An electrodynamic actuator, in particular for a microvalve or a micropump, includes a magnet arrangement for generating a magnetic field and a control element movable relative to the magnet arrangement. The control element includes an energizable air-core coil () which is arranged in the magnetic field and firmly coupled to a coil carrier () made from a nonmagnetic material.

Micro value comprising an electrodynamic actuator having stationary magnet arrangement and a moveable air-core coil

A valve device includes a valve having an electrodynamic actuator. The electrodynamic actuator includes a movably mounted control element having a coil and a magnet arrangement immovable relative to the coil. A driving force caused by energization of the coil and transmitted to the control element substantially is linearly dependent on the current intensity. A front-end electronic unit is connected with the coil and includes a capacitor connected in parallel to the coil. A method for controlling a valve as mentioned above provides that, upon actuation of the electrodynamic actuator, during energization of the coil by a voltage source, a capacitor connected in parallel to the coil is charged. After termination of the energization by the voltage source, the coil is energized further by a discharge of the capacitor.
