Abstract
Un respirateur à ventilation forcée comprend un élément facial (20a) destiné à recouvrir au moins le nez ou la bouche d'un porteur, une pompe (10) destinée à fournir de l'air dans un volume délimité par l'élément facial (20a), un filtre (13) qui filtre l'air entrant dans ledit élément facial (20a) et un dispositif à soupapes qui commande le flux de l'air provenant de la pompe (10) et allant vers l'élément facial (20a) pendant une inhalation, et provenant de cet élément pendant une expiration. La pompe (10) comporte un ventilateur (12) entraîné par moteur électrique (11). Le dispositif à soupapes comprend une soupape d'entrée d'air (19), et une soupape de sortie d'air (22) maintenue fermée pendant une inhalation au travers de la soupape d'entrée d'air (19), par la pression de l'air provenant de la pompe (10), puis ouverte par l'air expiré. Ce dernier intervient aussi pour fermer la soupape d'entrée d'air (19) et prévenir l'entrée d'air expiré dans la pompe (10). Le ventilateur (12) est centrifuge et entraîné à vitesse sensiblement constante. Une soupape (14), disposée sur l'entrée d'air de la pompe (10), est conçue pour se fermer quand une certaine pression d'air règne dans la pompe (10) en aval du ventilateur (12).
