Abstract
An expansion tank for the coolant of a fluid-cooled machine, in particular a machine-operated water-borne vehicle or a truck includes at least one inlet connection arranged in the lower region of the expansion tank, and an outlet connection for connection of the expansion tank to a cooling circuit of an internal combustion engine. A filler nozzle is arranged in the upper region of the expansion tank and has a lower edge spaced from an expansion tank cover to limit the fill level. At least one valve seals the filler nozzle for filling the expansion tank and protects the cooling system from over-pressure. Furthermore, an air volume in the expansion tank, which remains on maximum filling of the expansion tank with coolant, can be adjusted.
