Der magnetische Kernstift wird durch eine magnetische Anziehung durch die Magnetzone des Schlüsselschaftes gegen die Rückstellkraft des Federelementes in Richtung seiner Freigabestellung beaufschlagt. Die Magnetkraft ist stärker als die Federkraft, so dass der Kernstift durch magnetische Anziehung gegen die Rückstellkraft des Federelementes in die Freigabestellung bringbar ist. Ferner kann vorgesehen sein, dass der magnetische Kernstift mit einem in Richtung seiner Sperrstellung von einem vorgespannten Federelement beaufschlagten zweiten Gehäusestift zusammenwirkt, der durch eine magnetische Abstoßung des magnetischen Kernstiftes durch die Magnetzone gegen die Rückstellkraft des Federelementes in eine Freigabestellung bringbar ist. Während bei der zuvor beschriebenen Variante die beiden Magnete, die die Magnetzone einerseits und andererseits die Magnetisierung des Kernstiftes ausbilden, gleichgepolt sein müssen, müssen die Magnete bei diesem Ausführungsbeispiel entgegengesetzt gepolt sein, damit der zweite Kernstift in seine Freigabestellung gebracht werden kann. Auch hier muss die Magnetkraft größer sein als die Kraft einer Rückstellfeder. Die Rückstellfeder beaufschlagt bei dieser Variante einen zweiten Gehäusestift, der in einer Gehäuseöffnung einliegt. Die Stirnfläche des zweiten Gehäusestiftes wird dabei von der Stirnfläche des Magnetstiftes beaufschlagt. Die Achse, entlang der sich der magnetische Zuhaltungsstift verlagern kann, hat in der Sperrstellung der Schließvorrichtung einen stumpfen Winkel zur Achse des zweiten Gehäusestiftes. Während die Achse des magnetischen Kernstiftes in der Sekantenebene liegt, liegt die Achse des mit dem Magnetstift zusammenwirkenden Gehäusestiftes in einer Radialebene. Die Bewegungsachse des zweiten Gehäusestiftes geht somit durch die Drehachse des Zylinderkerns. Der magnetische Kernstift kann einen durchmesserverminderten Abschnitt aufweisen. Dieser durchmesserverminderte Abschnitt kann in Richtung des Schlüsselkanals weisen und einen Permanentmagneten aufweisen. Der Permanentmagnet kann mit einer in Achsrichtung des magnetischen Kernstiftes gerichteten Polrichtung in einer Öffnung des Kernstiftes stecken. Die Magnetzone des Schlüsselschaftes wird von einem Permanentmagneten gebildet, dessen Polrichtung quer zur Schlüsselbreitseitenebene verläuft, also in der Ebenennormalen liegt. Der magnetische Kernstift ist undrehbar in seiner Lagerbohrung angeordnet. Die Lagerbohrung besitzt einen unrunden Querschnitt. Eine Querschnittsrandkante verläuft zunächst über mehr als 180 Grad auf einer Kreisbogenlinie. Unter Ausbildung von Knickpunkten bildet der Querschnittsrand eine Auswölbung aus. Die Auswölbung bildet eine Längsausnehmung, die unter Ausbildung einer Kante in einen auf einer Kreiszylinderinnenfläche verlaufenden Wandungsabschnitt der zweiten Kernbohrung übergeht. Der Kernstift besitzt einen Querschnitt, der ebenfalls einen sich über mehr als 180 Grad erstreckenden Randabschnitt besitzt, der auf einer Kreisbogenlinie verläuft. Von diesem Randabschnitt ragt ein Vorsprung ab, der eine Längsrippe bildet. Die Längsrippe liegt in der Längsausnehmung der Wandung der Kernbohrung. Es ist von besonderem Vorteil, wenn die Längsrippe beidseitig von Ausbuchtungen flankiert ist. Die Ausbuchtungen liegen dann den oben erwähnten Kanten gegenüber, so dass eine gerundete Flanke einer Kante gegenüberliegt. Hierdurch wird ein Verkanten des Kernstiftes in der Kernstiftbohrung vermieden. Die Ausbuchtungen erstrecken sich in Radialeinwärtsrichtung eines gedachten Kreises, in dem der sich über mehr als 180° erstreckende Randabschnitt verläuft. Ein mit dem Magnetstift zusammenwirkender zweiter Gehäusestift kann eine kreisrunde Zwischenfläche aufweisen und drehbar in seiner zugeordneten Gehäusebohrung liegen. Eine Schließvorrichtung gemäß der Erfindung kann eine Mehrzahl von Magnetstiften aufweisen. Jeder Magnetstift wirkt mit einer dem Schlüsselschaft zugeordneten Magnetzone zusammen. Es ist insbesondere vorgesehen, dass die Schließvorrichtung zumindest einen Magnetstift aufweist, der durch magnetische Abstoßung von der Magnetzone in eine Freigabestellung gebracht wird, und zumindest einen weiteren Magnetstift aufweist, der durch eine magnetische Anziehung durch die Magnetzone des Schlüsselschaftes in seine Freigabestellung bringbar ist. Die Gehäuseöffnung, in die der Magnetstift in seiner Sperrstellung eintaucht bzw. in der sich ein zweiter, mit dem Magnetstift zusammenwirkender Gehäusestift befindet, kann von einer Einsatzplatte ausgebildet sein. Besitzt der Schließzylinder mehrere Magnetstifte, so bildet die Einsatzplatte eine Mehrzahl von Öffnungen aus. Die Öffnungen können als Durchgangsbohrungen in der Einsatzplatte verwirklicht sein. Die Einsatzplatte steckt vorzugsweise in einer Ausnehmung der Wandung der Lagerhöhlung des Zylindergehäuses, in der der Zylinderkern drehbar gelagert ist. Die Einsatzplatte kann von der Stirnseite des Zylindergehäuses in die Ausnehmung eingeschoben sein. Die Längsrandseiten der Ausnehmung bzw. die Längsrandseiten der Einsatzplatte, die sich in Achsrichtung des Zylindergehäuses erstrecken, können sich in Querrichtung dazu in Radialrichtung erstrecken, so dass sich insgesamt eine schwalbenschwanzartige Struktur ausbildet, so dass die Einsatzplatte in Radialrichtung gefesselt ist. Die Böden der zweiten Gehäuseöffnungen werden von den Böden der Ausnehmung ausgebildet.A locking device according to the invention may have the following advantageous design features. The magnetic core pin overlapping second core hole is closed to the key channel blind hole. The bottom of the second core bore is thus permeable to the magnetic field of the magnetic core pin or the magnetic zone of the key shaft. The bottom of the blind bore forms a thin layer of material that separates the core bore from the keyway. Furthermore, a spring element may be provided be, with the magnetic core pin is acted upon in the direction of its blocking position. In the blocking position, a blocking section adjoining the end face of the magnetic tumbler pin projects into a housing opening. The obliquely extending end face then lies completely in the housing opening. The magnetic core pin is acted upon by a magnetic attraction through the magnetic zone of the key shaft against the restoring force of the spring element in the direction of its release position. The magnetic force is stronger than the spring force, so that the core pin can be brought by magnetic attraction against the restoring force of the spring element in the release position. Furthermore, it can be provided that the magnetic core pin interacts with a second housing pin acted upon in the direction of its blocking position by a prestressed spring element, which can be brought into a release position by magnetic repulsion of the magnetic core pin through the magnet zone against the restoring force of the spring element. While in the variant described above, the two magnets that form the magnetic zone on the one hand and on the other hand, the magnetization of the core pin must be gleichpolpolt, the magnets in this embodiment must be oppositely poled so that the second core pin can be brought into its release position. Again, the magnetic force must be greater than the force of a return spring. The return spring acts in this variant, a second housing pin, which rests in a housing opening. The end face of the second housing pin is acted upon by the end face of the magnetic pin. The axis along which the magnetic tumbler pin can move, in the blocking position of the locking device has an obtuse angle to the axis of the second housing pin. While the axis of the magnetic core pin is in the secant plane, the axis of the cooperating with the magnetic pin housing pin lies in a radial plane. The axis of movement of the second housing pin thus passes through the axis of rotation of the cylinder core. The magnetic core pin may have a reduced diameter portion. This reduced diameter Section may point in the direction of the key channel and have a permanent magnet. The permanent magnet can be stuck with an oriented in the axial direction of the magnetic core pin polar direction in an opening of the core pin. The magnetic zone of the key shank is formed by a permanent magnet whose polar direction runs transversely to the key broadside plane, that is, lies in the plane normal. The magnetic core pin is arranged non-rotatably in its bearing bore. The bearing bore has a non-circular cross-section. A cross-sectional edge initially runs over more than 180 degrees on a circular arc. By forming kink points of the cross-sectional edge forms a bulge. The bulge forms a longitudinal recess, which merges to form an edge in a running on a circular cylinder inner surface wall portion of the second core hole. The core pin has a cross-section which also has an edge portion extending over more than 180 degrees, which runs on a circular arc line. From this edge portion protrudes from a projection which forms a longitudinal rib. The longitudinal rib lies in the longitudinal recess of the wall of the core bore. It is particularly advantageous if the longitudinal rib is flanked on both sides by bulges. The bulges are then opposite the above-mentioned edges, so that a rounded edge of an edge opposite. This avoids tilting of the core pin in the core pin hole. The bulges extend in the radial inward direction of an imaginary circle, in which extends over more than 180 ° extending edge portion. A cooperating with the magnetic pin second housing pin may have a circular interface and rotatably lie in its associated housing bore. A closure device according to the invention may comprise a plurality of magnetic pins. Each magnetic pin cooperates with a magnetic zone associated with the key shaft. It is provided in particular that the closing device has at least one magnetic pin, which is brought by magnetic repulsion of the magnetic zone in a release position, and at least one further magnetic pin, which can be brought by a magnetic attraction through the magnetic zone of the key shaft in its release position. The housing opening into which the magnetic pin dips in its blocking position or in which there is a second, cooperating with the magnetic pin housing pin may be formed by an insert plate. If the lock cylinder has a plurality of magnetic pins, the insert plate forms a plurality of openings. The openings can be realized as through-holes in the insert plate. The insert plate is preferably inserted in a recess of the wall of the bearing cavity of the cylinder housing, in which the cylinder core is rotatably mounted. The insert plate can be inserted from the end face of the cylinder housing in the recess. The longitudinal edge sides of the recess or the longitudinal edge sides of the insert plate, which extend in the axial direction of the cylinder housing, may extend in the transverse direction thereto in the radial direction, so that a total dovetail-like structure is formed, so that the insert plate is tied in the radial direction. The bottoms of the second housing openings are formed by the bottoms of the recess.

Auf einer Stufe zwischen einem durchmessergrößeren und einem durchmesserkleinerem Abschnitt der Kernbohrung 14 stützt sich ein Ende einer Wendelgangdruckfeder ab. Das andere Ende der Wendelgangdruckfeder beaufschlagt eine Stufe, die von einem durchmessergrößeren Bereich des magnetischen Stiftes 13 ausgebildet wird.
