Claims

[Claims for Utility Model Registration] A rolling piston attached to a piston shaft in a cylinder chamber is rotated eccentrically, and the volume of the suction chamber and compression chamber partitioned by the minimum gap between the rolling piston and the cylinder and the vane is A rotary compressor that sucks in and compresses gas by increasing or decreasing, and in which a rolling piston is movably mounted with a gap formed between the piston shaft and the piston shaft.
A high-pressure gas supply means for supplying high-pressure gas into the gap and an elastic means inserted into the gap are provided, and the rolling piston is fixed to the piston shaft by the high-pressure gas in the gap and the elastic force of the elastic means. On the other hand, the rotary compression is characterized in that the pressure in the compression chamber is configured such that the rolling piston is movable so as to widen a minimum gap between the rolling piston and the cylinder, which are fixed by the high pressure gas and elastic force.
