FIELD: means adapted for individual protection of breathing organs and serving for supplying of compressed air from air cylinder, where it is stored under high pressure, into self-rescuer's veil.
SUBSTANCE: air supplying apparatus has charging connection pipe with back valve, starting device with spring-loaded stem and spring-loaded valve, said parts being positioned in casing. Spring-loaded valve is fixed in air channel equipped with reduced-pressure cavity defined by membrane. Stem cooperates with one side of said membrane. Pusher mounted within casing is contacting with other side of membrane and with spring-loaded valve, which separates high-pressure cavity from reduced- pressure cavity.
EFFECT: increased efficiency of apparatus providing for uniform increasing of volume of air supplied into self-rescuer's veil as air is consumed from compressed gas cylinder.
