Hayashi, Y

This patent describes an internal combustion engine having a structure subject to high heat flux, a cooling system comprising: a coolant jacket disposed about the structure and into which coolant is introduced in liquid form and discharged in gaseous form; a radiator in fluid communication with the coolant jacket and in which coolant vapor is condensed to its liquid state; means for returning the liquid coolant formed in the radiator to the coolant jacket in a manner which maintains the level of liquid coolant in the coolant jacket at a first predetermined level. The first predetermined level being selected to maintain the structure immersed in a predetermined depth of liquid coolant. The coolant jacket, radiator and the liquid coolant returning means defining a cooling circuit; a reservoir in constant fluid communication with the cooling circuit; and a valve which controls the communication between the interior of the reservoir and the ambient atmosphere, the valve being operable to selectively control the pressure in the reservoir and the cooling circuit.
