    摘要： A compressor includes a cylinder block having a cylinder bore, a first housing attached to a first end of the cylinder block, a second housing attached to a second end of the cylinder block, a crank chamber defined between the cylinder block and the first housing, a drive plate located in the crank chamber and mounted on a drive shaft, and a piston operably coupled to the drive plate and located in the cylinder bore. The drive plate is tiltable between a maximum inclination position and a minimum inclination position according to a difference between the pressure in the crank chamber and the pressure in the cylinder bore. The cylinder block has a shutter chamber opening to the first end and the second end. A shutter member is accommodated in the shutter chamber. The shutter member is movable between a first position and a second position in response to the inclination of the drive plate to selectively connect and disconnect an external circuit with an suction chamber. The drive plate is held at the minimum inclination position when the shutter member is positioned in the second position. The shutter chamber has a diameter that is constant in an axial direction with respect to the shutter chamber. The shutter member is removably inserted into the shutter chamber from the second end of the cylinder block.

    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 variable displacement compressor having a rotary shaft and a swash plate is described. The swash plate is mounted on the shaft and rotates integrally with the shaft. The swash plate tilts between a maximum inclined angle and a minimum inclined angle and is connected to a plurality of pistons. The inclined angle of the swash plate is altered by the difference between the pressure in a crank chamber and the pressure in a suction chamber. Each piston reciprocates inside a cylinder bore with a stroke determined by the inclined angle of the swash plate and compresses refrigerant gas, which includes oil mist. A spool is arranged adjacent to the swash plate on the shaft. On the shaft, a thrust bearing is provided between the swash plate and the spool, and a radial bearing is provided in the spool. The spool has an opening opposed to the swash plate. Grooves that allow the flow of refrigerant gas into the spool are formed at the opening in the walls of the spool.

    摘要： A control valve used in a variable displacement compressor. The valve includes a valve chamber having a valve hole. A valve body is accommodated in the valve chamber for selectively closing and opening the valve hole. An opening spring urges the valve body in a direction opening the valve hole. An actuator generates force in a direction closing the valve hole. A solenoid rod transmits the force of the actuator to the valve body. A pressure sensing chamber is defined independently from the valve chamber to receive refrigerant from a suction passage. A pressure sensing member is located in the sensing chamber for sensing the pressure in the sensing chamber. A pressure sensing rod transmits the pressure sensed by the sensing member to the valve body. A compression spring, a cap and stoppers maintain proper alignment of the pressure sensing member. The valve body is moved based on the refrigerant pressure sensed by the sensing member, the force of the spring and on the force of the actuator.

    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 control valve for a variable displacement compressor. The control valve has a valve body for regulating a gas passage. A bellows actuates the valve body in accordance with an operating pressure introduced to a pressure sensing chamber. A solenoid biases the valve body with a force based on the electric current supplied to the solenoid. A cylindrical cap is fitted to a cylindrical portion provided on a housing of the control valve. The bellows is located in the pressure sensing chamber. The axial position of the cap in relation to the cylindrical portion is adjusted such that the bellows is positioned at a specific initial position when a pressure having a predetermined magnitude is introduced to the pressure sensing chamber and when a current having a predetermined value is supplied to the solenoid. The cap is secured to the cylindrical portion by crimping with the bellows positioned at the initial position.
