<p>The solenoid valve device ( 1 ) comprises a duct ( 3, 10, 10', 4 ) with an inlet ( 3 ) and an outlet ( 4 ) and in which are formed first and second valve seats ( 5, 6 ) in series with one another, each between a respective inlet chamber ( 8, 12 ) and an associated outlet duct ( 9, 13 ), and a first and second interception solenoid valve device ( 16, 17 ) associated with the first and second valve seat ( 5, 6 ) respectively, and each comprising a respective movable shutter ( 18; 28 ) cooperating with one of the seats ( 5; 6 ) in the associated inlet chamber ( 8; 12 ). Each interception solenoid valve device ( 16, 17 ) comprises an electromagnetic control portion ( 35, 50; 36, 50 ) which includes a movable core ( 35, 36 ) the position of which is controlled by a control winding ( 50; 50 ). The electromagnetic control portions ( 35, 50; 36, 50 ) of the interception solenoid valve devices ( 16, 17 ) are disposed parallel to an intermediate portion ( 10 ) of the duct ( 3, 10, 10', 4 ) lying between the said valve seats ( 5, 6 ) with the respective cores ( 35, 36 ) aligned and movable in opposite directional senses in a direction essentially parallel to the axis of the intermediate duct portion ( 10 ) within a single winding or control coil ( 50 ).</p> |
