Abstract:

A purge valve for full face masks or helmets includes a base member fixed in the mask wall and having passages opening in a flat, annular valve seat surface. A manually operable valve member includes an outer cylindrical wall, an inner cylindrical wall reentrant from an end wall and is axially slidable on a stem extending from the base member against the action of a compression spring nested between the cylindrical walls. This invention relates to underwater diving equipment and more particularly to an improved purge valve for use in removing accumulated water from a divers mask or helmet.
