Definitions

  • the throttle valve according to the invention is also an electro-hydraulically pilot-controlled proportional throttle valve, which is characterized in that the Throttle piston is operated by means of a differential piston.
  • the differential piston is firmly connected to the throttle piston by a piston rod.
  • the larger effective piston area of the differential piston is effective in the closing direction of the throttle piston.
  • the differential piston is acted upon from both sides by the control pressures applied by the pilot valve and its position is returned to the pilot in a control loop.
  • the position of the throttle piston can advantageously be returned to the pilot valve by a spring supported between the throttle piston and the pilot valve.
