Abstract : A coolant subsystem for a torpedo propulsion system having an external combustion expansion engine. The coolant subsystem includes a valve which provides for one-way flow through the coolant subsystem. Inclusion of the valve prevents a backflow of exhaust gas into the coolant subsystem, thereby reducing the risk of torpedo failure due to engine overheating When the torpedo is launched in shallow water.
