Abstract (en)
[origin: WO2011127874A2] The active member of the hydraulic locking device equipped with mechanic locking and retention for setting of the railway switches switch rails and crossing movable points consists of hollow piston and the controlling piston, in which the hollow piston (10) is connected to the hollow piston rods (6, 12), in which the compressive springs (13, 24) are situated seated to the flanges (31, 5) on the hollow piston rods (6, 12) and slide bushings (16, 25) on the piston rods (49, 50) of the controlling piston (32). The piston rods (49, 50) of the controlling piston (32) are connected with endings (19, 20) via hollow pins (23, 34) and via dog grooves (17, 22) in endings (19, 20) with retention sleeves (1, 18).
