  • Publication number: 20190234256
    Abstract: Disclosed herein are an oil pump control valve and, specifically, an oil pump control valve allowing a discharge port and the inside of a solenoid part to communicate with each other through a spool so as to relieve pressure inside the solenoid part. A spool flow path, a vent hole, and a spool notch are formed so as to allow the solenoid part to communicate with the outside regardless of the flow of fluids when the valve is operated, thereby enabling the internal pressure of the solenoid part to be relieved. In addition, the spool and a rod are integrated such that the axial misalignment of the spool can be prevented and a holder has different diameter such that the flow of fluids can be controlled even during an abnormal power shutdown.
