<p>The present invention features an arrangement wherein in order to prevent atmospheric air (or the like) from entering the cooling system of an engine wherein the coolant is boiled and the vapour used as a vehicle for removing heat from the engine, upon the engine being stopped or the temperature of the system falling below a predetermined level, the cooling system is filled with liquid coolant under the influence of the sub-atmospheric pressure which tends to develop under such conditions. Additionally, the coolant can be pumped in, in the event that some air has entered or remains in either of the coolant jacket or radiator associated therewith, to displace said non-condensible matter out of the system and thus completely obviate any tendancy for which would otherwise tend to produce a heat exchange reducing "embolism" to occur in the radiator conduiting.</p> |
