Claims

[Claims for Utility Model Registration] 1. A rotor equipped with vanes is housed in a chamber consisting of a cylinder and side plates provided on both sides of the cylinder, and as the rotor rotates, a compression chamber expands or contracts to exert a compression effect. In vane-type compressors that perform A vane type compressor, characterized in that a high pressure groove is provided on the other side plate to guide high pressure to the vane pressure chamber, and further, at the end of the compression stroke, the vane pressure chamber is separated from the high pressure groove to form a closed chamber. Vane extrusion device. 2. The scope of the utility model registration claim No. 2 is characterized in that the position of the high pressure groove is set so that the vane pressure chamber is closed at the beginning of the compression stroke, and the vane pressure chamber communicates with the high pressure groove at the middle stage of the compression stroke. A vane extrusion device for a vane compressor according to item 1. 3. A vane extrusion device for a vane type compressor according to claim 1, which is configured so that an intermediate pressure between the suction pressure and the discharge pressure acts on the low pressure groove during the suction stroke.
