ABSTRACT:
The present invention provides a non leak check valve typed traction control valve. A low pressure check valve8, which is provided in a pressure rise channel independent of a main oil passage of a TCV (Traction Control Valve), is opened during the normal braking when a driver operates a brake. Accordingly, oil pressure corresponding to the degree of braking is quickly provided. Further, when the TCS (ESP) is operated on the basis of signals from various sensors for the purpose of stably driving a vehicle even though the brake is not operated, the low pressure check valve provides an excellent airtight seal against the pressure rise channel. Therefore, pressure capable of controlling a wheel cylinder is sufficiently maintained at low pressure (10 bar or less).
