Abstract
Изобретение относитс к устройствам дл защиты детей и сопровождающего в непригодной дл дыхани атмосфере. Целью изобретени вл етс улучшение комфортных условий в оболочке. Устройство содержит герметичную газонепроницаемую оболочку 1 источник подачи воздуха в виде последовательно установленных вентил тора 7 и регенеративного патрона 6. Регенеративный патрон соединен выходом с оболочкой 1, а всасывающа лини вентил тора 7 сообщена с оболочкой через обратный клапан 11. Лицева часть 12 подсоединена к всасывающей линии вентил тора за обратным клапаном 11. 2 ил.This invention relates to devices for the protection of children and their attendant in an unsuitable atmosphere for breathing. The aim of the invention is to improve the comfort conditions in the shell. The device contains a sealed gas-tight envelope 1 air supply source in the form of sequentially installed fan 7 and regenerative cartridge 6. The regenerative cartridge is connected to the outlet 1 of the shell, and the suction line of the fan 7 communicates with the shell through a check valve 11. The front part 12 is connected to the suction line the fan behind the check valve 11. 2 Il.
