ABSTRACT:
An actuator for a wheel anti-lock system, which comprises a first conduit connected to a brake master cylinder and a second conduit connected to a brake wheel cylinder. To the second conduit, there is connected a reservoir for reserving a predetermined amount of working liquid. Between the first conduit and the second conduit, there is interposed a feed change-over valve for opening or closing the communication between them. Between the second conduit and the reservoir, there is interposed a release change-over valve for opening or closing the communication between them. In the first conduit, there is disposed a normally open cut valve for closing the first conduit when in a skid control. To the first conduit, there is connected a pressure transducer in parallel with the cut valve. The pressure transducer includes: a body having a smaller bore connected to the brake master cylinder and a larger bore connected to the brake wheel cylinder; a stepped piston fitted in the two bores; and a spring for biasing the stepped piston toward the smaller portion thereof. When in the skid control, the pressure transducer feeds the second conduit with a pressure liquid, a predetermined amount larger than the pressure liquid which is fed from the 2 master cylinder, to the pressure transducer.
