A prioritizing method and arrangement for a hydraulic system including two independent hydraulic fluid supply units (4, 5) adapted to jointly and severally supply hydraulic fluid to at least two hydraulic components (2, 3). A cross-communication between the at lest two hydraulic components (2, 3) is controlled, with a flow of hydraulic fluid from one of the two hydraulic fluid supply units (5) being diverted to one of the at least two hydraulic components (3) to a substantial exclusion of the other of the at least two hydraulic components (2) in dependence upon an operating condition of the other of the two hydraulic fluid supplying units (5). A biasing force (F) acts upon the prioritizing arrangement so as to define an operating stage at which the respective hydraulic fluid supplying units (4, 5) exclusively supply hydraulic fluid to the respective ones of the at least two hydraulic units (2, 3).

A prioritizing arrangement in a hydraulic system including first and second independent hydraulic fluid supplying means adapted to jointly or severally supply hydraulic fluid to at least two hydraulic units of the hydraulic system with one of the at least two hydraulic units having a priority over the remaining hydraulic units with respect to being supplied with hydraulic fluid to at least a partial exclusion of the remaining hydraulic units, the prioritizing arrangement including means arranged between the first and second hydraulic fluid supplying means and the at least two hydraulic units for controlling a flow of hydraulic fluid supplied from the first and second hydraulic fluid supplying means to said hydraulic units such that in a first operational stage of the hydraulic system fluid flow is permitted from one of the first and second hydraulic fluid supplying means to at least the one of the hydraulic units having a priority over the remaining hydraulic units while fluid flow from the other of the first and second hydraulic fluid supplying means is essentially blocked whereas in a second operational stage of the hydraulic system the flow of hydraulic fluid from the one of the first and second hydraulic fluid supplying means is diverted from the one of the at least two hydraulic units having a priority to at least one of the remaining hydraulic units and fluid flow is permitted from the other of the first and second hydraulic fluid supplying means to the one of the hydraulic units having a priority, said first and second operational stages of the hydraulic system being a function of an operating condition of the other of said first and second hydraulic fluid supplying means.
