description The utility model discloses a piston of a cold compressor. The piston is provided with an outer diametral plane for being contacted with a piston hole of the compressor. In order to keep good sliding performance between the piston and the piston hole, the outer diametral plane is coated with polyfluortetraethylene film, thus avoiding clamping stagnation between the piston and the piton hole. The utility model further provides a cold compressor with the piston.
