Abstract

Selon la présente invention, tandis qu'un élément d'actionnement d'ouverture/fermeture (63) adopte une attitude de fermeture, un état dans lequel un couvercle d'ouverture/fermeture (62) est disposé dans une position fermée dans une cartouche (6) est maintenu, et une soupape d'évacuation d'air (64) est disposée dans une position de fermeture de passage d'écoulement afin de fermer un passage d'admission d'air (61231). Dans cet état, lorsqu'une force d'aspiration d'une source d'aspiration (2) est appliquée, un espace d'aspiration (S1) à l'extérieur d'une chemise (5) à l'intérieur de la cartouche (6) est soumis à une pression négative. Pendant ce temps, lorsque l'attitude de l'élément d'actionnement d'ouverture/fermeture (63) passe de l'attitude de fermeture à une attitude permettant l'ouverture, la soupape d'évacuation d'air (64) se déplace, selon le changement d'attitude, vers une position d'ouverture de passage d'écoulement afin d'ouvrir le passage d'admission d'air (61231) à partir de la position de fermeture de passage d'écoulement.
