Abstract
A reusable filter for mounting on an engine is disclosed herein. The filter includes cylindrical reusable filter mounted in a housing. The reusable filter includes an outer screen, an inner screen, and a ported cylinder between the outer and inner screens. The ported cylinder has a plurality of acutely angled oil-directing openings extending toward the inner screen to cause a swirling fluid motion in a partially filtered compartment around the inner screen to assist in trapping sediment in a contaminant trap located between the inner and outer screens.
