摘要： A control valve used for a variable displacement type compressor. The compressor has a crank chamber, a discharge pressure zone, and a supply passage. The supply passage connects the crank chamber to the discharge pressure zone. The control valve is located in the supply passage. The control valve has a valve body. The valve body adjusts the size of the opening of the supply passage in accordance with the discharge pressure. The valve body is exposed to the pressure of the supply passage. The valve body moves in accordance with the discharge pressure such that the displacement is varied to counter changes of the discharge pressure. The direction in which the valve body moves in response to an increase of the discharge is the same as the direction in which the valve body moves when the pressure of the supply passage increases.

摘要： A control valve is used for a variable displacement compressor installed in a refrigerant circuit of a vehicle air conditioner. The control valve has a valve housing. A valve chamber is defined in the valve housing. A valve body is accommodated in the valve chamber. A pressure sensing chamber is defined in the valve housing. A pressure sensing member separates the pressure sensing chamber into a first pressure chamber and a second pressure chamber. The pressure at a first location in the refrigerant circuit is applied to the first pressure chamber. The pressure at a second location in the refrigerant circuit, which is downstream of the first location, is applied to the second pressure chamber. The pressure sensing member moves the valve body in accordance with the pressure difference between the first pressure chamber and the second pressure chamber such that the displacement of the compressor is varied to counter changes of the pressure difference. At least one of the first pressure chamber and the second pressure chamber forms a part of the refrigerant circuit.

摘要： Disclosed is a compressor having a drive shaft in a crank chamber and a swash plate supported on the drive shaft for integral rotation therewith to drive a piston in a cylinder bore. The piston compresses gas sucked from a suction chamber into the cylinder bore and discharges the compressed gas to a discharge chamber and the amount of the discharged gas is variable between a minimum and maximum values based on variation of the inclined angle of the swash plate between a minimum and maximum values. The compressor comprises a passage for leading the gas into the crank chamber from the discharge chamber to alter the inclined angle of the swash plate, a valve for selectively opening and closing the passage to lead the gas into the crank chamber via the passage when the valve opens the passage, and a control apparatus for controlling the inclined angle of the swash plate, which operates in accordance with the operation of the valve to hold the swash plate at the minimum inclined angle when the valve means opens the passage.

摘要： In a variable displacement type gear pump, each of a main gear pump portion and a sub gear pump portion has a drive gear, a driven gear engaging with the drive gear, and an urging portion applying radial load to the drive and driven gears. A bypass passage returns fluid in a discharge-side space of the sub gear pump portion to a suction passage. An opening and closing valve opens the bypass passage in a small displacement operational state. A drive shaft supports the main drive gear and the sub drive gear. A driven shaft supports the main driven gear and the sub driven gear. The drive gears and the driven gears are rotated in accordance with a rotation of the drive shaft. The drive and driven shafts transmit the radial load in the main gear pump portion to the sub gear pump portion in the small displacement operational state.

摘要： A variable displacement type gear pump has gear chambers, one of which is a specific gear chamber. A suction passage is formed in the housing so as to communicate with suction-side spaces. An outlet passage communicates with discharge-side spaces. A return passage returns the fluid discharged to the discharge-side space of the specific gear chamber to the suction passage. The return passage communicates with the suction passage at a confluence portion located upstream side of the suction-side space. An opening and closing valve opens the return passage in a small displacement operational state. A check valve is located between the discharge-side space of the specific gear chamber and the outlet passage for preventing the fluid discharged from the gear chamber other than the specific gear chamber from flowing into the discharge-side space of the specific gear chamber in the small displacement operational state.

摘要： An axial multi-piston compressor comprises a drive shaft, a cylinder block having cylinder bores formed therein and surrounding the drive shaft, and a plurality of pistons slidably received in the cylinder bores, respectively, wherein the pistons are successively reciprocated in the cylinder bores by a rotation of the drive shaft so that a suction stroke and a discharge stroke are alternately executed in each of the cylinder bores. During the suction stroke, a fluid is introduced into the cylinder bore, and during the compression stroke, the introduced fluid is compressed and discharged from the cylinder bore such that a residual part of the compressed fluid is inevitably left in the cylinder bore when the compression stroke is finished. The compressor further comprises a rotary valve for allowing the residual part of the compressed fluid to escape from the cylinder bore into another cylinder bore not governed by the compression stroke, whereby a pressure of the residual part of the compressed fluid can be lowered.

摘要： The variable displacement gear pump for a loading system in an industrial vehicle has main and sub gear pump portions, suction, discharge and bypass passages, and check and opening valves. The main gear pump portion has main drive and driven gears, and has suction and discharge side spaces. The sub gear pump portion has sub drive and driven gears, and has suction and discharge side spaces. The bypass passage returns hydraulic fluid in the discharge-side space of the sub gear pump portion to the suction passage. The check valve prevents hydraulic fluid in the discharge-side space of the main gear pump portion from flowing to that of the sub gear pump portion. The opening valve is used for opening and closing the bypass passage, and closes the bypass passage due to a pressure in a discharge conduit of the loading system increased by the load applied to the loading system.

摘要： A roots pump including a pair of multi-lobe rotors is disclosed. The pair of rotors each include a first straight portion and a second straight portion. The first straight portion is provided on one of end portions of the rotary shaft of the rotor in an axial direction to extend straight along the axial direction. The straight portion is provided on the other one of the end portions to extend straight along the axial direction. The phases of the first straight portion and the second straight portion are displaced along the circumferential direction of the associated rotary shaft. Each of the pair of rotors further includes a coupling portion, which couples the first straight portion and the second straight portion. The coupling portions of the pair of rotors are engaged with each other to suppress fluid leakage between the pair of rotors.
