Patent ID: 7353844

Claim:
A solenoid-operated safety valve device ( 1 ) for control of the supply of a flow of a fluid, such as a gas or a liquid, to utiliser apparatus, comprising a duct ( 3 , 10 , 10 â€², 4 ) with an inlet ( 3 ) and an outlet ( 4 ) intended to be connected to a fluid source and to the utiliser apparatus, respectively, 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 ); first and second interception solenoid valve devices ( 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 said seats ( 5 ; 6 ); each interception solenoid valve device ( 16 , 17 ) comprising an electromagnetic control portion ( 35 , 50 ; 36 , 50 ) which includes a respective movable core ( 35 , 36 ) the position of which is controlled by a control winding ( 50 ); the solenoid-operated safety valve device being characterised in that the electromagnetic control portions ( 35 , 50 ; 36 , 50 ) of said interception solenoid valve devices ( 16 , 17 ) are disposed parallel to an intermediate portion ( 10 ) of said duct ( 3 , 10 , 10 â€², 4 ) lying between said valve seats ( 5 , 6 ) with the respective cores ( 35 , 36 ) aligned and movable in opposite directional senses along a direction essentially parallel to the axis of said intermediate portion of the duct ( 10 ), within a single winding or control coil ( 50 ).
