Title:
GAS COMPRESSOR
Document Type and Number:
WIPO Patent Application WO/2013/077388
Kind Code:
A1
Abstract:
A gas compressor is provided with a cylinder member (40), a rotor (50), and vanes (58). A proximity section (48) is provided between the cylinder member (40) and the rotor (50), and this forms a single cylinder chamber (42) for performing only one cycle of compression of a refrigerant gas (G) per rotation of the rotor (50). At least one auxiliary discharge section (46) is provided upstream of a discharge section (45). When the pressure of the refrigerant gas (G) within a compression chamber (43) reaches a discharge pressure (P), the auxiliary discharge section (46) releases the pressure within the compression chamber (43) and maintains the pressure at the discharge pressure (P).
