A check valve for reinforcing operational stability of a hydraulic control high pressure solenoid valve is provided to ensure smooth operation of the check valve at a low pressure of the solenoid valve by closing a return passage using oil provided from a master cylinder to a brake. A check valve for reinforcing operational stability of a hydraulic control high-pressure solenoid valve comprises a return check valve unit(9). The return check valve unit includes a return passage(10), a check ball(12) and a check ball plate(13) on which the check ball is mounted. The return passage is connected to a circumferential passage of a valve body(5) in an axial direction of the valve body. The check ball is inserted into a groove(11) formed at a side of the return passage adjacent to a filter(8). The check ball plate is supported by the filter. |
