ABSTRACT:
Electromagnetically actuated valve arrangement for flowing media comprising a sleeve in which an intake and a discharge valve each comprising a valve seat are applied. A permanent magnet arranged axially displaceable is provided between the valves, the flow of the medium from the intake to the discharge valve being controllable via this permanent magnet. In order for the valve arrangement to be simple and thus inexpensive in manufacture and to also reliably operate at high frequencies of the permanent magnet, it is proposed in accord with the invention that the permanent magnet comprises continuations in its outer region and at both sides, these continuations proceeding in the moving direction of the permanent magnet and extending beyond or over the valve seats.
