Abstract
(EN)
This liquid injection device (2) is provided with a nozzle (9) which performs evacuation and liquid injection. The nozzle (9) is provided with: a cylindrical outer circumferential-side nozzle part (15); a cylindrical inner circumferential-side nozzle part (16) which expands and contracts through the outer circumferential-side nozzle part (15); and a columnar shaft part (17) which expands and contracts through the inner circumferential-side nozzle part (16). The outer circumferential-side nozzle part (15) has an electrolyte passage (19) which is disposed between the outer circumferential-side nozzle part (15) and the inner circumferential-side nozzle part (16) and through which an electrolyte flows. The inner circumferential-side nozzle part (16) has a decompression passage (28) which is disposed between the inner circumferential-side nozzle part (16) and the shaft part (17) and through which a gas inside a film outer package (4) is evacuated. The shaft part (17) is provided with a valve (25) which closes a suction hole (29) of the inner circumferential-side nozzle part (16). During the evacuation, the suction hole (29) of the inner circumferential-side nozzle part (16) in the extension state opens at a position that protrudes from a liquid injection port (20) of the outer circumferential-side nozzle part (15) in an axial direction of the outer circumferential-side nozzle part (15).
(FR)
Ce dispositif d'injection de liquide (2) est pourvu d'une buse (9) qui effectue une évacuation et une injection de liquide. La buse (9) est pourvue : d'une partie buse côté circonférence externe (15) cylindrique ; d'une partie buse côté circonférence interne (16) cylindrique qui se dilate et se contracte à travers la partie buse côté circonférence externe (15) ; et une partie arbre (17) en colonne qui se dilate et se contracte à travers la partie buse côté circonférence interne (16). La partie buse côté circonférence externe (15) présente un passage d'électrolyte (19) qui est disposé entre la partie buse côté circonférence externe (15) et la partie buse côté circonférence interne (16) et à travers lequel s'écoule un électrolyte. La partie buse côté circonférence interne (16) a un passage de décompression (28) qui est disposé entre la partie buse côté circonférence interne (16) et la partie arbre (17) et à travers lequel est évacué un gaz à l'intérieur d'un emballage externe de film (4). La partie arbre (17) est pourvue d'un clapet (25) qui ferme un trou d'aspiration (29) de la partie buse côté circonférence interne (16). Pendant l'évacuation, le trou d'aspiration (29) de la partie buse côté circonférence interne (16) dans l'état d'extension s'ouvre à une position qui fait saillie à partir d'un orifice d'injection de liquide (20) de la partie buse côté circonférence externe (15) dans une direction axiale de la partie buse côté circonférence externe (15).
