Patent ID: 8381757

Claim:
A valve device for a hydraulic circuit dividing incoming volumetric fluid flow into at least two predetermined partial flows supplying first and second hydraulic consumers of the hydraulic circuit, comprising: at least one pressure compensator having a compensator housing with first and second fluid inlets; at least one variable passage opening triggerable by a proportional magnet for changing an opening area of said variable passage opening; a second passage opening with a constant opening area connected in parallel to said variable passage opening; a valve housing coupled to said proportional magnet and having said variable and second passage openings arranged in succession in a direction of travel of a control spool movably mounted in said valve housing and moved by said proportional magnet, said variable and second passage openings in said valve housing being connected in fluid communication to a pressure supply source, a third passage opening in said valve housing being connected in fluid communication to said first fluid inlet of said pressure compensator; a first partial flow of the volumetric fluid flow being supplied to said valve housing via said variable and second passage openings at a branch site of the hydraulic circuit; and a second partial flow of the volumetric fluid flow being supplied to said second fluid inlet of said pressure compensator at the branch site of the hydraulic circuit.
