Title
(EN) JETTABLE MATERIAL FIRING CHAMBER CHECK VALVE
(FR) CLAPET ANTIRETOUR DE CHAMBRE D'ÉJECTION DE MATÉRIAU PULVÉRISABLE
Abstract
(EN) A check valve for preventing reverse flow of jettable material within a jettable material firing chamber during a firing event includes a free-floating plug. The check valve further includes at least one holding post, wherein the free-floating plug is arranged between at least one wall of the firing chamber and the holding posts, the at least one wall and the holding posts restricting the movement of the free-floating plug within the chamber.
(FR) Un clapet antiretour permettant d'empêcher un flux inverse de matériau pulvérisable à l'intérieur d'une chambre d'éjection de matériau pulvérisable au cours d'un événement d'éjection comprend un bouchon flottant libre. Le clapet antiretour comprend en outre au moins un montant de support, le bouchon flottant libre étant agencé entre au moins une paroi de la chambre d'éjection et les montants de support, ladite paroi et les montants de support limitant le déplacement du bouchon flottant libre à l'intérieur de la chambre.
