Abstract
A cooling air bypass prevents premature failure of an engine in the event that cooling air from an external blower is somehow obstructed or shut off. The cooling air bypass includes a normally-closed valve in a wall of a conduit. During proper operation of the blower, the conduit conducts cooling air from the blower to the engine. If the blower malfunctions, however, such that airflow from the blower is impeded or stops, the valve opens to provide an auxiliary airflow path through the valve in the wall of the conduit and into the engine.
