Abstract

Clapet à piston comportant un corps (2), un siège de clapet (14), un obturateur (4) en forme de piston et un ressort de rappel (5). Le corps (3) comprend une enveloppe (3) munie d’au moins un orifice de sortie (10) du fluide sous pression, et un élément intérieur (6) qui est rapportée dans l’enveloppe (3). Le corps intérieur (6) porte le siège de clapet (14) et assure le guidage en translation de l’obturateur (4) dans le corps. En outre l’élément intérieur (6) comporte au moins une fenêtre (16) configurée pour guider le fluide du siège de clapet ver l’orifice de sortie (10). Figure pour l’abrégé : 2B
