関のピストン装置。 In a piston device for a reciprocating internal combustion engine having a first pressure ring and a second pressure ring, the abutment gap of the second pressure ring is set narrower than the abutment gap of the first pressure ring, and
A communication hole is provided that communicates the outer peripheral space of the piston second land between the pressure ring and the inner space of the piston, and the second land is provided on the piston inner space side of the communication hole when the temperature of the piston is lower than a set temperature. A reciprocating motion characterized by being provided with a temperature-sensitive check valve that allows fluid to flow only from the outer peripheral side space to the piston inner space of the communication hole, and opens the communication hole in both directions when the temperature is higher than a set temperature. Piston device of internal combustion engine.
