るオイルリリーフ。An oil relief valve attached to a return passage branching into an oil pan from the oil pump discharge passage of an internal combustion engine includes a cylinder whose upper end is fixed and communicated with the oil pump discharge passage, and a cylinder that slides up and down into the cylinder. The piston valve is composed of a freely fitted piston valve and an elastic member that urges the piston valve downward, and the piston valve is formed with a pressure receiving surface that receives the oil pressure in the return passage from below. An oil relief characterized in that the cylinder or the piston valve is provided with a discharge communication portion that is closed at a lower position of the valve and opened at an upper position of the piston valve.
