Patent ID: 8915481

Claim:
A magnetically actuable valve, comprising an interior space delimited by at least one wall made of a magnetizable material, said wall including an inner leg and an outer leg, said interior space including a valve seat formed of material that is magnetizable so as to be magnetic only when subjected to a magnetic field with an outflow opening formed therein defining a centerline that extends perpendicular to a plane defined by the outflow opening, and comprising a magnet arrangement surrounding, in annular fashion, the inner leg of the wall, said magnet arrangement generating a magnetic circuit with a magnetic flux extending within the magnetizable wall, and comprising a valve body arranged to move within said interior space while in direct contact with said valve seat, the magnetizable wall including at least one discontinuity site, the discontinuity site being located between the inner leg and the valve seat, whereas the inner leg terminates at an axial distance from the valve seat, wherein at said discontinuity site the magnetic field is deformed and is caused to exit from the wall into the interior space and towards the valve body, wherein the valve seat is magnetizable by the magnet arrangement and conducts the magnetic flux to the outer leg and together with the wall forms the magnetic circuit, the magnetic flux proceeding from the wall through the valve body and the valve seat and is effective to pull the valve body laterally away from the center line of the outflow opening toward the inner leg of the wall.
