Abstract: The vehicle hydraulic system comprises a pump, an accumulator adapted to energize a closed-centre power brake booster, and a open-centre power steering mechanism, the supply line of the power steering mechanism including a throttle in parallel relationship with a control valve. The valve member of the said control valve is actuated by a stepped piston responsive to the fluid pressures in the accumulator and in the supply line downstream said throttle, both pressures acting against a spring, thereby insuring a minimum level of pressure in the accumulator.

Abstract: An anti-skid hydraulic braking system is disclosed which comprises a monitoring device responsive to the angular displacements of the wheels of the vehicle for controlling the fluid pressure level applied to a pressure modulator which in turn controls fluid communication between a standard automotive master-cylinder and the brake motors. The monitoring device is supplied with pressurized fluid from the pump of the general hydraulic system of the vehicle. Upon failure or malfunction of the pump, it is necessary to prevent the monitoring device from terminating fluid communication between the master cylinder and the brake motors which would prevent any further brake application. A control means is provided in the pressure modulator which comprises, in a chamber connected to the outlet of the pump, a reciprocable spring loaded piston which maintains the fluid communication between the master-cylinder and the brake motors when the pressure of said pump falls below a predetermined value.
