Abstract

1,087,565. Oil filter. PALL CORPORATION AND BOEING CO. Jan. 4, 1965 [Jan. 9, 1964], No. 265/65. Heading B1D. A filter adapted to accommodate sudden surges of flow in a hydraulic system without affecting the flow comprises a flow responsive device which allows fluid flow to a primary filter at all times but also allows fluid flow to a secondary filter element at a flow rate above a certain quantity. In the embodiment of Figs. 1 and 2 which incorporates inward flow cylindrical series filter elements 40 and 50 (Fig. 1), the flow responsive device comprises a flow restricting orifice 10 (Fig. 2), in the inlet passage 4, 7 and 8 to primary element 40, and a poppet valve 11 which allows by-pass flow to secondary filter element 50. Poppet valve 83 by-passes the secondary element 50. The pressure differential across the elements is indicated by magnetic pressure indicators 100 and 101 (Fig. 2). Element 40 may be corrugated epoxy resin impregnated cellulose paper. Element 50 may be made of sintered wire mesh with a surface of sintered-bonded fine metal powder. Elements 40 and 50 may also be made of paper, felt or porous sheets cf sintered powdered steel, bronze or aluminium. Drain port 90 may be opened by rotating nut 91.
