Abstract
A variable displacement compressor includes a housing assembly. A displacement control structure for the variable displacement compressor includes a passage forming member, a flat partition and a displacement control valve. The passage forming member is connected to an exterior surface of the housing assembly for forming a refrigerant passage for allowing the refrigerant to be discharged out from the compressor to an external refrigerant circuit. The flat partition is interposed between the passage forming member and the housing assembly. A throttle penetrates through the partition, which divides the refrigerant passage into an upstream passage and a downstream passage. The displacement control valve is provided in the passage forming member. The displacement control valve senses pressure of refrigerant in the upstream passage and pressure of the refrigerant in the downstream passage to control flow rate of the refrigerant flowing through a supply passage.
