Claims

[Scope of utility model registration request]

A rotor that is housed in a cam ring and supports a vane in a manner that allows it to freely protrude and retract; a pair of side plates that sandwich the cam ring and rotatably support a rotating shaft of the rotor that is inserted into a bearing hole of the cam ring; A vane type rotary compressor comprising a back pressure passage defined at the bottom of the slit, and a lubricating oil passage for introducing lubricating oil into the back pressure passage through the bearing hole, A disc-shaped member having a through hole is inserted, and a movable piece is attached to the inner plate-shaped member to define an annular passage communicating with the through-hole between the disc-shaped member and the movable piece. A vane-type rotary compressor characterized in that the movable piece is deformed according to oil pressure to make the flow passage cross-sectional area of the annular passage variable.
