Abstract

A hydraulically actuated member (24) for adjustably driving an element (26) which is displaceable against spring-biasing (28) is supplied with operating fluid by a pump 21 driven by an electromagnet (12). In order to maintain the adjusting force, the distance over which the element can be moved, and the adjusting time independent of the force of the electromagnet (12) the latter is energised by pulses. <IMAGE>
