ElektromagnetantriebElectromagnetic drive

BeschreibungDescription

Die Erfindung betrifft einen Elektromagnetantrieb insbesondere zur leistungsarmen Ansteuerung fluidischer Stelleinrichtungen wie Kleinventile und dergleichen. The invention relates to an electromagnetic drive, in particular for the low-power control of fluidic actuating devices such as small valves and the like.

Die Forderung nach leistungsarmen Ansteuerungen für Stellantriebe resultiert u.a. aus der Entwicklung der Bustechnik und dem Wunsch der Entnahme der elektrischen Energie direkt aus dem Bus sowie der Erfüllung von Forderungen an den Einsatz dieser Antriebe in explosionsgefährdeter Umgebung.The demand for low-power controls for actuators results, among other things, from the development of bus technology and the desire to take electrical energy directly from the bus, as well as to meet requirements for the use of these drives in potentially explosive environments.

Die Lösung dieser Aufgabe ergibt sich aus den beigefügten Schutzansprüchen.The solution to this problem arises from the attached claims.

Eine vorteilhafte Ausführungsform ist in Fig. 1 gezeigt.An advantageous embodiment is shown in Fig. 1.

Nach Fig. 1 ist der Elektromagnetantrieb mit einem Topfmagnet versehen, dessen Ankerplatte (2) mit einem Rückstellelement (Feder) (3) gekoppelt ist. Der Kern (4) des Magneten ist zur Verbesserung des magentischen Flusses mit einem Kragen (5) versehen. Zur weiteren Formung des magnetischen Flusses kann ein Flußleitstück (6) eingesetzt werden. Die Magnetspulen (7) können bei der Lösung nach Figur 1 direkt auf den Kern (4) gewickelt werden. Die Einheit Feder/Ankerplatte steuert die Düsen der Anschlüsse P und R, bei A ist der Ventilausgang angeordnet.According to Fig. 1, the electromagnet drive is provided with a pot magnet, the armature plate (2) of which is coupled to a return element (spring) (3). The core (4) of the magnet is provided with a collar (5) to improve the magnetic flux. A flux guide (6) can be used to further shape the magnetic flux. The magnetic coils (7) can be wound directly onto the core (4) in the solution according to Fig. 1. The spring/armature plate unit controls the nozzles of connections P and R, and the valve outlet is located at A.
