Fuel delivery rail assembly

Abstract

A fuel delivery rail assembly for supplying fuel to a plurality of fuel injectors in an engine is provided. The assembly comprises 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. High-frequency noise suppressing means such as a binding member is fixed within the conduit for connecting said one wall and the socket mounting wall. The binding member is comprised of a pipe, a bar or a rigid block. The binding member may be comprised of a body portion of an extending socket terminating with said 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.
