  • Such rotating devices for mounting, for example, on a boom of a construction machine are known in the market.

  • the object of the invention is to improve the devices known from the prior art and to design them in such a way that a compact design with a low overall height and yet high pressure medium throughput is achieved.
  • the invention is based on the idea to use the stator at the same time for the rotary mounting of the rotor and the rotary feedthrough, wherein the stator and rotating device optionally as one-piece or one-piece (Composite) body are formed. Accordingly, it is proposed according to the invention that the at least one media channel has a first channel section guided through the stator and a second channel section which communicates therewith and continues via the rotary feedthrough. In the stator more space in the radial direction is available, so that the media channels can be conveniently passed axially and deflected radially to the rotary feedthrough out without special fits would be required. This also allows large channel cross-sections realize, and it can be passed through sufficient pressure medium even with reduced height, which also the leverage ratios and in particular the introduction of force are improved in the implement.
  • the channel sections are each formed by two mutually perpendicular, with respect to the axis of rotation of the rotary feedthrough axially parallel and radially extending channel holes.
  • a further improvement can be achieved in that the radial channel bores are shut off in the stator at the radially outer end and are open to an axial internal opening of the stator. In principle, however, it is also possible with increased manufacturing effort to introduce the radial bores as blind holes.
