Claims

[Scope of utility model registration request]

Pressure grooves are carved in the front side plate and rear side plate in correspondence with the rotation locus of the back pressure chamber formed at the bottom of the vane groove extending in the radial direction between the front and rear end surfaces of the rotor. One pressure groove is provided continuously from the opening position of the suction hole to the opening position of the discharge hole, and the other pressure groove is provided continuously from the opening position of the suction hole to the maximum position of the base. A slide vane type rotary compression system that is divided into a pressurizing groove that extends from just before the protruding position to the front, and a pressurizing groove that extends from immediately after the maximum protruding position of the vane to the opening position of the discharge hole. Back pressure applying mechanism on the machine.
