Abstract

Nel respiratore di protezione è prevista una valvola (12) di distribuzione dell'aria - comandata attraverso un dispositivo di comando (17) ed un attuatore (14) in funzione del segnale di un sensore di anidride carbonica (16) collegato all'entrata (2) per il gas di respirazione - per guidare l'aria di aspirazione dall'uscita (3) per il gas di respirazione, con contenuto in anidride carbonica dell'aria di aspirazione al di sopra di un valore limite preimpostabile, prevalentemente verso l'ambiente e, con contenuto in anidride carbonica al di sotto del valore limite, prevalentemente nel sacchetto di respirazione (7).(Figura)
