変容量式回転型圧縮機。[Claims for Utility Model Registration] (1) A rotor having a plurality of vanes is rotatably provided in a rotor chamber formed by a cylinder and a side plate joined to the open end surface of the cylinder, and the side plate A rotary valve for variable capacity is rotatably arranged opposite the axial end face of the rotor, and the rotary valve and side plate are always connected to a suction chamber and a compression chamber with a maximum effective passage area. When the rotary valve rotates in the same direction as the rotation direction of the rotor, the intake port reduces the amount of intake gas by narrowing the effective passage area, and the intake port is always kept in a disconnected state.
The variable displacement rotary compressor is provided with a bypass port that communicates the compression chamber with the suction chamber and releases a part of the compressed gas to the suction chamber when the rotary valve rotates in the same direction as the rotational direction of the rotor. The vane is made of iron-based material, the rotary valve is made of aluminum, and at least the periphery of the side facing the vane of the bypass port formed in the rotary valve is made of the same or the same hard material as the vane. Capacitive rotary compressor. (2) The variable displacement rotary compressor according to claim 1, which is a utility model and has a structure in which a flanged bush for forming the bypass port is cast into a rotary valve.
