Abstract
An arrangement for filtering a liquid wherein the liquid accumulates in a sump pan includes a filter media, such as a pleated filter media which has a height approximating the height of the sump pan. Consequently, the filter media tends to interfere with the flow of filtered liquid towards a suction tube which returns the filtered liquid for recirculation. In order to facilitate flow of filtered liquid to the suction tube, the pan includes at least one shallow channel extending transverse to the pleats of the filter media. This arrangement with respect to vehicle transmission oil pans and vehicle lubrication oil pans.
