Patent ID: 7404541

Claim:
A solenoid valve comprising a base body having valve ducts extending through it and a magnet head having an electromagnet or solenoid means, which are arranged in sequence in the direction of a principal axis and between which a valve chamber communicating with a plurality of valve ducts is located, such chamber containing a magnet armature adapted to function as a valve member and able to be shifted in the direction of the principal axis, a stationary magnet core arrangement of the electromagnet means having a pole face arrangement facing the movable magnet armature, by which pole face arrangement the movable magnet armature is attracted for electrical activation of the electromagnet means and a damping plate arrangement arranged between the pole face arrangement and the movable magnet armature, such damping plate arrangement serving for reducing magnet armature impact, wherein the movable magnet armature is designed in the form of a plate-like element with base faces aligned with the direction of the principal axis, vis-à-vis to which element a plurality of pole faces, of different magnetic polarity, of the pole face arrangement are arranged, such faces being spaced apart in a direction athwart the principal axis, said damping plate arrangement consisting of a non-ferromagnetic material and extending at least partially over each of the differently polarized pole faces.
