ABSTRACT:
A vehicle skid control system including a wheel speed transducer, skid control circuitry responsive to the transducer for generating a control current output and a skid control valve responsive to the control current for providing single-gain control in a skid control mode. The skid control valve includes a first stage for generating a control pressure which is controlled exclusively by the current output of the valve driver, which control pressure is representative of the threshold pressure which an input metered pressure should not exceed if a skid condition is to be avoided. The control valve further includes a second stage pressure balancing system responsive to the pressure for allowing the metered supply pressure to be applied to a brake port as long as the metered pressure does not exceed the first stage control pressure. When the metered pressure exceeds the control pressure the second stage becomes operative to modulate the brake port pressure in accordance with the control pressure completely independently of variations in the metered pressure as long as the metered pressure remains above the control pressure from the first stage, thereby providing the single gain characteristic in the skid control mode.
