A solenoid valve (1) is provided comprising a housing, an inlet, an outlet, main valve means located between said inlet and said outlet, said main valve means comprising a main valve element, pilot valve means adjusting a pressure difference over said main valve element and having a pilot valve element, a coil, a yoke arrangement magnetically linked to said coil, and armature means for moving said pilot valve element. Such a solenoid valve should achieve a large opening stroke without unduly increasing the coil and yoke arrangement. To this end said armature means comprise a first part attractable by said yoke means to perform an opening stroke, and a second part carrying said pilot valve element, wherein said first part is movable relative to said second part in a first section of said opening stroke and is dragging said second part in a second section of said opening stroke following said first section. |
