Electromagnetically actuated, hydraulic high-speed manipulating valve

A hydraulic high-speed manipulating valve with at least one pressure-relieved cone seat valve is described, the valve body (8) of which is arranged in the central bore of a guide bush (7). The valve is actuated electromagnetically by a pot magnet, the armature (22) of which is arranged on a pin (20) of the valve body (8). The armature (22) forms a parasitic air gap (30) with an annular pole shoe (27) of the pot magnet and forms the working air gap (31) with its end face opposite the end face of the magnet core (23). The valve body (8) and its guide bush (7) are essentially free of magnetic field and can therefore be dimensioned without regard to the magnetic properties of their material.
