圧縮機。A piston that eccentrically rotates inside a cylinder by a crankshaft.
A vane contacts the outer periphery of the piston and slides in a groove formed in the cylinder by rotation of the piston, and a compression device that divides the inside of the cylinder into a high pressure chamber 4 and a low pressure chamber and performs compression. A rotary compressor housed in a closed container serving as a high-pressure space, characterized in that the inner pipe press-fitted into the suction hole that guides gas into the cylinder chamber is composed of a pipe with a multilayer structure of two or more layers. Rotary compressor.
