Abstract
Spring strut with a pneumatic spring and an oscillation damper which can be adjusted as a function of the support pressure. The pneumatic spring has a spring space bounded by a U-type bellows, which spring space is pneumatically connected to a damping device which can be adjusted as a function of a support pressure. A component which having a duct connects the spring space and the damping device is embodied without a hose and is integrated in the spring strut in such a way that it does not form any essential surface change in an unrolling piston associated with the U-type bellows and the unrolling piston forms at least a part of this duct.
