ABSTRACT:
A small hollow device extends through the wall of an engine compartment or box. It can be secured to the box by a flange around its outside edge attached to the wall of the engine box. A stop or valve, in the shape of the hollow device, is fitted into the hollow portion of the device, and may be held by another flange inside the wall of the box, to seal it in normal operation. However, this stop is secured within the hollow portion of the device by a flexible coupling that holds the stop in place in normal operation, but allows it to move to an open position when the nozzle of a fire extinguisher is pushed against it. This permits a fire within the engine box to be extinguished quickly and safely without the necessity of opening the lids of the box, which would admit large quantities of air to feed the combustion and flames.
