Abstract:
A valve with an electrodynamic actuator includes a magnet device that generates a magnetic field and a drive element that is movable relative to the magnet device. The drive element is pivotally mounted and comprises a current-carrying air coil that is arranged in the magnetic field and is fixedly coupled to a coil carrier made of a non-magnetic material. Sealing surfaces for sealing valve seats are arranged on two opposite sides of the drive element, such that the sealing surfaces face in opposite directions. A housing is comprised of a plurality of plastic housing parts and a metallic encasement. The metallic encasement surrounds an upper area of the housing in which the electrodynamic actuator is arranged and at least partially surrounds a lower area of the housing in which fluid channels are arranged.
