摘要：A damper in a lf-contained electrically operated fuel pump for vehicle engines incorporating a positive displacement pumping element. The damper has a hollow toroidal flexible element in contact with the liquid fuel discharged from the pump for absorbing pulsations. A retainer with a locating plate on one side of the damper centers it in the pump housing and has resilient circumferentially spaced, radial fingers extending over and around the periphery of the toroid to confine it against destructive expansion while permitting limited expansion and contraction needed to absorb fuel pressure pulsations in pump operation.
