<p>The valve magnetic drive comprises stationary electromagnet and mobile armature (14), containing integrated permanent magnet (20) formed by magnetic paste, or magnetic foil, with armature movable in axial direction. Armature contains at least two parts (16,18), between which is fitted permanent magnet, relative to axial direction. Both parts are typically plate-shaped, with second part (12) located directly opposite to electromagnet, while first part (16) contains protrusion (22), extending in axial direction towards electromagnet.</p> |
