Abstract

Method of manufacturing an internal combustion engine exhaust valve, of the type cooled by liquid circulation and comprising a head containing a chamber and a threaded stem in said head and containing cooling fluid supply and return ducts that are substantially parallel that they end in said chamber, characterized in that it comprises at least two tubular ducts separated from each other and, for example, substantially symmetrical with respect to the longitudinal axis of said stem.
