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.

Abstract: A solenoid valve includes a valve that regulates the entrance and exit of oil, and a solenoid that operates the valve. The valve includes a hollow holder extending in one direction, ports including a supply port, a control port, and a discharge port, a passage that is formed in the holder and extends in the longitudinal direction of the holder, wherein a chamber connecting the supply port and the discharge port is formed in the middle of the passage, a spool movably installed in the passage, a channel that is formed in the spool and has one end connected to the control port and the other end connected to the chamber, a control land that divides the chamber into a supply chamber and a discharge chamber, and a spring that is installed between the holder and the spool to elastically support the spool.
