Abstract

An anti-lock hydraulic brake system comprising a separating valve (14) and a regulating valve (19). A combined arrangement is provided wherein the valves are connected into each other. The movability (play s) of the piston (30) affords the event that a compensating volume for the control action in the event that the output of the pump is insufficient in specific situations requiring a large amount of fluid for control.
