Abstract

The device (H) has a rotational circuit (U) with a rotating-directional seated valve (SU) between a pressure source (P) and a reservoir (R). Magnets (M1, M2) actuate a set of directional seated valves (S1, S1', S2, S2') and the rotational circuit. The rotating-directional seated valve is provided in a pass-through position, when the set of valves is in locking position and vice-versa. The magnets divide the rotating-directional seated valve such that the rotating-directional seated valve is actuated either alternately by one of the two magnets or jointly by both magnets.
