Electromagnetic valve with electric current feed for electromagnetic coil

摘要

The valve has the electromagnetic coil fitted in a magnet yoke and surrounding a magnetic armature section with fixed and movable parts. The two front sides of the two armature parts are parallel and orthogonal to the centre axis direction. At least one work point of stroke force characteristic can be determined over the current strength in the coil.The spring (12) characteristic can be progressively adjusted similarly as the stroke force characteristic, but more steeply. Both characteristics attain the highest value at the smallest air gap. The magnetic armature part end carries a sealing element coacting with a seat of a pressure line connecting union.
