Abstract
In a device for operating rail switches, in which a plurality of mutually coupled hydraulic operating devices are arranged in an offset manner in the longitudinal direction of the rails, the cylinder-piston units of the hydraulic operating devices are connected to be driven in the same direction. The working volumes (13) of the hydraulic cylinder piston units (7) each comprise two regions (18, 19) with defined cylinder cross sections, wherein the respective regions (18) containing end-position securing means (20, 21), safety locking means and/or sensors, of the cylinder-piston units (7) arranged in an offset manner in the longitudinal direction of the rails have equal cross sections and the respective other regions (19) of the cylinder-piston units (7) arranged in an offset manner in the longitudinal direction of the rails have cross sections differing from one another.
