Description of the invention (彳) / Description of the invention: The present invention relates to a motor and / or a power device for a pressure fluid pump that operates as a pressure flow system. It includes a cylindrical space, a piston rotating in the stern pillar space, and a channel through which pressure fluid flows into the cylindrical space. Various power units are known as pressure fluid operated configurations, such as pressure fluid operated motors and pressure fluid pumps. There are also many pressure fluid operated motors', such as piston motors, screw motors, gear motors and windmill motors. There are also many types of pressure fluid pumps, such as piston pumps, screw pumps, gear pumps and windmill pumps. The same power unit usually has the functions of a motor and a pump, for example, the same hydraulic motor and hydraulic pump can be used in the same device. The structure and manufacturing method of the power unit containing the piston is usually very complicated, so it contains gaskets and some parts that are easy to wear. Therefore, the manufacturing cost is high, and the maintenance service also greatly increases the cost of operation. On the other hand, screw arrangements are also very expensive and difficult to manufacture. Windmill motors, gear motors, and windmill pumps and gear pumps have cheaper manufacturing costs, but overall, windmill-type power units have poor efficiency and are extremely inaccurate in operation. Another problem with the conventional technology is that when it is used to operate a driver, it is often difficult to accurately guide the driver to a predetermined position, and to control some alternate work operations, such as the need for additional and control systems This makes conventional technology difficult and expensive. It is an object of the present invention to provide a power unit which is a pressure fluid operating configuration which can be easily modified, which can produce an accurate operation in the same way. The power device of the present invention is characterized in that the paper size is applicable to the Chinese National Standard (CNS) A4 specification (210X297 mm) (Please read the precautions on the back before filling this page) -----.! --- 1 ^ ----- ^ -------- ^ 1 A7 B7 V. Description of the Invention (2) The cylindrical space is ring-shaped; the power unit includes at least two pistons that rotate with each other, and the piston is cut off from the cylindrical space. The size and shape of the surface are almost the same; at least one piston is rotated around the axis of the cylindrical space, so that the piston can rotate in the circumferential direction of the cylindrical space; the power unit may further include a transmission shaft that rotates around the piston shaft in the cylindrical space. The locking member that can lock at least one piston 'makes it impossible to rotate or slow down relative to the axis of the cylindrical space, so at least one set of pistons and transmission shafts that accompany its rotation can instantly oppose the cylindrical space and around its axis. Rotation, and channels that direct pressure fluid into and out of the space between the pistons. Economy. Printed by the Consumer Standards Cooperative of the Central Bureau of Standards (please read the precautions on the back before filling this page) The purpose of the present invention is to have a circular, closed cylindrical space around a rotation axis' and at least two rotations around the axis. With the piston having the shape of the annular cross section, the way of rotating the piston around the shaft is to prevent at least one piston from rotating relative to the shaft or slow down its operation at the same time. Another aspect of the present invention is directed to a passage containing a portion of a cylindrical space between which the pressure fluid can flow into and out of between the two pistons. When pressure fluid is injected into a space between the two pistons, one of the pistons does not rotate or slows down. The pressure fluid will drive the other pistons, and the pistons will rotate the shaft directly or indirectly connected to the cylindrical space. Similarly, when a shaft rotates, it will simultaneously drive the piston connected to it, and when a piston does not rotate or its operation slows down, the shaft will drive the pressure fluid out of the space between the pistons. An advantage of the present invention is that pistons that do not rotate or rotate about the axis of the cylindrical space can be used. The pistons are arranged one after the other in the circular cylindrical space, so that continuous rotary motion can be generated parallel to the cylindrical space. If one or more pistons do not rotate at the same time, a predetermined deflection angle can be provided. This configuration is applicable to the Chinese National Standard (CNS) A4 specification (210 / 2.97 mm.) As the paper size. -5- Ministry of Economy A7 B7 printed by the Consumer Standards Cooperative of the Central Bureau of Standards 5. Description of Invention (3) — Stepping motor. Another advantage of the present invention is that the piston and the outer surface of the cylindrical space have a tight enough space, so there is no need for any additional gaskets, so it can operate efficiently, and contains almost wear-free parts. Therefore, there are various improved configurations, which are not only economical to manufacture, but also easy to operate. The present invention will be described in more detail with reference to the accompanying drawings, in which FIGS. 1 a to 1 c are perspective views of an embodiment modified in accordance with the operating principle of the power plant of the present invention, and FIG. 2 is a view of FIG. 1.

Figures 1a to 1C are general views of the basic structure of the power plant of the present invention. The power plant shown in the figure comprises a circular, closed cylindrical space 1. In the center of the cylindrical space 1, there is an axis' concentric with the cylindrical space, and the shaft is composed of two concentric rotary transmission shafts 2 and 3. The cylindrical space may further include two pistons 4 and 5 having a sectional shape of the cylindrical space, and the two are fixed to the transmission shafts 2 and 3 in a non-rotatable manner, respectively. Therefore, except for the case where the two pistons are in contact when rotating, the transmission shaft 2 and the piston 4 can rotate relative to the cylindrical space 1 regardless of the transmission shaft 3 and the piston 5, and vice versa. Theoretically, the transmission shafts 2 and 3 extend beyond the stern column space 1. In fact, '----------- ----- ~ -__ are the two ends required to form a cylindrical space. Flange, so the power can be transmitted to the power unit through the paper size of the shaft according to the Chinese National Standard (CNS) A4 specification (2 丨 〇 乂 297 mm) A7 B7 5. Invention description (5) and the piston on the shaft The power generated by the pressure or pressure fluid acting on the piston can be transmitted from the power device. For simplicity, the end flange is not shown in Figures 1a to 1c. A passage 6 passes through the transmission shaft 2. In the figure, there is a passage opening 6 a on the right side of the piston 4, that is, the part marked V 1 in the cylindrical space 1. Similarly, the end of the transmission shaft 3 (not shown) has a channel flowing at the plane of the piston 5 opposite to the plane of the piston 4 so that the plane communicates with the portion of the annular cylindrical space 1 marked V2. Printed by the Consumer Cooperatives of the Central Standards Bureau of the Ministry of Economic Affairs (please read the precautions on the back before filling in this page) When the power unit is used as a hydraulic motor, for example, the piston 4 is locked to prevent it from rotating, and then the pressure The fluid is injected into the portion of the cylindrical space V 1 between the pistons 4 and 5 via the passage 6. When the passage through the piston 5 and through the transmission shaft 3 is opened at the same time, the pressure of the pressure fluid in the space V 1 will cause the piston to move in the direction of the arrow A in the middle, and at the same time, the pressure fluid will pass from the space through the passage of the piston 5 V 2 flows out. When the piston 5 moves to the position as shown in Fig. 1b or even comes into contact with the piston 4, the piston 5 will be blocked so that it cannot rotate and pressure fluid will flow in from other channels. As shown in FIG. 1. C, the pressure fluid passes through the transmission shaft 3 and flows into the space V 2 between the pistons 5 and 4 through the opening 7 a of the piston 5. At this time, the pressure fluid will push the piston 4 to advance in the circular cylindrical space, so the transmission shaft 2 is rotated at the same time, and the pressure fluid flows into the pressure fluid passage 6 from the opening 6 a on the transmission shaft 2 of the piston 4 and follows Which flows out. The piston is rotated in the cylindrical space 1 by the alternating feeding of pressure fluid and the locking of the piston. This rotation can be recovered 'at the ends of the drive shafts 2 and 3' and transmitted via it to the device to be operated. Therefore, the shaft and the locking member in the separation body are properly scaled to the Chinese national standard (CNS) A4 (210 X 297 mm). ΚΊ _________ Β7 _ 5. Description of the invention (6) The ground connection can surround the cylindrical space 1 The casing 8 rotates, so that the generated power can be recovered from the rotation. Even if one of the pistons is not completely locked, a rotary motion can be generated, which can be slowed down by brake pads or other speed-reducing devices. The above functions can also be run in reverse, in which the drive shaft 2 or 3 rotates mechanically, and the piston above it also rotates. At this time, the 'piston pushes the pressure fluid out of the pressure fluid channel, and the non-pressure fluid flows from the other pressure fluid channel into another space, so the power unit of the present invention can also be used as a pump. Printed by the Consumers' Cooperative of the Central Standards Bureau of the Ministry of Economic Affairs (please read the precautions on the back before filling out this page) Figure 2 is an exploded view of an embodiment of the power plant of the present invention. As shown in the figure, the transmission shafts 2, 3 and the pistons 4, 5 are connected in a square type so that they can be placed on one of the pistons' shafts. In order to maintain the direction and position of the transmission shaft regardless of the acting power, a support shaft 9 needs to be placed between the two, and the shaft is installed at both ends of the transmission shafts 2 and 3 in an appropriate direction. This installation can be modified using plain bearings or other known bearings. The figure may further include an end flange 10, which can be used to form a cylindrical space 1 around the drive shafts 2, 3 and inside the housing 8. The figure also includes one-way clutches 11 and Γ 2 mounted on both ends of the drive shafts 2 and 3 and located outside the end flange 10. The one-way clutch includes an inner circumference, an outer circumference, and a locking member therebetween. The function of the one-way clutch is to allow the inner circumference and the outer circumference to rotate freely in one direction with each other, but the reverse rotation of the two can be avoided by the locking member. Such one-way clutches and their structures are well known and can be obtained everywhere, so the detailed structure is not described herein. In the embodiment of the present invention, the one-way clutches 11 and 12 are based on the paper size of the key and apply the Chinese National Standard (CNS) A4 specification (210X297 mm) -9- A7 B7 Employees' Cooperatives of the China Standards Bureau of the Ministry of Economic Affairs Printed 5. Description of the invention () 14 is inserted into the key groove 13 shown in the figure, so that the inner circumference of the clutch is fixed on the drive shafts 2 and 3, respectively. In addition, the free rotation directions of the one-way clutches 11 and 12 on the same axis are opposite. In addition, the free rotation direction of the one-way clutch 11 adjacent to the end flange 10 on the rain transmission shafts 2 and 3 is parallel to the direction of rotation of the one-way clutch indicated by the dotted arrow in the figure. Next, the outer circumference of the one-way clutch 11 is placed on the end flange .10 without rotation, and the outer circumference of the outer one-way clutch 12 is placed on the separated fastener 15 without rotation. Theoretically, the fastener 15 can be a part of the whole or can be fixed on the same object or table so that the two do not rotate with each other. In some embodiments, the drive shaft may be connected to a gear or the like to rotate a device or a shaft. There is also a coupling 16 for pressure fluid in the figure, and the pressure fluid can be injected into or out of the cylindrical space 1 through the channels 6 and 7. In the figure, there is another section of the piston and the shaft along the line A-A to show how the channel 6 communicates with the opening 6 a so that the pressure fluid is injected or discharged from the cylindrical space 1. FIG. 3 is a partial cross-sectional view of the embodiment of the present invention shown in FIG. 2, and the figure is configured in an assembled state. As shown in the figure, the housing 8 and the end plate 10 form a closed cylinder, and the drive shafts 2 and 3 surround a circular cylindrical space. The one-way clutch 1 1, 12 is fixed to the transmission shafts 2, 3 by fixing the one-way clutch 12 on the coupler 15, and the one-way clutch Γ 1 is fixed on the end flange 10, as shown in the figure. As shown. There is a separate spacer ring 17 between the two one-way clutches to keep the two at a proper distance, but this structure can also be improved. In the figure, there is also a key 1 4 which can connect the drive shaft 3 and the one-way clutch 1 1, 1 2. And one end of the drive shaft 2 is also opposite (please read the precautions on the back before filling this page), τ This paper size applies the Chinese National Standard (CNS) A4 specification (210X297 mm) -10- A7 B7 Central Standard of the Ministry of Economic Affairs Bureau employee consumer cooperative printed five, invention description (8) should be the key, but it is not shown in the figure. As shown, the piston 5 has the same shape and size as the cylindrical space 1. Therefore, the entire cylindrical space 1 can be closed. In this embodiment, the piston 5 is fixed to the transmission shaft 3 by a fixing bolt 18 extending from the surface of the piston 5 near the flange 8 to the transmission shaft 3. One channel 7 passes through the transmission shaft 3, and the other channel passes through the opening 7a of the piston 5 and extends along the radial direction of the channel 7 to form a uniform channel for the pressure fluid. Since the fixing bolt 18 is located at the center of the piston 5, the outer surfaces of both sides of the bolt hole of the piston 5 can seal the piston inside the casing 8. Piston 4 (not shown) is also connected to shaft 2 in the same way and has the same function. In addition to bolt fixing, the piston can also be fixed to the shaft by other known fixing methods, and the space between different surfaces is usually small or can be sealed with a suitable gasket. In this embodiment, feeding the pressure fluid into the cylindrical space 1 between the pistons 4, 5 will cause a piston to be locked so that it cannot rotate by the one-way clutch 11 at the end flange 10, while the other piston is opposed Due to coupling 15 blocking. As a result, the entire structure, that is, the housing, the end flange and one of the pistons can be rotated relative to the coupler 15, so that the rotating power can be transmitted to the appropriate driver through the housing 8 and the end flange 10. Similarly, when the pressure fluid is fed into other spaces between the pistons, the pistons are connected in other ways, that is, the piston fixed to the front flange first will be fixed to the fastener with the side edge, and the other piston It is connected to the end flange instead of the fastener. Due to the injection of the pressure fluid, the housing 8, the end flange 10 and one of the pistons will rotate in the same direction relative to the fastener 15. In this embodiment, the one-way clutches 11 and 12 act like locking members, so that the shaft locking cannot be relative to the cylindrical space.

In this embodiment, the piston 4 is fixed to the housing 8, and only the piston 5 can rotate around the shaft. The numbers in the figure have the same effect as the previous figure to avoid confusion. In this embodiment, the piston 5 is fixed to the casing 8 so as to form a single body, and only the piston 4 rotates around the shaft 2. When the pressurized fluid is fed into the space V1 through the passage 6, the manner in which the piston 4 rotates around the shaft and is transmitted to the one-way clutch is the same as that described in Figs. When the pressure. Fluid is injected into the space v 2 through the passage of the shaft 3, the piston 5 will rotate around the shaft and away from the piston 4, while also rotating the casing. As described in the principle above, the shaft 3 connected to the housing and the end flange will transmit this rotational movement. FIG. 5 is an exploded view of the embodiment shown in FIG. 4. In this embodiment, the power unit includes an auxiliary shaft 19 for rotating the entire power unit. The auxiliary shaft 19 passes through the shafts 2 and 3, so it can rotate around the auxiliary shaft 19. Both ends of the auxiliary shaft 19 have internal channels 6 and 7 ', but only the channel 7 is shown in the figure. The pressure fluid can flow through the openings 6 a '7 a on both sides of the piston 4 and the channel extending in the shaft 2. The channel is almost parallel to the radius. ° The auxiliary shaft 19 at both ends of the channel has a groove 2 for pressure fluid. 3 a ° This groove corresponds to the channel 2 of the shaft 2 of the piston 4 so that pressure fluid can be fed into either side of the piston via the channels 7 and 6.

Description of the invention (10) The power is transmitted from the shafts 2 and 3 to the auxiliary flange 20, and the way is that the auxiliary flange and the auxiliary housing 20 surround the piston as a whole. 4. '5 rotations' while the housing 8 rotates around the auxiliary shaft 19 and relative to the fastener 15. FIG. 6 is a schematic, partial cross-sectional view of the embodiment of the present invention viewed from the axial direction of FIG. 5. As shown in the figure, the auxiliary casing 8 and the auxiliary flange form a casing that surrounds the casing 8 and the end flange 10. The piston 4 is mounted on a shaft 2 which rotates around an auxiliary shaft 19. The channel 6 extends from the pressure fluid groove 6 a of the auxiliary shaft 19 to the axial channel toward the channel opening 6 a, whereby the pressure fluid can flow into the groove 2 a along the channel 6 and from the opening 6 a into the cylindrical space. 1 within the V 1 part. Similarly, the other side of the piston 4 has an opening 7a connected to the pressure fluid groove 3a, so that the pressure fluid flows from the opening 7a into the V of the cylindrical space 1 through the channel 7 on the other end of the auxiliary shaft 19 Within 2 sections. Therefore, the piston alternately rotates around the auxiliary shaft 10 so that the cylinder composed of the auxiliary flange 20 and the auxiliary housing 21 can rotate in a predetermined direction. In addition to the separate auxiliary housing 21 and auxiliary flange 20, one of the auxiliary flanges and the auxiliary housing may be formed as an integral part. It is also possible to use two semi-cylindrical cylinders, both of which contain an auxiliary flange 20 and a shell-like portion. The combination of two such shell-like portions makes it a monolithic cylinder. In addition, in addition to the enclosed auxiliary housing 21, the cylinder can also be separated by one or more sets of fasteners, and the fasteners can be internally connected to each auxiliary flange 20. Figures 7a and 7b are general perspective views of some embodiments of the invention. As can be seen from the configuration of the pistons in the figure, the same power unit contains some pistons that are symmetrical to, for example, a rotating shaft. In both figures there are two pairs of pistons. Each pair of pistons has a symmetrical axis of rotation for balance. Figure 7a shows the paper sizes shown in Figures 1 to 3 as applicable to the Chinese National Standard (CNS) A4 specification (210X297 mm) ~~ " (Please read the precautions on the back before filling this page) i7 A7 B7 Printed by the Consumer Cooperatives of the Central Bureau of Standards of the Ministry of Economic Affairs 5. Application of the embodiment of the invention description (u), in which all the pistons are rotated relative to the shell of the cylindrical space, and Figure 7b is according to Figure 4 to Figure. In the application of the embodiment shown in FIG. 6, half of the pistons are rotated around an independent axis and the other half of the pistons are non-rotatably disposed on the casing 8 of the cylindrical space. According to this principle, the pistons can be configured as a group containing multiple pistons. The most obvious embodiment of this situation is to arrange the two groups of pistons with symmetrical rotation axes, as shown in Figs. 7a and 7b. When using multiple pistons, a powerful motor or pump with precise dimensions and functions can be provided, and it can easily be regarded as a step motor or a feed pump. In either case, the manner in which the pressurized fluid is fed into the space between the pistons can be modified in the manner described above or in the same manner. The invention can be modified in various ways. It is not necessary to use two separate end flanges in the device: one of the flanges and the housing can also form an integral part. The axial section of the piston is preferably such that its side is parallel to the radial direction of the rotary shaft, but other types of sections may be used. The size of the pistons can also be varied 〇 In addition to two pistons, three or more pistons can be used if required. However, in these embodiments, it is sometimes necessary to place a thousand-shaft between the mutual pistons to transmit rotary motion. Similarly, if there are multiple sets of pistons fixed to the same axis at the same time, the transmitted power will be doubled due to the increase in the number of pistons. If the number of pistons is even, it is best to be divided into two symmetrical groups relative to the rotation axis . In addition to one-way clutches, other types of locks can also be used, such as different clutches, brakes or latching mechanisms. Similarly, different timers can be used to adjust the flow of the pressure fluid being fed to make it flat (please listen to the notes on the back before filling in this page) Order 'ΛΤ.

Description of the invention (12) Smooth movement and more accurate stepping. In these embodiments, a separate control may be used to operate the latch so that the power unit as a motor or pump can be operated in a predetermined manner. When a one-way clutch is used, it can be used immediately as a bearing for the piston, but when other types of locks are used, this mounting method can be improved in different ways. Sometimes even if a plain bearing is sufficient to improve it, other types of conventional bearings can still be mounted on the piston shaft. The auxiliary shaft used in FIGS. 4 to 6 can also be applied to the embodiments shown in FIGS. 1 to 3. ‘In the power plant of the present invention, various gases or gas mixtures, such as air, or various pressure fluids, such as oil, water, etc. can be used as the pressure fluid. Channels that direct pressure fluid into or out of the space between the pistons can pass through the shaft, through the shaft and piston, through the flanges that form the walls of the cylindrical space, or through known methods such as housings. The power unit of the present invention can be used as a feed pump or a stepping motor because it can limit the operation from one position to another. In order to achieve the predetermined operating effect, various transmission mechanisms can be used to avoid shaft rotation, or multi-pistons can be used to limit its operation. Because it can provide a certain degree of deflection angle, the operation amount or pressure fluid can be adjusted. Of traffic. In addition to the cylinder shown in Fig. 5, a separate second shaft or other known transmission mechanism can naturally be used to transmit power from the power unit.
