Selon l'invention, la garniture d'évacuation comprend un élément de déviation (33) déplaçable pour le réglage de la quantité d'eau de chasse s'écoulant hors du réservoir de chasse (11) par unité de temps, lequel élément de déviation est espacé de la fenêtre d'écoulement (13) d'une distance radiale en formant un interstice annulaire (47). Au moyen du déplacement de l'élément de déviation (33), le trajet d'écoulement (I, III) vers la fenêtre d'écoulement (13) côté carter peut être allongé ou raccourci.
