the groove wall 2341 of the blade groove 234, thereby limiting the sealing block 38 to slide closely against the concave arc guide surface 381 of the blade top edge 311 and move radially up and down synchronously with the blade 31.

[0068] The first frame 4 has a cylindrical base 41, and a first fixing plate 42 is provided at one end of the base 41. The first fixing plate 42 is provided with a first shaft hole 421 and a fluid conveying hole 422 corresponding to the inner range of the base 41. In addition, a first positioning fluid conveying hole 423 and a second positioning fluid conveying hole 424 are respectively provided on the first fixing plate 42 corresponding to the outer range of the base 41. The base 41 is provided with a fixing chamber 411, a positioning part 412, and at least one opposing assembly part 413 (shown as a groove structure) formed on the inner surface of the base 41. A flow channel adapter 414 and a fixing wall sleeve 211 for assembling the fixing wall member 21 can be provided in the fixing chamber 411, providing the function of converting the rotating flow channel into a fixed flow channel interface and fixing the support blade chamber.

[0069] The second frame 40 is provided with a second fixed base plate 401. A hollow bushing 402 and a second shaft hole 403 are provided on the second fixed base plate 401. There is a bushing hole 404 at the junction of the second fixed base plate 401 and the hollow bushing 402. The bushing hole 404 and the second shaft hole 403 are adjacent concentric circles, allowing the second shaft end 34 of the multi-bladed rotor 3 to pass through the hollow bushing 402 and the bushing hole 404 and pivot on the second shaft hole 403.

[0070] The housing 80 has a chamber 81 inside, and a fluid passage 82 is provided on the housing 80 outside the chamber 81. A first through hole 821 and a second through hole 822 are provided at the junction of the fluid passage 82 and the two ends of the housing 80. The two ends of the housing 80 are mounted on the first fixing base plate 42 of the first frame 4 and the second fixing base plate 401 of the second frame 40, so that the first through hole 821 of the housing communicates with the first positioning fluid passage hole 423 of the first fixing base plate 42 of the first frame 4, and is assembled with the first frame 4 and the second frame 40 to form the outer housing of the suction and discharge device 100.

[0071] The flow channel adapter 414 is provided with an adapter shaft hole 4141 and a fluid transfer and delivery channel 4142, and is provided with an adapter positioning part 4143 and an adapter assembly part 4144 around its periphery. The flow channel adapter 414 is aligned with the positioning part 412 of the base 41 of the first frame 4 by the adapter positioning part 4143, and with the adapter assembly part 4144 aligned with the corresponding assembly part 413 of the base 41 (illustrated as the fitting structure of the groove and the rib), so that the flow channel adapter 414 is tightly fitted into the fixing sleeve 411 of the base 41 of the first frame 4. After assembly, the adapter shaft hole 4141 is connected to the first shaft hole 421 on the first fixed base plate 42, and the fluid transfer and delivery channel 4142 is connected to the fluid delivery hole 422 on the first fixed base plate 42.

[0072] After the flow channel adapter 414 is inserted into the fixing chamber 411 of the base 41 of the first frame 4, the fixing wall member 21 aligns the assembly portion 215 with the corresponding assembly portion 413 of the base 41 (illustrated as the fitting structure of the groove and the rib), inserting the fixing wall sleeve 211 into the fixing chamber 411 of the base 41, tightly engaging with the flow channel adapter 414; after the fixing wall member 21 is fixedly mounted on the base 41, the first shaft end 33 of the multi-bladed rotor 3 passes through the base hole 214 of the fixing wall sleeve 211 and the adapter shaft hole 4141 of the flow channel adapter 414, allowing the first shaft end 33 of the multi-bladed rotor 3 to pivot on the first shaft hole 421 of the first fixing base plate 42 of the first frame 4, and the protruding cylindrical column formed by the connecting cover 35 on the multi-bladed rotor 3 is embedded in the fixing wall end face 212 of the fixing wall member 21. The movable blade chamber sleeve 22 is encircled by the arc-shaped convex petals 2121 around the fixed wall end face 212 of the fixed wall member 21. The movable wall member 23 is fitted onto the impeller 30 of the multi-bladed rotor 3 with the movable wall sleeve hole 233 in the center of its movable wall surface 231. The blade chamber sleeve end face 223 of the movable blade chamber sleeve 22 is in close contact with the movable wall surface 231 of the movable wall member 23. The blade chamber volume of the blade chamber 220 of the movable blade chamber sleeve 22 is formed by the fixed wall end face 212, the inner wall of the blade chamber 220 of the blade chamber sleeve 221, the movable wall surface 231 and the impeller 30. When the movable blade chamber sleeve 22 and the movable wall member 23 move axially on the multi-bladed rotor 3 simultaneously, the volume of the blade chamber 220 will also change, resulting in the above combination having the characteristic of variable blade chamber volume.

[0073] The first shaft end 33 of the multi-bladed rotor 3 is pivotally mounted on the first frame 4, while the other second shaft end 34 passes through the movable wall member 23, the guide plate 24, the hollow bushing 402 and the bushing hole 404, and is pivotally mounted on the second shaft hole 403 of the second fixed base plate 401 of the second frame 40. The guide plate 24 has a hollow assembly sleeve 241 at its center, which is used to assemble on the hollow bushing 402 of the second fixed base plate 401. The guide plate 24 also has a guide portion 242 with an arc-shaped groove of different size corresponding to the arc-shaped concave inner wall of the blade chamber 220. This allows the guide portion 3131 of the blade 31 to rotate with the multi-bladed rotor 3 and roll tightly in the arc-shaped groove of the guide portion 242, so as to reduce the pressure on the inner wall of the blade chamber 220 caused by the centrifugal force generated by the rotation of the blade 31, and effectively reduce the frictional loss between the blade 31 and the inner wall of the blade chamber 220.

[0074] To maintain the enclosed space of the blade chamber 220, the blade chamber sleeve end face 223 of the movable blade chamber sleeve 22 and the movable wall surface 231 of the movable wall member 23 must remain in close contact. While the blade chamber sleeve end face 223 is fixed and does not rotate, the movable wall member 23 and the movable wall surface 231 rotate synchronously with the multi-bladed rotor 3. Therefore, a fixing member 5 can be used during assembly to restrict the combination of the movable blade chamber sleeve 22 and the movable wall member 23, ensuring that the blade chamber sleeve end face 223 and the movable wall surface 231 can operate while maintaining a close contact. The fixing member 5 consists of an annular restrictive body. The device comprises a ring-shaped limiting body 52 and a limiting body 51. The ring-shaped limiting body 51 can be fixedly sleeved between the leaf chamber sleeve 221 and the outer ring flange 222 of the movable leaf chamber sleeve 22. The limiting body 52 is provided with a limiting chamber 520 and an opening 5201. A limiting sleeve hole 521 and a plurality of fluid passage holes 522 are provided on the end face of the limiting chamber 520 away from the opening 5201. The limiting body 52 includes the movable wall member 23 in the limiting chamber 520 through its opening 5201, and allows the combined sleeve 241 of the guide plate 24 to pass through the limiting sleeve hole 521, and the edge of the opening 5201 forms a fixed connection with the ring-shaped limiting body 51.

[0075] Depend on Figures 1 to 4 As shown in the diagram, this embodiment is constructed using a combination of 5 offset blade chamber regions 2203 and 4 blades 31. The impeller 30 of the multi-bladed rotor 3 also has 4 blade slots 302, each blade slot 302 being evenly distributed at 90 degrees on the impeller 30. Two blades 31 positioned 180 degrees apart are considered complementary blade groups. In this complementary blade group, if one blade 31 slides towards the extended blade slot 302, the other blade 31 will slide towards the retracted blade slot 302, thus forming complementarity in the area of ​​their sweeping of the blade chamber wall. If the extended length of one blade 31 is nearly equal to the retracted length of the other blade 31, a synchronous connecting rod 316 can be used to connect the two blades 31 of the complementary blade group. This not only cancels out some of the centrifugal force but also forces complementary action and reduces errors. The 4 blades 31... The multi-bladed rotor 31 can form two complementary blade groups at 90 degrees to each other, so that the total sweeping area of ​​the four blades 31 at any unit angle of rotation approaches a constant. Since each blade slot 302 is provided with a first fluid output inlet 32a and a second fluid output inlet 32b across the blades 31, which are responsible for the fluid outlet or inlet respectively, and since the total sweeping area of ​​the four blades 31 at any unit angle of rotation of the multi-bladed rotor 3 approaches a constant, the total fluid volume entering and exiting all the first fluid output inlets 32a will also approach equal to the total fluid volume entering and exiting all the second fluid output inlets 32b. This configuration makes the total fluid volume entering and exiting the suction and discharge devices 100 nearly equal, which allows the suction and discharge devices 100 to operate and drive more smoothly in fluid-driven applications.

[0076] In the above-described embodiment design, the number of blades 31 is less than or equal to the number of offset blade chamber regions 2203, so as to avoid the situation where the first fluid output inlet 32a on one side of the blade 31 and the second fluid output inlet 32b of the adjacent blade 31 appear in the same offset blade chamber region 2203 at the same time, causing the suction and discharge fluids to communicate and reduce the driving efficiency.

[0077] As the multi-bladed rotor 3 rotates, the offset blade chamber region 2203, into which the blades 31 enter, is divided into suction and discharge sides by the blades 31. The fluid on both sides of the suction and discharge device communicates with the outside of the device through the first fluid output inlet 32a and the second fluid output inlet 32b. The first fluid output inlet 32a is connected to the first fluid channel 33a and communicates with the outside through the first shaft hole 421 of the first frame 4. The second fluid output inlet 32b is connected to the second fluid channel 33b, and after merging in the reserved space at the junction of the flow channel adapter 414 and the fixed wall member 21, it flows through the fluid transfer and conveying channel 414. 2. The fluid conveying hole 422 on the first fixed base plate 42 communicates with the outside. The blade 31 slides radially back and forth in the blade groove 302 as the multi-blade rotor 3 rotates, so that part of the blade tip edge 311 keeps in contact with the inner wall of the offset blade chamber area 2203, while the other part of the blade 31 slides back and forth in the blade groove 234 of the movable wall member 23. When the movable blade chamber sleeve 22 and the movable wall member 23 move synchronously to make the volume of the blade chamber 220 smaller, more blades 31 will be in the blade groove 234, and vice versa. Therefore, the movable wall member 23 must rotate synchronously with the multi-blade rotor 3.

[0078] The suction and discharge device 100 can forcefully push the fixing member 5 to cause the movable blade chamber sleeve 22 and the movable wall member 23 to simultaneously generate axial displacement, thereby changing the volume of the blade chamber 220; or the fixing member 5 can be configured to be tightly sealed to the inner wall of the shell chamber 81 of the housing 80, and the shell chamber 81 can be filled with fluid, so that the fluid in the shell chamber 81 is divided into two sides by the fixing member 5. When the fixing member 5 moves, the fluid on one side of the fixing member 5 will enter and exit through the second through hole 822 of the housing, through the fluid passage 82 and the first through hole 821 of the housing, and through the first positioning fluid passage hole 423 of the first fixed base plate 42 of the first frame 4; the fluid on the other side of the fixing member 5 will enter and exit through the second positioning fluid passage hole 424 of the first fixed base plate 42 of the first frame 4; if the amount of fluid entering and exiting on both sides of the fixing member 5 in the shell chamber 81 is controlled, the fixing member 5 can also be pushed to achieve the effect of changing the volume of the blade chamber 220.

[0079] The aforementioned component assembly incorporates several features designed to enhance sealing. At the junction of the inner wall of the movable blade chamber 220 and the end face 223 of the blade chamber sleeve 22, at the junction of the blade groove 234 of the movable wall member 23 and the movable wall surface 231, and at the junction of the blade tip edge 311 of the blade 31 and the inner wall of the blade chamber 220, a sealing block 38 is provided to fill the gaps between these junctions. Each blade groove 234 of the movable wall member 23 has a sealing groove 235 near the movable wall surface 231, and a sealing clip 382 can be inserted into the sealing groove 235, with the sealing clip 382 laterally clamping against the blade groove. On both sides of the blade 31 of the groove 234, the gap between the blade 31 and the groove 234 can be filled; at the junction of the movable wall sleeve hole 233 of the movable wall member 23 and the impeller 30 of the multi-blade rotor 3, an impeller sealing ring groove 303 is provided on the impeller 30 for the insertion of a sealing ring; at the junction of the first shaft end 33 of the multi-blade rotor 3 and the base hole 214 of the fixed wall member 21, a fixed sealing ring groove 331 is provided on the first shaft end 33 for the insertion of a sealing ring; at the junction of the first shaft end 33 of the multi-blade rotor 3 and the adapter shaft hole 4141 of the flow channel adapter 414, an adapter sealing ring groove 332 is provided on the first shaft end 33 for the insertion of a sealing ring.

[0080] Please see Figure 3B and Figure 5 ,exist Figure 5On the left is an active device 101 using the aforementioned suction and discharge device 100, and on the right is a passive device 102 using the aforementioned suction and discharge device 100. The suction and discharge channels of the active device 101 and the passive device 102 are interconnected to form a closed loop of active and passive drive. The first fluid channel 33a (discharge side) of the active device 101 is connected to the fluid delivery port 422 of the passive device 102 via the first shaft hole 421, and then connected to the second fluid channel 33b of the passive device 102. (Suction side); The second fluid channel 33b (suction side) of the active device 101 is connected to the first shaft hole 421 of the passive device 102 via the fluid delivery hole 422, and then connected to the first fluid channel 33a (discharge side) of the passive device 102, forming a closed loop of fluid circulation; If the rotation direction of the multi-bladed rotor 3 of the active device 101 is such that the blades 31 squeeze the fluid toward the first fluid output inlet 32a in the offset blade chamber region 2203, then the active device 101... The working fluid is transported from the first fluid output inlet 32a (discharge side), through the first fluid channel 33a, and then through the first shaft hole 421 to the fluid delivery hole 422 of the passive device 102. It then passes through the second fluid channel 33b and enters the offset blade chamber region 2203 of the passive device 102 from the second fluid output inlet 32b (suction side). Within the offset blade chamber region 2203 of the passive device 102, the working fluid is swept alternately by the blades 31 and then exits from the first fluid output inlet of the passive device 102. The fluid flows from the outlet 32a (discharge side) through the first fluid channel 33a, then through the first shaft hole 421 to the fluid delivery hole 422 of the active device 101, through the second fluid channel 33b, and then through the second fluid output inlet 32b (suction side) into the offset blade chamber region 2203 of the active device 101, completing a closed loop of fluid circulation. If the rotation direction of the multi-bladed rotor 3 of the active device 101 is opposite to the above, the circulation path and suction / discharge side of the working fluid become opposite, so it will not be described again.

[0081] The aforementioned active and passive devices 101 and 102 are composed of suction and discharge devices 100 of the same size, and the two form a closed fluid circulation drive loop, so that the total volume of the blade chambers in the active and passive devices 101 and 102 remains constant. When the movable blade chamber sleeve 22 and movable wall member 23 of one of the active and passive devices 101 and 102 are displaced along the axial direction of the multi-bladed rotor 3 to change the blade chamber volume, the movable blade chamber sleeve 22 and movable wall member of the other device of the active and passive devices 101 and 102 will also change. 23 will also generate synchronous equidistant axial displacement, but the displacements of the movable blade chamber sleeve 22 and the movable wall member 23 relative to the fixed wall member 21 are in opposite directions. One device reduces the blade chamber volume, and the other device increases the blade chamber volume. The changes in blade chamber volume between the active and passive devices 101 and 102 are complementary. If the multi-bladed rotor 3 and blade chamber body 2 between the active and passive devices 101 and 102 constitute the components of the blade chamber 220, they are configured with corresponding mirror images based on the fixed wall member 21 (e.g., Figure 5 The configuration allows the blade chambers 220, composed of the active and passive devices 101 and 102, to be symmetrically positioned on both sides of the fixed wall member 21. This ensures that the movable blade chamber sleeves 22 and the movable wall member 23 between the active and passive devices 101 and 102 will form a synchronous, equidistant displacement relationship. To avoid errors caused by issues such as the sealing of the blade chambers 220, a synchronous displacement connector 9 can be used to connect the movable blade chamber sleeves 22 or the fixed member 5 between the active and passive devices 101 and 102. This ensures that when the volume of the blade chambers changes between the active and passive devices 101 and 102, they will move synchronously and equidistantly.

[0082] In addition to the aforementioned active and passive devices 101 and 102 being connected by a synchronous displacement connector 9 in a mirror configuration to ensure that they will move synchronously and in the same direction at equal distances, the interior between the outer surface of the blade chamber 2 of the active and passive devices 101 and 102 and the housing 80 can be filled with liquid. This liquid is then divided into two sides radially (e.g., by the fixing member 5) along the intersection of the movable blade chamber sleeve 22 and the movable wall member 23, with a liquid flow channel separating the same side of the active and passive devices 101 and 102 near the movable blade chamber sleeve 22. The two devices are connected, and the same side of the movable wall member 23 is also connected, so that the liquid inside the two same sides of the main and passive devices 101 and 102 can flow synchronously and complementaryly between the main and passive devices 101 and 102. The movable blade chamber sleeve 22 and movable wall member 23 of the main and passive devices 101 and 102 are forced to undergo synchronous equidistant displacement due to the pressure of the filled liquid, so as to reflect the synchronous change of the blade chamber volume of the main and passive devices 101 and 102 in a complementary relationship of increase and decrease.

[0083] In the closed loop of the aforementioned active and passive fluid circulation, if the load resistance of the passive device 102 increases, the working fluid output from the discharge side of the active device 101 to the suction side of the passive device 102 will continuously exert pressure on the entire passage of both the discharge side of the active device 101 and the suction side of the passive device 102. This results in a vacuum suction force being formed on the suction side of the active device 101 due to a decrease in the working fluid flowing back from the discharge side of the passive device 102. The pressure difference between suction and compression generated on the suction and discharge sides of the active device 101 and passive device 102 generates suction and thrust on the movable wall members 23 of the active and passive devices 101 and 102, based on the principle of force balance. When the speed of rotation is reduced, the movable wall member 23 of the active device 101 is attracted towards the fixed wall member 21, and the movable wall member 23 of the passive device 102 is pushed away from the fixed wall member 21. This causes the blade chamber volume of the active device 101 to decrease and the blade chamber volume of the passive device 102 to increase. Since the speed of rotation is inversely proportional to the volume, the movable wall members 23 of the active and passive devices 101 and 102 are automatically pushed to a position similar to downshifting. If the load resistance of the passive device 102 decreases, the opposite action occurs, causing the movable wall members 23 of the active and passive devices 101 and 102 to be automatically pushed to a position similar to upshifting.

[0084] In the structure of the suction and discharge device 100 described above, the blade tip edge 311 of the blade 31 will continuously sweep against the inner wall of the blade chamber 220 as the multi-bladed rotor 3 rotates. In addition, the centrifugal force generated by the rotation of the blade 31 itself makes the sliding friction of the blade 31 pressing against the inner wall of the blade chamber 220 extremely obvious. In order to reduce the centrifugal force generated by the blade 31 itself from increasing the contact sliding friction loss on the inner wall of the blade chamber 220, the centrifugal force generated by the blade 31 can be designed in the structural assembly to transfer the centrifugal force generated by the blade 31 to other rolling components such as rolling wheels or bearings that roll in contact with at least one part of the suction and discharge device 100, so that the sliding friction loss is changed to rolling friction loss, or the area of ​​sliding friction is reduced, so as to effectively reduce the performance loss caused by friction. Several examples are listed below for specific implementation.

[0085] In this invention Figure 1 and Figure 2A The main purpose of the linkage between the guide plate 24 and the blade 31 is to change the centrifugal force of the blade 31, which was originally applied to the inner wall of the blade chamber 220, to the rolling force of the guide part 3131 of the blade 31 on the guide rail of the guide part 242 of the guide plate 24, thereby reducing frictional loss.

[0086] Figure 6A and Figure 6BThe movable leaf chamber sleeve 22 disclosed herein is provided with an outer guide rail groove 224, and the sealing block 38 is provided with an outer guide rail shaft 383, on which an outer guide rail roller 384 can be fitted; after assembly, the outer guide rail roller 384 can roll in the outer guide rail groove 224 of the leaf chamber, and its function is as follows: Figure 1 , Figure 2A The guide plate 24 on the upper part is linked with the blade 31. It changes the sliding friction pressure caused by the centrifugal force of the blade 31 on the inner wall of the blade chamber 220 to rolling friction pressure, thereby reducing friction loss. At the same time, a guide groove end face 2241 is provided in the direction of the guide groove 224 outside the blade chamber towards the movable wall member 23, so that the movable wall surface 231 of the movable wall member 23 and the sealing block 38 are tightly pressed against the guide groove end face 2241 to form a seal.

[0087] exist Figure 7 , Figure 8 As shown, the inner ring tooth circular guide disk 341 is provided with an inner ring gear 3411, which, like the guide disk 24, is fixedly mounted on the hollow shaft sleeve 402; multiple guide rail gears 342 are mounted on the guide rail synchronous connecting frame 343, which is fixedly mounted on the second shaft end 34. As the multi-bladed rotor 3 rotates, the multiple guide rail gears 342 mesh and roll on the inner ring gear 3411 of the inner ring tooth circular guide disk 341.

[0088] exist Figure 7 As shown, the guide rail connecting rod 314 is provided with a cam shaft seat hole 3141 and a blade insert seat guide groove 3142, and the guide rail gear 342 has a cam shaft 3421. A cam shaft bearing 3422 can be fitted on the cam shaft 3421, and the cam shaft seat hole 3141 of the guide rail connecting rod 314 can be fitted on the cam shaft bearing 3422. The radial transition section 313 is provided with a connecting rod insert 3132, and the blade insert seat guide groove 3142 of the guide rail connecting rod 314 is fitted on the connecting rod insert 3132, so that the movement of the blade 31 is similar to the reciprocating operation of the piston of an engine. The centrifugal force applied by the blade 31 is converted into the force on the cam shaft bearing 3422 and the blade insert seat guide groove 3142 assembled on the guide rail connecting rod 314, reducing the sliding friction of the blade 31 on the inner wall of the blade chamber 220 and converting it into the rolling friction of the aforementioned bearing.

[0089] exist Figure 8 As shown, the connecting section 312 of the blade 31 is connected to a radial connecting rod 315, one end of which is connected to a slide rail guide rod 3151; the guide rail gear 342 originally had Figure 7At the position of the convex shaft 3421, there is a hole for installing a ring bearing 3423, and a ring 3424 can be assembled on the ring bearing 3423. Then, the ring 3424 is fitted onto the slide rail guide rod 3151 of the radial connecting rod 315. When the ring 3424 moves with the blade 31, it will slide back and forth on the slide rail guide rod 3151. This changes the centrifugal force that was originally applied by the blade 31 to the inner wall of the blade chamber 220 by sliding friction. Instead, the force is borne by the ring bearing 3423 and the ring 3424 on the slide rail guide rod 3151. This changes some of the sliding friction to rolling friction, and also reduces the friction area of ​​the sliding friction part, which can effectively reduce friction loss.

[0090] In summary, the suction and discharge device 100 of the present invention has the characteristics that its movable blade chamber sleeve 22 and movable wall member 23 can change the volume of the blade chamber by axial displacement along the multi-bladed rotor 3, and that the total amount of fluid sucked in and the total amount of fluid discharged are approximately equal. Utilizing the aforementioned characteristics of the suction and discharge device 100, a continuously variable transmission drive system can be formed, which can automatically adjust the speed ratio between the drive devices by applying the principle of force balance without the need for external force intervention, thus achieving the optimal gear strategy.
