Component for feeding a pressurized liquid to a washing tub of a washing machine, in particular for a dishwasher; said component comprising a hollow body having: at least one inlet (14, 14a, 14b) intended to be connected to a source of pressurized liquid, for example the water supply network; at least one outlet intended to deliver said liquid to a washing chamber defined by said washing tub; and a path for the liquid, which is defined in said hollow body between said at least one inlet (14, 14a, 14b) and said at least one outlet and includes anti-return means (26, 26a) for said pressurized liquid; a passage adapted to establish a fluid communication between said washing chamber and the environment outside of said washing tub, through said hollow body, thus bringing them to a pressure balance; said component comprises, furthermore, a valve device comprising a plug element which is mounted so as to be movable relative to said hollow body and is arranged to at least partially free and obstruct said passage; said component being characterized in that said valve device comprises an electric actuating system adapted to control said plug element; said hollow body comprising a pair of shaped half-shells (12a, 12b), which are coupled to one another in a fluid-tight manner; said path being defined by a sequence of hollow spaces, which are obtained between pairs of ribs, obtained in said hollow body and form, in its inside, a continuous channeling; said anti-return means (26, 26a) comprising at least one air break section; and said passage having an orifice and a hole made on said half-shells (12a, 12b) and adapted to put said hollow body in fluid communication with said washing chamber and with the environment outside of said washing tub respectively; said plug element being adapted to at least partially free and obstruct said orifice or said hole. at least one inlet (14, 14a, 14b) intended to be connected to a source of pressurized liquid, for example the water supply network; at least one outlet intended to deliver said liquid to a washing chamber defined by said washing tub; and a path for the liquid, which is defined in said hollow body between said at least one inlet (14, 14a, 14b) and said at least one outlet and includes anti-return means (26, 26a) for said pressurized liquid; a passage adapted to establish a fluid communication between said washing chamber and the environment outside of said washing tub, through said hollow body, thus bringing them to a pressure balance; said component comprises, furthermore, a valve device comprising a plug element which is mounted so as to be movable relative to said hollow body and is arranged to at least partially free and obstruct said passage; said component being characterized in that said valve device comprises an electric actuating system adapted to control said plug element; said hollow body comprising a pair of shaped half-shells (12a, 12b), which are coupled to one another in a fluid-tight manner; said path being defined by a sequence of hollow spaces, which are obtained between pairs of ribs, obtained in said hollow body and form, in its inside, a continuous channeling; said anti-return means (26, 26a) comprising at least one air break section; and said passage having an orifice and a hole made on said half-shells (12a, 12b) and adapted to put said hollow body in fluid communication with said washing chamber and with the environment outside of said washing tub respectively; said plug element being adapted to at least partially free and obstruct said orifice or said hole.
