ABSTRACT:
In known brake pressure control units having two pressure control valves arranged in parallel, a tipping lever arrangement is provided for the distribution of the preload force provided by a spring to the control valves which in the event of a failure of one brake circuit will increase the change-over point of the intack brake circuit. This tipping lever arrangement is complicated. Therefore, a brake pressure control unit having two pressure control valves arranged in parallel is disclosed in which the arrangement for the distribution of the preload force comprises a piston tiltable within limits which piston is subjected to the spring force and is directly operatively connected with ends of the two control pistons.
