A method for manufacturing a magnetic valve and a corresponding magnetic valve, in particular for the use for electrically continuously adjustable shock absorbers of a vehicle. A valve housing and a magnetic armature which is movably supported relative to a longitudinal axis of an electrically energizable coil and which is at least partially surrounded by a pole tube which is at least partially surrounded by a coil body of the coil that in turn is cast with a casting compound, provides a corrosion protection cap covering an axial end of the pole tube. The corrosion protection cap establishing a connection to the casting compound and protecting the axial end of the pole tube against corrosion influences from the atmosphere.

Proportional electromagnetic actuator comprising: a magnetic casing; an electromagnetic plunger movable relative to the casing and having a first axial half; a first radial gap and a second radial gap which are each formed radially between the plunger and the casing, and which are positioned axially at the first axial half of the plunger. These gaps (26; 28) are formed by concentric annular chamfers (32; 34). A three-way valve for turbojet oil, which is actuated by an electromagnetic actuator with double chamfered gaps.

A solenoid is provided that includes: a primary package that is made of a molding resin and covers a solenoid body in which a coil is wound around a bobbin; and a secondary package that is made of a molding resin and covers the primary package. A contact surface between the primary package and the secondary package is provided with an anchor shape for enhancing joint strength between the primary package and the secondary package. The solenoid includes a connector part for electrifying the coil in addition to the solenoid body, the primary package covers both the solenoid body and the connector part, and the secondary package covers only a part of the primary package covering the solenoid body.

An electromagnet and method for producing the electromagnet. The electromagnet is intended to maintain pretensioning force of fastening by a force acting on a yoke over intended operating time under changing operating temperatures. The yoke encloses an armature that is provided with a flange, which conducts magnetic flux from a housing to the armature, the housing being connected on the one hand to a flange of the yoke and on the other hand to a core flange in a material-bonding manner by welding. The electromagnet can be used for actuation of valves, couplings or other electromechanical adjusting elements.

An electromagnetic apparatus includes a non-magnetic body structure above a substrate. The electromagnetic apparatus further includes at least one isolation structure including a dielectric material on a portion of the body structure and a magnetic structure having two separate portions, one on each side of the isolation structure. A first magnetic structure portion is on a first sidewall of the isolation structure on an upper surface and on a first sidewall of the body structure and a second magnetic structure portion is on an opposite second sidewall of the isolation structure onto an upper surface and on to a second sidewall of the body structure. The electromagnetic apparatus further includes an electromagnet on a side opposite to the isolation structure. The electromagnet is coupled with the magnetic structure and is a source of the magnetic flux lines when energized.
