Abstract

L'invention concerne un récipient d'évacuation garantissant une évacuation stable à l'aide d'une structure simple. Un récipient (1) d'évacuation comprend un récipient (3) destiné à recevoir un liquide (2), et un actionneur (4). Un cylindre (5) est fourni dans le récipient (3). Le cylindre (5) comprend une section (5a) de grand diamètre, une section inclinée (5c) et une section (5b) de petit diamètre. Un premier piston (7) comprenant un corps (8) de valve est placé dans la section (5a) de grand diamètre, et un second piston (9) est placé dans la section (5b) de petit diamètre, le second piston étant poussé par un ressort (10). Une partie saillante (8b) est formée sur la partie inférieure d'une section (8a) de valve du corps (8) de la valve, et un élément (11) de retenue d'espacement est placé entre le corps (8) de la valve et le second piston (9). Lorsque l'actionneur (4) est comprimé vers le bas, le second piston (9) est comprimé vers le bas par le liquide (2) dans le cylindre (5) jusqu'à ce que la partie saillante (8b) vienne en contact avec la section inclinée (5c). Lorsque la partie saillante (8b) vient en contact avec la section inclinée (5c) et est guidée vers l'intérieur, un espace est créé entre la section (8a) de valve du corps (8) de la valve et la paroi intérieure du cylindre (5), et le liquide (2) est évacué par une buse (4a) par la force de poussée du ressort (10).
