ABSTRACT:
An improved hydraulic control unit for brake systems incorporating antiskid control apparatus which eliminates impacts on the brake pedal during an antiskid regulation cycle, which is of simpler design than known prior art and which requires less accumulator energy includes a control piston disposed on and spaced from the inlet chamber side of an outlet piston and a piston shaft connected between the outlet piston and the control piston. The control piston defines one boundary of a reaction chamber and a spring disposed in a control chamber disposed on the side of the control piston remote from the outlet piston prestresses the control piston and the outlet in the direction of an outlet chamber disposed on the side of the outlet piston remote from the inlet chamber. A reaction piston defining on one end thereof the inlet chamber and on the other end thereof the other boundary of the reaction chamber is slidably disposed on the piston shaft.
