CYLINDER HEAD FOR REDUCING ENGINE NOISE AND PREVENTING DAMAGE OF ENGINE DRIVING COMPONENTS USING CHECK VALVE

摘要

PURPOSE: A cylinder head for reducing engine noise and preventing the damage of an engine driving component is provided to remain a certain amount of engine oil in the cylinder head using the check valve even when the engine is not driven, thereby minimizing the engine noise and preventing the damage of the engine driving component. CONSTITUTION: An oil fan stores engine oil. An oil pump(200) sends the engine oil to the respective driving components. An oil return passage(600) returns the engine oil to the oil fan after lubrication and cooling operation at the respective driving components. The cylinder head(400) has a check valve(500). A check valve(500) is installed at the lower portion of the oil supply passage of the cylinder head, and open to travel the engine oil toward the cylinder head. The check valve(500) cuts off the engine oil from cylinder head direction to cylinder block direction to remain a certain amount of the engine oil in the cylinder head.
