てなる回転圧縮機。 A cylinder having a space inside thereof, and a suction port and a discharge port provided at appropriate positions on the circumferential wall of the space;
a rotor that is rotatably provided within the space and has its peripheral wall surface in contact with the peripheral wall of the space at a proper location to form a compression chamber in the space that extends from the suction port to the discharge port; A vane that is always in pressure contact with the circumferential wall of the space, and a discharge valve device that opens a discharge port when the pressure in the compression chamber reaches a predetermined pressure are provided, and the circumferential wall of the space and the rotor circumferential wall are connected to each other in the rotational direction of the rotor. The compression chamber is brought close to each other between the suction port and the discharge port to narrow it, and at this close portion, the rate of change in the compression chamber volume with respect to the rotor rotation angle is close to 0 (dV/dQ≒0
), and in a rotary compressor configured so that the pressure in the compression chamber reaches a predetermined pressure when the vane reaches the approach section, compression chambers of the same shape are placed at opposite positions inside the cylinder. A rotary compressor characterized in that a plurality of vanes are provided and a plurality of vanes are provided at opposing positions on the outer peripheral wall of a rotor so that they can appear and retract.
