摘要： A single headed swash plate type compressor including, a housing with a crank chamber and cylinder bore, pistons arranged in cylinder bores, and a swash plate driven by a drive shaft. Each of the pistons has at one end thereof a bearing having axially spaced first and second bearing portions and an axially extending third portion interconnecting the first and second bearing portions. Shoes are slidably arranged between the swash plate and the first and second bearing portions for converting rotational movement of the swash plate into reciprocal movement of the pistons. An oil communication hole is arranged in and extends through the second bearing portion for fluid communication between the groove of the second bearing portion on the side remote from the cylinder bore and the crank chamber.

摘要： A variable displacement compressor comprising a cylinder block having a plurality of cylinder bores. The cylinder block has an extension which extends from an outer periphery of an end surface of the cylinder block which faces a swash plate. The extension has an extension surface which forms a part of a bore surface of each cylinder bore and first and second wall surfaces which extend continuously from opposite ends of the extension surface in a circumferential direction of the extension surface. A part of each extension surface which is connected to the first wall surface which is located on a preceding side of rotation of the swash plate corresponds to a high-load area which is locally subjected to loads from a single-headed piston during a compression stroke. The high-load area has a chamfered region which is formed into a curved surface by chamfering.

摘要： A compressor includes a compressing mechanism for compressing refrigerant gas and an oil separator for separating the oil from the gas. The separated oil is used to lubricate the compressor. The compressor has a discharge passage to permit refrigerant gas to flow out of the compressor, a recess located in the discharge passage, a plug press fitted in the recess and a supply passage for returning the separated oil to the compressor. The plug and the recess define a separation chamber having a circular cross-section and an annular chamber. The separation chamber is connected with the annular chamber by an outlet passage formed in the plug. The refrigerant gas swirls along the wall of the separation chamber, which separates the oil from the gas. Since the plug is press fitted in the recess, installation of the plug is facilitated. This structure also prevents the plug from loosening.

摘要： The present invention relates to a structure for separating oil from a refrigerant gas containing the oil. The refrigerant gas is discharged from a refrigerant compressor which forms a part of refrigerating cycle to an external refrigerant circuit. The oil separation structure includes a separation chamber in which the oil is separated from the discharge refrigerant gas having a cylindrical inner surface, and a plurality of introduction passages through which the discharge refrigerant gas is introduced into the separation chamber. The oil is separated by centrifugal action from the discharge refrigerant gas by turning the discharge refrigerant gas introduced into the separation chamber along the cylindrical inner surface.

摘要： A variable displacement type swash plate compressor that prevents a drive shaft from moving axially when the difference between a crank chamber pressure and a cylinder bore pressure becomes excessive. A hinge mechanism has a support arm extending from a lug plate and a guide pin extends from a swash plate. The head portion of the guide pin fits in a guide hole formed in the support arm. A cutaway surface is formed in a part of the support arm that defines the guide hole. The cutaway surface forms a clearance in the hinge. The clearance permits the swash plate to move without pulling the drive shaft.

摘要： A variable displacement compressor includes a rotor, which is fixed to a drive shaft, and a pivotal swash plate, which is supported on the drive shaft and slides in an axial direction along the drive shaft. A hinge mechanism is located between the rotor and the swash plate. The hinge mechanism rotates the swash plate integrally with the rotor and guides the pivoting and the sliding motion of the swash plate. The hinge mechanism includes a swing arm, which extends from the swash plate. The swash plate is made of aluminum or aluminum alloy material. The swing arm is separate from the swash plate and is made of iron-based metal material. Therefore, while the swash plate is light, the hinge mechanism is strong.

摘要： A reciprocating piston type compressor for compressing refrigerant gas for an automobile air conditioning system is improved to protect itself without protective control by a computer. The compressor detects the temperature of a part of the compressor in which the temperature increases to higher than a predetermined critical temperature when the compressor malfunctions, and changes a displacement control valve to reduce the displacement of the compressor when the detected temperature is higher than the predetermined critical temperature.
