Definitions

  • the proportional directional control valve 33 is switched in such a way that oil can flow from the actuating volume 19 of the pilot piston arrangement 18 through the lines 47 and 50 into the line 43 and through this into the drain device.
  • the result of this is that the spring 20 can push the piston 17 and with it the closure piece 16 of the control orifice 14 upwards, as a result of which the flow cross-section of the control orifice 14 is enlarged.
  • the orifice 41 limits the flow rate of the oil, but since more orifice can now flow out through the orifice 14, the oil pressure in the drive volume 5 drops and the spring 6 presses the main piston 4 down and the control valve 2 is moved in the closing direction.
