REINFORCED END CAP ASSEMBLY FOR PRESSURE VESSEL

摘要

A fuel rail or pressure vessel assembly extends along a longitudinal axis and includes a fluid conduit having an opening at either or both of the longitudinal ends of the conduit. The conduit has an inlet coupled to a high-pressure fuel source, a plurality of outlets, and a conduit interior that forms a fluid flow passageway between inlet and outlets. An end cap assembly is mounted to cover and close each fluid conduit opening. The end cap assembly includes a cup having a free edge that defines an aperture that leads to a cup interior. The cup has an inner surface facing the conduit interior. The end cap assembly also includes a reinforcement that is mounted to the inner surface of the cup. Both the cup and the reinforcement can be stamped metal components and are brazed together.
