Claims

[Claims for Utility Model Registration] 1. A front side plate and a rear side plate are joined and fixed to both open end surfaces of an elliptical cylinder, and a vane is provided in the cylinder bore of the cylinder to be rotated by a rotating shaft. A rotor is housed in such a manner that its outer circumferential surface is in close proximity to two minor diameter portions of the cylinder bore, and the cylinder and both side plates are enclosed by a front housing forming a suction chamber and a rear housing forming a discharge chamber. The front side plate is provided with a through hole that communicates the suction chamber with the compression chamber in the cylinder bore, the cylinder is provided with a discharge port that communicates the compression chamber with the discharge chamber, and the rear side of the front side plate is and a front end surface of the cylinder, a rotating plate having an annular shape is provided between the through hole and the front end surface of the cylinder to control the suction amount of refrigerant gas supplied from the through hole to the compression chamber during the suction stroke. In the variable capacity vane compressor, the variable capacity vane compressor is configured such that a flange portion provided on the front side of the recess for forming the discharge chamber formed in the cylinder is connected to the rear side surface of the front side plate by a connecting means. type vane compressor. 2. The variable displacement vane compressor according to claim 1, wherein the connecting means is a connecting bolt or a connecting pin.
