Abstract: A fuel rail assembly for supplying pressurized fuel to at least one fuel injector of an engine includes a hollow fuel rail extending along a fuel rail axis. The fuel rail includes an inlet for introducing the pressurized fuel into the fuel rail and at least one outlet for dispensing the pressurized fuel from the fuel rail. The fuel rail assembly also includes a bracket for attaching the fuel rail assembly to the engine. The bracket includes a fuel rail portion defining a first passage extending therethrough in the same direction as the fuel rail axis for receiving the fuel rail therewithin. The bracket also includes a mounting portion adjacent to the fuel rail portion and defining a second passage extending therethrough in the same direction as the fuel rail axis. The mounting portion is configured to receive a fastener for securing the fuel rail assembly to the engine.

Abstract: A pulsation damper is disposed within a fluid volume defined by a fluid volume wall such that the pulsation damper is exposed to pressure pulsations within the fluid volume. The pulsation damper includes a pulsation damper first half having a first damper wall which is flexible in response to the pressure pulsations; a pulsation damper second half having a second damper wall which is flexible in response to the pressure pulsations; and a damping volume defined between the pulsation damper first half and the pulsation damper second half such that the damping volume is fluidly segregated from the fluid volume. One of the pulsation damper first half and the pulsation damper second half defines a spacing member which maintains separation between the fluid volume wall and one of the first damper wall and the second damper wall.
