  • the non-rotating, ie fixed components of the spring adjustment 15 include the support sleeve 16, the threaded spindle 17, and an end arranged in the direction of the compression spring stop plate 29, which is arranged by means of a lock nut 30 on the threaded spindle 17.
  • the rotating components include the first gear 23, which is rotationally connected to the Federverstellhülse 19. This has a hexagon socket, which is axially joined to the hexagon on the Federverstellmutter 18.
  • the Federverstellmutter 18 includes an integrally formed spring plate 31, on which the compression spring 13 rests end side.
  • the support sleeve 16 is designed as a pressure compensation unit 32, which comprises a cylinder 33 in which a piston 34 is axially guided.
  • the pressure compensation unit 32 further comprises a closure element 36 which has a threaded bore into which the threaded spindle 17 can be screwed on the outside.
  • a compression spring 37 is arranged between the piston 34 and the closure element 36, which moves the piston 34 in the unpressurized state of the fluidic system in a direction in which the pressure compensation chamber 35 is increased in volume.
  • the piston 34 comprises sealing elements 38, wherein these are designed according to the present embodiment as lip seals and are arranged twice radially in the lateral surface of the piston 34.
