Abstract
An electromagnetic actuator is disclosed. The actuator has a coil arrangement which can be excited electrically, and has an armature. The armature is mounted such that it can move axially in the coil arrangement, is composed of soft magnetic material, and is moved in the axial direction when the coil arrangement is excited. A guide sleeve is fixed in the coil arrangement and guides the armature in the axial direction. The guide sleeve is produced from a soft magnetic material.
Claims15
An electromagnetic actuator configured to operate a valve arrangement, the actuator comprising
- a valve control element configured to be moved by a linear actuator in the axial direction between a first actuating position and a second actuating position;
- and
- a valve control lever coupled to the valve control element and to the valve arrangement, wherein the valve control lever is configured to move between a first valve position and a second valve position, wherein the valve control lever is coupled to the valve control element via a slide which is mounted such that the slide can be moved in the axial direction on the valve control element, wherein the slide is prestressed in the first actuating position such that the valve control lever is forced to the first valve position, and wherein the slide is configured to be moved to the second actuating position such that the valve control lever is forced to the second valve position.
