Description

Es zeigt 1 in einer Schemazeichnung ein Regelventil. In einem Gehäuse 14 mit einer kreisförmigen Polausbildung ist ein Permanentmagnet 15 in Ringform mit einer axialen Magnetisierung angeordnet. Ein Polende des Permanentmagneten hat Kontakt mit dem Gehäuse 14. Das andere Polende des Permanentmagneten wird mit dem Innenpol 13, der eine zylindrische Form aufweist, abgeschlossen. Zwischen dem Innenpol 13 und dem Gehäuse 14 befindet sich ein Luftspalt. Damit ist der magnetische Kreis vom Gehäuse 14 mit Polausbildung über den Luftspalt und dem Innenpol 13 geschlossen. Fixiert und zentriert wird der Innenpol 13 und der Permanentmagnet 15 mit Hilfe des Verbindungsteils 20. Das Verbindungsteil 20, ein magnetisch nicht leitendes Material, ist mit dem Gehäuse 14 verbunden. In diesem Luftspalt befindet sich ein Spulenkörper 10. Auf diesem Spulenkörper 10 ist eine Aktorwicklung 11 gewickelt. Auf dem Spulenkörper 10 sind isoliert von einander die Kontaktkörper 9 befestigt. An diesen Kontaktkörpern 9 sind die Stromzuführungsfedern 8 an einem Ende elektrisch leitend befestigt. Ebenfalls elektrisch leitend mit diesen Kontaktkörpern verbunden sind die Drahtenden der Aktorwicklung 11. Am anderen Stromzuführungsfederende 8 sind elektrisch leitend die Federkontakthalter 4 mit den Stromzuführungsfedern verbunden. Die Federkontakthalter 4 sind elektrisch voneinander isoliert an der Montageplatte 5 befestigt. Mit Hilfe des Abstandhalters 6 wird ein Abstand zwischen der Montageplatte 5 und dem Spulenkörper 10 hergestellt. Der Spulenkörper 10 wird mit Hilfe des Befestigungselements 7, z. B. eine Mutter, mit der Ventilnadel 1 verbunden. Ebenfalls mit der Ventilnadel 1 verbunden ist ein Sensorgeber 2. Dem Sensorgeber 2 gegenüber angeordnet ist der Sensor 3. Der Sensor 3 kann die Hubhöhe der Ventilnadel 1 erfassen. Die Ventilnadel 1 wird mit Hilfe der beiden Lager 12 gelagert.It shows 1 in a schematic drawing a control valve. In a housing 14 with a circular Polausbildung is a permanent magnet 15 arranged in ring form with an axial magnetization. A pole end of the permanent magnet is in contact with the housing 14 , The other pole end of the permanent magnet is connected to the inner pole 13 , which has a cylindrical shape, completed. Between the inner pole 13 and the housing 14 there is an air gap. This is the magnetic circuit from the housing 14 with Polausbildung on the air gap and the inner pole 13 closed. The inner pole is fixed and centered 13 and the permanent magnet 15 with the help of the connecting part 20 , The connecting part 20 , a magnetically non-conductive material, is integral with the housing 14 connected. In this air gap is a bobbin 10 , On this bobbin 10 is an actor development 11 wound. On the bobbin 10 are the contact bodies isolated from each other 9 attached. At these contact bodies 9 are the power supply springs 8th attached electrically conductive at one end. Also electrically connected to these contact bodies are the wire ends of the actuator winding 11 , At the other power supply spring end 8th are electrically conductive, the spring contact holder 4 connected to the power supply springs. The spring contact holder 4 are electrically isolated from each other on the mounting plate 5 attached. With the help of the spacer 6 is a distance between the mounting plate 5 and the bobbin 10 produced. The bobbin 10 is with the help of the fastener 7 , z. As a mother, with the valve needle 1 connected. Also with the valve needle 1 connected is a sensor concern 2 , The sensor concern 2 arranged opposite is the sensor 3 , The sensor 3 can the lifting height of the valve needle 1 to capture. The valve needle 1 is using the two bearings 12 stored.

Das Ventilgehäuse 18 ist z. B. mittels Schrauben mit dem Gehäuse 14 verbunden. Das Ventilgehäuse 18 hat einen Fluid- oder Pasteneinlass. Der Fluid- oder Pastenauslass geschieht mit Hilfe der Düse 19. In dieser Schemazeichnung hat die Düse 19 auch die Funktion eines Ventilsitzes. Eine Abdichtung des Ventilgehäuses 18 zum Gehäuse 14 wird mit Hilfe der Dichtung 17 erreicht.The valve housing 18 is z. B. by means of screws with the housing 14 connected. The valve housing 18 has a fluid or paste inlet. The fluid or paste outlet is done by means of the nozzle 19 , In this schematic drawing has the nozzle 19 also the function of a valve seat. A seal of the valve body 18 to the housing 14 is using the seal 17 reached.

Wird nun die Aktorwicklung 11 über die Federkontakthalter 4, den Stromzuführungsfedern 8 und den Kontaktkörpern 9 von einem elektrischen Strom durchflossen, bewegt sich je nach Stromrichtung die Ventilnadel 1 nach oben oder unten. Ebenfalls ist jede erdenkliche Hubhöhe der Ventilnadel zwischen dem oberen und unteren Schaltpunkt des Ventils je nach Stromstärke möglich. Dadurch wird erreicht, das ein Fluid oder eine Paste volumenmäßig kontrolliert ausgetragen werden kann. Ferner besteht auch die Möglichkeit gasförmige Stoffe auf die gleiche Art und Weise auszutragen.Will now the actuator winding 11 over the spring contact holder 4 , the power supply springs 8th and the contact bodies 9 traversed by an electric current moves depending on the direction of the valve needle 1 up or down. Also, every conceivable lifting height of the valve needle between the upper and lower switching point of the valve depending on the current is possible. This ensures that a fluid or a paste volume can be discharged controlled. Furthermore, it is also possible to discharge gaseous substances in the same way.

2 zeigt in einer Schemazeichnung eine Ausgestaltungsmöglichkeit. Die Düse 19 wird hier auf einen Ventilsitz 21 montiert. Der Ventilsitz 21 ist mit dem Ventilgehäuse 18 verbunden. Der Vorteil ist hier, dass der Anwender verschiedene Düsen, Düsennadeln oder Kanülen in verschiedenen Längen und Durchmessern schnell und einfach montieren kann. Hierbei braucht sich nicht die Länge oder der Durchmesser der Ventilnadel 1 zu ändern. 2 shows a design option in a schematic drawing. The nozzle 19 is here on a valve seat 21 assembled. The valve seat 21 is with the valve body 18 connected. The advantage here is that the user can assemble different nozzles, nozzle needles or cannulas in different lengths and diameters quickly and easily. This does not need the length or the diameter of the valve needle 1 to change.

Ebenso kann der Ventilsitz 21 zusammen mit dem Ventilgehäuse 18 eine Einheit bilden.Likewise, the valve seat 21 together with the valve body 18 form a unit.

3 zeigt in einer Schemazeichnung eine weitere Ausgestaltungsmöglichkeit. Das Fluid oder die Paste wird dem Ventilgehäuse 18 erwärmt zugeführt oder im Ventilgehäuse selbst mittels einer temperierten Wärmequelle 22 erwärmt. Anwendungen hierfür gibt es hierfür zum Beispiel in der Nahrungsmittelindustrie. 3 shows in a schematic drawing a further embodiment possibility. The fluid or paste becomes the valve body 18 heated supplied or in the valve housing itself by means of a temperature-controlled heat source 22 heated. There are applications for this purpose, for example in the food industry.

Die 4 zeigt eine andere Ausgestaltungsmöglichkeit. Zwischen dem Ventilgehäuse 18 und dem Gehäuse 14 ist eine thermische Isolierung 23 angebracht. Siehe auch Patent „Ventil mit thermischer Isolierung”. Mit Hilfe dieser thermischen Isolierung wird in dieser Ausgestaltungsmöglichkeit verhindert, dass die vom Fluid oder von der separaten Wärmequelle gelieferte Energie nach oben zum Aktor transportiert wird. Empfindliche Aktorteile werden dadurch in ihren mechanischen und elektrischen Eigenschaften kaum verändert. Diese Anordnung ermöglicht auch eine Anwendung im höheren Temperaturbereich.The 4 shows another embodiment possibility. Between the valve body 18 and the housing 14 is a thermal insulation 23 appropriate. See also patent "Valve with thermal insulation". With the help of this thermal insulation is prevented in this embodiment possibility that the energy supplied by the fluid or by the separate heat source is transported up to the actuator. Sensitive actuator parts are thus hardly changed in their mechanical and electrical properties. This arrangement also allows application in the higher temperature range.

Die 5 zeigt eine weitere Ausgestaltungsmöglichkeit. Hier wird ein ringförmiger Magnet 15 mit einer radialen Magnetisierungsrichtung verwendet. Dieser wird außen zur Erhöhung der Magnetfläche angeordnet. Der Magnet 15 ist mit dem Gehäuse 14 magnetisch leitend verbunden. In diesem Fall übernimmt dann das Gehäuse 14 die Funktion des Innen- und Außenpols. Selbstverständlich könnte der Magnet auch innen angeordnet werden.The 5 shows a further embodiment possibility. Here is an annular magnet 15 used with a radial magnetization direction. This is arranged outside to increase the magnetic surface. The magnet 15 is with the case 14 connected magnetically. In this case, then takes over the housing 14 the function of the inner and outer pole. Of course, the magnet could also be arranged inside.

Durch diese Konstruktionsanordnung ist eine sehr kurze Aktorbauhöhe möglich.By this construction arrangement a very short Aktorbauhöhe is possible.

Ebenfalls denkbar sind auch mehrere Aktoren, die gleichzeitig die Ventilnadel 1 antreiben.Also conceivable are several actuators, the same time the valve needle 1 drive.

Denkbar ist auch ein Aktor, der die Ventilnadel nach oben treibt und ein zweiter Aktor, der die Ventilnadel nach unten bewegt.It is also conceivable an actuator, which drives the valve needle upwards and a second actuator, which moves the valve needle down.

Vorteileadvantages

Die Erfindung insbesondere in Form eines Regelventils für Fluide und Pasten betrifft einen Gegenstand mit einem Kurzhubaktor und einer Tauchspule.The invention in particular in the form of a control valve for fluids and pastes relates to an article with a Kurzhubaktor and a plunger coil.

Es ist bekannt, Ventile mit einem Stößel, der als Hubanker funktioniert und einer Magnetspule herzustellen. Hierbei ist der grundsätzliche Nachteil das nichtlineare Verhalten zwischen der Kraft und dem Hub. Ein weiterer Nachteil sind die geringen Schaltzeiten bis zu 100 ms. Hiermit ist ein Regelventil nicht zu realisieren. Diese eignen sich deshalb auch nur für Schaltventile.It is known to produce valves with a plunger that works as a lifting armature and a solenoid. Here, the fundamental disadvantage is the non-linear behavior between the force and the stroke. Another disadvantage is the low switching times up to 100 ms. This is not a control valve to realize. These are therefore only suitable for switching valves.

Weiterhin ist bekannt, Regelventile mit einem Solenoid-Aktor herzustellen. Nach dem Solenoid-Prinzip arbeitende Aktoren erreichen nach dem momentanen Stand der Technik maximal Schaltfrequenzen bis zu 5 ms mit relativ großen Hüben.Furthermore, it is known to produce control valves with a solenoid actuator. According to the current state of the art, actuators operating according to the solenoid principle achieve maximum switching frequencies of up to 5 ms with relatively large strokes.

Bekannt sind auch pneumatische oder elektropneumatische Schaltventile oder Regelventile. Alle benötigen Druckluft als weitere Energiequelle. Die Schaltzeiten liegen zwischen einigen 10 ms bis hin zu einigen 100 ms.Also known are pneumatic or electropneumatic switching valves or control valves. All require compressed air as another energy source. The switching times are between a few 10 ms and several 100 ms.

Es ist auch bekannt, Ventile in Piezo-Technik herzustellen. Diese Ventile haben eine hohe Dynamik und eine sehr gute Regelbarkeit. Auch weisen diese Ventile eine gute Systemsteifigkeit. Für den industriellen Einsatz ergeben sich leider Nachteile in Bezug auf die Auslenkung. Auslenkungen bis zu 0,3 mm sind das absolute Maximum. Leider ist dies mit einem großen Bauvolumen (Höhe des Piezostapels) und einer geringen Auslassmenge verbunden. Eine Lösung wäre es, mit Hebelübersetzungen zu arbeiten. Dies führt jedoch zu einem Dynamikverlust. Deren Einsatzgebiet ist z. B. die Automobiltechnik.It is also known to produce valves in piezo technology. These valves have a high dynamics and a very good controllability. Also, these valves have a good system stiffness. For industrial use, unfortunately, there are disadvantages with respect to the deflection. Deflections up to 0.3 mm are the absolute maximum. Unfortunately, this is associated with a large volume of construction (height of the piezo stack) and a small outlet volume. One solution would be to work with leverage. However, this leads to a loss of dynamics. Their application is z. B. the automotive industry.

Bekannt sind auch Tauchspulaktoren mit einer langen Tauchspule. Diese erreichen Schaltzeiten von bis zu 4 ms. Eingesetzt werden diese Aktoren überwiegend dort, wo längere Hübe mit einer geringen Eigenbeschleunigung vertretbar sind. Beispiele hierfür sind z. B. Gasdruckregler oder Linearaktoren. Als Nachteil erweist sich die Energiezuführung auf die sich bewegende Spule. In vielen Fällen erfolgt dies direkt über ein flexibles Kabel. Das flexible Kabel ist hierbei eine zusätzliche Störquelle und führt oft zum Ausfall des Aktors.Also known are Tauchspulaktoren with a long plunger coil. These achieve switching times of up to 4 ms. These actuators are mainly used where longer strokes with a low self-acceleration are acceptable. Examples are z. B. gas pressure regulator or linear actuators. The disadvantage is the energy supply to the moving coil. In many cases, this is done directly via a flexible cable. The flexible cable is an additional source of interference and often leads to failure of the actuator.

Es ist die Aufgabe der Erfindung, ein Regelventil so zu verbessern, das eine größere Beschleunigung erreicht und gleichermaßen das austretende Fluid- oder Pastenvolumen nicht reduziert wird. Ferner ist es die Aufgabe der Erfindung die Energiezuführung zu verbessern.It is the object of the invention to improve a control valve so that reaches a greater acceleration and equally the exiting fluid or paste volume is not reduced. Furthermore, it is the object of the invention to improve the energy supply.

Erfindungsgemäß erfolgt die Lösung der Aufgabe dadurch, dass eine Tauchspule mit einer kurzen Spule verwendet wird. Da der Hub oder die Wegstrecke relativ kurz ausgeführt sein müssen, kann auch die Aktor oder Tauchspule mit einer geringen Bauhöhe hergestellt werden. Hierbei ist die Masse des Wickeldrahtes klein und das gesamte Wickelvolumen der Aktorspule befindet sich im Magnetfeld. Dadurch ist eine sehr hohe Eigenbeschleunigungen möglich. Dies hat eine kleine mechanische Zeitkonstante zur Folge und damit sehr kurze Schaltzeiten. Die Schaltzeiten betragen je nach Konstruktion, Stromstärke und Spannung nur bis zu 0,5 ms.According to the invention, the object is achieved in that a plunger coil is used with a short coil. Since the stroke or the distance must be made relatively short, the actuator or plunger coil can be made with a low height. Here, the mass of the winding wire is small and the entire winding volume of the actuator coil is in the magnetic field. As a result, a very high self-acceleration is possible. This results in a small mechanical time constant and thus very short switching times. Depending on the design, current and voltage, the switching times are only up to 0.5 ms.

Ferner liefert die Tauchspule mit kurzer Spule bessere Ergebnisse in Bezug auf eine Zusatzgröße bzw. Masse, z. B. höherer Fluiddruck, Fluide mit einer höheren Viskosität oder eine Masseerhöhung der Ventilnadel (Erhöhung des Durchmessers), zur Beschleunigung.Furthermore, the short coil plunger coil gives better results in terms of extra size or mass, e.g. B. higher fluid pressure, fluids with a higher viscosity or an increase in mass of the valve needle (increase the diameter), for acceleration.

Eine weitere Konstruktionsverbesserung wird durch die beiden Stromzuführungsfedern erreicht. Die Aufgabe der Stromzuführungsfedern ist es zum Einen den notwendigen Strom für die Aktorspule zu transportieren, zum Anderen wird dadurch die Ventilrückstellung erreicht.Another design improvement is achieved by the two power supply springs. The task of the power supply springs is to transport the necessary current for the actuator coil on the one hand, on the other hand, the valve reset is achieved.

Damit ist ein hochdynamisches, in Verbindung mit zum Beispiel einem Sensor, regelbares System realisiert.This is a highly dynamic, realized in conjunction with, for example, a sensor, adjustable system.

Dadurch ist es möglich, flüssige oder pastöse Stoffe mit einer sehr hohen Viskosität sehr schnell zu regeln oder zu schalten, wobei gleichzeitig das maximale austretende Fluid- oder Pastenvolumen nicht reduziert wird. Denkbar ist auch der Einsatz im höheren Temperaturbereich, wenn weitere konstruktive Maßnahmen ergriffen werden.This makes it possible to regulate or switch liquid or pasty substances with a very high viscosity very rapidly, while at the same time the maximum leaving fluid or paste volume is not reduced. Also conceivable is the use in the higher temperature range, if further design measures are taken.
