Abstract

A fluid reservoir assembly having a pan defining a drain opening and a plug disposed therein is disclosed. The pan includes a pair of ramps disposed on an inner surface thereof adjacent the drain opening. The plug includes a pair of wings in engagement with the ramps. The ramps increase in height relative to the inner surface of the pan along a first direction of rotation about the central axis. The plug is drawn into sealing engagement with an outer surface of the pan by rotating the plug in the first direction of rotation about the central axis thereby moving the wings up the ramps. The pan includes at least one stop to prevent over-rotation of the plug. The ramps define a recess to secure the wings in a closed position.
