Abstract

Improvements in anti-skid brake circuits for motor vehicles, of the type that comprise a source of pressure fluid, a reservoir, a brake assist servo motor, including an actuation chamber that receives an actuating piston connected to a steering cylinder and an operator operated control valve capable of controlling fluid communications between pressure sources connected to a supply line to a system of anti-slip valves, capable of modulating fluid pressure in a series of brake actuators. in response to electrical instructions that come from a control device that responds to the deceleration of at least one wheel of the vehicle, characterized in that at least one filling duct is provided in each circuit that connects the drive chamber to each supply duct corresponding, by means of a calibrated one-step valve that allows the fluid only from the action chamber to the supply line, and in each supply line a shut-off valve between the pressure chamber and the supply and fill lines, the shut-off valve being controlled by the control device, so as to isolate the pressure chamber of the associated series of brake actuators during the modulation of the fluid pressure in the mentioned brake actuators, by the anti-slip valve system.
