Abstract
An internal pulse damper for a fuel rail. The damper has an increased captive air volume and consequent improved damping and stress characteristics. The improved damper is a pillow having a modified flat oval cross-sectional profile, with two long diaphragm sides and rigid short sides connecting the two long sides. At least one of the short sides, and preferably both, is strengthened by being provided with a longitudinal reverse bend or inwardly-extending longitudinal rib generally parallel with the long sides. Preferably, the short sides are somewhat higher than the comparable short sides of similar prior art dampers, to increase the captive air volume, yet are not high enough to preclude installation of the improved damper within an existing fuel rail configuration.
