Abstract
A sump pan for a device such as a transmission or engine lubricating system includes an upper chamber and a lower chamber which are separated by a partition. The partition has an opening therethrough in which a filter media is positioned for filtering dirty fluid in the upper chamber so that clean fluid collects in the lower chamber. A suction tube extends through the partition for pulling the clean fluid for recirculation through the device utilizing the fluid such as a transmission or an engine. A bypass valve is also disposed in the partition so that if the fluid becomes too viscous to pass through the filter media, or the filter media becomes clogged, the bypass valve will open so that the fluid can still circulate.
