The gear-adjustment (1) has a first (2) and second (5) chamber for pressure medium, separated by a longitudinally movable piston (3). Two valve arrangements (30,42), controlled by an electric control (52), connect the pressure medium chambers with a pressure medium source (43,49) or with a sink . The first and second valve arrangements have pressure medium inputs (32;38), outputs (34;41) and outlets (33;39). A third valve arrangement is controlled by an electric control. The pressure of the pressure medium chambers is measured by a sensor (36). |
