Oil pressure supply valve for a traction control system

摘要

An oil pressure supply valve for a traction control system, the structure of which is simple and small in size, that improves the function of the traction control system by securing enough flowing volume of the brake oil. The oil pressure supply valve includes: a body; internal passages connecting a master cylinder connection passage and a pump inlet connection passage that are formed perpendicular to each other in the body; a valve operating member including a valve seat for opening and closing the internal passages; a valve element having a ball valve which contacts or separates from the valve seat; a fixing screw member which is integrally formed with the valve element; and a spring supporting the valve operating member. Also, in the fixing screw member is formed an air passage through which air passes when the valve operating member moves up and down. Rings for preventing oil leakage are provided between the valve operating member and the body, and between the valve operating member and the valve element, respectively.
