Claims

[Scope of utility model registration request]

(1) A piston mechanism consisting of a cylinder and a piston formed to be able to reciprocate with respect to the cylinder via a seal ring mechanism and equipped with a connecting rod connected by a piston pin, A passage passing through in the axial direction is provided, and a check valve mechanism is provided on the piston top end surface side of the passage for communicating between the cylinder head side and the rod side of the piston via the passage during the piston withdrawal cycle. A piston mechanism applied to near compressors etc. characterized by the following.

(2) The seal ring mechanism provided on the outer periphery of the piston is characterized in that a seal ring member is disposed in a groove formed on the outer periphery of the piston with an O-ring member interposed therebetween. A piston mechanism applied to a near compressor according to claim (1) of the utility model registration.

(3) The means for preventing axial movement of the piston pin with respect to the piston comprises a retaining ring member attached to a groove provided on the outer periphery of the piston with respect to the mounting position of the piston pin. A piston' mechanism applied to a near compressor according to claim (1) of the utility model registration.
