Pressure sensitive flow control valve










Image Number 7 for United States Patent #5878743.

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