Abstract (en)
[origin: EP1092863A2] The valve has an axially guided piston-shaped valve element movable against the force of a closing spring and that acts on a closure element and presses it against a valve seat. The valve element forms the armature of an electromagnet supplied with current to augment the closing force of the spring and has guide sections offset in the axial direction that guide it in the bore and has a reduced cross-section outside the guide section region.
