Abstract
A fluid communication device such as a fuel rail having a bellows damper positioned either in the end of the fuel rail or orthogonal to the axis of the fuel rail for dampening pulsed pressure waves from the flowing of the fuel. The bellows is a hollow tubular member having an enclosed end with a plurality of circular hollow ribs forming the outer surface of the bellows. The damper may also be located in a pocket or may be free floating in the fuel rail. An additional spring member is added to the damper for changing the spring rate characteristic of the bellows.
