FILTER ASSEMBLY FOR FUEL INJECTORS
First Claim
1. A filter assembly for filtering hydraulic fluid in a hydraulically actuated fuel injector, the filter assembly comprising:
- a plurality of first rollers parallelly disposed one after the other, and defining first axes disposed in a first plane; and
a plurality of second rollers parallelly disposed one after the other, and defining second axes disposed in a second plane parallel to the first plane, each second roller of the plurality of second rollers being disposed between a consecutively arranged pair of first rollers of the plurality of first rollers to define one or more filtration zones for filtering the hydraulic fluid.

Abstract
A filter assembly for filtering hydraulic fluid in a hydraulically actuated fuel injector is disclosed. The filter assembly includes a plurality of first rollers and a plurality of second rollers. The first rollers are parallelly disposed one after the other, and define first axes disposed in a first plane. The second rollers are parallelly disposed one after the other, and define second axes disposed in a second plane. The first plane is parallel to the second plane. Further, each second roller is disposed between a consecutively arranged pair of first rollers to define one or more filtration zones for filtering the hydraulic fluid.
