ストン冷却用オイル制御装置。A piston valve, which is always open with a return spring, is inserted in the middle of the piston gear assembly that connects the piston cooling gear assembly with an oil jet and the main gear assembly, and the hydraulic pressure from the main gear assembly is inserted into the operating pressure chamber of this piston valve. An oil control device for cooling a piston of an engine, characterized in that when the oil pressure is high due to the viscosity of the oil, the valve piston is pushed up to close the screws 1 to 3.
