The invention relates to an armature for an electromagnetic actuator, having a guide pin that is connected to an armature plate, characterized in that the armature plate ( ) is formed by a frame element ( ) that comprises soft-magnetic iron and is connected to the guide pin ( ), and at least one plate element ( ) that comprises a soft-magnetic material and is held in the frame element ( ).

Armature for an electromagnetic actuator with a sintered armature plate

An electromagnetic actuator for operating a cylinder valve in an internal combustion engine includes first and second housings secured to one another. Each housing has a cavity and a through bore extending therefrom. First and second electromagnets are disposed in the cavity of the respective housings. Each electromagnet has a yoke, a coil and a pole face. The pole faces are oriented toward and spaced from one another, and a reciprocating armature is disposed between the pole faces. A spring which urges the armature away from the first electromagnet has an end oriented away from the armature. A support cap is axially insertable in the through bore of the first electromagnet and includes a cap base having an inner face supporting the spring end. A locking arrangement secures the support cap to the housing and has a component axially insertable in the through bore with the support cap.
