Abstract (en)
[origin: WO2021110853A1] The invention relates to a switch valve block for a hydraulically actuatable working machine, comprising multiple valve block inlets for connecting to a respective pressure outlet of one or more hydraulic fluid pump(s), multiple valve block outlets for discharging a pressurized hydraulic fluid, and at least one valve which is arranged between the valve block inlets and the valve block outlets and is designed to produce a fluidic connection selectively between a first valve block inlet and a first valve block outlet or between a first valve block inlet and a second valve block outlet. The invention is characterized in that the first valve block outlet additionally already has a permanent fluidic connection to a second valve block inlet.
