摘要： A piston type compressor comprises a cylinder block having a plurality of cylinder bores, a plurality of pistons disposed in the respective cylinder bores for defining compression chambers in the respective cylinder bores, a housing for defining a suction-pressure region and a discharge-pressure region therein, a valve-port assembly provided between the cylinder block and the housing, and a seal member provided between the cylinder block and the housing. The seal member has a first seal portion for preventing the refrigerant from leaking out of the compressor and a second seal portion for preventing the refrigerant from leaking between adjacent refrigerant passages. Each of the first and second seal portions has a bead. The bead of the second seal portion has a height which is smaller than that of the first seal portion.

摘要： A piston compressor in which carbon dioxide is used as a refrigerant is provided. The compressor includes a cylinder block, reciprocating pistons, a valve plate, a housing member, and sealing members. The cylinder block has an end face and a plurality of cylinder bores. The pistons are housed in the individual cylinder bores. The valve plate has a plurality of discharge ports. The housing member is fixed to the end face of the cylinder block with the valve plate in between. The housing member has a partition wall. The housing member and the valve plate define a suction chamber and a discharge chamber. The discharge chamber is connected to the cylinder bores through the corresponding discharge ports. The suction chamber and the discharge chamber are partitioned by the partition wall. The sealing members each are interposed between the valve plate and the cylinder block, and between the valve plate and the housing. A value of a ratio of the thickness of the valve plate relative to a diameter of each cylinder bore is between 0.13 and 0.4, inclusive.

摘要： The variable displacement compressor has a suction-pressure region, a discharge-pressure region and a crank chamber. The compressor includes a supply passage, a bleed passage and a control valve that adjusts cross-sectional area of the bleed passage. The control valve includes a valve chamber, a valve portion and a valve seat member. The valve portion is disposed in the valve chamber for dividing the valve chamber into a bleed chamber, a backpressure chamber and a communication passage. The bleed chamber forms a part of the bleed passage. The backpressure chamber communicates with the supply passage. The communication passage is formed between an outer circumferential surface of the valve portion and an inner circumferential surface of the valve chamber for providing fluid communication between the bleed chamber and the backpressure chamber. The valve seat member is disposed in the bleed chamber and provided separately from a compressor housing forming the valve chamber.
