Title:
GAS COMPRESSOR
Document Type and Number:
WIPO Patent Application WO/2013/150967
Kind Code:
A1
Abstract:
A gas compressor wherein the outline shape of the inner circumferential surface (41) of a cylinder (40) is set such that the pressure of a coolant gas (G) in compression chambers (43) reaches discharge pressure at a prior stage (a stage wherein a compression chamber (43B) is located upstream from the angular position at which this compression chamber faces a discharge hole (45b) of a main discharge part (45)), said prior stage being before the stage when, due to the rotation of a rotor (50) in the rotation direction (W), the compression chamber (43B), which is adjacent to and upstream in the rotation direction (W) from a compression chamber (43A), faces the discharge hole (45b) of the main discharge part (45). Thus, the discharge hole (45b) of the main discharge part (45) continually discharges the coolant gas (G) from the compression chambers (43), preventing discharge pulsation.
