Claims

[Claims for Utility Model Registration] (1) A cylinder whose both sides are closed by a housing having a bearing portion, and a rotating shaft that is supported by the bearing portion of the housing and has an eccentric portion in the middle of rotation within the cylinder. a rolling piston that fits into the eccentric portion of the rotating shaft and rotates along the inner circumferential wall of the cylinder; a compression chamber formed between the rolling piston and the cylinder; a vane that presses the outer periphery of the rolling piston from the radial direction, a suction hole that communicates with the high pressure side of the compression chamber via a suction passage, and a suction hole that communicates with the high pressure side of the compression chamber through a suction passage. In a refrigerant compressor, the refrigerant compressor includes a discharge hole that communicates with the discharge hole through a discharge path, a valve support disposed inside the discharge hole, and a valve plate that opens and closes the inlet of the discharge hole, the valve plate being on the valve support side. The valve plate A and the valve plate B on the side opposite to the valve support are stacked so as to be separable, and the valve plate B has a hole smaller than the diameter of the discharge path at the entrance of the discharge hole. A refrigerant compressor characterized by: (2) The refrigerant compressor according to claim 1, wherein the thickness of the valve plate A is not thicker than the thickness of the valve plate B.
