ABSTRACT:
A liquid dispenser having an outer tank and an inner tank or trap at the bottom thereof with an inlet from the outer tank features a proportioning device at the inner tank inlet which includes an inverted cup-like member with a floating check ball therein. The parts are arranged so that the check ball offers decreasing impedance to flow from the outer tank into the inner as the liquid level in the outer tank decreases, whereby to provide a substantially constant rate of flow into the inner tank regardless of the liquid level in the outer tank.
