摘要: A pressure sensitive valve (20) for a positive airway system (10) which allows bi-directional flow with low resistance. When from the air generator (12) of is lost, spring (28) actuated disc (32) moves away its compressed position to block outlet (12). By blocking (12), path entry contaminants significantly restricted in so doing, an alternate, resistance atmosphere exposed allow escape.
