Abstract (en)
[origin: US4385594A] A two-circuit cooling system for an internal combustion engine including first and second fluid circuits. The first fluid circuit includes a radiator and a liquid cooled heat source while the second circuit includes a radiator and an air-to-liquid heat exchanger. A fluid pump is connected across the two circuits and facilitates independent movement of the coolant through the two separate circuits. The pump accomplishes this by using an impeller member having multiple vanes on two opposite surfaces which are of different configuration and which are divided by a wall which cooperates with the housing to form two separate fluid chambers.
