Description

Elektromagnetisch betätigte Stellvorrichtung Die Erfindung betrifft eine elektromagnetisch betätigte Stellvorrichtung, die für Ventile und andere Regelglieder verwendet werden soll und die mit einem an einem Stellschaft angebrachten Magnetanker versehen ist, auf den wahlweise einschaltbare elektromagnetische Stellkräfte einwirken. Solche Stellvorrichtungen dienen in bekannter Weise dazu, ein Ventil oder ein Regelglied beim Einschalten der elektromagnetischen Stellkraft von einer Endstellung in die andere zu bringen.Electromagnetically Operated Actuator The invention relates to an electromagnetically operated control device for valves and other control elements to be used and those with a magnet armature attached to a society is provided, acting on the optionally switchable electromagnetic actuating forces. Such adjusting devices are used in a known manner to control a valve or a control element when switching on the electromagnetic actuating force from one end position to the bring others.

Es ist ferner bekannt, mit dem Stehschaft einer Stellvorrichtung eine hydraulische Bremsvorrichtung zu verbinden, bei der durch einen Kolben Bremsflüssigkeit von einem Zylinderraum in den anderen unter Drosselung verdrängt wird, um eine Dämpfung der Stellbewegung zu erreichen.It is also known to use the standing shaft of an adjusting device to connect hydraulic braking device, in which brake fluid through a piston is displaced from one cylinder chamber to the other with throttling, in order to dampen to achieve the adjusting movement.

Die Erfindung besteht darin, daß in eine Verbindungsleitung der beiden Zylinderräume ein Absperrorgan eingebaut ist, das während der Einschaltdauer der magnetischen Stellkraft selbsttätig offengehalten wird. Dadurch wird es möglich, durch eine impulsartige Einschaltung der elektromagnetischen Stellkräfte eine definierte schrittweise Stellbewegung herbeizuführen, um das Ventil oder das sonstige Regelglied elektromagnetisch in beliebige Zwischenstellungen zu bringen und in diesen hydraulisch zu arretieren.The invention consists in that in a connecting line of the two A shut-off device is installed in the cylinder chambers, which is activated during the switch-on period of the magnetic actuating force is kept open automatically. This makes it possible a defined pulse-like activation of the electromagnetic actuating forces gradually bring about adjusting movement to the valve or other control element to bring electromagnetically into any intermediate positions and in these hydraulically to lock.

Es sind sogenannte Schwingankerventile bekannt, bei denen eine plötzliche Auf- und Zuschaltung durch Federn in Verbindung mit in beiden Richtungen wirkenden Haltemagneten erreicht wird. Eine schrittweise Stellbewegung mit Zwischenstellungen ist dabei nicht möglich und auch nicht vorgesehen.So-called oscillating armature valves are known in which a sudden Activation and activation by springs in connection with acting in both directions Holding magnet is reached. A step-by-step positioning movement with intermediate positions is not possible and not intended.

Zweckmäßigerweise wird die Stellvorrichtung nach der Erfindung so ausgebildet, daß zwei auf den Magnetkern in entgegengesetzten Richtungen wirkende Hubmagnetspulen wahlweise einschaltbar sind. Man erreicht dadurch, daß bei beiden Stellrichtungen definierte, z. B. gleiche Stellkräfte am Anker des Stellschaftes wirksam sind.The adjusting device according to the invention is expediently so designed that two acting on the magnetic core in opposite directions Solenoid coils can be switched on optionally. One achieves that with both Adjusting directions defined, z. B. same actuating forces at the anchor of the company are effective.

Vorteilhafterweise ist das Absperrorgan als ein Magnetventil ausgebildet, das zugleich mit der auf den Magnetanker einwirkenden elektromagnetischen Stellkraft ein- und ausschaltbar ist.The shut-off element is advantageously designed as a solenoid valve, this at the same time as the electromagnetic actuating force acting on the armature can be switched on and off.

Ein Ausführungsbeispiel Stellvorrichtung nach der Erfindung wird an Hand der Zeichnung erläutert. In eine Leitung 5 ist ein Regelglied A eingeschaltet, das durch eine elektromagnetische Stellvorrichtung B betätigt wird. Mit der Stellvorrichtung B ist eine hydraulische Brems- und Arretiervorrichtung C verbunden.An embodiment of the adjusting device according to the invention is shown on Hand of drawing explained. A control element A is switched on in a line 5, which is operated by an electromagnetic actuator B. With the adjusting device B, a hydraulic braking and locking device C is connected.

Am Stehschaft 4 ist ein Magnetkern 3 angebracht, der mit zwei getrennt schaltbaren Magnetspulen 1, 2 zusammenarbeitet. Bei Erregung der Magnetspule 1 wird der Magnetkern 3 nach oben und bei Erregung der Magnetspule 2 nach unten gezogen. Die Magnetspulen 1, 2 können einzeln abgestimmt werden, so daß sie genau gleiche oder auch in definierter Weise ungleiche Kräfte auf den Magnetkern 3 ausüben.A magnetic core 3 is attached to the upright shaft 4 and works together with two separately switchable magnetic coils 1, 2. When the magnet coil 1 is excited, the magnet core 3 is pulled upwards and when the magnet coil 2 is excited it is pulled downwards. The magnet coils 1, 2 can be tuned individually so that they exert exactly the same or, in a defined manner, unequal forces on the magnet core 3.

Mit dem Stehschaft 4 ist ein Kolben 6 verbunden, der abdichtend in einem mit Bremsflüssigkeit gefüllten Bremszylinder 10 gleitet. Bei jeder Bewegung verdrängt der Kolben 6 über eine Verbindungsleitung 9 die Bremsflüssigkeit von einem Zylinderraum in den anderen. In der Verbindungsleitung 9 befindet sich eine einstellbare Drosselstelle 8 sowie ein von einem Elektromagneten 11 gesteuertes Absperrventil 7.A piston 6 is connected to the upright shaft 4 and slides in a sealing manner in a brake cylinder 10 filled with brake fluid. With each movement, the piston 6 displaces the brake fluid from one cylinder chamber into the other via a connecting line 9. In the connecting line 9 there is an adjustable throttle point 8 as well as a shut-off valve 7 controlled by an electromagnet 11.

Durch einen Schalter 12 kann zugleich die Magnetspule 2 und der Magnet 11 eingeschaltet werden. Der Magnetkern 3 wird daher nach unten gezogen und kann auch der auf ihn wirkenden magnetischen Kraft nachgeben, da das Absperrventil 7 durch den Magneten 11 geöffnet ist, so daß eine Verdrängung von Bremsflüssigkeit erfolgen kann. Sobald der Schalter 12 geöffnet wird, schließt das Absperrventil 7, so daß der Stehschaft 4 in der erreichten Stellung hydraulisch arretiert ist. Wird der Schalter 13 geschlossen, so wird mit der Erregung der Magnetspule 1 wieder das Absperrventil 7 durch den Magneten 11 für die Dauer der Magneterregung geöffnet, so daß der Stellschaft 4 nach oben bewegt werden kann, bis er durch Öffnen des Schalters 13 wieder in der jetzigen Stellung hydraulisch verriegelt ist. The magnet coil 2 and the magnet 11 can be switched on at the same time by a switch 12. The magnetic core 3 is therefore pulled down and can also yield to the magnetic force acting on it, since the shut-off valve 7 is opened by the magnet 11, so that brake fluid can be displaced. As soon as the switch 12 is opened, the shut-off valve 7 closes so that the standing shaft 4 is hydraulically locked in the position it has reached. If the switch 13 is closed, the shut-off valve 7 is opened again by the magnet 11 for the duration of the magnet excitation with the excitation of the solenoid coil 1, so that the company 4 can be moved upwards until it is in the again by opening the switch 13 current position is hydraulically locked.
