Claims

[Scope of utility model registration request]

A cam ring consists of a substantially elliptical cylinder whose ends are sealed by a pair of side plates, and in which a suction port and a discharge port are formed. a rotor made of a cylindrical body for holding the vane so as to be freely displaceable in the radial direction, the vane defining a back pressure passage on the radially inner end side of the slit 1;
In a vane-type rotary compressor, in which lubricating oil is introduced into the back pressure passage and the vane is made to protrude from the slit, and a pump chamber whose volume is variable is defined by the vane, after the vane has passed the maximum stroke position. A high-pressure groove for introducing high-pressure lubricating oil into the back pressure passage is installed in the section from an arbitrary position to a position where a minimum clearance is formed between the vane, the outer circumferential surface of the rotor, and the inner circumferential surface of the cam ring. is provided on the side plate, and after the vane passes through the minimum clearance position, lubricating oil of lower pressure than the high pressure lubricating oil is introduced into the back pressure passage in a section where the back pressure passage does not communicate with the high pressure groove. A vane type rotary compressor that is characterized by:
