Claims

[Scope of utility model registration request]

(1) In a rotary compressor equipped with a rotary sleeve rotatably supported within a center housing, a rotor rotating at an eccentric position within the rotary sleeve, and a vane fitted to the rotor so as to be movable forward and backward, the housings on both sides An annular passage communicating from a discharge chamber to a pressurized gas chamber between the center housing and the rotating sleeve through a discharge hole and a discharge valve provided on at least one of the housings is provided between one of the housings on both sides and the center housing. The pressurized gas chamber is provided with an exhaust port communicating with the atmosphere or the suction chamber, so that the center housing is provided with an exhaust port that communicates with the center housing the static pressure of the pressurized gas chamber and the dynamic pressure of the gas flowing into the pressurized gas chamber from the annular passage. A rotary compressor characterized in that the rotary sleeve is supported by.

(2) The rotary compressor according to claim 1, which is a registered utility model, characterized in that an annular side seal ring is interposed between the rotary sleeve and the housings on both sides.

(3) A device characterized in that the discharge chamber and the annular passage communicate with each other via a check valve that opens toward the annular passage.
- A rotary compressor according to claim 1 of the patent registration claim.

(4) The rotary compressor according to claim 1, which has been registered as a utility model, and is characterized in that annular guide rings are provided at both ends in the axial direction between the center housing and the rotary sleeve.
