Claims

[Scope of utility model registration request]

In a compressor that includes a piston that reciprocates within a cylinder, a piston pin that connects the piston to a connecting rod inserted into a rotating shaft, and a spring pin that fixes the piston pin to the piston, the piston pin is concentric with the piston pin. 1. A piston device for a compressor, characterized in that the piston has holes of the same diameter, and the diameter of the hole on the inlet side is larger than that on the outlet side.
