Abstract

L'invention concerne un instrument de plongée, notamment un tuba qui comprend un tuyau partant d'un embout (2') sous forme d'un flexible d'amenée d'air (14a, 14b) en deux parties ou de la forme classique d'un tuyau relié à un flexible d'amenée d'air d'une seule pièce. En mode d'utilisation, les flexibles individuels ou le flexible tuba partant de l'embout est/sont en contact avec la tête de l'utilisateur. Une ouverture d'admission d'air se positionne derrière la tête. Selon l'invention, un clapet anti-retour (15a, 15b) est placé dans les flexibles d'amenée d'air (14a, 14b) ou dans un tuyau principal d'amenée d'air. Ce clapet anti-retour (15a, 15b) empêche un reflux de l'air expiré dans les flexibles individuels. De plus, un clapet de sûreté (17a, 17b) permet d'établir une liaison d'écoulement vers l'environnement extérieur lorsque une pression d'air prédéterminée de l'air expiré est atteinte. Cela permet d'éviter que de l'air expiré, déjà consommé, ne revienne encore une fois.
