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.
