  • Patent number: 5054742
    Abstract: The magnetic valve includes a magnetic coil, at least one valve seat, a valve shank surrounded by a valve plate member and movable upon energizing of the coil to move the surrounding valve plate member away from the valve seat to permit fluid flow therethrough, and a resetting spring for resiliently retaining the valve member in a position for blocking fluid flow through the valve seat when the coil is deenergized. The spring action acting upon the valve plate member moves the valve shank away from the coil upon denergization of the coil. The valve plate member is movable relative to the shank and includes an annular resilient metal plate that has radial inwardly extending teeth and a coating of elastic plastic sprayed on to the plate to leave at least part of the teeth uncoated.
