Une soupape (6) est installée au niveau de l'orifice d'expulsion. La partie supérieure de la soupape est un cône (61), et une pointe conique est orientée en direction de la vis sans fin. Le cône et la vis sans fin sont coaxiaux, et une surface conique du cône s'adapte dans l'orifice d'expulsion circulaire et forme un contact étanche avec celui-ci. Une lame en spirale (42) de la vis sans fin s'étend en spirale le long de la surface conique jusqu'à la partie inférieure du réservoir. La partie inférieure de la soupape est pourvue d'un dispositif d'extension et de rétraction (7) servant à entraîner la soupape d'expulsion à se déplacer vers le haut et vers le bas. Le cône s'adapte dans l'orifice d'expulsion circulaire, et assure l'étanchéité de l'orifice d'expulsion et un ajustement serré vis-à-vis de celui-ci par l'intermédiaire du dispositif d'extension et de rétraction, et la lame en spirale de la vis sans fin s'étend en spirale le long de la surface conique du cône jusqu'à la partie inférieure du réservoir.
