ABSTRACT:
A coolant accumulator for use with the cooling system of an internal combustion engine, having a cooling radiator with a filler opening in it, provides positive anti-aeration of the engine cooling system and positive recovery of all coolant. This is accomplished by mounting a dual-compartment recovery tank above the filler opening of the radiator to permit free flow of fluid between the filler opening of the radiator and the bottom of a high pressure compartment of the tank. A pressure-actuated one-way valve is located in a passage interconnecting the top of the high pressure compartment with a second compartment. The valve is opened when the pressure in the radiator (and consequently, the high pressure tank) is a predetermined amount above ambient atmospheric pressure to permit fluid to flow from the high pressure compartment in the second compartment. The second compartment is vented to the atmosphere and has a filler opening in it to permit the addition of liquid coolant to it. The bottom of the second compartment either communicates directly through a gravity-operated check valve to permit flow into the top of the high pressure compartment or, alternatively, is connected through the gravity-operated check valve to the filler opening of the radiator. Thus, in the event of the loss of pressurization in the cooling system of the vehicle coolant flows by means of gravity out of both compartment into the vehicle cooling system. Lack of coolant in either of the compartments is a positive indication of a fluid leak somewhere in the engine cooling system and the accessories connected thereto.
