Abstract
An electromagnetic actuator including a soft-ferromagnetic yoke is described. The electromagnetic actuator includes an at least substantially cylindrical circumferential wall covered at a first end with a base and at a second end with a top, the circumferential wall defining an axis in a direction from the base end to the top. An intermediate yoke section holds a permanent magnet fixed that leaves an inner space housing an axially movable core element being flexibly restrained with at least one resilient element. One of a base yoke section and/or a top yoke section houses an electromagnetic coil.
