Claims

[Scope of utility model registration request]

A rotor is rotatably provided in a cam ring whose end opening is closed by a front plate and a retainer plate, and a plurality of slits are formed in a substantially radial direction within the rotor, and lubricating oil is communicated with each of these slits. A vane-type rotary compressor is provided with a back pressure passage filled with An oil passage is provided in the rotor, one end of which opens on the sliding surface of the vane which is the back surface according to the rotational direction of the rotor, and the other end communicates with the back pressure passage, and the oil passage can be opened and closed by the movement of the vane into and out. A vane type rotary compressor featuring:
