Abstract
An electromagnetic actuator, especially for the closure member of a valve, contains a solenoid unit, which has a cylindrical cavity closed at one end and open at the other end. An axially introduced guide tube for a magnetically movable armature is arrestable in the cavity by means of a securing device engageable in a first recess under spring force. To simplify connection of the actuator with and separation of the actuator from the component to be adjusted, provision is made for the securing device to lie completely within the solenoid unit and to snap automatically into the first recess when the guide tube is moved into a desired position in the cavity of the solenoid unit.
