Sound damping device for oscillatory components of a motor vehicle hydraulic system

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.
