Abstract
Improvements to the respirator valves and underwater breathing masks, essentially constituted and characterized by slides generally mounted in the air inlet of the respirator and which normally and permanently ensure the sealing of said orifice, except under conditions (emersion) and a privileged position (the one of the swimmer in normal position of swimming in surface) in which other devices ensure the opening of the valve.
