Abstract

Electrovanne de commutation (20) notamment soupape de commande de débit d'un système de rampe commune comportant un élément de soupape (22) mobile dans un boîtier (50). L'électrovanne est caractérisée par une installation d'amortissement (18) pour freiner l'élément de soupape (22) avant qu'il n'atteigne sa position de fin de course ; l'installation d'amortissement (18) a un premier segment (26) solidaire du boîtier et un second segment (28) couplé à l'élément de soupape (22). L'un des segments (26, 28) comporte une cavité (29) dans laquelle plonge l'autre segment (26, 28) avant que l'élément de soupape (22) n'arrive dans sa position de fin de course en formant un intervalle (36, 38) essentiellement radial.
