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.
Claims6
A position regulator comprising at least two pressure-transmitting elements (4, 5) which divide an internal space in said position regulator into a number of pressure chambers to which pressure medium is passed and from which pressure medium is conducted away in response to control means so as, via said pressure-transmitting elements (4, 5) to cause an output shaft (6) or the like displaceably mounted in said position regulator to adopt a number of axially determined positions in dependence upon individually adjustable stop means for respective pressure-transmitting elements, wherein said pressure-transmitting elements defining said pressure chambers comprise diaphragms (4, 5) or like means which are attached in mutually spaced relationship in said position regulator and which, when subjected to a force, permit axial displacement movements.
