A steam iron pump assembly including a two-position selector having one position corresponding to a sudden discharge of steam and having its other position corresponding to spraying cold water. According to the invention the pump assembly comprises a pump body surmounted by a deformable bellows, and having two side outlets together with a rotary selector passing through the deformable bellows. A bottom portion of the rotary selector is surrounded by a sealing sleeve which is radially deformable level with one or other of the two side outlets from the pump body. The outline of the bottom portion is suitable, depending on the angular position of the rotary selector for applying the sleeve against one of the outlet orifices while simultaneously allowing water to pass through the other outlet orifice.

Cette invention concerne une pompe de fer à repasser à vapeur à deux modes de fonctionnement, soit un premier mode de projection de vapeur et un second mode de projection d'eau froide. Selon l'invention, la pompe comprend un corps surmonté d'un soufflet déformable, deux orifices de sortie latérales et un sélecteur rotatif traversant le soufflet déformable. Une partie inférieure du sélecteur rotatif est logée dans un manchon d'étanchéité que l'on peut déformer radialement à la hauteur de l'un ou l'autre des deux orifices de sortie latéraux du corps de pompe. Le profil de la partie inférieure susmentionnée est adapté pour appliquer, selon la position angulaire du sélecteur rotatif, le manchon d'étanchéité contre l'un des orifices de sortie tout en laissant passer de l'eau par l'autre orifice de sortie.
