Beschreibung
Zusammenfassung:	A hydraulic arrangement is disclosed for distributing a fluid in pressure coming from a source of fluid in pressure among hydraulic units of a work vehicle. The hydraulic arrangement includes a priority valve configured to divide the flow of the fluid source between a subset of the hydraulic units on the base of an equivalent load sensing signal derived from the hydraulic units. The hydraulic arrangement further includes by-pass means fluidly interposed between the source and the subset of the hydraulic units and configured to allow direct passage of fluid by-passing priority valve from the source to the subset of the hydraulic units according to a predefined condition.
