Abstract

La présente invention concerne un dispositif de distribution (10) comprenant un boîtier de pompe (14), qui est équipé d'un adaptateur (12) pour un réservoir contenant un fluide. Ce dispositif comprend un boîtier d'adaptateur (24) qui présente un canal de passage (20), des orifices d'entrée (28) pour le fluide, une soupape d'admission (30) située dans une chambre annulaire (51), ainsi qu'un clapet anti-retour (32) situé dans une chambre à clapet (34). Le boîtier d'adaptateur (24) est constitué d'une partie supérieure (44) et d'une partie inférieure (46) qui forment la chambre annulaire (51) traversée au centre par une tubulure (52). Un fond (50) de la chambre annulaire (51) contient des orifices d'entrée de fluide (28) pour la position au-dessus de la tête du dispositif de distribution (10) et présente un rebord d'étanchéité (60) qui fait saillie dans la direction radiale à l'extérieur des orifices d'entrée (28). La soupape d'admission (30) est un disque de soupape annulaire élastique (31) qui entoure de manière étanche la rainure à anneau (58) et qui repose avec son bord externe sur le rebord d'étanchéité (60), rendant ainsi étanches les orifices d'entrée (28), mais qui, lorsque l'adaptateur (12) est en position au-dessus de la tête pour ouvrir les orifices d'entrée (28), se soulève du rebord d'étanchéité (60). Le dispositif de distribution (10) selon cette invention permet un fonctionnement sûr dans la position droite normale et dans la position au-dessus de la tête et peut être fabriqué de manière économique avec une construction simple.
