Claims

[Scope of utility model registration request]

In a piston ring that is inserted into a ring groove of a piston of a reciprocating engine such as an internal combustion engine and slides on the inner surface of the cylinder,
A communication hole is provided between the upper surface and the lower surface of the piston ring, and the lower opening of the communication hole communicates with the lower land gap of the piston ring and extends from the lower opening to the upper opening above the upper opening. A ring mechanism for a piston, characterized in that a check valve is disposed to allow only the flow of fluid toward the piston, and a notch is provided at a lower portion of the piston ring or near the lower opening of the ring groove.
