摘要： A compressor includes a discharge chamber, compressor chamber, valve plate, and discharge reed valve. The valve plate includes a fixing surface, exposed to the discharge chamber, and a discharge port, which communicates the discharge chamber and the compression chamber. The discharge reed valve includes a fixed portion, fixed to the fixing surface, a base portion, separable from the valve plate, and a valve portion, which closes the discharge port. The valve plate includes an annular seal surface, recessed groove, receiving surface, and support surface. The seal surface contacts the valve portion around the discharge port. The recessed groove is arranged in the fixing surface outward from the seal surface. The receiving surface is flush with the fixing surface and contacts a distal region of the valve portion. The support surface is flush with the fixing surface and contacts a central region of the valve portion.

摘要： To provide a motor-driven turbo compressor that has high durability and is capable of surely improving efficiency of a refrigeration circuit. In the compressor of the present invention, an intermediate pressure port 31 through which a first discharge chamber 25 and a first chamber 29a communicate with each other is formed in a front housing 11. In the front housing 11, an injection port 43 through which a receiver 103 and a second chamber 29b communicate with each other is formed. An intermediate pressure refrigerant discharged to the first discharge chamber 25 flows into the first chamber 29a through an intermediate pressure port 31. An injection refrigerant separated by the receiver 103 flows into the second chamber 29b. In the compressor, it is possible to cool an electric motor 5 with the intermediate pressure refrigerant and the injection refrigerant. The intermediate pressure refrigerant and the injection refrigerant circulate through a second suction port 37 as a mixed refrigerant. Therefore, in the compressor, it is possible to suitably suppress a temperature rise of the mixed refrigerant when the mixed refrigerant flows into a second impeller chamber 19.

摘要： A compressor has a compression chamber formed in a cylinder block, a suction passage formed upstream of the compression chamber and a suction throttle valve formed in the suction passage for adjusting opening of the suction passage. The suction throttle valve has a valve hole and a valve seat formed around the valve hole, a valve body for opening and closing the valve hole and an urging member for urging the valve body in the direction which causes the valve hole to be closed. The urging member is a disk spring. The spring characteristics of the disk spring includes a range where the increasing rate of the load required for displacement of the disk spring is reduced with an increase of displacement of the disk spring. The displacement range of the valve body includes a range where the increasing rate of the load of the disk spring is reduced with an increase of the displacement of the disk spring.

摘要： A variable displacement compressor has a housing, a piston, a drive shaft, a rotor, a cam plate and a hinge mechanism. The hinge mechanism between the rotor and the cam plate guides the cam plate to incline and slide relative to the drive shaft. Thus, the displacement volume of the compressor is varied. The rotation of the drive shaft is converted to the reciprocation of the piston through the rotor, the hinge mechanism and the cam plate. The hinge mechanism includes first and second hinge elements that are respectively provided on the rotor and on the cam plate and engage each other. At least one of the first and second hinge elements has a degree of freedom for motion against the rotor and/or the cam plate to which it belongs.

摘要： Variable displacement compressors 30 may include a rotor 7 that is press-formed from a plate W. The rotor 7 is fixedly mounted on a drive shaft 6 and is coupled to a swash plate 8 via a hinge device 20. The hinge device 20 preferably permits the swash plate 8 to rotate with the rotor 7 as well as the drive shaft 6 and also may permit the swash plate 8 to change its inclination angle relative to the rotor 7 as well as the drive shaft 6. The swash plate 8 may be coupled to a piston(s) 11 that reciprocates within a cylinder bore(s) 2a.
