ABSTRACT:
In order to rapidly bring the temperature of the coolant in the coolant jacket of an evaporative type cooling system to a derived target value, both the rate of heat exchange between the condenser or radiator of the system and the surrounding ambient atmospheric air and the amount of coolant in the cooling circuit are varied in a manner to change the pressure and therefore the boiling point of the coolant. With the invention coolant is positively pumped to and from a reservoir which is maintained at atmospheric pressure, into and out of a cooling circuit which is hermetically sealed during engine operation via a valve and conduit arrangement which includes only two electromagnetic valves and associated conduits. A reversible pump is utilized to pump the coolant to and from the reservoir. The coolant is permitted to pass unrestrictedly through the pump when the pump is not operating due to a pressure differential between the cooling circuit and the reservoir.
