Abstract

Hydraulic brake systems are known which comprise antiskid control valves and a pressure fluid source where pressure fluid is fed via a valve device and an antiskid control valve to a wheel brake cylinder. The pressure fluid source includes two jointly driven pumps. The disadvantage of such a system is the constant presence of a high pump output although this high output is only rarely required. Therefore, according to the present invention, an energy saving is realized by having the suction connection of a first of two jointly driven pumps connected to a pressure fluid reservoir and the suction connection of a second of two jointly driven pumps connected to the pressure fluid outlet of an antiskid control valve.
