Claims

[Scope of utility model registration request]

A cam ring and a rotor, which is rotatable within the cam ring by providing a plurality of vanes inscribed in the cam ring so as to be movable in the radial direction, are eccentrically arranged in the housing,
A sealing member is housed in an annular groove provided on one side of the cam ring to provide a seal between the cam ring and the housing;
In a rotary vane pump having a suction port and a discharge port in contact with the other side of the cam ring, in a region corresponding to the suction port of the cam ring, a side surface of the cam ring provided with the annular groove extends radially from the annular groove to both sides. A rotary vane pump characterized by a drain groove.
