Abstract
A vane-type fluid transmission device includes a rotor eccentrically located in the room of a stator and the outer periphery of the rotor is tangent to the inner periphery of the room. At least one blade is pivotably connected to stator and movably inserted in at least one slot of the rotor. The distal end of the at least one blade is in contact with the inner periphery of the room so as to form a space for receiving fluid between the outer periphery of the rotor and the inner periphery of the room. The contact between the at least one blade and the inner periphery of the room increases the efficiency for transmitting fluid which enters into the stator from an inlet and leaves from the stator from an outlet.
Description
VANE-TYPE FLUID TRANSMISSION DEVICE
FIELD OF THE INVENTION
The present invention relates to a fluid transmission device, and more particularly, to a vane-type fluid transmission device.
BACKGROUND OF THE INVENTION
The conventional vane-type pump generally comprises a stator, a rotor and at least one blade, wherein the stator has a room defined therein. The stator has an inlet and an outlet so that the room communicates with outside of the stator. Fluid enters into the room via the inlet and leaves the room via the outlet. The rotor is eccentrically located in the room and the outer periphery of the rotor is in contact with the inner periphery of the room. Multiple blades are taken as an example. The rotor has slots for accommodating the blades therein. The blades each have one end pointing the center of the rotor and the other end of each of the blades is in contact with the inner periphery of the room. A space is defined between the inner periphery of the room and the outer periphery of the rotor. By the contact between the rotor, the blades and the inner periphery of the room, multiple partitions are defined to receive fluid.
When the rotor rotates back and forth, the blades are driven by the rotor and movable back and forth within the slots due to the movement of the rotor. The volumes of the partitions vary due to the back-and-forth movement of the blades, so that the fluid is sucked into the room via the inlet and leaved from the room via the outlet.
The centrifugal force generated from the blades due to the rotation of the rotor drives the blades outward so as to contact the distal ends of the blades with the inner periphery of the room to pump the fluid. However, when the viscosity of the fluid is high, there will be a gap between the distal ends and the inner periphery of the room and the transmission efficiency of the fluid is reduced.

The axles of the blades are engaged with the annular groove which guides the movement of the blades. The rotor is eccentrically located in the room and the axis of each of the blades points the center of the rotor, so that the shape of the inner periphery of the room is like oval inner periphery which is difficult to be machined during manufacturing processes.

The sharp distal end of the blade may vibrate when the fluid passes therethrough and noise is therefore generated. The vibration also generates partial therm stress which accelerates fatigue of the material at the distal end of the blade.

DETAILED DESCRIPTION OF THE PREFERRED
EMBODIMENTS
Referring to Figs. 1 and 2, the fluid transmission device of the present invention comprises a stator 10, a rotor 20, two blades 32, 34, two first pieces 40 and two second pieces 50. The stator 10 comprises a base 11 and a cover 12 which is connected to the base 11. A sealing member (not shown) may be connected between the base 11 and the cover 12, and multiple bolts (not shown) are used to connect the base 11 and the cover 12. As shown in Figs. 3 and 4, the stator 10 has a room 13 defined therein and the room 13 has a circular inner periphery 132. The stator 10 has an inlet 14 and an outlet 15. The inlet 14 and the outlet 15 communicate with the room 13 and outside of the stator
10. The stator 10 has a circular first recess 16 defined in the inner top of the room 13. A first protrusion 17 extends from the center of the first recess 16 and shares the center with the room 13. As shown in Fig. 5, the cover 12 has a second recess 18 defined in the underside thereof and faces the room 13. A second protrusion 19 extends from the center of the second recess 18 and shares the center with the room 13.
As shown in Figs. 2 to 7, the rotor 20 has a cylindrical body 21 and a shaft 22 which extends through the cylindrical body 21. The cylindrical body 21 is eccentrically located in the room 13 and the outer periphery of the cylindrical body 21 is tangent to the inner periphery 132 of the room 13. The inlet 14 and the outlet 15 are respectively located adjacent to the position where the outer periphery of the cylindrical body 21 is tangent to the inner periphery 132 of the room 13. The shaft 22 has one end pivotably connected to the base 11 and the other end of the shaft 22 extends through the stator 10 so as to be connected with a power source such as a motor or an inverter motor (not shown). The shaft 22 is pivotably connected with a plurality of bearings or bushes (not shown) and the bearings are connected to the base 11 and the cover 12 so allow the shaft 22 to be rotated smoothly. Two slots 23 are defined diametrically in the outer periphery of the cylindrical body 21. One end of each of the slots 23 points the center of the cylindrical body 21 and the other end of each of the slots 23 communicates with the room 13. A groove 24 is defined in the end face of the cylindrical body 21 and two ends of the groove 24 respectively communicate with the slots 23. The two ends of the groove 24 are located close to the shaft 22.
The two blades 32, 34 are respectively located within the slots 23. The first end of each blade 32/34 points the axis of the cylindrical body 21, and the second end of each blade 32/34 is in contact with the inner periphery 132 of the room 13 so as to form a space for receiving fluid between the outer periphery of the cylindrical body 21 and the inner periphery 132 of the room 13.
The first pieces 40 and two second pieces 50 are respectively pivotably connected to the stator 10. The first pieces 40 are located adjacent to the inner bottom of the cylindrical body 21 and the second pieces 50 are located adjacent to the inner top of the cylindrical body 21. The first pieces 40 and the second pieces 50 are pivoted about the center of the room 13. Each of the first and second pieces 40, 50 comprises a ring 42/52 and a protrusion 44/54. The protrusion 44/54 is a curved protrusion and connected to the outer periphery of the ring 42/52. The first pieces 40 are pivotably connected to the first recess 16 so that the first pieces 40 are adjacent to the underside of the cylindrical body 21.
The rings 42 of the first pieces 40 are mounted to the first protrusion 17 so that the first pieces 40 are pivotabie about the center of the room 13. The second pieces 50 are pivotably connected to the second recess 18 so that the second pieces 50 are adjacent to the top of the cylindrical body 21. The rings 52 of the second pieces 50 are mounted to the second protrusion 19 so that the second pieces 50 are pivotable about the center of the room 13. The two blades 32, 34 are respectively and pivotably connected to the first pieces 40 and the second pieces 50 by two respective axles 322, 342. Two ends of the axle 342 are pivotably connected to the protrusions 44, 54 of the first and second pieces 40, 50. When the rotor 20 rotates, the first and second pieces 40, 50 drive the axles 322, 342 to make the blades 32, 34 be pivoted about the center of the room 13. In the meanwhile, the blades 32, 34 are linearly movable in the slots 23. The rings 42 are mounted to the first protrusion 17 so that when the first pieces 40 rotate, there will be no interference between the first pieces 40 and the first protrusion 17. Therefore, the rotation of the first pieces 40 is reliable. The rings 52 are mounted to the second protrusion 19 so that when the second pieces 50 rotate, there will be no interference between the second pieces 50 and the second protrusion 19. Therefore, the rotation of the second pieces 50 is reliable.
A curved face 324/344 is defined in the second end of each of the two blades 32, 34 and in contact with the inner periphery 132 of the room 13. The inner periphery 132 of the room 13 has a radius R1. Each of the axles 322, 342 is pivotable by a radius R2. The curved face 324/344 of the second end of each of the two blades 32, 34 has a radius R3. The relationship of the three radiuses can be expressed by the equation R3=R1-R2. The two blades 32, 34 and the first pieces 40 are pivoted about two respective centers of the curved faces 324, 344 (the axes of the axles 322, 342) such that the second ends of the two blades 32, 34 are in contact with the inner periphery 132 of the room 13.
Therefore, the efficiency of transmission of the fluid is increased and the manufacturing processes for making the room 13 are simplified.
A power source (not shown) is connected to the shaft 22 to rotate the rotor 20, the blades 32, 34 are rotated about the center of the room 13 and, the blades 32, 34 are respectively rotated relative to the first and second pieces 40, 50. The blades 32, 34 are moved along the slots 23. When the rotor 20 rotates clockwise, as shown in Figs. 8 and 9, the space for receiving fluid in the room 13 are varied along with the rotation of the rotor 20 in the room 13, such that the fluid is sucked into the room 13 via the inlet 14 and the fluid is transmitted by the blades 32, 34 and then flows out from the outlet 15. When the rotor 20 rotates counter-clockwise, the fluid is sucked into the room 13 via the outlet 15 and the fluid is transmitted by the blades 32, 34 and then flows out from the inlet 14. Therefore, by controlling the direction of rotation of the rotor 20, the fluid can be transmitted in desired direction.
When the rotor 20 rotates, the blades 32, 34 are rotated about the respective axles 322, 342, and the axles 322, 342 move circularly about the center of the room 13 By cooperation of the radius R3 of the curved faces 324, 344, the curved faces 324, 344 of the blades 32, 34 are in contact with the inner periphery 132 of the room 13 without interference so as to increase the efficiency of transmission of fluid. The inner periphery 132 of the room 13 is around inner periphery which reduces the difficulties of machining.
Furthermore, when the blades 32, 34 move in the slots 23 back and forth, because the first ends of the two blades 32, 34 point the center of the room 13, and the two slots 23 are in communication with each other via the grooves 24, so that the fluid within the space between the two respective first ends of the blades 32, 34 and the shaft 22 flows between the two slots 23 via the grooves 24.
This avoids the positive/negative pressure applied to the two blades 32, 34 so that the blades 32, 34 move smoothly.
The number of the blades 32, 34 can be three or more than three, and the number of the pieces 40, 50 is also changed along with the change of the blades 32, 34. The number of the slots 23 is correspondingly changed to accommodate the blades 32, 34.
Fig. 10 shows the second embodiment, the differences between the first and second embodiments are that each of the first recesses 16 of the stator 10 has a first dim 162 in the inner end thereof so as to reduce the contact area between the first pieces 40 and the first recesses 16 and reduce the friction between the first pieces 40 and the base 11. Each of the second recess 18 of the stator 10 has a second dim 182 in the inner end thereof so as to reduce the contact area between the second pieces 50 and the second recesses 18 and reduce the friction between the second pieces 50 and the base 11. Lubricant is received in each of the first and second dims 162, 182.

The outer periphery of the ring 54 of each of the second pieces 50 is in contact with the inner wall of the second recess. The first and second pieces 40, 50 respectively rotate about the center of the room '13, because the outer periphery of the ring 44/54 is in contact with the inner periphery of the first/second recess, so that the rotation of the first and second pieces 40, 50 are reliable. The blade 32 is connected to an axle 322 which is pivotably connected between the protrusions 44, 54 of the first and second pieces 40, 50. The blade 34 is connected to an axle 342 which is pivotably connected between the protrusion 44, 54 of the other two first and second pieces 40, 50. When the rotor 20 rotates, the first and second pieces 40, 50 drive the blades 32, 34 by the axles 322, 342 and the blades 32, 34 rotate about the center of the room 13. The blades 32, 34 move along the slots 23 back and forth.

The cylindrical body 21 is eccentrically located in the room 13 and the outer periphery of the cylindrical body 21 is tangent to the inner periphery 132 of the room 13. The inlet 14 and the outlet 15 are respectively located adjacent to the position where the outer periphery of the cylindrical body 21 is tangent to the inner periphery 132 of the room 13. The shaft 22 has one end pivotably connected to the base 11 and the other end of the shaft 22 extends through the stator 10 so as to be connected with a power source such as a motor or an inverter motor (not shown). The shaft 22 is pivotably connected with a plurality of bearings or bushes (not shown) and the bearings are connected to the base 11 and the cover 12 so allow the shaft 22 to be rotated smoothly. Two slots 23 are defined diametrically in the outer periphery of the cylindrical body 21. One end of each of the slots 23 points the center of the cylindrical body 21 and the other end of each of the slots 23 communicates with the room 13. A groove 24 is defined in the end face of the cylindrical body 21 and two ends of the groove 24 respectively communicate with the slots 23. The two ends of the groove 24 are located close to the shaft 22.
The two blades 32, 34 are respectively located within the slots 23. The first end of each blade 32/34 points the axis of the cylindrical body 21, and the second end of each blade 32/34 is in contact with the inner periphery 132 of the room 13 so as to form a space for receiving fluid between the outer periphery of the cylindrical body 21 and the inner periphery 132 of the room 13.
The first pieces 40 and two second pieces 50 are respectively pivotably connected to the stator 10. The first pieces 40 are located adjacent to the inner bottom of the cylindrical body 21 and the second pieces 50 are located adjacent to the inner top of the cylindrical body 21. The first pieces 40 and the second pieces 50 are pivoted about the center of the room 13. Each of the first and second pieces 40, 50 comprises a ring 42/52 and a protrusion 44/54. The protrusion 44/54 is a curved protrusion and connected to the outer periphery of the ring 42/52. The first pieces 40 are pivotably connected to the first recess 16 so that the first pieces 40 are adjacent to the underside of the cylindrical body 21.
The rings 42 of the first pieces 40 are mounted to the first protrusion 17 so that the first pieces 40 are pivotabie about the center of the room 13. The second pieces 50 are pivotably connected to the second recess 18 so that the second pieces 50 are adjacent to the top of the cylindrical body 21. The rings 52 of the second pieces 50 are mounted to the second protrusion 19 so that the second pieces 50 are pivotable about the center of the room 13. The two blades 32, 34 are respectively and pivotably connected to the first pieces 40 and the second pieces 50 by two respective axles 322, 342. Two ends of the axle 342 are pivotably connected to the protrusions 44, 54 of the first and second pieces 40, 50. When the rotor 20 rotates, the first and second pieces 40, 50 drive the axles 322, 342 to make the blades 32, 34 be pivoted about the center of the room 13. In the meanwhile, the blades 32, 34 are linearly movable in the slots 23. The rings 42 are mounted to the first protrusion 17 so that when the first pieces 40 rotate, there will be no interference between the first pieces 40 and the first protrusion 17. Therefore, the rotation of the first pieces 40 is reliable. The rings 52 are mounted to the second protrusion 19 so that when the second pieces 50 rotate, there will be no interference between the second pieces 50 and the second protrusion 19. Therefore, the rotation of the second pieces 50 is reliable.

Each of the axles 322, 342 is pivotable by a radius R2. The curved face 324/344 of the second end of each of the two blades 32, 34 has a radius R3. The relationship of the three radiuses can be expressed by the equation R3=R1-R2. The two blades 32, 34 and the first pieces 40 are pivoted about two respective centers of the curved faces 324, 344 (the axes of the axles 322, 342) such that the second ends of the two blades 32, 34 are in contact with the inner periphery 132 of the room 13.
Therefore, the efficiency of transmission of the fluid is increased and the manufacturing processes for making the room 13 are simplified.
A power source (not shown) is connected to the shaft 22 to rotate the rotor 20, the blades 32, 34 are rotated about the center of the room 13 and, the blades 32, 34 are respectively rotated relative to the first and second pieces 40, 50. The blades 32, 34 are moved along the slots 23. When the rotor 20 rotates clockwise, as shown in Figs. 8 and 9, the space for receiving fluid in the room 13 are varied along with the rotation of the rotor 20 in the room 13, such that the fluid is sucked into the room 13 via the inlet 14 and the fluid is transmitted by the blades 32, 34 and then flows out from the outlet 15. When the rotor 20 rotates counter-clockwise, the fluid is sucked into the room 13 via the outlet 15 and the fluid is transmitted by the blades 32, 34 and then flows out from the inlet 14. Therefore, by controlling the direction of rotation of the rotor 20, the fluid can be transmitted in desired direction.
When the rotor 20 rotates, the blades 32, 34 are rotated about the respective axles 322, 342, and the axles 322, 342 move circularly about the center of the room 13 By cooperation of the radius R3 of the curved faces 324, 344, the curved faces 324, 344 of the blades 32, 34 are in contact with the inner periphery 132 of the room 13 without interference so as to increase the efficiency of transmission of fluid. The inner periphery 132 of the room 13 is around inner periphery which reduces the difficulties of machining.
Furthermore, when the blades 32, 34 move in the slots 23 back and forth, because the first ends of the two blades 32, 34 point the center of the room 13, and the two slots 23 are in communication with each other via the grooves 24, so that the fluid within the space between the two respective first ends of the blades 32, 34 and the shaft 22 flows between the two slots 23 via the grooves 24.
This avoids the positive/negative pressure applied to the two blades 32, 34 so that the blades 32, 34 move smoothly.
