Abstract:
A fluid cleaning system comprising:a) a filter disk assembly, defining and being rotatable about an axis of rotation of said filter disk assembly, for removing particulate matter from fluid flowing through said filter disk assembly in a direction substantially parallel to said axis of rotation of said filter disk; and b) means in fluid communication with said filter disk assembly for circulating a flow of fluid through said filter disk assembly in a direction substantially parallel to said axis of rotation, said means for circulating including a clean fluid reservoir and a dirty fluid reservoir divided from one another by a wall having a flat section extending generally perpendicular to the axis of rotation of the filter disk assembly and having an opening in said flat section for passage therethrough from said dirty to said clean reservoir of a fluid which may contain particulate matter; said filter disk assembly being mounted adjacent said wall in said clean fluid reservoir and aligned with said opening to intercept particulate matter from fluid flowing through said opening from said dirty fluid reservoir into said clean filter reservoir, said filter disk in said clean fluid reservoir thereby having reduced exposure to abrasion from the particulate matter.
