Abstract
Presa d'aria subacquea avente generalmente una parte di ventilazione 3 comprendente un assemblaggio di una prima parte 3A e di una seconda parte 3B di tubo estendentisi in parallelo e comunicanti tra loro, un tubo principale 2 la cui estremità superiore é collegata alla prima parte 3A di tubo mentre la seconda parte 3B di tubo è provvista, alla sua estremità superiore, di un ingresso dell'aria 8 e, alla sua estremità inferiore, di una seconda valvola 11 di non ritorno e una luce di comunicazione 3D formata nella parete interna comune alla prima e alla seconda parte di tubo ad un livello intermedio tra l'ingresso dell'aria 8 e la valvola 11 di non ritorno. Tale disposizione è efficace per impedire che un flusso indesiderato d'acqua entri nel tubo principale 2 attraverso l'ingresso dell'aria 8 quando il subacqueo sta nuotando.
