Abstract

PURPOSE:To raise the efficiency of a dynamic seal, by forming a dynamic seal section consisting of a pattern of grooves having a small depth at the suction side of a side plate so as to exert the function of dynamic seal effectively, and reducing the amount of leaked fluid by omitting the grooves of the dynamic seal section at the discharge side of the side plate. CONSTITUTION:Leakage of fluid Qc from a ring-like groove 56 to a low-pressure vane chamber 52 is prevented by a dynamic seal section 57 consisting of spiral grooves. The dynamic seal section 57 is formed as a pattern of grooves having a small depth that are formed in a side plate 53 at its suction side in the manner that the gap to the relative sliding surface of vanes 53 is changed. That is, the function of dynamic seal is exerted effectively since the leaked fluid Qc is a viscous fluid consisting of oil admixed with a cooling medium. At the discharge side of the side plate 53, on the other hand, the amount QA of leaked fluid can be rather reduced by omitting the grooves since the leaked fluid QA is almost in the state of gas.
