Description

Die Erfindung betrifft ein Beimischgerät zur Abgabe von löslichen Zusatzstoffen an strömende Flüssigkeiten, mit einem Flüssigkeitseinlaß in das und einem Flüssigkeitsauslaß aus dem Gerät, einem Aufnahmebehälter für den Zusatzstoff sowie einem Ventil zur wahlweisen Abgabe von zusatzfreier und mit Zusatzstoff versehener Flüssigkeit, dessen drehbarer Ventilkörper einen Verschlußabschnitt zum Verschließen einer Ventileinlaßöffnung aufweist und eine Flüssigkeitsführung zur direkten Verbindung der Ventileinlaßöff nung mit dem Flüssigkeitsauslaß sowie eine zweite Flüssigkeitsführung zur Verbindung der Ventileinlaßöffnung mit dem Aufnahmebehälter steuert.The invention relates to an admixing device for dispensing soluble additives to flowing liquids, with a liquid inlet into and a liquid outlet from the device, a receptacle for the additive and a valve for the optional dispensing of additive-free and additive-containing liquid, the rotatable valve body of which has a closure section for closing a valve inlet opening and controls a liquid guide for the direct connection of the valve inlet opening to the liquid outlet and a second liquid guide for connecting the valve inlet opening to the receptacle.

Ein derartiges Beimischgerät ist aus DE-A-32 30 783 bekannt. Bei diesem bekannten Beimischgerät muß der drehbare Ventilkörper sowohl eine Ventileinlaßöffnung in einer Zylinderfläche als auch einer Einlaßöffnung in den Aufnahmebehälter, die in der Stirnwand des Zylinders angeordnet ist, dichtend abdecken können. Der Ventilkörper besitzt also zwei Dichtflächen. Der Ventilkörper muß von oben in das Ventilgehäuse eingesetzt werden, woran anschließend ein Deckel aufgesetzt und ein Drehknopf angebracht werden muß.Such an admixing device is known from DE-A-32 30 783. In this known mixing device, the rotatable valve body must be able to cover both a valve inlet opening in a cylinder surface and an inlet opening in the receptacle, which is arranged in the end wall of the cylinder. The valve body thus has two sealing surfaces. The valve body must be inserted into the valve housing from above, after which a cover must be placed and a rotary knob attached.

Ebenfalls bekannt ist eine Waschbürste mit einem Ventil, mit dessen Hilfe sowohl reines Wasser als auch mit flüssigem Waschmittel versehenes Wasser in die Waschbürste geleitet werden kann (DE-A-20 38 625). Das Ventil ist wiederum ein Drehventil, wobei ebenfalls sowohl in der zylindrischen Wand des Ventilgehäuses als auch in der Stirnseite des Ventilgehäuses je eine Öffnung vorhanden ist, die von dem Ventilkörper abgedichtet sein muß. Der Aufnahmebehälter für den Zusatzstoff befindet sich seitlich neben dem drehbaren Ventilkörper.Also known is a washing brush with a valve, with the aid of which both pure water and water provided with liquid detergent can be passed into the washing brush (DE-A-20 38 625). The valve is in turn a rotary valve, and there is also an opening in both the cylindrical wall of the valve housing and in the end face of the valve housing, which opening must be sealed by the valve body. The receptacle for the additive is located on the side next to the rotatable valve body.

Ein ähnliches Gerät ist aus US-A-16 77 645 bekannt. Hier ist ein drehbares Ventil vorgesehen, das zwei getrennte Durchlässe aufweist und gegenüber insgesamt vier Bohrungen abgedichtet sein muß.A similar device is known from US-A-16 77 645. Here a rotatable valve is provided, which has two separate passages and must be sealed against a total of four bores.

Der Erfindung liegt die Aufgabe zugrunde, ein Beimischgerät zur Abgabe von löslichen Zusatzstoffen an eine strömende Flüssigkeit zu schaffen, das bei möglichst einfachem und unkompliziertem Aufbau dennoch sicher arbeitet und eine gute Ventilsteuermöglichkeit vorsieht.The invention has for its object to provide an admixer for dispensing soluble additives to a flowing liquid, which still works safely with a simple and uncomplicated structure and provides a good valve control option.

Zur Lösung dieser Aufgabe ist erfindungsgemäß vorgesehen, daß die Flüssigkeitsführung zu dem Aufnahmebehälter für den Zusatzstoff als geschlossener, im Inneren des Ventilkörpers angeordneter Kanal ausgebildet ist, der in der Umfangsfläche des Ventilkörpers beginnt und in dem Aufnahmebehälter ausmündet.To achieve this object it is provided according to the invention that the liquid guide to the receptacle for the additive is designed as a closed channel arranged inside the valve body, which begins in the peripheral surface of the valve body and opens into the receptacle.

Durch diese Ausgestaltung braucht der Ventilkörper nur noch eine Öffnung aufzuweisen, die von dem Ventilkörper abgedichtet werden kann, nämlich die Einlaßöffnung. Die Auslaßöffnung für das reine Wasser braucht ebenso wenig abgedichtet zu sein wie die Ausmündeöffnung des Zusatzkanals in dem Aufnahmebehälter für den Zusatzstoff.With this configuration, the valve body need only have one opening that can be sealed by the valve body, namely the inlet opening. The outlet opening for the pure water need not be sealed any more than the outlet opening of the additional channel in the receptacle for the additive.

In Weiterbildung kann vorgesehen sein, daß der Flüssigkeitsauslaß aus dem Aufnahmebehälter stromab des Ventils in den Flüssigkeitsauslaß des Beimischgerätes mündet. Dadurch wird sichergestellt, daß kein Rückströmen des reinen Wassers in den Aufnahmebehälter auftreten kann, so daß das Ventil aus diesem Grunde sehr einfach aufgebaut ist.In a further development it can be provided that the liquid outlet from the receptacle opens into the liquid outlet of the admixing device downstream of the valve. This ensures that no backflow of pure water can occur in the receptacle, so that the valve is very simple for this reason.

Die Erfindung schlägt vor, daß das Ventil ein kreiszylindrisches Ventilgehäuse aufweist, in dem die Ventileinlaßöffnung angeordnet ist, und der zylindrische Ventilkörper mindestens eine mit der Ventileinlaßöffnung zusammenwirkende Steuerkante aufweist. Dabei kann mit Vorteil der Ventilkörper quer zur Richtung des Flüssigkeitsverlaufs angeordnet und der Aufnahmebehälter in Verlängerung der Drehachse des Ventilkörpers angeordnet sein. Dies ergibt einen außerordentlich einfachen Aufbau, da der Flüssigkeitskanal für den Zusatzstoff als in der Drehachse liegende Bohrung ausgebildet werden kann, die von einer Radialbohrung getroffen wird.The invention proposes that the valve has a circular cylindrical valve housing, in which the valve inlet opening is arranged, and the cylindrical valve body has at least one control edge cooperating with the valve inlet opening. The valve body can advantageously be arranged transversely to the direction of the liquid flow and the receptacle can be arranged in an extension of the axis of rotation of the valve body. This results in an extremely simple construction, since the liquid channel for the additive can be designed as a bore lying in the axis of rotation, which is hit by a radial bore.

Die Erfindung schlägt weiterhin vor, daß der Ventilkörper einstückig mit einem Drehknopf ausgebildet und in das Ventilgehäuse einschnappbar ist. Aufgrund der kreiszylindrischen Ausbildung des Inneren des Ventilgehäuses läßt sich damit der Ventilkörper einfach einschnappen, wobei er mit einer Schulter an der Unterseite des Ventilgehäuses angreifen kann.The invention further proposes that the valve body is formed in one piece with a rotary knob and can be snapped into the valve housing. Due to the circular cylindrical design of the interior of the valve housing, the valve body can be easily snapped in, and it can engage with a shoulder on the underside of the valve housing.

Zur Abdichtung kann vorgesehen sein, daß der Ventilkörper einen in eine Nut eingesetzten 0-Ring aufweist, der im Bereich des Verschlußabschnitts unterhalb der Ventileinlaßöffnung und im übrigen Bereich oberhalb der Ventileinlaßöffnung liegt bzw. umgekehrt. Damit läßt sich mit Hilfe eines einfachen Elementes, nämlich eines O-Ringes, eine einfache Abdichtung sowohl des Verschlußabschnittes als auch des Kanals für das reine Wasser und des Kanals für das mit Zusatzstoff versehene Wasser durchführen.For sealing purposes it can be provided that the valve body has an O-ring inserted into a groove, which lies in the area of the closure section below the valve inlet opening and in the remaining area above the valve inlet opening or vice versa. This can be done with the help of a simple element, namely an O-ring, a simple seal both the closure portion and the channel for the pure water and the channel for the water provided with additive.

Die Erfindung schlägt weiterhin vor, daß der in den Aufnahmebehälter für den Zusatzstoff führende Kanal in diesen rohrartig verlängert ist. Dadurch wird es möglich, im Zusatzbehälter eine ringförmige Tablette als Zusatzstoff zu verwenden, bei der aufgrund der rohrartigen Verlängerung das Wasser zur einen Stirnseite geführt werden kann, so daß es sowohl längs der äußeren als auch längs der innneren Oberfläche abfließen kann. Durch diese Art der Ausbildung des Zusatzstoffes wird ermöglicht, daß trotz der sich abnutzenden Tablette die Oberfläche im wesentlichen konstant bleibt.The invention further proposes that the channel leading into the receptacle for the additive is extended in a tube-like manner. This makes it possible to use an annular tablet as an additive in the additional container, in which, due to the tubular extension, the water can be guided to one end face, so that it can flow off both along the outer surface and along the inner surface. This type of formation of the additive enables the surface to remain essentially constant despite the tablet being worn.

In Weiterbildung kann vorgesehen sein, daß der Aufnahmebehälter einen Ringraum, vorzugsweise radial außerhalb des Ventilgehäuses aufweist, aus dem die Flüssigkeit herausgeführt ist. Dies führt zu einem gleichmäßigen Abtrag des Zusatzstoffes.In a further development it can be provided that the receptacle has an annular space, preferably radially outside the valve housing, from which the liquid is led out. This leads to an even removal of the additive.

Es kann vorgesehen sein, daß die rohrartige Verlängerung des Kanals bis in den Bereich der gegenüberliegenden Behälterwand reicht. In diesem Bereich kann die Behälterwand vorzugsweise eine Verwirbelungseinrichtung aufweisen, die ebenfalls dafür sorgt, daß der Abtrag des Zusatzstoffes möglichst gleichmäßig erfolgt.It can be provided that the tubular extension of the channel extends into the area of the opposite container wall. In the In this area, the container wall can preferably have a swirling device, which also ensures that the removal of the additive takes place as evenly as possible.

Die Erfindung schlägt vor, daß das Beimischgerät einen Handgriff aufweisen kann, so daß es von dem Bediener in der Hand gehalten werden kann. Aufgrund der von der Erfindung vorgeschlagenen Maßnahmen läßt sich das Beimischgerät so klein und leicht ausbilden, daß es als tragbares Gerät kleiner als der Handgriff sein kann.The invention proposes that the admixing device can have a handle so that it can be held in the hand of the operator. Due to the measures proposed by the invention, the admixing device can be so small and light that it can be smaller than the handle as a portable device.

Damit das Beimischgerät in Zusammenhang mit einer Waschbürste, einer Spritzpistole oder ähnlichen Zusatzgeräten verwendet werden kann, sieht die Erfindung vor, daß es einen Kupplungsnippel zur Verbindung mit einem weiteren Gerät aufweist.So that the admixing device can be used in connection with a washing brush, a spray gun or similar additional devices, the invention provides that it has a coupling nipple for connection to another device.

Um den Aufnahmebehälter für den Zusatzstoff im Nebenstrom durchströmen zu können, kann erfindungsgemäß vorgesehen sein, daß die Öffnung des Zusatzkanals in der Umfangsfläche des Ventilkörpers einen kleineren Querschnitt als die Ventileinsatzöffnung aufweist und rohrartig ausgebildet ist. Dadurch kann ein Teil des einströmenden Wassers seitlich an dem Rohr vorbeiströmen und direkt zum Auslaß des Gerätes gelangen.In order to be able to flow through the receptacle for the additive in the secondary flow, it can be provided according to the invention that the opening of the additional channel in the peripheral surface of the valve body has a smaller cross section than the valve insert opening and is tubular. This allows part of the inflowing water to flow past the side of the pipe and directly to the outlet of the device.

In das Gewinde 12 des Ansatzes 13 ist unter Zwischenlage eines Dichtungsringes 14 ein Anschlußnippel 15 eingeschraubt, der zum Anschluß an einen Schlauch ausgebildet ist.The admixing device shown in FIG. 1 contains a housing 11 made of plastic, which has on its left side in FIG. 1 an attachment 13 provided with a thread 12. Through the hollow extension 13, the water can flow into the device to the valve arranged in the middle. In the thread 12 of the projection 13, a connecting nipple 15 is screwed in with the interposition of a sealing ring 14, which is designed for connection to a hose.

Innerhalb des Gerätegehäuses 11 ist ein Ventilgehäuse 16 angeordnet, das etwa die Form eines Kreiszylinderringes aufweist. An seiner dem Ansatz 13 zugewandten Seite weist das Ventilgehäuse eine Ventileinlaßöffnung 17 auf, die sich in Richtung auf den Ansatz 13 trichterförmig erweitert.A valve housing 16, which has approximately the shape of a circular cylinder ring, is arranged within the device housing 11. On its side facing the extension 13, the valve housing has a valve inlet opening 17 which widens in a funnel shape in the direction of the extension 13.

An dem Ventilgehäuse 16 ist auf der dem Einlaß entgegengesetzten Seite ein Rohrstutzen 18 angebracht, dessen Inneres über eine Öffnung 19, siehe Fig. 3, mit dem Inneren des Ventilgehäuses 16 in Verbindung steht. Der Rohrstutzen 18 erstreckt sich bis in den Flüssigkeitsauslaß des Beimischgerätes.On the valve housing 16 on the side opposite the inlet, a pipe socket 18 is attached, the interior of which is connected to the interior of the valve housing 16 via an opening 19, see FIG. 3. The pipe socket 18 extends into the liquid outlet of the admixer.

Das Ventilgehäuse 16weist an seiner Unterseite einen nach innen vorspringenden Rand 20 auf, der eine leichte Durchmesserverringerung des Ventilgehäuses 16 bildet. In dem Ventilgehäuse eingesetzt ist ein einstückiger Ventilkörper 21, der um die Längsachse des zylindrischen Ventilgehäuses 16 drehbar ist. Der Ventilkörper weist in seinem oberen Randbereich und in seinem unteren Bereich je eine Ringnut 22, 23 auf, in der je ein 0-Ring 24 angeordnet ist. Die beiden O-Ringe 24 liegen an der glatten Innenwand des Ventilgehäuses 16 an und dienen zum Abdichten des Ventilkörpers.The valve housing 16 has on its underside an inwardly projecting edge 20 which forms a slight reduction in the diameter of the valve housing 16. Inserted in the valve housing is a one-piece valve body 21 which can be rotated about the longitudinal axis of the cylindrical valve housing 16. The valve body has an annular groove 22, 23 in its upper edge area and in its lower area, in each of which an O-ring 24 is arranged. The two O-rings 24 rest on the smooth inner wall of the valve housing 16 and serve to seal the valve body.

Der Ventilkörper wird zentral von einem in Richtung auf einen Aufnahmebehälter 29 offenen Rohr 25 durchsetzt, das konzentrisch zur Drehachse des Ventilkörpers 21 verläuft. Von der Außenseite des Ventilkörpers 21 her ist ein ebenfalls rohrförmiger Ansatz 26 angebracht, der etwa radial verläuft und in das Rohr 25 übergeht. Der rohrartige Ansatz 26 bildet eine Öffnung 27, die durch Verdrehen des Ventilkörpers 21 in Übereinstimmung mit der Ventileinlaßöffnung 17 gebracht werden kann. An seiner unteren Seite weist der Ventilkörper 21 eine rohrartige Verlängerung 28 auf, die in Verlängerung des Rohres 25 angeordnet ist. Das in die Öffnung 27 einströmende Wasser gelangt durch den rohrartigen Ansatz 26, das Rohr 25 und die Verlängerung 28 nach unten in einen Behälter 29 zur Aufnahme des Zusatzstoffes. Das Gerätegehäuse 11 besitzt in diesem Bereich ein Innengewinde 30, in das der Behälterdeckel 31 eingeschraubt ist, wobei eine Dichtung 32 für eine flüssigkeitsdichte Abdichtung sorgt. Die flache Mittelwand 33 des Behälterdekkels 31 weist eine aus vier senkrecht zueinander verlaufenden Flügeln 34 bestehende Verwirbelungseinrichtung auf, die in Verlängerung des Rohres 25 angeordnet ist. Das aus der Verlängerung 28 austretende Wasser wird dadurch durch die Flügel 34 verwirbelt.The valve body is penetrated centrally by a tube 25 which is open in the direction of a receiving container 29 and runs concentrically to the axis of rotation of the valve body 21. A likewise tubular extension 26 is attached from the outside of the valve body 21, which extends approximately radially and merges into the tube 25. The tubular extension 26 forms an opening 27 which can be brought into alignment with the valve inlet opening 17 by rotating the valve body 21. On its lower side, the valve body 21 has a tubular extension 28, which is arranged in the extension of the tube 25. The water flowing into the opening 27 passes through the tubular extension 26, the tube 25 and the extension 28 down into a container 29 for receiving the additive. The device housing 11 has in this area an internal thread 30 into which the container lid 31 is screwed, a seal 32 ensuring a liquid-tight seal. The flat middle wall 33 of the container lid 31 has a swirling device consisting of four mutually perpendicular wings 34, which is arranged in the extension of the tube 25. The water emerging from the extension 28 is thereby swirled by the wings 34.

Außerhalb des unteren Randes 20 des Ventilgehäuses 16 ist ein Ringraum 35 angeordnet, aus dem das Wasser durch eine in Fig. 3 zu sehende Öffnung 36 zum Flüssigkeitsauslaß des Beimischgerätes gelangen kann.An annular space 35 is arranged outside the lower edge 20 of the valve housing 16, from which the water can pass through an opening 36 shown in FIG. 3 to the liquid outlet of the admixing device.

Auf der der Verlängerung 28 gegenüberliegenden Seite enthält der Ventilkörper 21 einen Drehknopf 37 mit einer Platte 38, die das Ventilgehäuse nach oben abschließt. An der Unterseite der Platte 38 ist im Bereich der Spitze 39 des Drehknopfes 37 ein Ansatz 40 angebracht, der zusammen mit einem Gehäuseelement zur Begrenzung der Drehbewegung des Drehknopfes 37 dienen kann.On the side opposite the extension 28, the valve body 21 contains a rotary knob 37 with a plate 38 which closes off the valve housing at the top. On the underside of the plate 38, in the area of the tip 39 of the rotary knob 37, an attachment 40 is attached, which together with a housing element can serve to limit the rotary movement of the rotary knob 37.

Aus Fig. 2 geht die Form des Ventilkörpers 21 nochmals besonders deutlich hervor. Unterhalb der Platte 38 ist die erste Ringnut 22 mit der darin angeordneten Dichtung 24 vorhanden. Unterhalb der Dichtung 24 ist ein in Fig. 2 zu sehender Verschlußabschnitt 41 angeordnet, der von einer etwa V-förmig verlaufenden Nut 42 begrenzt wird. Rechts von dem Verschlußabschnitt 41 ist eine senkrechte Wand 43 zu sehen, in der das Rohr 26 mit seiner Öffnung 27 enthalten ist. Links von dem Verschlußabschnitt 41 ist kein Material vorhanden, so daß hier das Wasser vollständig frei durchfließen kann. In die Nut 42 wird ein O-Ring eingelegt, der der Nut 42 folgt. Auf der in Fig. 2 nicht zu sehenden anderen Seite des Ventilkörpers 21 verläuft die Nut direkt unterhalb der Nut 22 und parallel zu dieser, so daß der O-Ring dort im wesentlichen parallel zu dem O-Ring 24 verläuft.2 shows the shape of the valve body 21 again particularly clearly. Below the plate 38 there is the first annular groove 22 with the seal 24 arranged therein. Below the seal 24, a closure section 41 can be seen in FIG. 2, which is delimited by an approximately V-shaped groove 42. To the right of the closure section 41, a vertical wall 43 can be seen, in which the tube 26 with its opening 27 is contained. There is no material to the left of the closure section 41, so that the water can flow freely through here. An O-ring is inserted into the groove 42, which follows the groove 42. On the other side of the valve body 21, which cannot be seen in FIG. 2, the groove runs directly below the groove 22 and parallel to it, so that the O-ring there runs essentially parallel to the O-ring 24.

Unterhalb der Ringnut 23 besitzt der Ventilkörper 21 eine nach außen ragende Rippe 44 mit einer sich daran anschließenden abgeschrägten Schulter 45. Die Oberkante der Rippe 44 verläuft etwa senkrecht zur Längsachse des Ventilkörpers 21, so daß die Rippe 44 sich unter dem unteren Rand des Ventilgehäuses 16 festlegen kann. Das Einsetzen des Ventilkörpers wird durch die schräge Schulter 45 erleichtert.Below the annular groove 23, the valve body 21 has an outwardly projecting rib 44 with an adjoining beveled shoulder 45. The upper edge of the rib 44 runs approximately perpendicular to the longitudinal axis of the valve body 21, so that the rib 44 is located below the lower edge of the valve housing 16 can set. The inclined shoulder 45 facilitates the insertion of the valve body.

In Verschlußstellung ist der Verschlußabschnitt 41 derart angeordnet, daß er die Ventileinlaßöffnung 17 verschließt.In the closed position, the closing section 41 is arranged such that it closes the valve inlet opening 17.

Wird der Ventilkörper 21 derart verdreht, daß der Verschlußabschnitt 41 in Fig. 2 nach rechts gelangt, so kann das durch die Einlaßöffnung 17 strömende Wasser an der linken Seite der in der Nut 42 enthaltenen Dichtung vorbeifließen und durch die in Fig. 3 sichtbare Öffnung 19 aus dem Ventilgehäuse herausfließen, wobei die Öffnung 19 im Ventilgehäuse nicht abgedichtet zu sein braucht.If the valve body 21 is rotated such that the closure section 41 reaches the right in FIG. 2, the water flowing through the inlet opening 17 can flow past the left-hand side of the seal contained in the groove 42 and through the opening 19 visible in FIG. 3 flow out of the valve housing, the opening 19 in the valve housing need not be sealed.

Wird dagegen der Verschlußkörper in umgekehrter Richtung gedreht, so gelangt die Öffnung 27 des Rohres 26 nach und nach in Übereinstimmung mit der Ventileinlaßöffnung 17, so daß das Wasser durch die Öffnung 17 und 27, das Rohr 25 und die Verlängerung 28 in den Behälter 29 für den Zusatzstoff gelangt. Von dort aus gelangt das Wasser mit dem gelösten Zusatzstoff über den Ringraum 35 und die Öffnung in den äußeren Stutzen 46, der den Flüssigkeitsauslaß des Beimischgerätes bildet.Conversely, if the closure body is rotated in the opposite direction, the opening 27 of the tube 26 gradually comes into correspondence with the valve inlet opening 17, so that the water through the openings 17 and 27, the tube 25 and the extension 28 into the container 29 for gets the additive. From there, the water with the dissolved additive passes through the annular space 35 and the opening into the outer nozzle 46, which forms the liquid outlet of the admixer.

Fig. 3 zeigt im Schnitt das kreiszylinderförmige Ventilgehäuse 16 ohne den Ventilkörper. In der Innenwand des Ventilgehäuses 16 ist die Ventileinlaßöffnung 17 und die Auslaßöffnung 19 angeordnet. Die Auslaßöffnung 19 setzt sich in einem Rohrstutzen 18 fort, der in den Stutzen 46 führt. Das Ventilgehäuse 16 ist von einer ebenfalls etwa kreiszylinderförmigen Wand 47 umgeben, wobei eine etwa trichterförmige Leitung 48 die Flüssigkeitsverbindung zwischen dem Ansatz 13 und der Öffnung 17 herstellt. Die Flüssigkeit, die durch das Ventil in den Behälter 29 für den Zusatzstoff gelangt, kann von dort aus durch den Ringraum 35 und die Öffnung 36 ebenfalls in den Auslaßstutzen 46 gelangen.Fig. 3 shows in section the circular cylindrical valve housing 16 without the valve body. In the inner wall of the valve housing 16, the valve inlet opening 17 and the outlet opening 19 are arranged. The outlet opening 19 continues in a pipe socket 18 which leads into the socket 46. The valve housing 16 is surrounded by a likewise approximately circular-cylindrical wall 47, an approximately funnel-shaped line 48 establishing the fluid connection between the attachment 13 and the opening 17. The liquid that passes through the valve into the container 29 for the additive can also pass from there through the annular space 35 and the opening 36 into the outlet connection 46.

Fig. 4 bis 6 zeigen nun Schnitte durch das Ventilgehäuse 16 mit eingesetztem Ventilkörper. In Fig. 4 ist der Ventilkörper im Gegenuhrzeigersinn so weit gedreht, bis der Verschlußabschnitt 41 vollständig an der Ventileinlaßöffnung 17 vorbeigelangt ist. Das Wasser kann aus der Öffnung 17 durch den freien Raum des Ventilkörpers 21 unmittelbar in die Auslaßöffnung 19 gelangen. Die Öffnung 27 des rohrartigen Ansatzes 26 ist geschlossen.4 to 6 show sections through the valve housing 16 with the valve body inserted. In Fig. 4 the valve body is rotated counterclockwise until the closure portion 41 has completely passed the valve inlet opening 17. The water can pass directly from the opening 17 through the free space of the valve body 21 into the outlet opening 19. The opening 27 of the tubular extension 26 is closed.

Wird nun der Ventilkörper im Uhrzeigersinn gedreht, so wird die Ventileinlaßöffnung langsam geschlossen, bis die in Fig. 5 dargestellte Stellung erreicht ist, in der die Ventileinlaßöffnung 17 vollständig durch den Verschlußabschnitt 41 verschlossen ist. Das Beimischgerät ist gesperrt.If the valve body is now rotated clockwise, the valve inlet opening is slowly closed until the position shown in FIG. 5 is reached, in which the valve inlet opening 17 is completely closed by the closure section 41. The admixer is blocked.

Bei Weiterdrehung im Uhrzeigersinn gelangt die Öffnung 27 des Ansatzes 26 nach und nach in den Bereich der Ventileinlaßöffnung 17, bis die in Fig. 6 dargestellte Stellung erreicht ist, in der die gesamte Öffnung 27 innerhalb der Ventileinlaßöffnung 17 liegt. Das Wasser strömt im wesentlichen durch den Ansatz 26, das Rohr 25 und die Verlängerung 28 in den Aufnahmebehälter 29 für den Zusatzstoff.As the clockwise rotation continues, the opening 27 of the extension 26 gradually reaches the area of the valve inlet opening 17 until the position shown in FIG. 6 is reached, in which the entire opening 27 lies within the valve inlet opening 17. The water essentially flows through the neck 26, the pipe 25 and the extension 28 into the receptacle 29 for the additive.

Wie in Fig. 1 gestrichelt dargestellt ist, besitzt der Zusatzstoff die Form einer zylindrischen Tablette 53 mit einer Längsbohrung, die etwas größer ist als der Durchmesser der Verlängerung 28. Die Flüssigkeit strömt sowohl an der Innenseite als auch an der Außenseite des Zylinderringes vorbei, so daß bei einem Abtrag des Zusatzstoffes sich die Oberfläche im wesentlichen nicht verändert.As shown in dashed lines in Fig. 1, the additive has the shape of a cylindrical tablet 53 with a longitudinal bore which is slightly larger than the diameter of the extension 28. The liquid flows past both the inside and the outside of the cylinder ring, so that the surface essentially does not change when the additive is removed.

Fig. 7 zeigt eine Aufsicht auf das von der Erfindung vorgeschlagene Beimischgerät. Unmittelbar neben dem Beimischgerät ist ein Handgriff 49 angebracht, mit dem das Beimischgerät gehalten werden kann. An der dem Anschlußnippel 15 abgewandten Seite des Handgriffs 49 ist dieser mit einem Rohr 50 versehen, das aus Metall bestehen und einen Anschlußnippel zum Anbringen eines weiteren Gerätes aufweisen kann.7 shows a top view of the admixing device proposed by the invention. Immediately next to the admixer is a handle 49 with which the admixer can be held. On the side of the handle 49 facing away from the connecting nipple 15, the handle 49 is provided with a tube 50 which is made of metal and can have a connecting nipple for attaching a further device.

Das von der Erfindung vorgeschlagene Beimischgerät kann zum Zufügen beispielsweise von Waschmitteln bei Autowaschbürsten, von Dünger bei Düngegeräten und sonstigen Reinigungszusätzen bei anderen Reinigungsgeräten verwendet werden.The admixing device proposed by the invention can be used, for example, to add detergents to car wash brushes, fertilizers to fertilizers and other cleaning additives to other cleaning devices.
