Abstract: PROBLEM TO BE SOLVED: To provide an air conditioner and an air compressor used for it, suitable for high performance of equipment, saving motive power, and reducing a cost.
SOLUTION: A high pressure air pipe 16 connects a discharge valve chamber 13 side of an air compressor 1 with an oil separator 2 side. A discharge valve chamber 13 of the air compressor 1 discharges high pressure refrigerant gas containing oil to the oil separator 2 side through the high pressure air pipe 16 directly to separate oil content from the high pressure refrigerant gas only by the oil separator 2. An oil return pipe 38 connects an oil reservoir 36 in the oil separator 2 with an oil supply port 37 of the air compressor 1 to directly return the oil from oil reservoir 36 in the oil separator 2 to the oil supply port 37 of the air compressor 1 through the oil return pipe 38.

Abstract: PROBLEM TO BE SOLVED: To inhibit chattering by quickly raising vane back pressure immediately after a start of a gas compressor.
SOLUTION: Refrigerator oil R reaching a bearing 22 through a high pressure passage 23a is led to the end surface 50a of a rotor 50 while reducing the pressure thereof by a restriction part 22b which is a gap between the inner circumference surface 24a of a bearing member 24 formed of FRP and the outer circumference surface 51a of a rotary shaft 51 (distance r2 (>r1)). Pressure loosing action at the restriction part 22b by a restriction member 24 to the refrigerator oil R is reduced as compared to that of a former gas compressor by leading the refrigerator oil R to the end surface 50a of the rotor 50 while reducing the pressure thereof. The pressure of the refrigerator oil R introduced to a flat groove 25 through the restriction part 22b is kept higher than the pressure of the refrigerator oil R introduced to the flat groove 25 in the former gas compressor, and chattering caused by the insufficient back pressure of the vane 58 during the start of a compressor 100 can be inhibited.
