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.Breathing system comprising:- a body (1) comprising a base (2, 3, 4) and a first bore (5, 6) through this base (2, 3, 4), - a first piston (7) sliding coaxially in the first bore (5, 6), and comprising a second bore (8) separate from the first bore (5, 6) and coaxial, and a first abutment (9) against the body (3), - an elastic element (10),- a second piston (11, 12, 13) sliding coaxially in the second bore (8), this second piston (11, 12, 13) comprising:- a second limit stop (12) against the body (1), - a channel (13) comprising a first opening (14) forming a lumen which can be obstructed by the second bore (8), and a second opening (15) communicating with the first opening (14) and emerging outside the second bore (8), the elastic element (10) resting on the first piston (7) and the second piston (11, 12, 13). Figure 1.
