Abstract

The invention relates to an electromagnetic actuator and a valve having such an actuator. The actuator has a first magnetic coil and a second magnetic coil, as well as at least one permanent magnet and an anchor that can be moved axially by the magnetic coils and the permanent magnet between a first and a second position, on which at least one spring device acts in the axial direction. The first and second magnetic coils as well as the first permanent magnet are disposed axially behind one another thereby, such that the first permanent magnet is disposed coaxially between the first and second magnetic coils.
