Abstract
An arrangement for remote-adjustable regulation of a working piston cylinder 13, via pilot pressure, within a regulating range R and intermittent performance of a working stroke S from the regulating position R and back. The arrangement comprises a two-way directional valve 16 for working pressure serving to move the working cylinder, the control cylinder 36 of the directional valve being acted on in one direction by a spring member 35 and in the opposite direction by the pilot pressure in a servo piston cylinder 24. This can in turn, within the regulating range R, be acted on by the working cylinder 12 in the first direction. An increase or decrease in the pilot pressure opens the directional valve 16 in either direction, so that the working cylinder 12 is moved a little until the new pilot pressure is balanced by the action of the elastic part 28 and the spring member 35 on the servo piston cylinder 24. <IMAGE>
