Abstract

Means designed as a valve housing (1) for distributing the flow of hydraulic oil generated from a unit (P) to a first (5:1) and a second (5:2a-5:2d) consumer with different priorities, comprising inlet (2) to the first consumer (5:1) and the second consumer (5:2a-5:2d) control valves (6a-d) and an outlet (3) in connection with a hydraulic tank (T). It comprises a housing (1) containing a means of priority (7) arranged between the first consumer (5:1) and the second consumer (5:2a-5:2d) control valve (6a-d), a means (18) in the second consumer (5:2a-5:2d) control valve (6a-d) for delivering a signal flow to the means of priority (7) via a passage (11) arranged in the housing, regulator (8) for regulating the flow to the first consumer (5:1) and the second consumer (5:2a-5:2d) control valve (6a-d) on the basis of the signal flow and a means (14, 16) of attaining a drop in pressure of the signal flow when operating the second consumer (5:2a-5:2d) control valve (6a-d).
