Abstract
A fuel delivery rail assembly for supplying fuel to a plurality of fuel injectors in an engine is provided. The assembly includes an elongate conduit having a longitudinal fuel passage therein, a fuel inlet pipe, and a plurality of sockets. One wall of the conduit opposite to the socket mounting wall includes a flat or arcuate flexible absorbing surface. A high-frequency noise suppressing device such as a binding member is fixed within the conduit for connecting the one wall and the socket mounting wall. The binding member includes is comprised of a pipe, a bar or a rigid block. The binding member may be a body portion of an extending socket terminating with the one wall. Thus, fuel pressure pulsations and shock waves are reduced by bending of the absorbing surface, and emission of high-frequency noise is eliminated.
