ABSTRACT:
A gas-filled damping element for damping pressure pulsations, especially in an internal chamber of a pumping unit for pumping liquid fuel from a fuel storage receptacle to an internal combustion engine includes a rigid support member of a substantially plate-shaped or cup-shaped configuration, and a diaphragm having a marginal portion which is sealingly secured to a border zone or rim of the support member. The surface area of the diaphragm is greater than the projected area of the support member. The enclosed space between the rigid support member and the diaphragm is filled with a gaseous medium. A support element or portion extends into the enclosed space between the diaphragm and the support member, this support element having an abutment surface of an area smaller than the projected area of the support member and facing the diaphragm. The abutment surface serves for supporting the diaphragm when the damping element is exposed to extremely high pressures. The support member is provided with male connecting formations which engage with snap action in an annular groove of an extension of a stationary axle of the pumping unit to thereby hold the damping element in a predetermined position relative to the housing of the pumping unit.
