Control device for electromagnet with core without friction and application for valves with continuous control

摘要

The electromagnetic transducer drives an inner hub (4) laterally. The hub has a rear chamfer with shoulders on the armature channel holding it in place in the rest position. The armature (2) has electrical winding mounted coaxially around the hub centre. The hub is attached to a front and rear flexible section (14,15) covering the front and rear of the armature. The magnetic field moves the hub forward, displacing the flexible section.
