ABSTRACT:
A damper for damping pressure pulsations in a liquid includes an outer tube having an inner surface defining an interior cavity, and an inner tube positioned within the interior cavity of the outer tube. The inner tube includes an outer surface such that at least one chamber is formed between the inner surface of the outer tube and the outer surface of the inner tube for containing a gas. The damper includes an exterior surface configured to be surrounded by the liquid and an interior surface configured to define a passageway through the damper for the liquid. The damper can define at least two, and in one embodiment, four separate chambers for containing a gas. The damper can be part of a fuel rail assembly and is positioned within a fuel rail configured to contain pressurized fuel.
