Abstract: A spoiler apparatus for a vehicle has a spoiler blade that is pivotally mounted about a transverse vehicle axis. An electric motor moves the spoiler blade between operating positions. The spoiler blade has a first mounting location on each end and is pivotally mounted there on the spoiler housing by way of a hinge. The hinges are advantageously each formed by an arched hinge lever, the hinge lever being rotatably mounted on one end on the spoiler housing fixed to the vehicle and mounted on the other end on the spoiler blade for conjoint rotation. Viewed transversely to the direction of the vehicle, the electric motor is fixed on the spoiler housing between the first mounting locations and, by way of a toggle lever mechanism, is operatively connected thereto in a second mounting location of the spoiler blade.

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.
