Diaphragm damper device coiled wave spring and damper system

A damper system comprising:

• a cover coupled to a housing, wherein the cover cooperates with the housing to define a fuel chamber;
• a coupling member attached to an inner side of the cover;
• a diaphragm damper device arranged in the fuel chamber;
• and
• a coiled wave spring arranged between the diaphragm damper device and the cover and configured to fix the diaphragm damper device to the housing with its elastic force,
• wherein the coiled wave spring includes a coil portion, a winding initiation portion, and a winding termination portion, wherein the winding initiation portion and the winding termination portion form flat seat windings, the seat windings each have a larger outer diameter than the coil portion, and one of the seat windings is configured to be fixed to the diaphragm damper device;
• wherein one of the seat windings is fixed to the diaphragm damper device;
• wherein another one of the seat windings is fixed to the coupling member;
• wherein the coupling member is located intermediate the coiled wave spring and the cover;
• and
• wherein a tab of the diaphragm damper device is swaged onto said one of the seat windings, and a tab of the coupling member is swaged onto said another one of the seat windings.
