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: Disclosed is a breather valve for controlling a pressure of a transfer channel of a valve assembly. The valve assembly controls charging and discharging of hydrogen in a hydrogen fuel cell-based vehicle. The breather valve includes a vent ring movably received in a distal portion of the transfer channel and having a ventilation hole communicating with a main portion of the transfer channel; and a vent valve received in the distal portion of the transfer channel and screw-coupled to the transfer channel to open or close the ventilation hole.

Abstract: A valve assembly for controlling charging and discharging of a fuel prevents a high pressure charging pressure from being applied to a solenoid valve during fuel charging. The valve assembly includes a transfer flow passage composed of: a charging/discharging flow passage; a charging flow passage branched from the charging/discharging flow passage and connected to a storage tank; and a discharging flow passage branched from the charging/discharging flow passage and connected to the storage tank. Further, the valve assembly includes a first check valve configured to prevent backflow of the fuel transferred along the charging flow passage; a solenoid valve configured to open or close the discharging flow passage to regulate flow of the fuel; a second check valve configured to prevent backflow of the fuel transferred along the discharging flow passage; and a metering valve configured to control a flow rate of the fuel transferred along the discharging flow passage.
