Description

Die Erfindung betrifft ein Ausbringgerät für Sicherheitsflüssigkeiten wie flüssige Lösungen von Reizmitteln wie Oleoresin Capsicum, Fluchtmittel wie eine Kombination aus (E)-2-Butenylmercaptan (C4H7SH), 3-Methylbutanthiol und den entsprechenden S-Acetyl-Verbindungen, Markierstoffe wie Farben und fluoreszierende Pigmente, Kombinationen der Vorgenannten und Löschmittel zur Brand- und Brandfrühbekämpfung wie 1, 1, 1, 2, 2, 4, 5, 5, 5-Nonafluor-4-(trifluormethyl)- 3-pentanon, bekannt als Novec™ 1230 von 3M™, insbesondere in technischen Einrichtungen, wie z.B. Schaltschränken, mit einem an eine Sicherheitsflüssigkeitsquelle angeschlossenen Ventil, das in einen Verteiler mit Ausbringöffnungen mündet, Ferner kann das Ausbringgerät noch eine Steuereinrichtung zur Freisetzung der Sicherheitsflüssigkeit enthalten.The invention relates to a dispenser for safety fluids such as liquid solutions of irritants such as oleoresin capsicum, escape agents such as a combination of (E) -2-butenylmercaptan (C4H7SH), 3-methylbutanethiol and the corresponding S-acetyl compounds, markers such as dyes and fluorescent pigments Combinations of the foregoing and fire and fire extinguishing agents such as 1, 1, 1, 2, 2, 4, 5, 5, 5-nonafluoro-4- (trifluoromethyl) -3-pentanone, known as Novec ™ 1230 from 3M ™ , in particular in technical facilities, such as Switch cabinets, with a valve connected to a safety fluid source, which opens into a distributor with Ausbringöffnungen, Furthermore, the dispenser may also contain a control device for releasing the safety fluid.

Um eine bestimmte Konzentration an Sicherheitsflüssigkeit in einem entsprechenden Zeitraum aufzubauen, werden derzeit Düsen verschiedenster Bauart verwendet, denen die Sicherheitsflüssigkeit mittels eines unter Druck stehenden Rohrleistungssystems zugeführt wird. Unvorteilhafterweise steigt bei dieser Methode die Partikelgröße des Sicherheitsflüssigkeitsnebels und die Ausbringzeit der Sicherheitsflüssigkeit mit fallendem Systemdruck. Zum Erreichen des notwendigen Drucks kommen derzeit einerseits verschiedene Treibmittel wie CO2, Argon, N2 etc. zum Einsatz, die in entsprechender Menge und unter entsprechendem Druck in Druckbehältern gelagert sein müssen, andererseits Druckerhöhungspumpen.In order to build up a certain concentration of safety fluid in a corresponding period, currently nozzles of various types are used, to which the safety fluid is supplied by means of a pressurized tube power system. Unfortunately, this method increases the particle size of the safety fluid mist and the delivery time of the safety fluid with decreasing system pressure. To achieve the necessary pressure currently come on the one hand different propellants such as CO 2 , argon, N 2, etc. are used, which must be stored in appropriate quantities and under appropriate pressure in pressure vessels, on the other hand pressure booster pumps.

Ein Ausbringgerät für Flüssigkeiten mit den in Oberbegrift des Anspruchs 1 genannten Merkmalen ist aus US 2002/0148908 A1 bekannt.A dispensing device for liquids with the features mentioned in the preamble of claim 1 is made US 2002/0148908 A1 known.

Aufgabe der vorliegenden Erfindung ist es ein Ausbringgerät zu schaffen, mit dem möglichst ohne Verwendung von Treibmitteln oder Druckerhöhungspumpen Sicherheitsflüssigkeit ausgebracht und unter rascher Verdampfung mit geringsten Tropfenflugwegen zerstäubt werden kann und mit der rasch die erforderliche Konzentration an Sicherheitsflüssigkeit aufgebaut werden kann.The object of the present invention is to provide a dispensing device, with which as far as possible without the use of propellants or booster pump safety fluid can be applied and atomized with rapid evaporation with the lowest drop flight paths and can be quickly built with the required concentration of safety fluid.

Die Aufgabe wird durch ein Ausbringgerät gemäß Anspruch 1 gelöst.The object is achieved by a dispensing device according to claim 1.

Durch die Drehung des Zerstäuberrades wird die Sicherheitsflüssigkeit weggeschleudert und es wird ein Unterdruck erzeugt, der die Sicherheitsflüssigkeit von der Sicherheitsflüssigkeitsquelle, z.B. aus einem Bevorratungsbehälter, saugt.By the rotation of the atomizer wheel, the safety liquid is thrown away and a negative pressure is generated which releases the safety fluid from the safety fluid source, e.g. from a storage container, sucks.

Sicherheitsflüssigkeitsquelle ist über einen Flüssigkeitskanal im Ventil mit dem Zerstäuberrad verbunden und das Ventil weist einen Lufteintrittskanal auf, der gegenüber dem Flüssigkeitskanal abgedichtet ist. Durch den Lufteintrittskanal kann Luft zur Sicherheitsflüssigkeitsquelle nachströmen und ein Druckausgleich wird ermöglicht. Durch die Verwendung des Zerstäuberrades wird die Sicherheitsflüssigkeit durch Zentrifugalkraft beschleunigt und mit hoher Geschwindigkeit in die Umgebungsatmosphäre eingebracht. Dadurch erfolgt eine rasche, gleichförmige Erhöhung der Sicherheitsflüssigkeitskonzentration in der Umgebungsatmosphäre.Safety fluid source is connected to the atomizer wheel via a fluid channel in the valve and the valve has an air inlet channel which is sealed off from the fluid channel. Air can flow in through the air inlet channel to the safety fluid source and pressure equalization is made possible. By using the atomizer wheel, the safety liquid is accelerated by centrifugal force and introduced at high speed into the ambient atmosphere. This results in a rapid, uniform increase in the safety fluid concentration in the ambient atmosphere.

Um eine bessere Zerstäubung und eine bessere Durchmischung von Sicherheitsflüssigkeit und Luft zu erreichen, ist vorteilhafter Weise um den Umfang des Zerstäuberrades eine Prallfläche vorgesehen, die vorzugsweise gegenüber der Drehachse des Zerstäuberrades geneigt ist.In order to achieve a better atomization and a better mixing of safety liquid and air, an impact surface is advantageously provided around the circumference of the atomizer, which is preferably inclined relative to the axis of rotation of the atomizer wheel.

Das ist Ventil ein Schieberventil mit einem Ventilkolben und einem Ventilkörper, das im geschlossenen Zustand den Sicherheitsflüssigkeitsaustrittskanal und den Lufteintrittskanal verschließt und im geöffneten Zustand den Sicherheitsflüssigkeitsaustrittskanal mit dem Zerstäuberrad verbindet und den Lufteintrittskanal mit der Atmosphäre verbindet. Das Schieberventil kann bei hoher Dichtheit einfach mechanisch, elektrisch, elektromechanisch, pneumatisch, hydraulisch oder pyrotechnisch betätigt werden.This valve is a slide valve with a valve piston and a valve body which, in the closed state, closes the safety fluid outlet channel and the air inlet channel and in the opened state connects the safety fluid outlet channel with the atomizer wheel and connects the air inlet channel to the atmosphere. The slide valve can be easily mechanically, electrically, electromechanically, pneumatically, hydraulically or pyrotechnically operated at high tightness.

Im Zerstäuberrad kann ein Auflaufelement vorgesehen sein, das mit einer Auflauffläche am Ventilkolben zusammenwirkt, um diesen bei Drehung des Zerstäuberrades zu verschieben. So kann durch die Drehung des Zerstäuberrades nicht nur die Sicherheitsflüssigkeit ausgebracht und der erforderlich Unterdruck erzeugt werden, sondern auch das Ventil geöffnet werden.In the Zerstäuberrad a run-up element may be provided which cooperates with a ramp surface on the valve piston to move it upon rotation of the Zerstäuberrades. Thus, not only the safety fluid can be discharged and the required negative pressure generated by the rotation of the atomizer, but also the valve can be opened.

In einer bevorzugten Ausführungsform enthält das Zerstäuberrad ein Auslöseelement mit Klauenfunktion, das mit einer Freistellung am Ventilkolben zusammenwirkt, um diesen bei Drehung des Zerstäuberrades durch Federkraft zu verschieben. So kann durch die Drehung des Zerstäuberrades nicht nur die Sicherheitsflüssigkeit ausgebracht und der erforderlich Unterdruck erzeugt werden, sondern auch das Ventil geöffnet werden.In a preferred embodiment, the Zerstäuberrad contains a trigger element with claw function, which cooperates with an exemption on the valve piston to move it by rotation of the Zerstäuberrades by spring force. Thus, not only the safety fluid can be discharged and the required negative pressure generated by the rotation of the atomizer, but also the valve can be opened.

In einer bevorzugten Ausführungsform enthält das erfindungsgemäße Ausbringgerät einen Elektromotor zur Drehung des Zerstäuberrades.In a preferred embodiment, the dispensing device according to the invention comprises an electric motor for rotating the Zerstäuberrades.

In einer bevorzugten Ausführungsform enthält das erfindungsgemäße Ausbringgerät eine Sicherheitsflüssigkeitsfüllstandsüberwachungseinrichtung.In a preferred embodiment, the dispensing device according to the invention contains a safety fluid level monitoring device.

In einer bevorzugten Ausführungsform kommt als Sicherheitsflüssigkeit das Löschmittel Novec™ 1230 von 3M™ zum Einsatz.In a preferred embodiment, the safety fluid used is the extinguishing agent Novec ™ 1230 from 3M ™.

In einer bevorzugten Ausführungsform können als Sicherheitsflüssigkeit eine flüssige Lösung von Reizmitteln wie Oleoresin Capsicum, Fluchtmittel wie eine Kombination aus (E)-2-Butenylmercaptan (C4H7SH), 3-Methylbutanthiol und den entsprechenden S-Acetyl-Verbindungen, Markierstoffe wie Farben und fluoreszierende Pigmente oder eine Kombination der Vorgenannten zum Einsatz kommen.In a preferred embodiment, a liquid solution of irritants such as oleoresin capsicum, escape agents such as a combination of (E) -2-butenylmercaptan (C4H7SH), 3-methylbutanethiol and the corresponding S-acetyl compounds, markers such as dyes and fluorescent pigments can be used as the safety fluid or a combination of the above are used.

Im in Fig.1 bis Fig.4 dargestellten Ausführungsbeispiel hat der Bevorratungsbehälter 1 die Form einer Flasche, die eine Sicherheitsflüssigkeitsaustrittsöffnung 2 und ein von derselben getrenntes Lufteintrittsrohr 3 aufweist. Die Sicherheitsflüssigkeitsaustrittsöffnung 2 und das Lufteintrittsrohr 3 münden in getrennte Bohrungen 4, 5 im Ventilgehäuse 6, das auf den Flaschenhals aufgeschraubt ist. In das Ventilgehäuse 6 ist eine Ventilhülse 7 eingesetzt, die an ihrem tankseitigen Ende gegenüber dem Ventilgehäuse 6 abgedichtet ist und an ihrem dem Bevorratungsbehälter 1 abgewandten Ende in ein Zerstäuberrad 8 mündet. In der Ventilhülse 7 ist verschiebbar ein Ventilkolben 9 angeordnet, der eine zentrale Bohrung 10 aufweist, in die ein die Bohrung 4 für Sicherheitsflüssigkeit im Ventilgehäuse 6 verlängerndes Sicherheitsflüssigkeitsrohr 11 ragt. Die Achse 12 des Zerstäuberrades 8 wird von einem Elektromotor 13 angetrieben. Um den Umfang des Zerstäuberrades 8 ist eine Prallfläche 14 vorgesehen, die gegenüber der Längsachse des Ventils geneigt ist. Weiters ist zur Sicherheitsflüssigkeitsfüllstandsüberwachung am Ventilgehäuse 6 ein Füllstandsüberwachungsrohr 32 dicht befestigt, das am oberen, dem Ventilgehäuse 6 abgewandten Ende, einen oberen und einen unteren Schwimmeranschlag 30, 31 aufweist. Im Inneren des Füllstandsüberwachungsrohrs 32 ist ein Reedkontakt 33 angebracht, der beim Absinken des koaxialen Schwimmers 28 mit dem Magnet 34 schaltet. In Fig.1 ist das Sicherheitsflüssigkeitsniveau 29 über der Sicherheitsflüssigkeitsfüllstandsüberwachungseinrichtung dargestellt, Fig.2 stellt einen entleerten Bevorratungsbehälter dar.Im in Fig.1 to Fig.4 illustrated embodiment, the storage container 1 has the shape of a bottle having a safety fluid outlet opening 2 and a separate from the same air inlet tube 3. The safety fluid outlet opening 2 and the air inlet pipe 3 open into separate holes 4, 5 in the valve housing 6, which is screwed onto the bottle neck. In the valve housing 6, a valve sleeve 7 is inserted, which is sealed at its tank-side end opposite the valve housing 6 and at its end facing away from the storage container 1 in a Zerstäuberrad 8 opens. In the valve sleeve 7, a valve piston 9 is slidably disposed, which has a central bore 10 into which a bore 4 for safety fluid in the valve housing 6 extending safety fluid tube 11 protrudes. The axis 12 of the atomizer wheel 8 is driven by an electric motor 13. Around the circumference of the atomizer 8, a baffle 14 is provided, which is inclined relative to the longitudinal axis of the valve. Furthermore, a level monitoring tube 32 is tightly attached to the safety fluid level monitoring on the valve housing 6, which has an upper and a lower float stop 30, 31 at the top, the valve housing 6 facing away from the end. Inside the level monitoring pipe 32, a reed contact 33 is mounted, which switches with the magnet 34 when the coaxial float 28 descends. In Fig.1 the safety fluid level 29 is shown above the safety fluid level monitoring device, Fig.2 represents a depleted storage container.

Im geöffneten Zustand des Ventils (siehe Fig.4) tritt die Sicherheitsflüssigkeit vom Bevorratungsbehälter 1 durch die Sicherheitsflüssigkeitsaustrittsöffnung 2 in die Bohrung 4 im Ventilgehäuse 6 und durch das Sicherheitsflüssigkeitsrohr 11 in die zentrale Bohrung 10 des Ventilkolbens 9. Von der zentralen Bohrung 10 gelangt es durch radiale Bohrungen 15 in den Raum 16 zwischen dem Ventilkolben 9 und der Ventilhülse 7, der im geöffneten Zustand des Ventils mit einem Innenraum des Zerstäuberrades 8 kommuniziert. Der beschriebene Weg der Sicherheitsflüssigkeit, der durch die Pfeillinie 26 in Fig.4 dargestellt ist, bildet den Flüssigkeitskanal des Ventils. Gleichzeitig tritt Luft durch eine Luftöffnung 17 im Ventilgehäuse 6 und einen Durchbruch 18 in der Ventilhülse 7 in einen Raum 19 zwischen der Ventilhülse 7 und dem Ventilkolben 9, welcher im geöffneten Zustand des Ventils mit der Bohrung 5 für Luft im Ventilgehäuse 6 und damit mit dem Lufteintrittsrohr 3 und dem Inneren des Bevorratungsbehälters 1 kommuniziert. Der beschriebene Weg der Luft, der durch die Pfeillinie 27 in Fig.4 dargestellt ist, bildet den Lufteintrittskanal. Der Flüssigkeitskanal und der Lufteinrittskanal sind durch den O-Ring 21 von einander getrennt, so dass im Einsatzfall die Sicherheitsflüssigkeit aus dem Bevorratungsbehälter entnommen werden kann und gleichzeitig der Bevorratungsbehälter belüftet werden kann, damit während des Ausbringens der Sicherheitsflüssigkeit die Sicherheitsflüssigkeitsmenge pro Zeiteinheit annähernd konstant gehalten werden kann.When the valve is open (see Figure 4 ) enters the safety liquid from the storage container 1 through the safety fluid outlet opening 2 in the bore 4 in the valve housing 6 and through the safety fluid tube 11 into the central bore 10 of the valve piston 9. From the central bore 10 it passes through radial holes 15 in the space 16 between the valve piston 9 and the valve sleeve 7, which communicates with an interior of the Zerstäuberrades 8 in the open state of the valve. The path of the safety fluid described by the arrow line 26 in Figure 4 is shown, forms the fluid channel of the valve. At the same time, air passes through an air opening 17 in the valve housing 6 and an opening 18 in the valve sleeve 7 in a space 19 between the valve sleeve 7 and the valve piston 9, which in the open state of the valve with the bore 5 for air in the valve housing 6 and thus with the Air inlet pipe 3 and the interior of the storage container 1 communicates. The described path of the air passing through the arrow line 27 in FIG Figure 4 is shown, forms the air inlet channel. The liquid channel and the Lufteinrittskanal are separated by the O-ring 21 from each other, so that in case of emergency, the safety liquid can be removed from the storage container and at the same time the storage container can be vented so that during the discharge of the safety liquid, the safety fluid quantity per unit time are kept approximately constant can.

Im geschlossenen Zustand des Ventils (siehe Fig.3) ist der Raum 16 zwischen dem Ventilkolben 9 und der Ventilhülse 7 durch die O-Ringe 20 und 21 geschlossen und kommuniziert nur mit den radialen Bohrungen 15, so dass keine Sicherheitsflüssigkeit aus dem Flüssigkeitskanal in den Innenraum des Zerstäuberrades 8 gelangen kann. Gleichzeitig ist der Raum 19 zwischen dem Ventilkolben 9 und der Ventilhülse 7 durch die O-Ringe 21 und 22 geschlossen und kommuniziert nur mit dem Durchbruch 18 in der Ventilhülse 7, so dass keine Luft durch den Lufteintrittskanal in das Lufteintrittsrohr 3 und damit in den Bevorratungsbehälter 1 gelangen kann. Die Position des Ventilkolbens 9 gegenüber der Ventilhülse 7 sichert einen dauerhaft dichten Verschluss des Bevorratungsbehälters 1.When the valve is closed (see Figure 3 ) is the space 16 between the valve piston 9 and the valve sleeve 7 closed by the O-rings 20 and 21 and communicates only with the radial bores 15, so that no safety liquid from the liquid channel can get into the interior of the Zerstäuberrades 8. At the same time the space 19 between the valve piston 9 and the valve sleeve 7 is closed by the O-rings 21 and 22 and communicates only with the opening 18 in the valve sleeve 7, so that no air through the air inlet channel into the air inlet pipe 3 and thus in the storage container 1 can get. The position of the valve piston 9 with respect to the valve sleeve 7 ensures a permanently sealed closure of the storage container 1.

Im dargestellten erfindungsgemäßen Ausbringgerät kann das als Schieberventil ausgebildete Ventil durch den Elektromotor 13 von seiner geschlossenen Position (Fig.3) in seine geöffnete Position (Fig.4) verschoben werden. Im Falle eines Brandes versetzt der Elektromotor 13, z.B. angesteuert von einer Steuereinheit, die von einer Branderkennungseinrichtung ein Signal erhalten hat, das Zerstäuberrad 8 in Rotation. Im Innenraum des Zerstäuberrades ist ein radialer Stift 23 vorgesehen, der als Auflaufelement für eine Auflauffläche 24 am Ventilkolben 9 dient. Die Auflauffläche 24 des Ventilkolbens 9 läuft bei der Drehung des Zerstäuberrades 8 am Stift 23 und der Ventilkolben 9 wird in Richtung des Bevorratungsbehälter 1 gegenüber der Ventilhülse 7 verschoben bis er sich in der geöffneten Position (Fig.4) befindet, in der die am Umfang des Ventilkolbens 9 liegenden O-Ringe 20 und 22 keinen Kontakt mehr mit der Ventilhülse 7 haben und in der daher der Flüssigkeitskanal 26 und der Lufteintrittstoffkanal 27 durchgängig sind. Die Sicherheitsflüssigkeit kann daher vom Raum 16 in den Innenraum des Zerstäuberrades 8 und von dort durch die Ausbringöffnungen 25 radial nach außen strömen. Die durch die Drehung des Zerstäubungsrades 8 erzeugte Zentrifugalkraft lässt einen Unterdruck entstehen und saugt Sicherheitsflüssigkeit aus dem Bevorratungsbehälter 1. Die aus den Ausbringöffnungen 25 austretende Sicherheitsflüssigkeit wird durch den Aufprall auf die Prallfläche 14 weiter zerstäubt. Gleichzeitig kann Luft durch den Lufteintrittskanal in den Bevorratungsbehälter 1 nachströmen.In the dispensing device according to the invention shown, the valve designed as a slide valve by the electric motor 13 from its closed position ( Figure 3 ) in its open position ( Figure 4 ) are moved. In the event of a fire, the electric motor 13, for example driven by a control unit, which has received a signal from a fire detection device, the atomizer 8 in rotation. In the interior of the Zerstäuberrades a radial pin 23 is provided, which serves as a run-up element for a ramp surface 24 on the valve piston 9. The ramp surface 24 of the valve piston 9 runs at the rotation of the Zerstäuberrades 8 on the pin 23 and the valve piston 9 is moved in the direction of the storage container 1 relative to the valve sleeve 7 until it is in the open position ( Figure 4 ) is in which the lying on the circumference of the valve piston 9 O-rings 20 and 22 have no contact with the valve sleeve 7 and in which therefore the liquid channel 26 and the air inlet material channel 27 are continuous. The safety fluid can therefore flow radially from the space 16 into the interior of the Zerstäuberrades 8 and from there through the Ausbringöffnungen 25 to the outside. The centrifugal force generated by the rotation of Zerstäubungsrades 8 creates a negative pressure and sucks safety fluid from the storage container 1. The emerging from the discharge openings 25 safety fluid is further atomized by the impact on the baffle 14. At the same time, air can flow in through the air inlet channel into the storage container 1.

Im in Fig.5 bis Fig.8 dargestellten Ausführungsbeispiel hat der Bevorratungsbehälter 35 die Form eines hohlen Quaders, der mittels Deckel 36 und O-Ring 37 abgedichtet ist. Die Sicherheitsflüssigkeitsfüllstandsüberwachung wird durch einen handelsüblichen Niveausensor 68 realisiert. In Fig.5 befindet dich das Sicherheitsflüssigkeitsniveau über dem Niveausensor 68, in Fig.6 unterhalb. Weiters weist der Bevorratungsbehälter eine Sicherheitsflüssigkeitsaustrittsöffnung 38 und ein von derselben getrenntes Lufteintrittsrohr 39 auf. Die Sicherheitsflüssigkeitsaustrittsöffnung 38 mündet in eine zentrale Bohrung 40 des Ventilkolbens 41, das Lufteintrittsrohr 39 mündet in einen Hohlraum 42 zwischen Ventilgehäuse 43 und einem Topf 44. Das Ventilgehäuse 43 ist mit dem Bevorratungsbehälter 35 dicht verschraubt, durch einen O-Ring 45 abgedichtet und mündet an dem dem Bevorratungsbehälter 35 abgewandten Ende in ein Zerstäuberrad 46. Im Ventilgehäuse 43 ist verschiebbar ein Ventilkolben 41 angeordnet, der eine zentrale Bohrung 40 aufweist, in die ein die Sicherheitsflüssigkeitsaustrittsöffnung 38 verlängerndes Sicherheitsflüssigkeitsrohr 47 ragt. Die Achse 48 des Zerstäuberrades 46 wird von einem Elektromotor 49 angetrieben. Um den Umfang des Zerstäuberrades 46 ist eine Prallfläche 50 vorgesehen, die gegenüber der Längsachse des Ventils geneigt ist.Im in Fig.5 to Fig.8 illustrated embodiment, the storage container 35 has the shape of a hollow cuboid, which is sealed by means of lid 36 and O-ring 37. The safety fluid level monitoring is realized by a commercially available level sensor 68. In Figure 5 is the safety fluid level above the level sensor 68, in Figure 6 below. Furthermore, the storage container has a safety fluid outlet opening 38 and an air inlet tube 39 separated from it. The safety fluid outlet opening 38 opens into a central bore 40 of the valve piston 41, the air inlet tube 39 opens into a cavity 42 between the valve housing 43 and a pot 44. The valve housing 43 is tightly screwed to the storage container 35, sealed by an O-ring 45 and opens the end facing away from the storage container 35 in a Zerstäuberrad 46. In the valve housing 43 is slidably a valve piston 41st arranged, which has a central bore 40, into which a safety liquid tube 47 extending the safety fluid outlet opening extends. The axis 48 of the Zerstäuberrades 46 is driven by an electric motor 49. Around the circumference of the atomizer wheel 46, a baffle 50 is provided, which is inclined with respect to the longitudinal axis of the valve.

In geöffneten Zustand des Ventils (siehe Fig.8) tritt die Sicherheitsflüssigkeit vom Bevorratungsbehälter 35 durch die Sicherheitsflüssigkeitsaustrittsöffnung 38 und durch das Sicherheitsflüssigkeitsrohr 47 in die zentrale Bohrung 40 des Ventilkolbens 41. Von der zentralen Bohrung 40 gelangt es durch radiale Bohrungen 51 in den Raum 52 zwischen dem Ventilkolben 41 und dem Ventilgehäuse 43, der im geöffneten Zustand des Ventils mit dem Innenraum 53 des Zerstäuberrades 46 kommuniziert. Der beschriebene Weg der Sicherheitsflüssigkeit, der durch die Pfeillinie 54 in Fig.8 dargestellt ist, bildet den Flüssigkeitskanal des Ventils. Gleichzeitig tritt Luft durch eine Luftöffnung 55 im Ventilgehäuse 43 in einen Raum 56 zwischen dem Ventilgehäuse 43 und dem Ventilkolben 41, welcher im geöffneten Zustand des Ventils mit einem Hohlraum 42 zwischen Ventilgehäuse 43 und dem Topf 44 und der Lufteintrittsbohrung 57 und damit mit dem Lufteintrittsrohr 39 und dem Inneren des Bevorratungsbehälters 35 kommuniziert. Der beschriebene Weg der Luft, der durch die Pfeillinie 58 in Fig.8 dargestellt ist, bildet den Lufteintrittskanal. Der Flüssigkeitskanal und der Lufteinrittskanal sind durch den O-Ring 69 von einander getrennt, so dass im Einsatzfall die Sicherheitsflüssigkeit aus dem Bevorratungsbehälter entnommen werden kann und gleichzeitig der Bevorratungsbehälter belüftet werden kann, damit während des Ausbringens der Sicherheitsflüssigkeit die Sicherheitsflüssigkeitsmenge pro Zeiteinheit annähernd konstant gehalten werden kann.In the open state of the valve (see Figure 8 ) enters the safety liquid from the storage tank 35 through the Sicherheitsflüssigkeitsaustrittsöffnung 38 and through the Sicherheitsflüssigkeitsrohr 47 in the central bore 40 of the valve piston 41. From the central bore 40 it passes through radial holes 51 in the space 52 between the valve piston 41 and the valve housing 43, the in the opened state of the valve with the interior 53 of the Zerstäuberrades 46 communicates. The described path of the safety fluid, which is indicated by the arrow line 54 in FIG Figure 8 is shown, forms the fluid channel of the valve. At the same time air passes through an air opening 55 in the valve housing 43 in a space 56 between the valve housing 43 and the valve piston 41, which in the open state of the valve with a cavity 42 between the valve housing 43 and the pot 44 and the air inlet bore 57 and thus with the air inlet pipe 39 and the interior of the storage container 35 communicates. The described path of the air passing through the arrow 58 in FIG Figure 8 is shown, forms the air inlet channel. The liquid channel and the air inlet channel are separated from each other by the O-ring 69, so that in the case of application, the safety liquid can be removed from the storage container and at the same time the storage container can be vented so that the quantity of safety fluid per unit of time is kept approximately constant during the discharge of the safety fluid can.

Im geschlossenen Zustand des Ventils (siehe Fig.7) ist der Raum 52 zwischen dem Ventilkolben 41 und dem Ventilgehäuse 43 durch die O-Ringe 69 und 59 geschlossen und kommuniziert nur mit den radialen Bohrungen 51, so dass keine Sicherheitsflüssigkeit aus dem Flüssigkeitskanal Fig.8 in den Innenraum 53 des Zerstäuberrades 46 gelangen kann. Gleichzeitig ist der Raum 56 zwischen dem Ventilkolben 41 und dem Ventilgehäuse 43 durch die O-Ringe 69 und 60 geschlossen und kommuniziert nur mit den Luftöffnungen 55 im Ventilgehäuse 43, so dass keine Luft durch den Lufteintrittskanal Fig.8 in das Lufteintrittsrohr 39 und damit in den Bevorratungsbehälter 35 gelangen kann. Die Position des Ventilkolbens 41 gegenüber dem Ventilgehäuses 43 sichert einen dauerhaft dichten Verschluss des Bevorratungsbehälters 35.When the valve is closed (see Figure 7 ), the space 52 between the valve piston 41 and the valve housing 43 is closed by the O-rings 69 and 59 and communicates only with the radial bores 51, so that no safety fluid from the fluid channel Figure 8 can get into the interior 53 of the Zerstäuberrades 46. At the same time, the space 56 between the valve piston 41 and the valve housing 43 is closed by the O-rings 69 and 60 and only communicates with the air openings 55 in the valve housing 43, so that no air through the air inlet channel Figure 8 in the air inlet pipe 39 and thus can get into the storage container 35. The position of the valve piston 41 with respect to the valve housing 43 ensures a permanently sealed closure of the storage container 35.

In dem dargestellten erfindungsgemäßen Ausbringgerät kann der Ventilkolben 41 in dem als Schieberventil ausgebildete Ventil durch den Elektromotor 49 von seiner geschlossenen Position (Fig.5 und Fig.7) in seine geöffnete Position (Fig. 6 und Fig.8) verschoben werden. In Ruheposition (Fig.7) ist der Ventilkolben 41 durch eine Feder 61 vorgespannt, die sich einerseits am Ventilgehäuse 43 abstützt und andererseits den Ventilkolben 41 über dessen Klauen 62 auf die dazu überlappend orientierten Klauen 63 des Zerstäuberrades 46 presst. Im Einsatzfall versetzt der Elektromotor 49, z.B. angesteuert von einer Steuereinheit, das Zerstäuberrad 46 in Rotation. Sobald sich die Klauen 62 des Ventilkolbens 41 nicht mehr an den Klauen 63 des Zersäuberrades 46 abstützen, wird der Ventilkolbens 41 durch die Feder 61 in Richtung des Elektromotors 49 gegenüber dem Ventilgehäuse 43 verschoben bis dessen Schulter 64 an der Haltefläche 65 der Stützscheibe 66 anliegt und sich somit in geöffneter Position befindet (Fig.8), in der die am Umfang des Ventilkolbens 41 liegenden O-Ringe 59 und 60 keinen Kontakt mehr mit dem Ventilgehäuse 43 haben und in der daher der Flüssigkeitskanal und der Lufteintrittskanal durchgängig sind. Die Sicherheitsflüssigkeit kann daher vom Raum 52 in den Innenraum des Zerstäuberrades 46 und von dort durch die Ausbringöffnungen 67 radial nach außen strömen. Die durch die Drehung des Zerstäubungsrades 46 erzeugte Zentrifugalkraft lässt einen Unterdruck entstehen und saugt Sicherheitsflüssigkeit aus dem Bevorratungsbehälter 35. Die aus den Ausbringöffnungen 67 austretende Sicherheitsflüssigkeit wird durch den Aufprall auf die Prallfläche 50 weiter zerstäubt. Gleichzeitig kann Luft durch den Lufteintrittskanal in den Bevorratungsbehälter 35 nachströmen.In the illustrated dispensing device according to the invention, the valve piston 41 in the valve designed as a slide valve by the electric motor 49 from its closed position ( Figure 5 and Figure 7 ) in its open position ( Fig. 6 and Figure 8 ) are moved. In rest position ( Figure 7 ), the valve piston 41 is biased by a spring 61, which is supported on the one hand on the valve housing 43 and on the other hand, the valve piston 41 presses on the claw 62 on the overlapping oriented claws 63 of the atomizer wheel 46. In use, the electric motor 49, for example driven by a control unit, the atomizer 46 in rotation. Once the jaws 62 of the valve piston 41 are no longer supported on the claws 63 of the Zersäuberrades 46, the valve piston 41 is displaced by the spring 61 in the direction of the electric motor 49 relative to the valve housing 43 until the shoulder 64 abuts the support surface 65 of the support plate 66 and is thus in the open position ( Figure 8 ), in which lying on the circumference of the valve piston 41 O-rings 59 and 60 have no contact with the valve housing 43 and in which therefore the liquid passage and the air inlet passage are continuous. The safety fluid can therefore flow radially from the space 52 into the interior of the Zerstäuberrades 46 and from there through the Ausbringöffnungen 67 to the outside. The centrifugal force generated by the rotation of the Zerstäubungsrades 46 creates a negative pressure and sucks safety fluid from the storage container 35. The emerging from the discharge openings 67 safety fluid is further atomized by the impact on the baffle 50. At the same time, air can flow in through the air inlet channel into the storage container 35.
