  • Filament magnetic flux circuit
    Patent number: 5315278
    Abstract: A length of wire is toroidally wound, and then the toroid is encapsulated and cut in two along a plane that is perpendicular to the toroidal axis. The resulting portions are used as stator and/or armature of a solenoid, and in the solenoid the cut face of each forms one side of the solenoid's working gap so that the faces move toward and away from each other as the solenoid operates.
    Type: Grant

  • Solenoid pre-loader
    Patent number: 5244180
    Abstract: The solenoid portion of a solenoid-operated valve is resiliently biased by a pre-loader against an internal shoulder on the valve body to maintain precision of the stator-armature working gap during the useful life of the valve. Several embodiments of pre-loader are disclosed, including a Belleville spring, a wave spring, and an elastomeric ring.

  • Solenoid coil assembly
    Patent number: 5181004
    Abstract: A solenoid coil assembly comprises a bobbin containing an electromagnetic coil thereon, and a magnetically permeable conductor for conducting magnetic flux issued by said coil when energized. The magnetically permeable conductor is in the form of plural magnetically permeable U-shaped wires circumferentially arranged around the bobbin with one side of each wire disposed radially inwardly of the coil and the other side of each wire disposed radially outwardly of the coil. The sides of the wires pass through pre-formed holes in the bobbin.
