| description | PURPOSE:To improve the performance of a compressor, by forming a port opened to an inner wall surface of a cylinder chamber into an elongated shape extending in a longitudinal direction of a vane in such a manner as to be registrable with a side surface of the vane. CONSTITUTION:Auxiliary discharge ports 35 and 36 for controlling a discharge quantity and a discharge pressure are opened to an inner wall surface 30 of a cylinder chamber 14. The auxiliary discharge ports 35 and 36 are formed in an elongated shape extending in a longitudinal direction of a vane 5 in such a manner as to be registrable with a side surface of the vane 5. Accordingly, when the vane 5 passes through the auxiliary discharge ports 35 and 36, the vane 5 reliably closes the auxiliary discharge ports 35 and 36 to thereby prevent that a compressed high-pressure gas leaks through the ports 35 and 36 into a compression chamber defined on the rear side in a rotating direction of the vane 5. Therefore, a stable discharge pressure of a refrigerant gas may be obtained to improve the performance of a compressor. |
