Abstract

Dans ce limiteur (1), un piston (6) est chargé par un ressort (7) et séparé l'entrée (3) de la sortie (4). Une bague torique (17) en assure l'étanchéité. Le ressort (7) s'appuie sur une cuvette (8) dont la partie inférieure (31) est aérodynamique. La paroi interne (24) de l'enveloppe (2) du limiteur présente des canaux (26, 27) de passage et une butée (25) limitant la course de la cuvette (8). En cas de surpression, le milieu sous pression peut rapidement s'échapper du limiteur.In this limiter (1), a piston (6) is loaded by a spring (7) and separates the inlet (3) from the outlet (4). An O-ring (17) seals it. The spring (7) rests on a cup (8) whose lower part (31) is aerodynamic. The internal wall (24) of the casing (2) of the limiter has passage channels (26, 27) and a stop (25) limiting the stroke of the bowl (8). In the event of overpressure, the medium under pressure can quickly escape from the limiter.
