PURPOSE:To offer an anti-skid controller, with which risk of the braking effect's going out when the brake liquid feedback system has got any trouble, by furnishing the system with a one-way seal, which admits leakage of liquid pressure only in the direction from the reserver liquid chamber to output liquid chamber, between these two chambers. CONSTITUTION:This anti-skid controller is composed of No.1 valve mechanism having a control piston 7, which puts in communication or shuts off the circulating brake liquid between the input port 9 in connection to the master cylinder and the output port 10 in connection to the wheel cylinder and No.2 valve mechanism, a solenoid operated valve, having a ball element 12, which puts in communication or shuts off the liquid chamber b with/from the one c. This liquid chamber c is in communication to a reserver liquid chamber d, which is formed with a reserver piston 15, through a passage 7b provided around the axis of the control piston 7. In this arrangement, the sealing member between the reserver liquid chamber d and input liquid chamber a is formed with a sealing having one-way function such as a piston cup 17. Thus the intended purpose is attained. |
