  • Publication number: 20140291563
    Abstract: An actuating device for a control body of a valve includes an armature guide configured to receive a magnetic armature and an armature plunger in such a manner that the magnetic armature and armature plunger can move in relation to a longitudinal direction. An outer thread is located on a longitudinal end of the armature guide that is remote from the armature plunger. The outer thread includes a first cross-sectional profile forming a thread tip that points towards an exterior. A holding nut having an inner thread is screwed onto the outer thread of the armature guide and lies at least indirectly on the synthetic material casing of the electrical coil. The inner thread includes a second cross-sectional profile that is complementary to the first cross-sectional profile, and a thread base configured in a clamping region in a gap free manner with respect to the first cross-sectional profile.

  • Patent number: 8757586
    Abstract: A solenoid arrangement comprises a pole tube which is axially subdivided into a pole core section, a transition section, and a tube section. A magnetic flux between the pole core section and the tube section is interrupted by the transition section. An armature is movably guided in the pole tube and has, at its end facing the pole core section, a flange which axially projects from an end face. According to the invention, the pole core section has a stepped depression into which the armature can plunge and which, starting from the transition section, is subdivided into an annular collar, a shoulder, and a notch which is set back axially and radially. An axial dimension of the collar exceeds an axial dimension of the flange.

  • Patent number: 8480055
    Abstract: The invention relates to a solenoid wherein a magnetic discontinuity is formed in the pole tube reducing the effective material thickness, such as by reducing the thickness, particularly the wall thickness of the magnetically active material, the front face of the armature facing the pole core and a bottom face in the interior of the pole tube at the pole core each have a contour allowing mutual axial overlapping. This enables advantageous influencing of the force-stroke characteristic curve of the solenoid with low production effort.
