Abstract
An inflatable aircraft evacuation slide system includes a primary valve, a bust disk and a valve leakage trap operatively disposed between the primary valve and the burst disk. The valve leakage trap comprises a small exhaust vent opening into a flow restriction orifice in the gas path between the primary valve and the burst disk. In operation, when the aircraft emergency exit is opened in the armed condition, the primary valve opens and pressurizes the chamber until the burst disk ruptures allowing inflation gases to pass through the flow restriction orifice to inflate the inflatable evacuation slide. Because there is a substantial pressure drop across the flow restriction orifice, the presence of the valve leakage safety vent in the orifice does not result in significant loss of inflation gas needed for inflating the inflatable evacuation slide. In the event of leakage past the primary valve, however, the valve leakage trap safely vents the leakage pressure to the atmosphere.
