摘要： A compressor includes a drive shaft rotatably supported on cylinder block. A swash plate rotates in accordance with rotation of the drive shaft. A plurality of pistons reciprocate in the associated bores in the cylinder block in accordance with the rotation of the swash plate. First an second thrust bearings are provided in the cylinder block at both sides of the swash plate, and receive the axial loads applied to the swash plate and drive shaft according to the reciprocation of the pistons. The first thrust bearing has the first seat portion clamped at both sides by the swash plate and cylinder block and the second seat portion located apart from one of the swash plate and cylinder block.

摘要： In the present compressor, a retainer is prevented from being deformed without impairing the sealing performance of a metal gasket provided between a covering member for closing a compression chamber of a cylinder block assembly and a discharge valve forming plate. A discharge valve forming plate is provided between a valve plate having at least one discharge port through which a fluid compressed in a compression chamber of a cylinder block assembly is discharged into a discharge chamber of a housing and the cylinder block assembly. A retainer for restricting the magnitude of opening of a discharge valve is integrally formed in a metal gasket which is provided between the discharge valve forming plate and the housing. The housing is provided with a restricting section at a position corresponding to a proximal portion of a rising portion of the retainer for restricting the proximal portion of the top surface of a rising portion.

摘要： A gasket having a surface thereof coated with an elastic membrane and adapted to be interposed, together with a valve plate and a discharge valve member, between a cylinder block and a housing of a refrigerant compressor under compression. The gasket includes an outer sealing portion for sealing an outer circumference of the compressor against an atmospheric environment therearound, and an inner sealing portion, connected to the outer sealing portion, for sealing between a high pressure region and a low pressure region within the compressor. Each of the outer and inner sealing portions includes in its entirety a deformable ridge which is shaped as a convexly curved projection with an apex line continuously extending along a length of the each outer and inner sealing portion. When the gasket is located in a proper position in the compressor, the apex lines of the ridges of the respective sealing portions are abutted to the front or rear housing of the compressor.

摘要： A capacity type refrigerant compressor having a compression chamber in which a refrigerant introduced from a suction system is compressed and discharged as a compressed high pressure refrigerant, and an oil-separating and lubricating system for lubricating an interior of the compressor by an oil separated from the compressed refrigerant, which has an oil-separating unit to separate the oil from the compressed refrigerant, an oil-storing chamber storing the separated oil, an oil-supply passage to supply the oil from the oil-storing chamber to the suction system, a pressure-operated valve arranged in the oil supply passage to regulate an amount of flow of the oil, which includes a valve chamber and a movable valve spool in the valve chamber to control a communication between the upstream and downstream of the oil-supply passage. The valve spool element moves in response to a change in a pressure differential between pressures in the compression chamber and the suction system, and blocks the oil flow in the oil-supply passage when the pressure differential is overcome by a spring force arranged in the valve chamber.
