気密的に圧接させたことを特徴とする圧縮機。 A pump housing is formed by fixing a front side block to one end of a cam ring having a cam circumferential surface on its inner surface and a rear side block to the other end, and a rotor supported by a rotating shaft is provided within the pump housing. At the same time, a vane is slidably inserted in a plurality of vane grooves formed in the rotor along the radial direction so as to be able to protrude and retract from the outer peripheral surface of the rotor, and as the rotor rotates, the tip of the vane is brought into sliding contact with the cam ring. In a compressor that performs a pumping action, annular recesses are formed in the inner wall surfaces of the front side block and the rear side block, and the diameter of the outer peripheral edge of the recess is such that the tip of the vane is inward from the outer peripheral surface of the rotor. The distance between the tip of the vane and the center of the rotor in the maximum retracted state is set to a value slightly smaller than the diameter and as close as possible to the diameter, and an annular seal plate is installed in these recesses. A compressor characterized in that these seal plates are fitted together and are brought into airtight pressure contact with both end surfaces of the rotor by the elastic force of an elastic member.
