Electromagnetic actuator for opening and closing a valve device, a valve device having such electromagnetic actuator, an adjustable vibration damper having such electromagnetic actuator, and an automobile having such a damper
SubjectProblem to be solved: to provide an electromechanical actuator and a valve device realizing a controlled opening and closing operation for a wide range of volumetric flow through a valve device.SolutionIn particular, an electromagnetic actuator for opening and closing a valve device;Coyle unit that can be energized.In the Coyle unit,A Coyle unit capable of energizing the armature attached movably along the longitudinal axis of the electromagnetic actuator between the contracting position and the extended position, andHaving a first end and a second endWorking with an armatureA plunger movably supported along a longitudinal axis;The first end serves as a closure element with the plungerPlunger for opening and closing valve deviceAndPlungerThe first end isAt a first pressure, the pressure medium is projected into a first chamberThe second end isAn electromagnetic actuator disposed to protrude into a second chamber in which the pressure medium is held at a second pressure.Diagram
