Abstract
Die Erfindung betrifft einen hydraulischen Steuerblock mit wenigstens zwei Druckversorgungskreisen, die jeweils ein oder mehrere hydraulische Verbraucheranschlüsse aufweisen, und mit wenigstens zwei Hydraulikpumpenanschlüssen, wobei eine Ventilanordnung vorgesehen ist, mittels der jeder der wenigstens zwei Pumpenanschlüsse wahlweise einzeln oder in Kombination mit wenigstens einem der übrigen Pumpenanschlüsse wahlweise mit wenigstens einem oder mehreren der Druckversorgungskreise verbindbar ist bzw. sind und weiterhin wenigstens eine Direktanbindung eines Verbraucheranschlusses pro Pumpenanschluss vorgesehen ist. The invention relates to a hydraulic control block having at least two pressure supply circuits, each having one or more hydraulic load ports, and having at least two hydraulic pump ports, wherein a valve assembly is provided by means of each of the at least two pump ports, either individually or in combination with at least one of the remaining pump ports is selectively connectable with at least one or more of the pressure supply circuits and are still provided and at least one direct connection of a consumer connection per pump connection.
