  • Electromagnetic multiple actuator
    Patent number: 6526928
    Abstract: The multiple actuator for an electromechanically actuated valve has a housing and a plurality of armature shafts extending through the housing. Each of the armature shafts carry an armature, and two electromagnets which both lie inside the housing. Two springs act on each armature, forcing it into a position of repose between the electromagnets. This configuration makes optimum use of the available basic area above a valve which is to be driven. The armature has a maximum surface area, and optimum dissipation of heat through thermal conduction is possible via the corresponding housing underside.
