Abstract: A noise damper for a compressed-air system, for a brake system of a utility vehicle, including: a housing having an inlet channel for a compressed-air stream and with a chamber for accommodating sound-damping material, in which the inlet channel and the chamber are separated, perpendicularly with respect to the compressed-air stream, by a separating plate which is closed in a central region and which, in an outer peripheral region of the compressed-air stream, has multiple openings for introducing the compressed air directly into the chamber. Also described are a related pneumatic brake system and method.

Abstract: A seal arrangement for an air spring system for sealing off a shock-absorbing damper is disclosed. The shock-absorbing damper is situated in a rolling tube and in another tube, where the air spring system has at least one integrated control valve for the admission of compressed air into a pressure chamber formed between the outer tube, the rolling tube, and an air spring bellows that connects the outer tube and rolling tube. The seal arrangement is arranged between an inner circumferential surface of the rolling tube and an outer circumferential surface of the shock-absorbing damper and/or between an inner circumferential surface of the outer tube and the outer circumferential surface of the shock-absorbing damper. A support ring which is of step-shaped form on an outer circumferential surface is arranged on a distal end of the rolling tube and/or on a distal end of the outer tube.

Abstract: An air spring arrangement is disclosed. The air spring arrangement has at least one integrated control valve for the admission of compressed air into a pressure chamber formed between an outer tube, a rolling tube, and an air spring bellows that connects the outer tube and rolling tube. The at least one integrated control valve can be actuated, with multiple switching positions, by an integrated mechanical actuator as a function of an air spring stroke for ride-height adjustment. The pressure chamber includes a compression spring between a tube upper part and a tube lower part of the outer tube. A lever which is mechanically connected to the at least one integrated control valve can be actuated by at least one actuation lug, which is arranged on an end surface of the tube lower part, in order to realize a stepped characteristic for an aeration and deaeration of the pressure chamber.
