Abstract

Ensemble filtre respiratoire comprenant un boîtier (1) sous forme de deux coques (2, 3) possédant des rebords circulaires (4, 5) pouvant se verrouiller réciproquement et créer un joint autour duquel on peut faire tourner une coque par rapport à l'autre. Chaque coque possède un orifice de gaz (9, 10) afin de permettre au gaz de s'écouler (12) à travers le boîtier et les axes de la longueur de ces orifices sont inclinés par rapport aux plans des rebords circulaires des coques respectives, de sorte que la rotation des coques modifie l'angle entre les orifices de gaz. Cet ensemble comprend également des moyens servant à placer un élément filtrant (8) à l'intérieur du boîtier à travers le trajet de l'écoulement du gaz.
