けるチヤタリング防止構造。 A cylinder block formed into a hollow cylindrical shape,
A compression chamber exists in the sealed space formed by the front and rear side plates that cover both the front and rear openings of the cylinder block, and the rotor is rotatably mounted on the shaft, and vane grooves are carved in the rotor. The vane groove has a back pressure chamber into which the vane can be inserted and retracted, and the side plate has a pressure groove carved in an arc shape corresponding to the back pressure chamber to separate the pressure groove. In a compressor, the compressor is provided in communication with a lubricating oil reservoir formed at the bottom of the chamber, and the compression capacity in the compression chamber is controllable in response to changes in cooling load, wherein the pressure groove and the separation chamber or An auxiliary pressure hole is provided to communicate between the discharge chambers, and a valve is provided in the auxiliary pressure hole so that it can be opened and closed freely.The valve is connected between the discharge pressure in the discharge chamber or separation chamber and the pressure in the back pressure chamber. A structure for preventing chattering in a slide vane rotary compressor, which is configured to open and close based on changes in the differential pressure that occurs.
