Abstract
An emergency breathing system has an anti-suffocation valve located in a housing between a source of breathable fluid and a distribution mask. The housing has a chamber which is connected to the distribution mask and an opening which connects the chamber with the surrounding environment. The anti-suffocation valve responds to an inhalation demand of a recipient to allow air from the surrounding environment to enter the chamber and satisfy the inhalation demand of a recipient to allow air from the surrounding environment to enter the chamber and satisfy the inhalation demand. A hydrophobic filter surrounds the opening and prevents the entry of any water present in the surrounding environment into the chamber which could inhibit cyclic inhalation of breathable fluid by the recipient.
