摘要： A shaft sealing assembly is located in a suction chamber of a swash plate type compressor to seal the space between a drive shaft and a housing. A first end portion of the drive shaft is supported by a first radial bearing. A second end portion of the drive shaft is supported by a second radial bearing. The suction chamber is closer to the first end portion of the drive shaft than the first radial bearing is. An axial passage is formed in the drive shaft to connect the suction chamber to the crank chamber. An inlet of the axial passage is closer to the second end portion than the second radial bearing is. An outlet of the axial passage is closer to the second end portion than the first radial bearing is.

摘要： A piston type variable displacement fluid machine includes a drive shaft and a cylinder bore. A piston reciprocates along a line of movement in the cylinder bore in accordance with the rotation of the drive shaft. The stroke of the piston is varied between the maximum stroke and the minimum stroke, which is greater than zero. The displacement of the fluid machine is changed in accordance with the stroke of the piston. A ring groove is formed on the outer circumferential surface of the piston. A piston ring is fitted in the ring groove and moves with respect to the piston in the line of movement of the piston. An allowable movement amount of the piston ring with respect to the piston is greater than or equal to the minimum stroke of the piston.

A drive shaft passes through the suction chamber and extends from a front end of a housing. The drive shaft is supported by the housing. A shaft sealing assembly for sealing the drive shaft is located in the suction chamber. In the cylinder block and a valve plate, a bleed passage is formed for connecting the crank chamber with the suction chamber. The bleed passage is inclined downward toward the suction chamber. The outlet of the bleed passage is above the shaft sealing assembly. In the suction chamber, a reservoir, which stores lubricating oil supplied through the bleed passage, is surrounds a lower part of the shaft sealing assembly.

摘要： In a single-ended swash plate compressor, unbalanced thrust loads in either axial direction are reduced so that thrust loads acting on pistons in the direction of the front end are practically balanced by those in the direction of the rear end, for example, by connecting an intake chamber to a swash plate chamber by means of an adjustment valve to adjust the pressure in the swash plate chamber acting on the front end surfaces of the pistons to a suitable intermediate pressure by the action of the adjustment valve. In a single-ended swash plate compressor with pistons housed in both ends of a cylinder assembly comprising one set of pistons for guidance and another set for compression, discharge pressure is introduced into some of the cylinder bores housing guide pistons and intake pressure is introduced into the cylinder bores housing guide pistons into which discharge pressure is not introduced.

摘要： A control valve is used for a variable displacement compressor installed in a refrigerant circuit of a vehicle air conditioner. The control valve has a valve housing. A valve chamber is defined in the valve housing. A valve body is accommodated in the valve chamber. A pressure sensing chamber is defined in the valve housing. A pressure sensing member separates the pressure sensing chamber into a first pressure chamber and a second pressure chamber. The pressure at a first location in the refrigerant circuit is applied to the first pressure chamber. The pressure at a second location in the refrigerant circuit, which is downstream of the first location, is applied to the second pressure chamber. The pressure sensing member moves the valve body in accordance with the pressure difference between the first pressure chamber and the second pressure chamber such that the displacement of the compressor is varied to counter changes of the pressure difference. At least one of the first pressure chamber and the second pressure chamber forms a part of the refrigerant circuit.

摘要： A variable displacement compressor in a refrigeration circuit using carbon dioxide refrigerant. The compressor changes the inclination of a swash plate located in a control chamber in accordance with the difference between the pressure in the control chamber and the pressure in a suction chamber thereby varying the compressor displacement. The compressor includes a control valve that adjusts the difference between the pressure in the control chamber and the pressure in the suction pressure. The control valve controls the flow rate of refrigerant supplied from the discharge chamber to the control chamber thereby adjusting the pressure difference. A controller inputs information from the outside of the refrigeration circuit. The outside information includes the outside temperature, the temperature of a passenger compartment and a target compartment temperature set by a temperature adjuster. The controller sets a target value of the pressure of refrigerant discharged from the compressor in accordance with the outside information. The controller then controls the current supplied to the control valve such that the target discharge pressure is rapidly reached. The compressor reduces unnecessary operation thereby reducing the power consumption and the load.
