ABSTRACT:
An improved water cooled exhaust valve structure is disclosed for a rotary valve engine. The exhaust gases from an engine combustion chamber enter a side port in a rotary exhaust valve and flow axially through the valve to an exhaust outlet. Cooling water is sprayed axially into the exhaust valve and is directed in the gas flow direction from a location upstream of the side port. A novel deflector prevents the cooling water from entering the side port.
