Abstract

The main body of distributor has sliding valve fitted into its internal diameter which is operated by pressure applied to brake pedal. This valve connects the braking motors either to inlet orifice, connected to pressurized fluid source, or to outlet orfice leading to low pressure tank. One of its ends has a piston controlled by pressure in first chamber (connected to working orifice) inside which it moves. A second piston assembled parallel to the first one moves inside another chamber connected alternatively to fluid source and low pressure tank by means of anti-skid values operated according to angular displacement of wheels.
