Abstract (en)
[origin: EP2062848A1] The electro hydraulic lifting module (S) has a main consumer (H) and an auxiliary consumer (N1 to N3), which are impinged by a same pressure source (P) over directional valves (22,27,34a,34b,35,37,38). Multiple auxiliary consumers are connected in series to a supply piping (33). The priority valve (P2 to P4) formed as three by two way pressure regulator (10) is arranged in the supply piping stream to the directional valve for each auxiliary consumer, which is impinged by the control pressure tapped upstream and downstream to the directional valve.
