摘要： An improvement of a piston type compressor is disclosed. The compressor has a cylinder block that includes a plurality of cylinder bores and a plurality of suction passages. Each of the suction passages extends through the cylinder block to connect a crank chamber with a suction chamber. The suction chamber is connected with the cylinder bores via a plurality of suction ports located in association with the cylinder bores. Each cylinder bore accommodating a piston that moves therein to circulate gas between the compressor and an external gas circuit. The gas introduced into the crank chamber from the external gas circuit is supplied to the suction chamber through each suction passage and is supplied from the suction chamber to each cylinder bore through an associated suction port. The suction passages are smaller in number than the cylinder bores. The suction ports are disposed in the vicinity of an opening of the suction passages.

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.

摘要： A compressor includes a housing body and a drive shaft rotatably supported in the housing body. A drive plate is mounted on the drive shaft. Cylinder bores are defined in the housing body. Pistons are operably coupled to the drive plate and are disposed in the cylinder bores. The drive plate converts rotation of the drive shaft to reciprocating movement of the pistons in the cylinder bores. Each piston compresses gas supplied from a suction chamber to the associated cylinder bore and discharges the compressed gas to a discharge chamber. Force to minimize displacement of the drive shaft in the axial direction thereof adjusts in accordance with at least one of pressure in the discharge chamber and a rotation speed of the drive shaft.

摘要： A refrigerant compressor, typically a swash plate type refrigerant compressor for compressing refrigerant gas containing therein lubricating oil, which has axially combined cylinder blocks having a plurality of cylinder bores in which a plurality of pistons reciprocate to implement suction and compression of refrigerant gas as well as discharge of the compressed refrigerant gas. The cylinder blocks further have a swash plate chamber for a swash plate supported by a sliding type thrust bearings, receiving the refrigerant gas returning from an exterior of the compressor, and an axially extending central through-bore for a drive shaft supported by radial bearings. The compressor has a lubricating oil system which includes a fluid passageway for supplying a part of the refrigerant gas containing the lubricating oil from refrigerant gas inlet passageways in the cylinder blocks into the central bore to lubricate the sliding type thrust bearings and the radial bearings. Additional gas passageways may be provided in the valve plate for providing communication between some cylinder bores and the central bore in synchronism with opening of suction valves of some cylinder bores so that introduction of the part of the refrigerant gas into the central bore from the swash plate is promoted.
