Abstract
The invention relates to a flat tubular damper for damping fluid pressure pulsations in fluid lines, in particular fuel pressure pulsations in fuel supply lines of motor vehicles, having at least one elongated chamber whose cross section is small in comparison to its longitudinal span and at least a part of whose chamber wall, being operationally connected with the fluid, can be elastically deformed by the fluid pressure pulsations. The invention provides that the cross section of the chamber changes continuously or discretely along its longitudinal span.
