  • Patent number: 5582743
    Abstract: A liquid filter apparatus particularly useful in removing particulates from parts washing solvent. A filter assembly includes an exterior, fluid, impermeable container, preferably in the form of a flexible sidewall bag, and an interior filter element with permeable sidewalls and inlet and outlet ends, preferably in the form of a sleeve. In use, liquid entering the sleeve may pass unfiltered entirely through the sleeve and exit through a sidewall of the exterior container, or all or any part of such liquid may pass through the filter sleeve and into a portion of the apparatus outside the sleeve but inside the exterior container. From this portion, the liquid emerges in a filtered condition. Consequently, the filter continually operates in both filtration and bypass modes.
