Abstract
The second stage of the regulator comprises a first airflow circuit (117-10), controlled by a manostat diaphragm in a conventional manner which permits the assumption of the minimum required amount of air upon each act of breathing, with a minimum effort; and a second airflow circuit (4-14) combined with said first circuit, which permits to supply - in case of increased demand of air - a supplementary amount of air to meet any additional need of the user.
