ABSTRACT:
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. 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 with one or other of the two side outlets from the pump body. The shape 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.
