Claims

[Scope of utility model registration request]

A piston that is slidably installed in a cylinder hole formed in a compressor body and that includes a head and a rond part, and a compression helical spring that is installed inscribed in the head of the piston and the bottom surface of the cylinder hole. In the piston device for a compressor, which includes a moving member screwed onto the protruding end of the rond portion of the piston, a notch having a sloped portion is formed on the inner surface of the head of the piston, and the sloped portion is formed in the notch. attaching an elastic member having a groove, forming a groove on a relative surface of the slope portion and the slope portion;
A pin formed protruding from the end face of the compression helical spring is fitted into this groove, and the pin is configured to apply rotational force to the piston when the compression helical spring is compressed and deformed, A piston device for a compressor, characterized in that the direction of rotation thereof coincides with the direction in which the tip of the rond portion is tightened to the moving member.
