Abstract

The invention relates to a rotary distribution valve for hydrogen-propelled, four-stroke heat engines. The inventive valve comprises a body (4) and one or more moving cylindrical elements (1) per cylinder, which have been suitably machined such as to be equipped with transfer conduits (3) which, when aligned, open or close the combustion chamber at the appropriate time, thereby rotating the crankshaft by means of the fuel.
