A hydraulic pressure damper element is manufactured by shaping a stainless steel tube; flattened each end of the tube; and sealing a gas within the tube. Wire retaining devices may also be attached to the ends of the damper in order to support the device within a fuel rail tube in a fuel system.

Low cost hydraulic damper element and method for producing the same

A fuel manifold having a rigid base portion with a fuel injector pocket defined therein, a top wall portion, a first substantially flat thin-walled portion extending between the rigid base portion and the top wall portion and a second substantially flat thin-walled portion extending between the rigid base portion and the top wall portion. The base portion, the top wall portion and the first and second thin-walled portions are defined by a one-piece aluminum extrusion and together define a fuel cavity that extends into the base portion and communicates with the fuel injector pocket.

Self-damping manifold

A fuel rail assembly comprising a fuel rail and a damper assembly in the fuel rail. The damper assembly includes a damper having an end and an inner surface defining a cavity, and a sealing member at least partially received in the end and bonded to the inner surface to substantially seal the cavity. The sealing member is preferably a metal wire that includes a sealing portion bonded to the inner surface to substantially seal the cavity. The bond is preferably formed by induction brazing, and the sealing member is coated with copper to facilitate the brazing. The invention also provides a fuel rail assembly comprising a fuel rail having a longitudinal axis and an inner wall. A damper assembly in the fuel rail includes a damper, and a spring locator coupled with the damper, the spring locator having two positioning portions outwardly biased to engage the inner wall of the fuel rail and position the damper assembly axially in the fuel rail. The spring locator is preferably a metal wire. Most preferably, the sealing member and the spring locator are the same device that both seals the damper and locates the damper assembly inside the fuel rail.
