MODULAR FUEL INJECTOR HAVING DAMPER MEMBER AND NOISE REDUCING METHOD

摘要

PROBLEM TO BE SOLVED: To provide a fuel injector having a body, a filter and a noise damping member. SOLUTION: The body has a wall portion extending between an inlet end and an outlet end along a longitudinal axis for defining a flow path extending between both ends. The filter is located near the inlet end in the flow path. The noise damping member is fixed between the inlet end and the filter in the flow path. The damper member has outside and inside surfaces encircling the longitudinal axis, and the outside surface contacts the wall portion of the flow path to define at least one peripheral face zone around the longitudinal axis in the flow path and the inside surface passes through the damper member to define an opening allowing the communication of fluid between the inlet end and the filter.
