Abstract: A variable displacement compressor controls a discharge displacement by changing an inclination of a swash plate (5) depending on a pressure differential between a crank chamber (3) and a suction chamber (13) thereby to change a piston stroke. A first communication passage (18) establishes communication between the crank chamber and the suction chamber. A first orifice (19) is provided in the first communication passage. A second communication passage (20) establishes communication between a discharge chamber (14) and the crank chamber. A pressure control valve (21) open/close controls the second communication passage so as to adjust a pressure in the crank chamber. A third communication passage (22) establishes communication between the discharge chamber and the crank chamber, bypassing the second communication passage. A second orifice (23) is provided in the third communication passage.

Abstract: A slant plate type compressor having a capacity or displacement adjusting mechanism includes a housing for a cylinder block provided with a plurality of cylinders and a crank chamber. A piston is slidably fitted within each of the cylinders and is reciprocated by a drive mechanism which includes a slant plate having a surface with an adjustable incline angle. The incline angle of the slant plate, and thus the capacity of the compressor, is controlled according to the pressure differential between the crank chamber and the suction chamber. The pressure in the suction chamber is controlled by a valve control mechanism which is disposed in a passageway linking the crank chamber and the suction chamber. An internally controlled safety valve device prevents an abnormal pressure differential between the crank and suction chambers. The internally controlled safety valve device is provided within the valve control mechanism, thereby obtaining an easily manufactured slant plate type compressor having a durable and reliable capacity adjusting mechanism with a safety valve device.

Abstract: Overpressure of refrigerant in a refrigerant circuit is avoided. A swash plate type variable displacement compressor includes a muffler (muffler space 123) at the top of a cylinder block 101 thereof. The muffler space 123 is connected to a communication passage communicating with a discharge chamber of the compressor, and in this connecting portion, a check valve 200 for suppressing a backflow of the refrigerant is provided. The muffler space 123 communicates with a discharge-side external refrigerant circuit via a discharge port. An inlet port of the high-pressure relief valve 250 in the muffler space 123 communicates with the muffler space 123 located on downstream side of the check valve 200, and an outlet port thereof communicates with a crank chamber 105 of the compressor through communication passages 101c and 101d of the cylinder block 101. The crank chamber 105 communicates with a suction chamber of the compressor through a gas bleeding passage. The high-pressure relief valve 250 is opened when pressure in the muffler space 123 increases to overpressure to flow refrigerant at a high pressure into the crank space 105 from the muffler space 123 through the communication chambers 101c and 101d.
