ABSTRACT:
An air cooled exhaust valve provided primarily for use with an internal combustion engine, or the like. The valve is of the type having an elongated stem and an enlarged head formed at one end of the stem. The stem is axially slidably mounted within a housing while the enlarged valve head cooperates with a valve seat in the housing. A fluid passageway in the housing is connected at one end to a source of pressurized air and at its other end is open to the valve stem adjacent the valve head so that pressurized air flows axially down along the valve stem and across the valve head to cool both the valve head and stem.
