<p>A control valve assembly for an hydraulic braking system comprising a positively actuated piston working in a longitudinal bore in a cylinder body. A first valve controls communication between a first inlet passage in the body and a first chamber defined by the bore, and a second valve controls communication between second inlet passage in the body, and a second chamber defined by the bore and spaced axially from the first chamber. Operation of the first valve is controlled directly by the piston, and operation of the second valve is controlled indirectly by the piston through at least one longitudinally extending push-rod.</p> |
