  • the technical solution deals in hydraulic equipment for locking device locking device with hydraulic cylinders in parallel connection designed for railway turnouts switch rail setting.
  • the emergency manual throw-over of the locking device is commonly applied via external manual pump by means of swinging, or rotating movement with application of the three-way valve for the function change.
  • the disadvantage of the individual hydraulic drives and described synchronization of the running is the perplexity and demandingness of manufacture process. Another disadvantage is the spatial exigency of independent drives and deterioration of the system of tamping and maintenance.
  • the disadvantage of series arranged systems is the high demandingness for pressurization of the system and this way the increased jeopardy of pressure liquid leakage and possible failures in the system.

  • Currently known systems with parallel connection from the view of principle have not solved the synchronization of the single cylinders piston rods movement when the geometry volume differs one from another.
  • the manual emergency setting of the hydraulic system disadvantage by means of independent manual pump is the high spatial exigency, higher complexity and lower readiness because of necessity to switch over the functions.

  • the transfer valves 13 in pistons 12 of the hydraulic cylinders 11 are adjusted to the overflow pressure corresponding with necessary setting force of pistons 12, which enables the little bit higher pressure of the hydraulic liquid source to secure the proper activity of the self-acting regulation valves 10. This pressure is limited by the common safety transfer valves 13.
  • the opening of the transfer valves 13 is carried out for instance the case occurs, when the partition penetrates between the switch rail and the stock rail of the turnout and the hydraulic liquid pressure on the piston side 12 is increased in front of the transfer valve 13.
  • the transfer valves 13 also perform their function when the railway vehicle is trailing wrongly adjusted switch, when the working liquid pumping from the piston one side 12 to the opposite side is quickly carried out.
