Abstract:
1. A reusable remote filter comprising: a cylindrical-shaped filter housing having an open end and a closed end; a tubular woven metal mesh filter element fitting concentrically within the filter housing; and a cap, the cap having an inlet opening and an outlet opening therein, the inlet opening and the outlet opening being substantially coaxial and perpendicular to an axis of the tubular pleated woven stainless steel filter element, the cap being threadedly assembleable to the filter housing, the outlet opening being in fluid communication with a first port at a right angle thereto, the first port smoothly increasing in diameter as it extends from the outlet opening to be substantially of the same diameter as the inner diameter of the tubular woven metal mesh filter element when the reusable remote filter is assembled, the inlet opening being in fluid communication with an immediately adjacent enlarged local region that provides a flow passage, the local region being in fluid communication with a distribution region extending from the local region around both sides of the first port to encircle substantially the entire periphery of the tubular woven metal mesh filter element and tapering from a maximum distribution region adjacent the enlarged local region to a minimum distribution region at a position substantially diametrically opposed to the enlarged local region; the cap having a mounting flange for mounting the reusable remote filter on a flat surface with the axis of the tubular woven metal filter element parallel to the flat surface; whereby fluid entering the inlet opening of the reusable remote filter is distributed above and around a diameter exceeding the diameter of the tubular woven metal mesh filter element while being gradually deflected toward the tubular woven metal mesh filter element without passing through a flow restriction between the inlet opening and the periphery of the tubular woven metal mesh filter element.
