Abstract

La présente invention concerne un bouton de vanne de chasse autonome doté de multiples montants de guidage supérieurs (21) répartis le long d'un cercle sur un élément poussoir de commande (2). Chaque montant de guidage supérieur (21) est installé avec la première surface de guidage (211) et la seconde surface de guidage (212). Le premier socle de guidage (1) est installé avec la première rainure de guidage (11) et un plan incliné de guidage (12). Un élément poussoir commandé (5) comporte des montants de guidage inférieurs (51) répartis le long du cercle. La partie supérieure de chaque montant de guidage inférieur (51) est installée avec la troisième surface de guidage (510). Le second socle de guidage (4) est installé avec la seconde rainure de guidage (45) et la surface de guidage supérieure (41) et la surface de guidage inférieure (42). Le premier ressort (3) possède une extrémité fixée sur un élément poussoir de commande (2) et une autre extrémité fixée sur le second socle de guidage (4). Le second ressort (6) se fixe sur la partie inférieure de l'élément poussoir commandé (5). Cet élément poussoir peut être automatiquement remis en place, de sorte que la vanne soit fermée pour effectuer la chasse de la ration. Le bouton a une structure compacte et prend peu de place. Il ne possède aucun élément morcelé et présente un faible pourcentage de défaillance. Le fonctionnement du bouton est fiable.
