Abstract

The invention comprises an hydraulic-operated regulating arrangement, adapted such that it can offer a remote control of a control device, in the form of a control valve 21, where it is to be possible to bring a part 21a, belonging to the control device, from a first position towards and onwards to at least one second position and vice versa, where said regulator displays a first piston/cylinder arrangement 31 and a second piston/cylinder arrangement 32 and two lines or conduits 33, 34, adapted to allow a hydraulic connection between said first piston/cylinder arrangement and said second piston/cylinder arrangement. Both the first piston/cylinder arrangement 31 and the second piston/cylinder arrangement 32 are selected to be double?acting. A first means 37 is arranged such that it can prevent the entry of air into the said piston/cylinder arrangements 31, 32 and that said two lines or conduits 33, 34 are part of a hydraulic auxiliary system "H" with two control circuits 301, 302, built up and interconnected as communicating vessels or chambers when the piston 32a in the second piston/cylinder arrangement 32 is displaced to a predetermined position.
