Abstract

An automatic, positive anti-aeration system is assembled to function cooperatively with an engine cooling system radiator as an integral unit. An accumulator, vented to the atmosphere and containing a substantial amount of coolant liquid, is positioned adjacent to the radiator. Two separate fluid passages communicate respectively between the upper portion of one of the header tanks and the accumulator and between the lower portion of one of the header tanks and the accumulator. Valves control fluid flow in the two passages. When the pressure in the header tank rises above the preselected system operating pressure due to heating and expansion of the coolant liquid, the valve in the upper fluid passage opens, allowing coolant liquid and any gases trapped in the top of the header tank to flow into the accumulator. The gases are vented from the accumulator to the atmosphere and the coolant liquid is stored in the accumulator. When the coolant liquid cools and contracts, lowering the pressure in the cooling system to at least below the preselected system operating pressure, the valve in the lower coolant passageway opens, allowing coolant, but no air, to flow from the accumulator into the header tank. Using this system, the conventional radiator pressure cap and filler neck can be eliminated. The entire cooling system is filled and practically purged of air by pouring coolant into the accumulator.
