Claims

[Claims for Utility Model Registration] 1. A pump housing made up of a cam ring with a cam surface formed on its inner peripheral surface, a front side block and a rear side block joined to both end surfaces of the cam ring, and a pump housing part that is fitted onto a rotating shaft. The rotor is a cylindrical rotor that is rotatably supported in the housing, with vanes inserted into a plurality of slits provided in the radial direction so as to be able to move forward and backward, and the vanes rotate in sliding contact with the cam surface. A compressor mechanism whose main components are housed in a compressor case sealed by a cylindrical case and a front head, and a pump operating chamber formed between the inner peripheral surface of the pump housing and the rotor. A vane type compressor in which the compressor case has an inlet and an outlet that communicate with an inlet and a outlet that are open to the compressor case, the inlet and the outlet being arranged at the rear of the compressor case, A rear suction chamber is provided adjacent to the rear of the rear side block, and the suction port is communicated with the rear suction chamber, and the rear suction chamber beam and the rear suction hole provided in the side block communicate with the suction part of the pump operating chamber. Features a vane type compressor. 2. The communication means between the suction port and the rear suction chamber is such that the peripheral surface of the through hole provided on the back surface of the rear suction chamber and the end surface of the suction port extending into the discharge pressure chamber are joined via a seal. A vane type compressor according to claim 1 of the patented utility model. 3. The means for communicating between the suction port and the rear suction chamber is formed by forming a hole on the back surface of the rear suction chamber and passing through the hole, while extending the suction port into the discharge pressure chamber, and connecting the suction port to the boss. A vane type compressor according to claim 1, characterized in that the outlet portions are fitted and connected via a seal.
