Abstract: A reusable, ecological, long lasting, washable, non disposable filter for lubricant oils and fuels to be used in internal combustion engines or in any other equipment to help prolong the live of the lubricant oils and equipmen One or several essentially cylindrical independent filtering element place one inside the other, each filtering element consisting of a fine stainless steel cloth of a different mesh as needed for an optimal filtration, filtering out large, medium and small particles down to 5 microns if needed. The fin stainless steel cloth is enclosed in and retained by an open mesh and a number of rods that forms a cage extending longitudinally between two en caps being joint to form an assembly of a single unit by resin caps at each en thus forming an independent, leak proof filtering element that keeps the fine stainless steel cloth in position even during cleaning procedure that includes pressurized air that is forced through.

Abstract: The dislodgement of the soft washer of a fluids rate of flow saving or limiting device comprising a fluid pressure actuated needle type shutter and a flow restricting washer assembly through which said shutter passes to obstruct the free flow of the fluid depending on the pressure thereof and inlcuding a soft washer sandwiched between two hard washers is prevented by enclosing said soft washer within a housing having a circular bottom provided with an opening of a predetermined diameter larger than the diameter of said shutter, a cylindrical wall extending upwardly along the periphery of said bottom to a distance sufficient to constitute a cavity for receiving said soft washer, and a lid to cover the housing and having an opening of the same diameter as said bottom, said lid being arranged with respect to said cylindrical wall so as to sandwich said soft washer between said lid and said bottom, said soft washer having an opening of a diameter smaller than the diameter of the openings in said lid and said bott
