Abstract: A fluid damper includes a body defining a fluid chamber and a first opening. The body is formed by a first cover and a second cover joined along an axial direction. A damping device is suspended inside the fluid chamber to damp pressure pulsations. The damping device is constrained by a peripheral edge. The damping device divides the fluid chamber into first and second sub-chambers. The first cover has a first wall portion into which a second wall portion of the second cover is received. A hermetic seal is formed between the first and second wall portions. The second cover has a terminal edge lying within the first wall portion of the first cover, the terminal edge being segmented into a plurality of fingers that cooperate with a ledge surface of the first cover to pinch the peripheral edge of the damping device.

Abstract: A fuel injection system includes a fuel rail, and a damper that is disposed inside the fuel rail. The damper includes outwardly protruding first barbs formed integrally on one end of the damper and outwardly protruding second barbs formed integrally on an opposed end of the damper. The first barbs and the second barbs each engage the fuel rail inner surface, whereby the damper is located and retained within the fuel rail. The first barbs and the second barbs may be generally triangular in profile and each extend at an acute angle relative to the damper longitudinal axis. In addition, the first barbs and the second barbs are each oriented in the same direction relative to the longitudinal direction, whereby the damper is asymmetric when viewed in side view.
