Definitions

  • the Pressure relief valve is adjustable, preferably also when the clamping pressure is applied, which allows an easy adjustment of the clamping force of the clamping element.
  • a line 20 which branches off from the pressure medium line 9 and a switching piston 21 receives an operative connection from the pressure medium line 9 the suction valve 13, which is also spring-loaded and thus the suction connection of the pressure chamber 7 via the suction line 12 to the tank 14 depending on Blocking or releasing the pressure level in the pressure medium line 9 or in the pressure chamber 17.
  • a pressure relief valve 22 for clamping pressure limitation is switched on, which via a line 23, which also drains leakage oil from the changeover valve 18, to the tank 14.
