Abstract
The invention relates to a valve system for supplying fluid from a pair of fluid pressure sources to a load. A feed valve is provided which feeds--when required--a partial flow of the second fluid pressure source into the feed line of the load which is connected to the first fluid pressure source through a directional control valve. The feed valve comprises a pressure-compensating valve to control the volume of the partial flow and a switching valve to automatically open the pressure-compensating valve when required.
