Abstract
This invention relates to a hydraulic device comprising at least one adjuble working, control or regulating member between a pressure source (3) and the flow path of an outlet (5,R), said member establishing an unrestricted connection to a passage in one position with the pressure medium which is present flowing out via said connection by expanding. In the case of high working pressures and/or great quantities of delivery, a loud noise develops in such hydraulic devices throughout the whole flow path of the outlet when the jet flows out. According to this invention, this is prevented by a jet disturbing means (6) being arranged after said member and having a jet disturbing element (31) which is adapted to be biased, which is directed to the jet and adjustable in dependence of the pressure to be reduced from a ready position into working positions in which it increasingly disrupts the jet, said jet disturbing element (31) automatically taking up its ready position as soon as the pressure to be reduced approximately corresponds to the pressure behind the jet disturbing means (6).
