Abstract
A filter for filtering hydraulic fluid in a hydraulically actuated fuel injector. The filter includes a first disc structure and a second disc structure disposed axially spaced apart from the first disc structure. The second disc structure is also disposed parallel to the first disc structure. The filter further includes an intermediate structure extending from the first disc structure to the second disc structure. The intermediate structure includes a first surface and a second surface disposed opposite and parallel to the first surface. The intermediate structure defines a plurality of passages extending from the first surface to the second surface. Each of the plurality of passages is perpendicular to a longitudinal axis of the filter.
