PCT No. PCT/JP82/00436 Sec. 371 Date Jul. 11, 1983 Sec. 102(e) Date Jul. 11, 1983 PCT Filed Nov. 10, 1982 PCT Pub. No. WO83/01818 PCT Pub. Date May 26, 1983.A compressor of the present invention performs restraining action in refrigerative ability at high speed driving time utilizing suction loss that vane chamber pressure drops lower than supply source pressure of refrigerant, and comprises a rotor (14) having vanes provided slidably, a cylinder (11) receiving said rotor (14) and vanes (12), side plates fixed to both side faces of said cylinder (11) and closing tightly a space of vane chamber (18a), (18b) formed by said vanes (12), rotor (14) and cylinder (11) at its side faces, and at least more than two suction ports (15) and (17), whereby even in a compressor having many numbers of vane (12), such a compressor with ability control that having no loss in refrigerative ability at low speed, and refrigerative ability is restrained only at high speed driving can be realized.
