Abstract (en)
[origin: US2005139729A1] 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.
