Title
(EN) DEVICES AND METHODS FOR DELIVERING POWDERED AGENTS
(FR) DISPOSITIFS ET PROCÉDÉS PERMETTANT DE DISTRIBUER DES AGENTS EN POUDRE
Abstract
(EN)
A device for delivering an agent may comprise a source of agent; a mixing chamber for receiving fluid and the agent; an outlet in fluid communication with the mixing chamber to deliver the fluid and the agent; and an actuator configured to (1) deliver a first flow of the fluid substantially free from the agent through the outlet; (2) after delivering the first flow, deliver a second flow of the fluid and the agent through the outlet; and (3) after delivering the second flow, deliver a third flow of the fluid substantially free from the agent through the outlet.
(FR)
Dispositif de distribution d'un agent pouvant comprendre une source d'agent ; une chambre de mélange destinée à recevoir un fluide et l'agent ; une sortie en communication fluidique avec la chambre de mélange destinée à distribuer le fluide et l'agent ; et un actionneur conçu pour (1) distribuer un premier flux du fluide sensiblement exempt de l'agent à travers la sortie ; (2) après distribution du premier flux, distribuer un deuxième flux du fluide et de l'agent à travers la sortie ; et (3) après la distribution du deuxième flux, distribuer un troisième flux du fluide sensiblement exempt de l'agent à travers la sortie.
