<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, 1 2) 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 se at (5, 6) respectively, and each comprising a respective movable shutter (18; 2 8) cooperating with one of the said seats (5; 6) in the associated inlet chambe r (8; 12). Each interception solenoid valve device (16, 17) comprises an electromagnetic control portion (35, 50; 36, 50) which includes a movable co re (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 said 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 said intermediate duct portion (10) within a single winding or control coil (50).</p> |
