Abstract
A magnetically actuatable valve device, including an inner chamber delimited by at least one wall of magnetizable material, which wall forms a valve seat, and a magnet arrangement which generates a magnetic circuit with magnetic flux running in the magnetizable wall, and at least one magnetizable valve body which is moveable in the inner chamber, wherein at least one intermediate element is arranged in the wall extending around the inner chamber and with reduced magnetic conductivity in comparison with the wall, wherein the intermediate element includes a recess where a projection of the wall extends, where two magnetizable guide elements are arranged in the inner chamber on opposite sides of the valve body; and offset to the recess, wherein the guide elements guide the valve body and together with the wall form the magnetic circuit, wherein magnetic flux runs through the wall, the valve body, and guide elements.
