Abstract
A device for setting railway switches includes a plurality of interlinked hydraulic switching devices (6) connected to a separate reversible hydraulic drive unit in a manner offset in the longitudinal direction of the rails, wherein the working volumes of the hydraulic cylinder piston aggregates (6) are connected to driving movement in same direction. The pistons (20) or plungers (11) include push-open valves (18) for travel limitation.
