摘要： A compressor has a compression chamber and a discharge region. The discharge region receives the compressed gas discharged from the compression chamber. A relief valve is mounted to inside of the wall in the discharge region. The relief valve connects the discharge region with the exterior of the compressor so as to discharge the excessively raised pressure in the discharge region.

摘要： A swash plate type compressor incorporating therein a swash plate having an annular rail raised from each flat face thereof for providing a sliding-contact surface being in contact with sliding-contact surface portions of respective shoes which constitute a rotation-to-reciprocation conversion unit arranged between the swash plate and double-headed pistons reciprocating axial cylinder bores of the compressor. The sliding-contact surfaces of respective shoes bulge outward and have a radius of curvature "R" in the range of 800 through 1600 millimeters which is smaller than that of the conventional shoes of a swash plate type compressor, so that relatively large wedge shaped gaps are formed between the respective shoes and the swash plate to thereby stably and constantly hold lubricating oil.

The refrigerant is discharged into the external refrigerating circuit through the front and rear discharge chambers, .and the front and rear discharge ports. A discharge passage is provided within the drive shaft, and interconnects the front and rear discharge chambers. A valve is provided at one end of the discharge passage to control the opening of the discharge port in relation to the pressure difference between the front and rear discharge chambers.

摘要： A valve assembly in a piston type refrigerant compressor is disclosed. The valve assembly includes a retainer formed integrally with a gasket plate for restricting the opening of a discharge reed valve of the compressor, and having on opposite sides at the distal portion thereof stay portions integral with the gasket plate for rigidly holding the retainer. According to the present invention, provision is made to guide some part of the refrigerant gas compressed in a cylinder bore to be discharged into a discharge chamber in such a way that the influence of the discharge gas pressure on the retainer at its distal end is reduced. In some embodiments of the invention, this is accomplished by guiding and allowing part of the gas to flow toward the proximal portion of the retainer to discharge the gas.

摘要： A swash plate type compressor comprising a swash plate accommodated in a swash plate chamber. Front and rear housings are attached to the cylinder block to form suction chambers and discharge chambers, respectively. A refrigerating medium is introduced from a suction inlet to the suction chambers via the swash plate chamber and discharged from the discharge chambers. A drive shaft is fixed to the swash plate for reciprocally moving pistons. The drive shaft has a discharge passage in the form of an axial bore formed in the drive shaft for connecting the front discharge chamber to the rear discharge chamber. The discharge passage is thus isolated from the suction system.

摘要： A multi-piston swash plate type compressor for an air-conditioning system used in a vehicle such as an automobile, including a cylinder block body having a swash plate chamber formed therein for receiving a swash plate and cylinder bores formed therein for receiving pistons which are reciprocated by rotation of the swash plate. The compressor has a suction chamber which is fed with a refrigerant including lubricating oil from an evaporator of the air-conditioning system and a discharge chamber which feeds the compressed refrigerant to a condenser of the air-conditioning system. When the compressed refrigerant is discharged from the cylinder bore into the discharge chamber through a discharge reed valve, all of the discharged refrigerant is impinged on the peripheral and inner wall so as to separate the lubricating oil from the refrigerant, whereby an effective damping and sealing oil layer is formed between the discharge reed valve and the valve seat thereof.

摘要： A piston type compressor having a cylinder block in which a plurality of compression chambers permit a plurality of pistons to be reciprocated so as to compress a refrigerant sucked from a suction chamber formed in an end housing into the compression chambers through suction ports of a valve plate openably closed by a plurality of suction reed valves. The compressor also has a valve stop construction for stopping the movement of the suction reed valves when the valves reach the opening position thereof apart from the valve plate. The valve stop construction includes recessed seats formed in an axial end face of the cylinder block so as to permit a portion of the free end of respective suction reed valves to be first seated on the recessed seats, and to permit the remaining portion of the free end of the suction reed valves to be stably seated on the recessed seats. The gradual stoppage of the suction reed valves suppresses vibration of the valves and prevents noise.

摘要： A multi-cylinder piston-operated compressor having a combined cylinder block closed on both axial ends by front and rear housing and provided therein with a reciprocative piston mechanism, for sucking, compressing, and discharging a refrigerant gas, and a connecting flange, from which the refrigerant gas after compression is sent toward a cooling circuit. The connecting flange defines a muffling chamber in cooperation with a circumferential section of the combined cylinder block for suppressing the pulsation in discharge pressure of the refrigerant gas. The compressor further has a gas expansion chamber in which an expansion and a partial collision of the compressed refrigerant gas spouted from orifices take plate to weaken the pulsation in the discharge pressure of the gas with the least discharge loss.

摘要： A piston type compressor having a cylinder block in which a plurality of compression chambers permitting a plurality of pistons to be reciprocated so as to compress a refrigerant gas pumped from a suction chamber formed in an end housing into the compression chambers through suction ports of a valve plate, openably closed by a suction valve mechanism with a plurality of suction reed valves, and to discharge the compressed refrigerant gas from the compression chambers into a discharge chamber formed in the end housing through discharge ports of the valve plate, are openably closed by a discharge valve mechanism having a plurality of discharge reed valves. The suction and discharge reed valves of the suction and discharge valve mechanisms are prevented from undergoing complicated and irregular vibrations by an asymmetrical arrangement of the suction and discharge ports of the valve plate, or by provision of asymmetrical through-openings to adjust mechanical flexibility to the suction and discharge reed valves for both reed valves.
