Abstract

Узел клапана выдоха для респиратора, причем указанный узел содержит верхний по потоку однолинейный откидной клапан (1) и нижний по потоку однолинейный откидной клапан (2), причем оба смонтированы в корпусе (3, 4, 5). Клапаны (1, 2) отстоят, образуя между собой объем (25), который действует как «мертвая зона», в которой остается часть только что выдохнутого воздуха, так что если верхний по потоку клапан будет протекать по какой-либо причине, то весь воздух, втягиваемый назад в респиратор из-за протечки, будет взят из этого только что выдохнутого воздуха и, таким образом, не будет загрязнен окружающим воздухом.
