摘要： A variable-capacity compressor capable of improving starting performance of the compressor and eliminating the risk of the compressor becoming uncontrollable due to contamination or the like in a refrigerant is disclosed. An opening passage allowing the control pressure chamber to communicate with a suction chamber is provided separately from a bleed passage, a valve housing chamber is formed on the opening passage, and the opening passage is formed by including an upstream-side opening passage allowing the control pressure chamber to communicate with the valve housing chamber and a downstream-side opening passage allowing the valve housing chamber to communicate with the suction chamber. A valve body housed so as to open/close the downstream-side opening passage and a biasing means biasing the valve body in an opening direction are provided. The valve housing chamber is connected to the downstream side of a pressure control valve provided on a supply passage.

摘要： A swash plate type variable displacement compressor according to the present invention includes a housing having a suction chamber, a discharge chamber, a swash plate chamber, and a plurality of cylinder bores, a drive shaft, a swash plate, a link mechanism, a plurality of pistons reciprocally received in the respective cylinder bores, a conversion mechanism, an actuator that changes the inclination angle of the swash plate, and a control mechanism that controls the actuator. The link mechanism disposed between the drive shaft and the swash plate allows a change in inclination angle of the swash plate with respect to a plane extending perpendicularly to the axis of rotation of the drive shaft. The conversion mechanism converts the rotation of the swash plate into reciprocal movement of the pistons in the cylinder bores with a stroke length according to the inclination angle of the swash plate.

摘要： A variable displacement swash compressor includes a housing, a drive shaft, a swash plate, a link mechanism, a piston, a conversion mechanism, an actuator, and a control mechanism. The swash plate is rotatable together with the drive shaft in a swash plate chamber. The conversion mechanism reciprocates the piston in a cylinder bore. The actuator changes the inclination angle of the swash plate. The actuator is rotatable integrally with the drive shaft. The actuator includes a partitioning body, a movable body, and a control pressure chamber. The control mechanism changes the pressure of the control pressure chamber to move the movable body. The movable body is adapted to pull the swash plate and increase the inclination angle when the pressure of the control pressure chamber increases.

摘要： A mobile body and a swash plate are coupled to each other via a columnar coupling pin provided on an outer peripheral part of the swash plate. An insertion hole through which the coupling pin is passed is formed in the swash plate. The insertion hole has a guide surface for guiding the coupling pin and for changing the inclination angle of the swash plate following movement of a mobile body to the axial direction of a rotation shaft. The guide surface has a flat surface part which is inclined to a moving direction of the mobile body. The flat surface part is set such that a perpendicular line of the flat surface part and an axial line of the rotation shaft cross in a region surrounded by a sliding part, viewed from a direction orthogonal to both an axial direction of the rotation shaft and a first direction.

摘要： A fourth pin that slides on a rotary shaft is provided to a swash plate. A guiding surface for guiding the fourth pin is provided to the rotary shaft. The fourth pin is guided by the guiding surface, the swash plate is supported by the rotary shaft via the fourth pin, and a force having a component in a direction orthogonal to the direction of movement of a movable body acting on the swash plate is thereby reduced. Accordingly, there is a reduction in the force, which has a component in a direction orthogonal to the direction of movement of the movable body, acting on a coupling section of the movable body via a third pin from the swash plate. As a result, when the inclination of the swash plate is changed, unwanted tilting of the movable body relative to the direction of movement is suppressed.

摘要： The valve body has a first valve part and a second valve part. The first valve part has an end surface seal part that is brought into contact with a seat part of a first valve seat part and closes a bleed passage. The second valve part has an external surface seal part that enters the second valve hole and closes the supply passage. When the opening degree of the first valve part is maximum, the seal length of the external surface seal part along the moving direction of the valve body is shorter than the distance between the end surface seal part and the seat part along the moving direction of the valve body.

摘要： A control valve according to one embodiment includes a shaft that transmits the solenoidal force to a valve element. The control valve, in one example, ensures high pressure resistance at a mounting part where a control valve is mounted in a variable displacement compressor. A solenoid includes a bottomed sleeve into which the pressure of refrigerant is introduced, a core secured coaxially to the sleeve, a plunger, contained in the sleeve on its bottom side, which is displaceable integrally with the shaft in a direction of axis line, a first spring that applies the biasing force in a valve opening direction to the shaft, a second spring that applies the biasing force in a valve closing direction to the plunger, and a shaft support member, which is press-fitted such that the shaft support member is secured to an inner wall of the sleeve near its bottom portion. The second spring is set between the shaft support member and the plunger.
