Abstract
In a fluid-pressure operated anti-skid braking system operation of a control valve is controlled by a force of which the magnitude is determined by utilization of the pressure in a memory chamber defined between a pair of relatively movable spaced pistons. The piston carries a head which forms part of the valve, and the other piston is exposed to an operator-controlled pressure from an inlet passage.
