ABSTRACT:
A position regulator is provided which is effective to control, via a control unit, a pressure medium circuit to operate at different working pressures. The regulator comprises two or more pressure transmitting elements which divide an internal space into a number of pressure chambers, the pressure transmitting elements being arranged for axial movement within the position regulator. The invention provides pressure transmitting elements defining the pressure chambers which comprise diaphragms or the like which are attached in mutually spaced relationship in the position regulator and which, when subjected to a force, permit axial displacement movements.
