ABSTRACT:
A position regulator is provided which is effective to control, via a control unit, a pressure medium circuit to operate a different working pressures. The regulator comprises two or more pistons dividing a common cylinder into a number of pressure chambers, the pistons being arranged for movement relative to one another. The invention provides stop means for each separate piston, each stop means being individually adjustable to produce different lengths of stroke for the respective pistons whereby the output piston rod from the cylinder is caused to adopt a number of axially determined limit positions depending upon the control pressure applied to respective pressure chambers.
