Abstract

The present invention relates to a switching valve block for a hydraulically actuable work machine that comprises a plurality of valve block inputs for a respective connection to a pressure output of one or more hydraulic fluid pumps, a plurality of valve block outputs for outputting a pressurized hydraulic fluid, and at least one valve that is arranged between valve block inputs and valve block outputs and is adapted to selectively produce a fluid connection between a first valve block input and a first valve block output or between a first valve block input and a second valve block output. The invention is characterized in that the first valve block output furthermore already has a fixed fluid connection to a second valve block input.
