Definitions

  • Inlet line 23 for hydraulic medium under pressure opens.
  • An overlap occurs in the control slide 13 in that the distance A between the control edges of the slide piston is smaller than the distance B between the control edges of the control channels 20, 21.
  • the lever 35 is adjusted accordingly along the scale 36.
  • the slide piston 16 is moved in the corresponding direction in the housing 15.
  • the adjusting piston 5 would move into the desired position and move the control rod 7 in such a way that the linkage 38, 42 brings the spool 16 into a closing position in which the control surfaces 17, 18 close the control channels 20, 21.
  • this position cannot be reached.
