Abstract
An electromagnetic actuator for operating a final control element has at least one solenoid which is arranged in a housing and acts upon an armature constructed of laminations oriented essentially toward control element. The control element may be a charge cycle valve. At least one lamination of the armature has at least one passage opening which forms a duct for transporting a medium.
Claims19
An electromagnetic actuator for operating a control element comprising:
- at least one solenoid which is arranged in a housing, and
- an armature constructed of laminations upon which the at least one solenoid acts,
- wherein at least one of said laminations of which the armature is constructed has at least one passage opening which forms a duct for transporting a medium.
A process of assembling an electromagnetic actuator for operating a control element and having at least one solenoid arranged in a housing comprising:
- constructing an armature upon which the at least one solenoid is to act of individual laminations, and
- automatically creating a duct for transporting a medium when the individual laminations are joined to construct the armature.
