ABSTRACT:
A fuel injector includes a body, filter, and damper member. The body extends along a longitudinal axis between an inlet end and an outlet end with a flow passage extending therebetween. The filter is disposed in the flow passage proximate the inlet end. The damper member extends from a first terminus to a second terminus. The first terminus is proximal to the longitudinal axis, and the second terminus is distal to the longitudinal axis. The damper member extends from the first terminus about the longitudinal axis towards the second terminus in a generally circular path to define an aperture that permits fluid communication between inlet end and the filter. The damper member is secured to the flow passage between the inlet end and the filter. A damper member is also shown and described. A method of reducing sound in the valve group subassembly is also disclosed.
