Description

Die Erfindung bezieht sich auf magnetelektrische Zündapparate derjenigen Art, bei der der Rotor wenigstens vier Pole besitzt, die sich gleichzeitig vor einer gleichen Anzahl von Polen des Stators befinden können. Sie hat eine besondere Ausbildung des magnetischen Kreises bei solchen magnetelektrischen Zündapparaten zum Gegenstand, um eine Trennung zwischen den elektrischen und den mechanischen Organen zu bewerkstelligen und den Apparat leicht auseinandernehmbar zu machen.The invention relates to magneto-electric igniters of the kind at that the rotor has at least four poles that are at the same time in front of an equal number from poles of the stator can be located. She has a special magnetic training Circle in such magneto-electric ignition apparatus to the object to a separation between the electrical and the to accomplish mechanical organs and the apparatus easily dismantled close.

Bei magnetelektrischen Zündapparaten der angegebenen Art ist bereits vorgeschlagen worden, den umlaufenden Magnet in leicht zugängiger Lage zwischen den Polstücken anzubringen; indes wird in diesem Fall die Wicklung von dem magnetischen Kreis umgeben. Weiterhin ist schon vorgeschlagen worden, die Wicklung außerhalb des magnetischen Kreises anzuordnen. Bei den bekannten Konstruktionen dieser Art wird jedoch der Magnet von dem magnetischen Kreis eingeschlossen.In the case of magneto-electric ignition apparatus of the type specified, this has already been proposed the rotating magnet in an easily accessible position between the pole pieces to attach; however, in this case the winding is surrounded by the magnetic circuit. Furthermore, it has already been proposed that the winding outside the magnetic To arrange a circle. In the known constructions of this type, however, the magnet is from the magnetic Circle included.

Gemäß der Erfindung sind nun die Teile des Stators, wo sich die gleichnamigen Pole bilden, untereinander durch Stücke verbunden, die sich hinsichtlich des umlaufenden Organs auf derselben Seite befinden. Auf diese Weise werden die mechanischen Organe von dem elektrischen Teil des Apparats getrennt, und das umlaufende Organ wird nicht von dem magnetischen Kreis umschlossen und bleibt immer leicht zugängig.According to the invention, the parts of the stator where the poles of the same name are located are now form, connected to one another by pieces that are related to the circumferential Organ are on the same side. This is how the mechanical organs become separated from the electrical part of the apparatus, and the orbiting organ will not enclosed by the magnetic circuit and always remains easily accessible.

Auf der Zeichnung ist eine Ausführungsform des Gegenstandes der Erfindung für den Fall eines Zündmagnets mit vier Polen und mit umlaufendem Sternmagnet beispielsweise dargestellt. Es zeigen:In the drawing is an embodiment of the subject matter of the invention for Case of an ignition magnet with four poles and a rotating star magnet, for example shown. Show it:

In Fig. ι bezeichnet 1 einen Magnet mit vier Polen, der drehbar in einem Stator angeordnet ist, dessen zwei Paare von gleichnamigen Polen mit 2, 2' bezeichnet sind. 3 ist die Wicklung, deren Kern 4 mit zwei Armen 5 und s' verbunden ist, welche unmittelbar mittels schematisch durch die Linie 6, 6' angegebener Verbindungsstege mit den oberen beiden Polen 2, 2' verbunden sind.In Fig. Ι 1 denotes a magnet four poles, which is rotatably arranged in a stator, whose two pairs of the same name Poles are designated by 2, 2 '. 3 is the winding, the core of which is 4 with two arms 5 and s 'is connected, which is indicated directly by means of schematically indicated by the line 6, 6' Connecting webs are connected to the upper two poles 2, 2 '.

Die unteren Pole 2, 2' des Stators sind ebenfalls mit den Armen 5, 5' verbunden, undThe lower poles 2, 2 'of the stator are also connected to the arms 5, 5', and

Claims

by means of webs indicated by the line 7, j ' and by the arms 8, 8'.

The device described can practically be carried out according to FIGS. 2 to 4, ;;, in which 1 also has the circumferential M- ' gnet denotes who determined one. axial part of the pole lugs 2, 2 'of the stator? ·' (Fig. 2) and is arranged on a shaft 9, which is suitable in any

10 'way by means of bearings 10 in the housing 11 of the apparatus is stored.

The stator consists of two pairs of parallel, leafed pieces that form the Form poles between which the magnet 1 rotates, and of which the upper poles 2.2 ' extend laterally to form the arms 5, 5 'that connect to the ends of the core 4 are connected.

The leafed webs 2, 2 'extend in the axial direction of the shaft 9 a certain Distance beyond the length of the rotating magnet 1, and on this Track is attached to each part 2, 2 'a traverse 12, 12', which on its opposite End connected to the opposite pole 2, 2 'of the same name (Figures 2 and 4).

With the help of these trusses 12, 12 'are the lower poles 2, 2 'connected to arms 5, 5' via the upper poles, and onto these So all poles of the same name are connected with the same arm.

The traverses 12, 12 'are both located on the same end of the space bounded by poles 2, 2 'and on the same side with regard to the magnet 1, so that this is not completely enclosed in the magnetic circuit and is easily removed can be.

In the embodiment shown, the cross members 12, 12 'consist of peeled connecting webs. These connecting webs cross in the space between the poles 2, 2 ' and are consequently with holes _; \ ^f jirsehen to allow wave 9 passage.

Instead of four poles, the system can contain a larger number of poles, and in this case, the number of trusses 12, 12 'is greater than 2, i.e. it corresponds to half the Pohl number.
