Modular fuel injector with a damper member and method of reducing noise

A fuel injector (100) includes a body (200), filter (230), and damper member (400). The body extends along a longitudinal axis between an inlet end and an outlet end and has a wall defining a flow passage extending therebetween. The filter (230) is disposed in the flow passage proximate the inlet end. The damper member (400) is secured to the flow passage between the inlet end and the filter. The damper member (400) has outer (404) and inner surfaces surrounding the longitudinal axis, the outer surface (404) being contiguous to the wall of the flow passage to define at least one circumferential band (L1,L2) about the longitudinal axis in the flow passage. The inner surface defines an aperture (408) that extends through the damper member (400) to permit fluid communication between the inlet end and the filter (230). A method of reducing sound in the valve group subassembly is also disclosed.
