Summary

Three internally cooled exhaust valves having the same external dimensions but different throat designs were investigated to determine a method of obtaining increased coolant-flow area without increasing stresses. The valves were statically loaded to simulate stresses in the throat region caused by valve closure. Tests showed that a constriction in the coolant-flow passage can be removed without increasing stresses. Such an increase in the coolant-flow area lowers the crown temperature.
