ABSTRACT:
A device for transferring a pressure medium has a first stationary component and a second component that is inserted into the first stationary component such that it is rotatably drivable therein. A first annular chamber is defined between the first stationary component and the second component and has a first and a second axial end. The first axial end is delimited at least partially by the first stationary component and the second axial end is delimited at least partially by the second component. An inlet line and an outlet line are connected to the first annular chamber. The outlet line guides the pressure medium to a consuming device. Radially extending sealing slots are defined between the first stationary component and the second component at the first and the second axial ends whereby the sealing slots have adjustable slot widths. The first and the second sealing slots are simultaneously adjustable into a same direction with respect to the slot width by an axial relative adjusting movement of the first stationary component and the second component.
