Abstract
A linear solenoid includes a pole tube; a housing jacket that encloses the pole tube; a coil that encompasses the pole tube; and a displaceable armature that is received in the pole tube. An overlap range between the housing jacket and an axially displaceable component that is in operative connection with the pole tube adjusts in order to adjust a magnetic force. The component is adapted to be actuated from outside in a mounted condition of the linear solenoid. The pole tube guides the component axially and the component has an external thread engaged with an internal thread of the housing jacket.
