Abstract
A fluid pressure device for operating the brake members of a vehicle with a wheel anti-locking function includes a fluid pressure actuator controlled by a control circuit including sensors arranged to detect the tendency of the wheels to lock, in order to interrupt the braking action. The pressurized fluid from, for example, the lubrication circuit of the engine and passing through a three-way solenoid valve piloted by the control circuit may act in the sense corresponding to activation or de-activation of the actuator, against the action of a resilient biassing member.
