ABSTRACT:
A device for reducing the rate of flow from a reservoir as the reservoir empties requires only a single chamber having an input, for receiving fluid from a reservoir, and an output port. There is a provision for sensing fluid level in the chamber, and a separate provision for reducing the flow through the output port when fluid level in the chamber has fallen to a predetermined level. In a preferred embodiment of the invention, fluid level is sensed by a float, which, after falling to a predetermined level, actuates a plunger that reduces flow through an aperature at the bottom of the chamber.
