摘要： A compressor has a swash plate tiltable between a maximum and minimum inclining angles with respect to an axis of the drive shaft according to a difference between pressures in a crank chamber and a suction chamber. An electromagnetic valve is disposed in a pressure passage, and opens or closes the pressure passage according to instruction of an external computer. This instruction is based on an operation status of the compressor so that the electromagnetic valve adjusts the pressure in the crank chamber. The pressure passage connects the crank chamber and the suction chamber. The swash plate is inclined toward the maximum inclining angle when the pressure passage is open to release the pressure in the crank chamber to the suction chamber. The swash plate is inclined toward the minimum inclining angle when the pressure passage is closed to increase the pressure in the crank chamber. A disconnecting element is disposed between the external circuit and the suction chamber to disconnect the external circuit with the suction chamber in association with the swash plate driven to the minimum inclining angle.

摘要： A compressor has an internal refrigerant gas passage selectively connected to and disconnected with an external refrigerant circuit separately provided from the compressor. The compressor has a plurality of pistons reciprocable in a plurality of cylinder bores in a housing for compressing gas. The compressor comprises a drive shaft rotatably supported by the housing. A swash plate is supported on the drive shaft for integral rotation with inclining motion with respect to the drive shaft. The swash plate is movable between a maximum inclined angle and a minimum inclined angle. A rotary valve is disposed in the middle of the internal refrigerant gas passage for synchronously rotating with the drive shaft. The rotary valve has a refrigerant supply passage for sequentially supplying the refrigerant gas in the internal refrigerant gas passage to each cylinder bore. A disconnecting device disconnects the external refrigerant circuit from the internal refrigerant gas passage when the swash plate is at the minimum inclined angle.

摘要： A sealing structure for the shaft of a compressor. The sealing apparatus includes an inner ring, and outer ring, and a support ring. The inner ring and the outer rings have flexible annular lips that contact the surface of the rotary shaft. The support ring supports the inner lip and determines the position of the inner lip. The first lip permits fluid leakage along the surface of the shaft, while the second lip forms a fluid-tight seal with the shaft. The support ring prevents the internal pressure of the compressor from pressing the first lip against the shaft with excessive force, which extends the life of the sealing apparatus.

摘要： A variable displacement type compressor is disclosed. The compressor includes a housing, a cylinder bore within the housing, a piston located in the cylinder bore, a drive shaft rotatably supported by the housing, a rotary support mounted on the drive shaft, and a cam plate connected to the piston. The cam plate is supported tiltably on the drive shaft and is slidable in axial directions of the drive shaft. The cam plate inclines between a maximum inclination position and a minimum inclination position when the displacement of the compressor is changed. A first moment is applied to the cam plate by a compression reaction force of the piston when the compressor is operating. A hinge mechanism is located between the rotary support and the cam plate. The cam plate is rotated integrally with the drive shaft, the rotary support, and the hinge mechanism. An urging device is located between the rotary support and the cam plate for urging the cam plate toward the minimum go inclination angle position An applying mechanism applies a second moment to the swash plate in the same direction as the first moment when the compressor is not operating.

摘要： A compressor has a swash (slanting-cam) plate located in a crank chamber and mounted on a drive shaft. The cam plate is tiltable between a maximum inclined angle position and a minimum inclined angle position with respect to a plane perpendicular to an axis of a drive shaft according to a difference between the pressures in the crank chamber and a cylinder bore. The cam plate varies the stroke of a piston in the cylinder bore based on an inclination thereof to control the displacement of the compressor. A shutter member is movable between a first position where the shutter member connects a external circuit with a suction chamber and a second position where the shutter member disconnects the external circuit with the suction chamber in response to the inclination of the cam plate. The cam plate moves the shutter member to the second position when the cam plate is at the minimum inclined angle position to minimize the displacement of the compressor. A valve plate is located between the cylinder bore and a gas chamber. The gas chamber is either the suction chamber or the discharge chamber. The valve plate has a port that connects the cylinder bore with the gas chamber and a valve that has open and shut positions. A passage is defined between the valve plate and the valve when the valve is shut to connect the cylinder bore with the gas chamber.

摘要： A compressor has a housing body, a drive shaft, a swash plate, and a piston. The swash plate converts rotation of the drive shaft to reciprocating movement of the piston in a cylinder bore. The piston compresses gas supplied to the cylinder bore from an external circuit via a suction chamber and discharges the compressed gas to a discharge chamber. The swash plate is tiltable with respect to a plane perpendicular to the longitudinal axis of the drive shaft according to differential pressure between the crank chamber and the suction chamber. The swash plate controls the displacement of the compressor based on the inclination thereof. A spool is movable longitudinally between a first position and a second position in response to the inclination of the swash plate. The spool connects the external circuit with the suction chamber in the first position and disconnects the external circuit from the suction chamber in the second position. The housing body has a surface slidably engaged by the spool. A coating layer is provided on at least one of the spool and the slide surface to reduce frictional resistance occurring due to the sliding movement of the spool on the slide surface. A second coating layer is provided on an end surface of the spool to lubricate and thereby reduce frictional resistance with the housing surface along the periphery of the suction passage leading into the shutter chamber occurring due to rotation of the spool, and also to improve the seal between the end surface of the spool and the housing when in the second position closing off the suction passage.
