Abstract

Cartouche compacte à double clapet de retenue de type champignon. La cartouche est compacte, conçue pour être utilisée dans diverses applications. La compacité de la cartouche est obtenue en intégrant le support du champignon d'un premier clapet au siège du deuxième clapet, en emboîtant les tiges des champignons et en faisant en sorte que d'autres éléments s'emboîtent. La cartouche est également autonome, ce qui facilite sa manipulation et réduit le temps nécessaire à son insertion dans un corps de clapet ou son retrait d'un tel corps. L'invention comprend aussi un clapet de retenue dans lequel la cartouche est maintenue dans une ouverture d'arrivée à l'aide d'une cage en treillis ouvert. Le clapet de retenue et la cage sont tous deux conçus pour être insérables dans un corps de clapet dans un sens seulement, pour éviter qu'ils soient mal installés.
