Abstract

Système de respiration comprenant :- un corps (1) comprenant une base (2, 3, 4) et un premier alésage (5, 6) au travers de cette base (2, 3, 4), - un premier piston (7) coulissant coaxialement dans le premier alésage (5, 6), et comprenant un deuxième alésage (8) distinct du premier alésage (5, 6) et coaxial, et une première butée (9) contre le corps (3),- un élément élastique (10),- un deuxième piston (11, 12, 13) coulissant coaxialement dans le deuxième alésage (8), ce deuxième piston (11, 12, 13) comprenant :- une deuxième butée (12) de fin de course contre le corps (1),- un canal (13) comprenant une première ouverture (14) formant une lumière obstruable par le deuxième alésage (8), et une deuxième ouverture (15) communiquant avec la première ouverture (14) et débouchant en dehors du deuxième alésage (8),l’élément élastique (10) prenant appui sur le premier piston (7) et le deuxième piston (11, 12, 13). Figure 1.
