摘要： A piston type compressor includes a housing, which defines a crank chamber. A valve plate forms a part of the housing. A drive shaft is located in the crank chamber. A contact member is plastically deformed and press fitted to the drive shaft. An inner wall and a first sub-plate are located in the housing and limit the axial movement of the drive shaft, respectively. After the contact member is attached to the drive shaft, the axial load required to change the position of the contact member is greater than the maximum axial load applied to the drive shaft due to the increase of the pressure in the crank chamber, and less than the load applied to the contact member by the first sub-plate in accordance with the difference in the thermal expansion coefficient of the housing and the drive shaft.

摘要： A variable displacement compressor includes a supply passage for supplying refrigerant gas from a discharge chamber to a crank chamber and a bleed passage for bleeding the refrigerant gas from the crank chamber to a suction chamber. An oil separator is connected to a drive shaft and is located in the bleed passage. The oil separator rotates together with the drive shaft to centrifugally separate lubricant oil from the refrigerant gas that flows in the bleed passage. An oil chamber is formed in a compressor housing for receiving the separated oil. The pressure in the oil chamber is equal to or greater than the pressure in the crank chamber. The lubricant oil rapidly returns to the crank chamber through a return passage.

摘要： A rotor is fixed to a drive shaft supported by a housing. A swash plate is supported slidably and tiltably by the drive shaft. A hinge mechanism is provided between the rotor and swash plate. The hinge mechanism comprises two rotor-side protrusions provided in the rotor and a protruding portion provided in the swash plate. The protruding portion is inserted between side faces in which the two rotor-side protrusions face each other, and perform power transfer between the rotor and swash plate by two-dimensionally abutting against a side face of one of the rotor-side protrusions. A concavity is provided in the side face of the rotor-side protrusion. Therefore, an area of the side face of the rotor-side protrusion abutting on the side face of the swash-plate-side protrusion decreases, and smooth change of discharge volume is achieved while controlling processing cost.

摘要： A variable displacement compressor has a drive shaft, a rotor supported by the drive shaft, a drive plate supported by the drive shaft and a hinge mechanism located between the rotor and the drive plate. The hinge mechanism includes a cam, which is located on the rotor, and a guide portion, which is located on the drive plate. The cam has a cam surface, which has a predetermined profile. One of the cam surface and the guide portion slides against the other in accordance with inclination of the drive plate. The guide portion traces a path corresponding to the profile of the cam surface with respect to the cam. The path includes a first path corresponding to a small displacement region of the compressor and a second path corresponding to a large displacement region of the compressor. The profile of the cam surface is determined such that the first path and the second path bulge in a direction opposite to each other to compensate for fluctuation of a top dead center position of the piston.

摘要： In a piston type compressor, a piston is respectively accommodated in a plurality of cylinder bores arranged around a rotary shaft. A rotary valve has a suction guiding passage for introducing gas from a suction pressure region into a compression chamber when in communication therebetween. A suction timing control passage is formed in the rotary valve and is constantly in communication with the suction pressure region at first end, the suction timing control passage precedes the suction guiding passage communicating with the compression chamber at second end. A suction timing control valve is arranged in the control passage, having a valve body which opens and closes the control passage in response to difference between force resulting from pressure on a side of the suction pressure region to open the valve body and force resulting from pressure on a side of the compression chamber to close the valve body.

摘要： A variable displacement type swash plate compressor that prevents a drive shaft from moving axially when the difference between a crank chamber pressure and a cylinder bore pressure becomes excessive. A hinge mechanism has a support arm extending from a lug plate and a guide pin extends from a swash plate. The head portion of the guide pin fits in a guide hole formed in the support arm. A cutaway surface is formed in a part of the support arm that defines the guide hole. The cutaway surface forms a clearance in the hinge. The clearance permits the swash plate to move without pulling the drive shaft.

摘要： A variable displacement compressor is disclosed that draws refrigerant from a suction pressure zone and discharges the refrigerant to a discharge pressure zone, and controls displacement according to a pressure in a control pressure chamber. The compressor has a cam body, pistons, a supply passage, a release passage, and an on-off valve. The inclination angle of the cam body is changeable based on the pressure in the control pressure chamber. A piston reciprocates in each cylinder bore as the cam body rotates. The supply passage supplies the refrigerant in the discharge pressure zone to the control pressure chamber. The release passage releases the refrigerant in the control pressure chamber to the suction pressure zone. The on-off valve selectively opens and closes the release passage in response to changes of the temperature. The on-off valve shuts off the release passage when the temperature is equal to or higher than a predetermined temperature.

摘要： A variable displacement compressor includes a swash plate guiding member that rotates integrally with and inclines relative to a drive shaft, a swash plate supported by the guiding member, and a piston engaged with the swash plate via a shoe. A clutch is located between the guiding member and the swash plate. The clutch is switched between an engaged state, where the clutch permits the guiding member and the swash plate to rotate integrally, and a disengaged state, where the clutch permits the guiding member and the swash plate to rotate relative to each other. Therefore, the compressor is capable of switching between a state where improving the displacement controllability is prioritized and a state where reduction of mechanical loss between the swash plate and the shoes is prioritized.
