Abstract: A damping element is proposed for a conduit conducting a gaseous or liquid medium through which pressure pulsations are applied, which is constructed as a hollow body through which the medium can flow, and is attached to a fastening element in such a way that the damping element is pushed into an opening provided in the fastening element. The inner surface of the fastening element may be provided with elevations and/or depressions produces a connection with enhanced frictional grip between the damping element and the fastening element.

Abstract: An assembly for reduction of pulsations and vibrations in a hose including a hose having an interior surface and a throttle being sized for insertion in the hose adjacent to the interior surface. The throttle includes a fluid passageway. The throttle further includes a first end adjacent to the fluid passageway. The first end includes a regulation device for regulating the flow of fluid through the fluid passageway to reduce pulsations and vibrations in the hose.

Abstract: A device for damping the sound emission from oscillatory components of a fluid container of a hydraulic system, primarily in a motor vehicle. At least one vibration damping mass is coupled to the wall of a component subject to sound damping. The mass is adapted to the vibration to be damped by selection of material, shape, and/or position on the wall. For example, the mass is a rib fastened to the wall or a strip adhered to the wall. In an alternate embodiment, the container has an inner and an outer wall with a gap between them. The gap is either evacuated, filled with a sound absorbing material or ribs on the wall extend in the gap or inside the inner wall.
