    摘要: A variable displacement compressor having a pressurizing passage (55), which extends through a cylinder block (12). The pressurizing passage (55) connects a discharge chamber (39) and a crank chamber (15). A valve (V) is arranged in the pressurizing passage (55). A drive shaft (16) rotates and produces centrifugal force that causes the valve (V) to open the pressurizing passage (55). The pressure of the crank chamber (15) is increased when the rotation of the drive shaft (16) is accelerated thereby opening the pressurizing passage (55) with the valve (V). This moves a swash plate (21) such that its inclination, relative to a plane perpendicular to the drive shaft (16), decreases. As a result, the compressor shifts from a maximum displacement state to a minimum displacement state, which improves the acceleration performance of an engine connected to the compressor. Furthermore, the displacement of the compressor in the minimum displacement state is 50% of that in the maximum displacement state. This prevents an excessive decrease in the cooling capability of the compressor.

    摘要: A variable displacement type compressor is disclosed. The compressor includes a housing, a cylinder bore within the housing, a piston located in the cylinder bore, a drive shaft rotatably supported by the housing, a rotary support mounted on the drive shaft, and a cam plate connected to the piston. The cam plate is supported tiltably on the drive shaft and is slidable in axial directions of the drive shaft. The cam plate inclines between a maximum inclination position and a minimum inclination position when the displacement of the compressor is changed. A first moment is applied to the cam plate by a compression reaction force of the piston when the compressor is operating. A hinge mechanism is located between the rotary support and the cam plate. The cam plate is rotated integrally with the drive shaft, the rotary support, and the hinge mechanism. An urging device is located between the rotary support and the cam plate for urging the cam plate toward the minimum inclination angle position. An applying mechanism applies a second moment to the swash plate in the same direction as the first moment when the compressor is not operating.

    摘要: A compressor housing and method of manufacture and assembly are disclosed. The compressor housing includes a cylinder block (1) and a front housing (2). An annular projection (1a) is formed on the front end of the cylinder block (1). An annular groove (2a) is formed on the rear end of the front housing (2). The cylinder block (1) and the front housing (2) are secured to each other to prevent the front housing (2) from being displaced in relation to the cylinder block (1) by engaging the annular projection (1a) with the annular groove (2a). A gasket (4) is located between the front end of the cylinder block (1) and the rear end of the front housing (2) secured to each other to seal between the cylinder block (1) and the front housing (2). This compressor and its method of manufacture reduce the amount of misalignment between a shaft bore (1b) in the cylinder block (1) and a shaft bore (2b) in the front housing (2), which improves the performance of the compressor.

    摘要: A housing (1, 2, 3) of a compressor has a shutter chamber (13) for accommodating a shutter (21). The shutter (21) moves between a closed position, where the shutter (21) stops flow of gas from an external circuit (35) into a suction chamber (3a), and an open position, where the shutter (21) permits the gas flow in response to the tilting motion of a swash plate (15). A coil spring (24), which has a conical shape, is located in the shutter chamber (13) to bias the shutter (21) in a direction toward the open position from the closed position. The spring (24) is arranged to prevent the spring (24) from sliding against the inner wall of the shutter chamber (13) when the spring (24) is expanded or contracted by movement of the shutter (21).

    摘要: A control valve (50) controls the displacement of a variable displacement type compressor. The compressor includes a crank chamber (5), suction chamber (21), a bleed passage (27), and a supply passage (28). The control valve has a supply side valve (V2), a transmission rod (80), and a relief side valve (V1). The transmission rod (80) connects the relief side valve (V1) with the supply side valve (V2). The relief side valve (V1) includes a passage chamber (53) constituting part of the bleed passage (27). The passage chamber (53) is separated into a first area (53a), which is connected to the crank chamber (5), and a lower area (53b), which is connected to the suction chamber (21). A pressure sensing member (60) moves the relief side valve body (61) in accordance with the pressure in the upper area (53a). The effective pressure receiving area (A) of the sensing member (60) is substantially equal to the cross sectional area (B) of the passage chamber (53) that is sealed by Lhe relief side valve body (61).
