Abstract:
A filter assembly for a fuel injector is provided. The filter assembly includes a first ring. The first ring includes a plurality of first apertures provided along a circumference thereof. The filter assembly also includes a second ring disposed concentrically with respect to the first ring. The second ring includes a plurality of second apertures provided along a circumference thereof. Each of the plurality of second apertures is disposed misaligned with respect to each of the plurality of first apertures respectively. The filter assembly further includes an actuation mechanism operably coupled to the second ring. The actuation mechanism is adapted to selectively rotate the second ring about an axis with respect to the first ring to, at least partially, align each of the plurality of first apertures with respect to each of the plurality of second apertures respectively to provide an unfiltered flow of a fluid through the filter assembly.
