Electromagnetic actuator with torsion spring connected to lever by tube and extending partly into tube

摘要

Electromagnetic actuator has movable armature (17) with lever (1), supporting armature or forming armature, connected to rotatable tube (2). Spring (16) acts on lever or armature to bring lever or armature to intermediate location without energizing current.Movement of armature causes valve (6) of a combustion engine to be driven. Spring is torsion spring (16) connected with tube or part of lever or actuator and spring runs partly into tube
