Abstract
Rotary joints are disclosed, such as for supplying fluid to a pressure chamber that is disposed between a rotatable component and a stationary component. The rotary joint may include a seal carrier having at least one channel for a fluid connection to the pressure chamber. At least two axially spaced apart sealing rings may be disposed on the seal carrier for a static sealing of the at least one channel. At least one sealing element may be non-rotatably disposed on the seal carrier and configured to form an axial and a radial seal of the pressure chamber. The at least one sealing element may be configured to bear on a ring element that is non-rotatably connected to the rotatable component when pressure is built up in the pressure chamber and the at least one sealing element may have means for reducing the axial pressure exerted on the ring element.
