  • a multi-pin locking member can be configured to simultaneously fit into pockets corresponding to more than one valve port.
  • a single locking member could block one, two or all of the adapters installed on one side of a manifold from decoupling from engagement with the associated valve port.

Abstract

L'invention concerne un collecteur pour recevoir au moins un fluide. Le collecteur est construit à partir d'une pluralité de modules qui peuvent être interconnectés et configurés de manière à créer un collecteur particularisé. Des dispositifs d'accouplement interconnectant une cavité d'écoulement de chaque module peuvent être sélectionnés pour déterminer les caractéristiques d'écoulement de fluide entre les cavités d'écoulement de module. Chaque module comporte un ou plusieurs orifices de soupape. Des soupapes ou d'autres appareils de réception d'écoulement sont fixés au collecteur par l'intermédiaire d'adaptateurs. Une première extrémité de chaque adaptateur est dimensionnée et configurée pour entrer en prise avec un orifice de soupape, et une deuxième extrémité entre en prise avec l'appareil fixé.
