Electric switch-through valve has two magnetizable connection protruding into magnetic coil to form magnetic poles connected via short circuit plate externally enclosing magnet coil

摘要

The valve has high and low pressure connections (2,3), a valve body magnetic armature (4) operating between the connections and a magnetic coil (5). Both connections consist of a magnetizable material and protrude into the magnetic coil to form magnetic poles connected via a short circuit plate (8) externally enclosing the coil. A magnetic iron-free volume (9) between the poles contains the magnetic armature.
