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.

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： Disclosed is a compressor designed to facilitate the assembling of the thrust bearing and reduce noise. A swash plate which moves in responsive to the drive shaft is arranged in a crank chamber defined in a pair of cylinder blocks. Ring washers are held between both bosses of the swash plate and seats formed on both cylinder blocks. Wedge-like clearances are formed between the washers and the seats of the cylinder blocks for the effective introduction of the refrigerant gas by the yawing of the swash plate which occurs as the compressor runs. At this time, the washers, together with the lubrication oil mist contained in the refrigerant gas, constitute the dynamic bearing to support the swash plate and permit the relative movement of the swash plate to the cylinder blocks.
