    摘要: A housing includes a crank chamber and cylinder bores. Pistons are accommodated in the cylinder bores. A drive shaft is supported by the housing to pass through the crank chamber. A lug plate is fixed to the drive shaft. The pistons are coupled to the lug plate, which converts rotation of the drive shaft into reciprocation of the pistons and compresses gas in the cylinder bores. A thrust bearing is located between the housing and the lug plate and transmits a thrust load applied to the lug plate. The thrust bearing includes a front race located next to the housing, a rear race located next to the lug plate, and rollers located between the front and rear races. A front seat for supporting the front race is formed on the housing. A rear seat for supporting the rear race is formed on the lug plate. The diameters of the front and rear seats are different, which causes elastic deformation of the races when a thrust load is applied.

    摘要: A housing of a compressor has a shutter chamber for accommodating a shutter. The shutter moves between a closed position, where the shutter stops flow of gas from an external circuit into a suction chamber, and an open position, where the shutter permits the gas flow in response to the tilting motion of a swash plate. A coil spring, which has a conical shape, is located in the shutter chamber to bias the shutter in a direction toward the open position from the closed position. The spring is arranged to prevent the spring from sliding against the inner wall of the shutter chamber when the spring is expanded or contracted by movement of the shutter member.

    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 compressor comprises a plurality of compression chambers used for compressing gas. A gas chamber includes one of a suction chamber for supplying the gas to the compression chambers and a discharge chamber for receiving the compressed gas from the compression chambers. A plate member is located between the compression chambers and the gas chamber. The plate member has a plurality of ports respectively arranged in association with the compression chambers for connecting each compression chamber with the gas chamber. A plurality of valve flaps are respectively arranged in association with the ports. Each of the valve flaps faces the plate member to selectively open and close the associated port. Each valve flap has a proximal end supported on the plate member. The plate member has at least one groove formed thereon and facing the proximal end of each valve flap. Foreign matter enters between the proximal end of each valve flap and the plate member and is collected by the groove. The groove extends over at least two valve flaps.

    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 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.

    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.
