  • the Federverstellmutter 18 is rotatably connected to the Federverstellhülse 19 via a positive connection, so that they can indeed move axially to each other, but not rotate against each other.
  • the electrohydraulic drive 14 comprises a special electric motor and a hydraulic unit, which is selectively driven via a transmission by the motor. According to the embodiment of the door operating device 1, this has by means of the electro-hydraulic drive 14 the possibility to perform the opening movement of the revolving door automatically, during the opening movement, the revolving door is set in motion and the compression spring 13 due to an axially moving to the compression spring 13 adjacent piston 20th In addition, it is stretched.
  • the opening movement of the revolving door is initiated via the pressurized pistons 20, 21, wherein the drive unit 10 comprises a cam-roller unit for converting the axial movement of the piston 20 and 21 into a rotational movement of a shaft 22.
  • the said components are arranged inside the housing 11, so that the door operating device 1 can be installed in a plurality of revolving doors within the door leaves due to the narrow formation with a width of for example 40 mm.
  • the pistons 20 and 21 are acted upon via respective adjacent pressure chambers with a hydraulic fluid, wherein the fluid pressure via the electro-hydraulic drive 14 is available is provided.
  • the fluid connections may be in the form of channels which are integrated in the housing 11.
  • Fig. 2 and Fig. 3 show the view of the unit of the spring adjustment 15 and the pressure compensation unit 32, which is shown in Fig. 2 cut in an assembled view and shown in Fig. 3 as an exploded view in the disassembled state.
  • the non-rotating, d. H. 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, 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, which are designed according to the present embodiment as lip seals and are arranged twice radially in the lateral surface of the piston 34.
