Problems solved by technology
[0002] In today's automobile brake valves, hydraulic valves are mostly used for braking, which requires that the output pressure of the liquid needs to be stable and can be controlled. Immediately connect the oil inlet to the oil outlet, causing the high-pressure liquid to flow into the brake instantly, which will easily cause an impact on the brake and affect its service life, and the output pressure of the liquid is unstable, and the pressure of the oil outlet is difficult to control; in addition, the hydraulic brake valve is due to Its precision is relatively high, so the requirements for pressure oil are also high. During use, it is necessary to strictly control the pressure oil to not contain impurities, otherwise it will cause wear to the valve core and affect its normal use.

Embodiment Construction
[0022] The following description serves to disclose the present invention to enable those skilled in the art to carry out the present invention. The preferred embodiments described below are only examples, and those skilled in the art can devise other obvious variations.
[0023] Such as Figure 1-5 As shown, a high-tightness automotive hydraulic brake valve includes a valve body 1 with an oil inlet 101, an oil outlet 102, and an oil return port 103 on the side. The oil inlet 101 and the oil return port 103 are located at the The right side of the valve body 1, and the axes of the oil inlet 101 and the oil return port 103 are in the same vertical plane; the oil outlet 102 is located on the left side of the valve body 1; the inner edge of the valve body 1 In the vertical direction, there is a valve hole 104 connected with the oil inlet 101, the oil outlet 102, and the oil return port 103. The valve hole 104 is provided with a spool 2 for controlling the on-off of the oil port....
