Abstract
The invention relates to a valve (24) comprising: a body (40) defining a cavity and provided with a first opening (60) that makes it possible to feed water into the cavity, a second opening that makes it possible to discharge water from the cavity, and a third opening that makes it possible to connect the cavity (41) with a chamber; a stopper (49) that is rotatable inside the cavity, the stopper comprising a depression (77) on the outer surface (90) thereof that contributes to the definition of a passage enabling the flow of water between the first and third openings in first angular positions of the stopper and moreover enabling the flow of water between the second and third openings in second angular positions of the stopper, a sealing device that makes it possible to ensure a sealed stopping of the first opening (60) by means of the stopper in said second angular positions of the stopper; and a second sealing device that makes it possible to ensure a sealed stopping of the second opening by means of a stopper in said first angular positions of the stopper.
