Abstract
A device with a torque-proof first structural component and second structural component that is connected to the first structural component in a rotatable manner at least in certain areas. Hydraulic fluid can be supplied to lubrication points via the first and second structural components. An interface between the structural components has first and second transition areas arranged at a distance from each other in axial extension of the structural components. During operation, a pressure is applied to the first transition area which is higher than a pressure applied to the second transition area. A sealing appliance is arranged in the area of the interface between the first and second transition areas, which includes a threaded area in an area of a surface of one of the first and second structural components facing towards a surface of the other of the first and second structural components.
