| 摘要 |
The invention is directed to an electromagnetic valve (2) comprising a main valve member (16) cooperating with a seat (12), a pilot valve member (20), a core (18) linked to the pilot valve member (20) and a counter-core (22) cooperating with the main valve member (16), said core (18) and counter-core (22) forming a first air- gap (30), and a solenoid (28) configured for producing a magnetic field in the first air-gap (30) for moving the core (18) towards the counter-core (22). The counter- core (22) forms with the bottom (144) of the armature (14) a second air-gap (32) where, in the presence of the magnetic field and after movement of the core (18) towards the counter-core (22), said counter-core (22) is magnetically attracted towards said bottom (144) so as to open the valve. |
