Claims

[Claims for Utility Model Registration] (1) In a rotary compressor with a closed structure in which the operating capacity of the compressor is controlled by a capacity control mechanism provided on the side wall of the cylinder that forms the compression chamber, a release that opens into the compression chamber a hole, a valve storage hole provided on the back of the release hole, a valve storage member placed in the valve storage hole and also serving as a valve seat, a release valve stored in the valve storage member, and the valve storage hole. A valve stopper provided on the back of the member to regulate the stroke of the release valve; and a valve stopper provided on the back of the valve stopper to fix the valve storage member and the valve stopper and to serve as a flow path for the released gas. A capacity control mechanism for a rotary compressor, comprising a substantially cylindrical joint member that guides the gas to the outside of the compressor and has a joint function with a release pipe. (2) The capacity control mechanism for a rotary compressor according to claim 1, wherein a corrugated washer is provided between the valve stopper and the substantially cylindrical connecting member. (3) Utility model registration claim 1, characterized in that the hardness of the valve housing member is set to be less than the hardness of the release valve and more than the hardness of the cylinder.
Capacity control mechanism of the rotary compressor described in 2.
