摘要： A compressor includes a piston and a shoe, which contact and slide on one another. The piston includes a sliding surface, on which a solid lubricant film is formed. The shoe includes a sliding surface that slides on the first sliding surface. A soft film that mainly contains soft metal is formed on the second sliding surface. The solid lubricant that forms the solid lubricant film is a solid lubricant other than a soft metal.

摘要： A variable displacement compressor has a housing, which defines a crank chamber, a suction chamber, and a discharge chamber. A bleed passage connects the crank chamber to the suction chamber, which allows gas to flow from the crank chamber to the suction chamber. A release valve, which is a reed valve, is located in the bleed passage. The release valve varies the opening of the bleed passage in accordance with the difference between the pressure in the crank chamber and the pressure in the suction chamber. This can prevent the pressure in the crank chamber from excessively increasing.

摘要： A variable displacement type refrigerant compressor including a compressor housing having internally a compressing mechanism for compressing a refrigerant, a displacement varying mechanism for adjustably varying an amount of the refrigerant compressed and discharged by the compressing mechanism, and a displacement control valve unit controlling the operation of the displacement varying mechanism, which is an assembly of a pressure sensing mechanism formed by a flanged bellows element, a valve element, a valve seat having a port cooperating with the valve element, and a valve rod engaging the pressure sensing mechanism with the valve element, and are assembled by using a fixing screw member and a jig tool in position in a pressure sensing chamber, a valve chamber, and a valve rod bore coaxially formed in the compressor housing by drilling or boring from two sides of the compressor housing. The flanged bellows element of the displacement control valve unit is fixed in the pressure sensing chamber via the flange thereof by being threadedly engaged in the pressure sensing chamber.

摘要： A control valve varies the displacement of a variable displacement compressor. A pressure chamber is connected to a suction chamber through a fixed throttle and to a discharge chamber through an intake passage. The intake passage includes a fixed throttle and an electromagnetic valve. A controller controls the electromagnetic valve in accordance with data related to the running conditions of the vehicle. The control valve has a threshold value that changes in accordance with the opening and closing of the electromagnetic valve.

摘要： A variable displacement compressor has a housing, which defines a crank chamber, a suction chamber, and a discharge chamber. A release passage connects the crank chamber to the suction chamber, which allows gas to flow from the crank chamber to the suction chamber. A release valve is located in the release passage. The release valve regulates gas flow in the release passage. A controller controls the release valve to limit the pressure in the crank chamber to prevent the pressure in the crank chamber from becoming undesirably high. This can prevent the pressure in the crank chamber from excessively increasing.
