PURPOSE: An oil control valve is provided to improve NVH(Noise, Vibration, Harshness) by preventing abnormal noise caused by air remained in a valve device as the residual air is discharged before starting an engine. CONSTITUTION: An oil control valve comprises a valve body(10) and a relief valve(20). The pressure of oil supplied to the inside an engine is delivered when starting the engine so that the valve body reduces pressure exceeding a set level. The relief valve is formed on the valve body, thereby forming an air flow path. The air pushed back by the pressure of the oil delivered to the valve body is discharged to the outside through the air flow path. |
