の油冷却装置。 In an oil cooling system for a piston, in which pressure oil discharged from an oil pump is injected from a nozzle to a piston via a check valve that opens when the pressure rises above a set pressure, the check valve senses the temperature of the pressure oil and detects this. A piston oil cooling device characterized in that a spring made of a shape memory alloy is incorporated to open the check valve at the set pressure when the temperature rises above a predetermined temperature.
