Description

Die Erfindung betrifft einen Spender für die Abgabe einer aus wenigstens zwei Komponenten bestehenden Substanz mit den oberbegrifflichen Merkmalen des Anspruchs 1.The invention relates to a dispenser for dispensing a substance consisting of at least two components with the preamble features of claim 1.

Aus der EP 1 104 336 ist ein Dosierspender bekannt, bei dem das Mischungsverhältnis zweier pastöser oder flüssiger Fluidkomponenten stufenlos einstellbar ist. Der Dosierspender stellt für den Verbraucher, der das Mischungsverhältnis der Fluidkomponenten selbst wählen und auf seine persönlichen Bedürfnisse bzw. den Verwendungszweck der gemischten Komponenten abstimmen kann, eine erhebliche Erleichterung dar. Im Dosierspender sind hier zwei Kartuschen mit zugeordneten Pumpen vorgesehen, die über ein verschwenkbares Übertragungselement, dessen Schwenkachse relativ zu den Pumpen - bzw. deren Verdrängern - verschiebbar ist, betätigt werden.From the EP 1 104 336 a metering dispenser is known in which the mixing ratio of two pasty or liquid fluid components is infinitely adjustable. The dispenser provides the consumer, who can choose the mixing ratio of the fluid components themselves and vote on his personal needs or the intended use of the mixed components, a considerable relief. In the dispenser here two cartridges with associated pumps are provided, which via a pivotable transmission element whose pivot axis relative to the pumps - or their displacers - is displaceable, are actuated.

Nachteilig an dem bekannten Dosierspender ist, dass das Übertragungselement gleichzeitig zur Einstellung des Mischungsverhältnisses der Fluidkomponenten dient. Bei einem Ausfall des Übertragungselementes kann somit keine Entnahme mehr aus dem Dosierspender erfolgen. Zudem ist aufgrund der Doppelfunktion des Übertragungselementes dessen Aufbau und Montage relativ kompliziert.A disadvantage of the known metering dispenser is that the transfer element simultaneously serves to adjust the mixing ratio of the fluid components. In case of failure of the transmission element thus no removal can be done from the dosing dispenser. In addition, due to the dual function of the transmission element whose structure and installation is relatively complicated.

Es ist die Aufgabe der vorliegenden Erfindung, die Nachteile des Standes der Technik zu überwinden und einen Spender zur Verfügung zu stellen, der einen konstruktiv einfachen und montagefreundlichen Einstellmechanismus für das Mischungsverhältnis aufweist.It is the object of the present invention to overcome the disadvantages of the prior art and to provide a dispenser having a structurally simple and easy-to-assemble mixing ratio setting mechanism.

Advantageous developments of the invention are the subject of the dependent claims.

Die Behälter können dabei nach Art von Kartuschen, d. h. mit starrem Mantel, aber auch als elastische Flaschen oder Beutel ausgebildet sein. Eine Ausführungsform mit fester Verbindung der jeweiligen Behälter mit dem Spender ist ebenso vorgesehen, wie eine lösbare, den Austausch der Kartuschen und deren Bewegung bzw. Verschiebung im Spender während des Dosier- bzw. Abgabevorganges ermöglichende Ausführung. Die Gestaltung der Behälter richtet sich auch nach der Viskosität der Komponenten und deren Entnahmeverhalten. Weiterhin ist an jedem der Behälter eine Pumpeinheit angeordnet, über die eine Entnahme der jeweiligen Komponenten erfolgt. Die Pumpeinheiten können dabei als Kolbenpumpe, als Balgpumpe oder in einer sonstigen geeigneten Bauweise ausgeführt werden. Der erfindungsgemäße Spender umfasst weiterhin eine Einstelleinrichtung, mit der das Mengenverhältnis der Komponenten der zu dosierenden Substanz einstellbar ist, sowie eine bewegliche Betätigungseinrichtung für die Pumpeinheit und eine Spenderdüse für die vom Spender abgegebene Substanz.According to the invention, a dispenser is provided for dispensing a substance consisting of at least two components, wherein the dispenser comprises at least two containers for receiving the components of the substance. The containers can in the manner of cartridges, d. H. be formed with a rigid coat, but also as elastic bottles or bags. An embodiment with fixed connection of the respective container with the dispenser is also provided, as a detachable, the replacement of the cartridges and their movement or displacement in the dispenser during the dispensing or dispensing operation enabling execution. The design of the container also depends on the viscosity of the components and their removal behavior. Furthermore, a pump unit is arranged on each of the containers, via which a removal of the respective components takes place. The pump units can be designed as a piston pump, as a bellows pump or in any other suitable construction. The dispenser according to the invention further comprises an adjusting device with which the quantity ratio of the components of the substance to be metered is adjustable, as well as a movable actuating device for the pumping unit and a dispensing nozzle for the substance dispensed by the dispenser.

Der Spender ist dadurch gekennzeichnet, dass die Einstelleinrichtung in ihrem Abstand zu den Behältern bzw. den Pumpeinrichtungen oder im Abstand von an der Einstelleinrichtung vorgesehenen Vorsprüngen gegenüber einer Schwenkachse der Betätigungseinrichtung veränderbar ist, insbesondere gegenläufig. Bevorzugt ist eine um ihre Hochachse drehbare Keilscheibe, ein wendelartiger oder treppenartig abgestufter Keilring oder Ring mit Vorsprüngen, die beispielsweise dornartig ausgeführt sind, vorgesehen. Die drehbare Keilscheibe, der drehbare Keilring bzw. der Ring ist dabei fest oder lösbar mit der Betätigungseinrichtung verbunden bzw. dieser lose zugeordnet oder in Art eines Axiallagers auf dieser aufgelegt. Die drehbare Keilscheibe bzw. der drehbare Keilring ist mit einer gegenüber der Horizontalen angewinkelten Abstandsfläche und einer bevorzugt horizontal ausgerichteten Stützfläche ausgebildet, so dass diese Flächen einen spitzen Winkel einschließen. Im Verwendungszustand, d. h. beim Einbau der Einstelleinrichtung in einem Spender ist diese so angeordnet, dass die Abstandsfläche den Behältern oder den Pumpeinheiten und die Stützfläche der Betätigungseinrichtung zugewandt ist, jedoch in den meisten Dosiereinstellungen (außer bei 50:50) einen unterschiedlichen Abstand zu den Behältern bzw. Pumpeinrichtungen aufweisen.The dispenser is characterized in that the adjusting device is variable in its distance from the containers or the pumping means or at a distance from projections provided on the adjusting device relative to a pivot axis of the actuating device, in particular in opposite directions. Preference is given to a rotatable about its vertical axis wedge disk, a helical or stepped stepped wedge ring or ring with projections, which are designed, for example, like a mandrel provided. The rotatable wedge disk, the rotatable wedge ring or the ring is fixed or releasably connected to the actuator or this assigned loose or placed in the manner of a thrust bearing on this. The rotatable wedge disk or the rotatable wedge ring is formed with a relative to the horizontal angled spacer surface and a preferably horizontally oriented support surface, so that these areas include an acute angle. In use condition, ie when installing the adjuster in a dispenser, it is arranged so that the clearance surface faces the containers or pumping units and the actuator support surface, but in most dosing settings (except at 50:50) have different distance to the containers or pumping devices.

Eine Einstellung des Mischungsverhältnisses der Komponenten erfolgt durch Änderung der Relativposition der Keilscheibe, des Keilringes oder der Vorsprünge und der damit verbundenen Änderung des Abstands der Keilscheibe bzw. des Keilringes oder der Angriffspunkte der Vorsprünge an den Pumpeinheiten bzw. den Behältern oder Behälterböden. Bedingt durch die Ausbildung der Keilscheibe bzw. des Keilringes wird der Hub der Pumpeinheiten und damit die Menge der über die jeweiligen Pumpeinheit geförderten Komponente verändert. Die Ausgestaltung der Keilscheiben- bzw. Keilringfläche ist dabei so gewählt, dass eine gegenläufige Änderung der Komponentenabgabe herbeigeführt wird. Somit wird lediglich das Dosierungsverhältnis der Komponenten zueinander verstellt, die Gesamtfördermenge bleibt im Wesentlichen konstant. Vorstellbar ist jedoch auch, durch Verstellung der Position der Einstelleinrichtung relativ zu den Pumpeinheiten bzw. den Behältern oder durch Änderung der Höhe der Einstelleinrichtung, das Gesamtfördervolumen zu verstellen. Die beiden Komponenten können vermischt, insbesondere in einem Applikator nach der WO 2006/111273 oder ggf. auch unvermischt ausgetragen werden.An adjustment of the mixing ratio of the components takes place by changing the relative position of the wedge disk, the wedge ring or the projections and the associated change in the distance of the wedge disk or wedge ring or the points of application of the projections on the pumping units or the containers or container bottoms. Due to the design of the wedge disk or the wedge ring, the stroke of the pumping units and thus the amount of subsidized via the respective pumping unit component is changed. The design of the wedge disk or wedge ring surface is chosen so that an opposite change in the component delivery is brought about. Thus, only the metering ratio of the components is adjusted to each other, the total delivery rate remains substantially constant. However, it is also conceivable to adjust the total delivery volume by adjusting the position of the adjusting device relative to the pumping units or the containers or by changing the height of the adjusting device. The two components can be mixed, in particular in an applicator after the WO 2006/111273 or if necessary, also unmixed be discharged.

Der erfindungsgemäße Spender hat im Vergleich zu dem eingangs beschriebenen Dosierspender einen wesentlich einfacheren Aufbau, da die Einstelleinrichtung als gesonderte, einfach ausgeführte Einheit ausgebildet ist, die präzise einstellbar an den Pumpeinheiten angreift. Durch eine mögliche stehende Anordnung der Pumpeinheiten kann der Dosierspender kompakt ausgeführt werden. Neben einer unmittelbaren Beaufschlagung der Pumpeinheiten durch das Einstelleinrichtung bzw. die Betätigungseinrichtung besteht auch die Möglichkeit, die Pumpeinheiten fest im Spender anzuordnen und, vermittelt durch die Einstelleinrichtung bzw. die Betätigungseinrichtung eine Beaufschlagung der Behälter durchzuführen, die dann mit dem jeweils eingestellten Hub in die Pumpeinheiten gedrückt werden, wobei die Abgabe einer entsprechend dem Mischungsverhältnis definierten Komponentenmenge erfolgt.The dispenser according to the invention has a much simpler construction compared to the dispenser described above, since the adjustment is designed as a separate, simply executed unit that engages precisely adjustable on the pumping units. By a possible standing arrangement of the pumping units, the dosing dispenser can be made compact. In addition to an immediate loading of the pumping units by the setting or the actuator, it is also possible to arrange the pumping units fixed in the dispenser and, mediated by the adjustment or the actuator perform an application of the container, which then with the respective set stroke in the pumping units are pressed, wherein the delivery of a defined according to the mixing ratio component amount occurs.

Als vorteilhaft wird angesehen, wenn die Betätigungseinrichtung um eine senkrecht zur Hochachse der Keilscheibe, des Keilringes oder des Ringes und in der Ebene der Betätigungseinrichtung verlaufende Achse schwenkbar ausgebildet ist. Die Betätigungseinrichtung bleibt dabei in einer Achse in ihrem Abstand zu den Behältern bzw. Pumpeinheiten konstant und kann somit auch stets wieder in ihre Ausgangsposition zurückschwenken. In einer vorteilhaften Weiterbildung der Erfindung ist demgegenüber vorgesehen die Betätigungseinrichtung entlang der Hochachse der Keilscheibe, des Keilringes oder des Ringes verschiebbar auszubilden. Der Spender bzw. dessen äußerer Mantel dient dann als Axialführung für die Betätigungseinrichtung, die bei Betätigung in den Spender eintaucht, bis die durch die Einstelleinrichtung definierte maximale Verschiebetiefe erreicht ist und eine Abgabe der eingestellten Komponentenmenge im durch die Position der Einstelleinrichtung definierten Mischungsverhältnis aus den Behältern erfolgt ist.It is considered advantageous if the actuating device is designed to be pivotable about an axis extending perpendicularly to the vertical axis of the wedge disk, of the wedge ring or of the ring and in the plane of the actuating device. The actuator remains constant in an axis in their distance from the containers or pump units and thus can always swing back to its original position. In an advantageous embodiment of the invention, on the other hand, the actuating device is designed to be displaceable along the vertical axis of the wedge disk, the wedge ring or the ring. The dispenser or its outer jacket then serves as an axial guide for the actuating device which, when actuated in immersing the dispenser until the maximum depth of displacement defined by the adjusting device has been reached and dispensing of the adjusted component quantity has taken place in the mixing ratio defined by the position of the adjusting device from the containers.

Als empfehlenswert erweist es sich, die Einstelleinrichtung über die Betätigungseinrichtung verdrehbar auszubilden, da dann die Integration von Mengeneinstellung und Spenderbetätigung in einem Bauteil realisierbar ist. Daneben besteht jedoch, insbesondere bei einer getrennten Ausführung von Einstell- und Betätigungseinrichtung die Möglichkeit, dass die Einstelleinrichtung über eine gesonderte Drehhandhabe zur Verstellung des Mischungsverhältnisses verfügt. Als günstig erweist es sich in diesem Zusammenhang, wenn die Drehhandhabe am Umfang der Einstelleinrichtung, insbesondere am Umfang der Keilscheibe, des Keilringes oder Ringes angeordnet ist. Die Drehhandhabe kann dabei in vorteilhafter Weise als Betätigungs- oder Schiebehebel für die Einstellung der Verdrehposition der Einstelleinrichtung ausgebildet sein. Daneben besteht auch die Möglichkeit, dass eine Riffelung oder sonstige Aufrauhung am Umfang der Keilscheibe, des Keilringes oder des Ringes vorgesehen ist, wodurch das Verdrehen der Einstelleinrichtung wesentlich vereinfacht wird.It proves to be advisable to form the adjustment means rotatable about the actuator, since then the integration of quantity adjustment and dispensing operation in a component can be realized. In addition, however, there is the possibility, in particular in a separate embodiment of adjusting and actuating device, that the adjusting device has a separate rotary handle for adjusting the mixing ratio. As low proves it in this context, when the rotary handle on the circumference of the adjusting device, in particular on the circumference of the wedge disk, the wedge ring or ring is arranged. The rotary handle can be formed in an advantageous manner as an actuating or sliding lever for adjusting the rotational position of the adjusting device. In addition, there is also the possibility that a corrugation or other roughening on the circumference of the wedge disk, the wedge ring or the ring is provided, whereby the rotation of the adjusting device is substantially simplified.

Durch die Verstellung der Position von Flächenabschnitten der Keilscheibe bzw. des Keilringes oder der Position von Vorsprüngen am Ring mit Bezug zu den Pumpeinheiten führt die Einstelleinrichtung während des Verstellvorganges praktisch eine gewindegang- oder wendelartige Taumelbewegung gegenüber den Pumpeinheiten durch, wobei der Abstand und damit Angriffspunkt der Einstelleinrichtung an den Pumpeinheiten verändert wird. Als günstig wird angesehen, wenn die Einstelleinrichtung stufenlos verdrehbar ausgebildet ist oder aber eine Vielzahl von Rastpositionen zur definierten Verdrehung der Einstelleinrichtung aufweist. Bei der Ausgestaltung mit stufenloser Verdrehbarkeit der Einstelleinrichtung kann eine freie Wahl des Mischungsverhältnisses erfolgen. Bei der genannten Definition von Rastpositionen werden einstellbare Mischungsverhältnisse vorgegeben, wobei sich die Anzahl an Rastpositionen an der letztendlich angestrebten Auflösung des Mischungsverhältnisses orientiert.By adjusting the position of surface portions of the wedge disk or the wedge ring or the position of projections on the ring with respect to the pumping units, the adjustment during the adjustment practically performs a thread or helical wobbling movement with respect to the pumping units, wherein the distance and thus point of the Adjustment is changed at the pump units. As low is considered when the adjustment is formed continuously rotatable or has a plurality of locking positions for the defined rotation of the adjustment. In the embodiment with stepless rotatability of the adjustment can be done a free choice of the mixing ratio. In the above definition of locking positions adjustable mixing ratios are given, with the number of locking positions based on the ultimate desired resolution of the mixing ratio.

In vorteilhafter Weise ist die Betätigungseinrichtung im Wesentlichen ring- oder scheibenförmig, als Hülse oder als Druckknopf ausgebildet. Ferner kann diese gegen die Pumpeinheiten bzw. die Behälter eine Vorspannung aufweisen, um zügig anzusprechen und um nach dem Dosiervorgang wieder in ihre Ruhe- oder Ausgangsposition zurückzukehren.Advantageously, the actuator is substantially annular or disc-shaped, designed as a sleeve or as a push button. Furthermore, this may have a bias against the pumping units or the container in order to respond quickly and to return to its rest or initial position after the dosing process.

Beim eingangs beschriebenen Stand der Technik erfolgte durch die Betätigungseinrichtung stets eine direkte Einwirkung auf beide Pumpeinheiten, d. h. es besteht ein dauernder Kontakt. Die erfindungsgemäße Vorrichtung sieht hingegen vor, dass die Behälter oder die Pumpeinheiten durch unterschiedlichen Abstand (außer in der Mittelposition) quasi zeitversetzt durch die Einstelleinrichtung beaufschlagt sind, wobei das Verhältnis der Beaufschlagung der beiden Behälter oder der Pumpeinheiten abhängig ist von der Drehposition der Keilscheibe bzw. des Keilringes und der dadurch definierten Abstandsfläche zu den jeweiligen Behältern oder Pumpeinheiten.The prior art described at the beginning was carried out by the actuating device always a direct action on both pumping units, ie there is a permanent contact. The device according to the invention, on the other hand, provides that the containers or the pumping units are acted upon at different intervals (except in the middle position) by the adjusting device, with the ratio of the loading of the two containers or the pumping units being dependent on the rotational position of the wedge disk or the wedge ring and the distance surface defined thereby to the respective containers or pumping units.

Eine Weiterbildung der Erfindung sieht mit Blick auf die in der Vorrichtung vorgesehenen Auslaßeinrichtungen vor, dass diese einerseits mit je einer Pumpeinheit und andererseits mit der Spenderdüse verbunden bzw. in dieser zusammengeführt sind. Der Spender lässt sich damit besonders kompakt und mit geringer Axiallänge bilden. Es besteht auch die Möglichkeit, dass eine der Spenderdüse vorgelagerte Mischkammer vorgesehen ist, in die die Auslasseinrichtungen münden. Diese Mischkammer kann dann beispielsweise im Bereich zwischen den Pumpeinheiten oder den Behältern angeordnet werden.A development of the invention provides, with regard to the outlet devices provided in the device, that they are connected on the one hand to a respective pumping unit and on the other hand to the dispensing nozzle or brought together in this. The dispenser can thus be made particularly compact and with a low axial length. There is also the possibility that a mixing chamber upstream of the dispensing nozzle is provided into which the outlet devices open. This mixing chamber can then be arranged, for example, in the area between the pumping units or the containers.

Anhand der 1A bis 1F soll zunächst das Grundkonzept des erfindungsgemäßen Spenders 10 beschrieben werden, gemäß dem die Einstellung der Mischung durch Verdrehen oder Verschieben einer Einstelleinrichtung 38 gegenüber einer Betätigungseinrichtung 40 erfolgt. Die Einstelleinrichtung 38 ist auch gegenüber mehreren Pumpeinheiten 12a, 12b verdrehbar und im Ausführungsbeispiel mit einem Keilring ausgeführt. Der Keilring der Einstelleinrichtung 38 wird über die Betätigungseinrichtung 40 gegen die Pumpeinheiten 12a, 12b gepresst. Im Ausführungsbeispiel ist der Keilring drehbar mit der Betätigungseinrichtung 40 zu einer Einheit verbunden. Der drehbare Keilring der Einstelleinrichtung 38 ist mit einer gegenüber der Horizontalen angewinkelten Abstandsfläche 41 und einer horizontalen Stützfläche 42 ausgebildet, wobei vorgesehen ist, dass die diese Flächen 41 , 42 ausgehend von einem Ringbereich mit maximaler Höhe, einen spitzen Winkel α von hier etwa 20° Steigung einschließen. Die Einstelleinrichtung 38 ist so angeordnet, dass die Abstandsfläche 41 den Behältern 66 oder Pumpeinheiten 12a, 12b und die Stützfläche 42 der Betätigungseinrichtung 40 zugewandt ist.The basic concept of the dispenser 10 according to the invention will first be described with reference to FIGS. 1A to 1F, according to which the adjustment of the mixture takes place by rotating or displacing an adjusting device 38 relative to an actuating device 40. The adjusting device 38 is also rotatable with respect to a plurality of pump units 12a, 12b and executed in the embodiment with a wedge ring. The wedge ring of the adjuster 38 is pressed by the actuator 40 against the pumping units 12a, 12b. In the exemplary embodiment, the wedge ring is rotatably connected to the actuator 40 to form a unit. The rotatable wedge ring of the adjusting device 38 is formed with an angled relative to the horizontal distance surface 41 and a horizontal support surface 42, wherein it is provided that these surfaces 41, 42 starting from a ring area with maximum height, an acute angle α from here about 20 ° Include slope. The adjustment device 38 is arranged such that the spacer surface 41 faces the containers 66 or pumping units 12a, 12b and the support surface 42 of the actuating device 40.

Die Betätigungseinrichtung 40 ist hier beispielhaft um eine senkrecht zur Hochachse H (vgl. 1a) des Keilringes und etwa in der Ebene der Betätigungseinrichtung 40 verlaufende Schwenkachse 43 schwenkbar ausgebildet. Die Betätigungseinrichtung 40 bleibt dabei in ihrem Abstand zu den Behältern 66a, 66b bzw. Pumpeinheiten 12a, 12b konstant und kann somit stets wieder in ihre Ausgangsposition zurückschwenken. Dabei ist die Schwenkachse 43 an der Betätigungseinrichtung 40 befestigt und im Spender 10 festgelegt, also gegenüber dem Stand der Technik nicht um eine Hochachse verdrehbar, sondern stationär, wodurch die Montage erheblich vereinfacht wird. Gemäß den 1A bis 1F weist die Einstelleinrichtung 38 für einen erfindungsgemäßen Spender 10 einen Keilring auf. Die Einstelleinrichtung 38 ist um eine in 1A strichpunktiert veranschaulichte Hochachse H drehbar und weiterhin entlang der Hochachse H verschiebbar. Die Einstelleinrichtung 38 liegt in ihrer Mittelstellung mit ihrer Abstandsfläche 41 an Kolben 26 zweier Pumpeinheiten 12a und 12b an bzw. ist in Anlage bringbar, so dass in 1A zeitlich versetzt ein Pumpenhub erfolgt, nämlich zuerst am rechten Kolben und dann mit Abstand am linken Kolben. Die Betätigung erfolgt im dargestellten Ausführungsbeispiel durch Drücken auf die Betätigungseinrichtung 40 und deren Verschwenken um die stationäre Schwenkachse 43.The actuating device 40 is designed to be pivotable by way of example here about a pivot axis 43 running perpendicular to the vertical axis H (see FIG. 1a) of the wedge ring and approximately in the plane of the actuating device 40. The actuator 40 remains constant in their distance from the containers 66a, 66b and pump units 12a, 12b and thus can always swing back to its original position. In this case, the pivot axis 43 is attached to the actuator 40 and fixed in the dispenser 10, so compared to the prior art, not rotatable about a vertical axis, but stationary, whereby the assembly is considerably simplified. According to FIGS. 1A to 1F, the adjusting device 38 for a dispenser 10 according to the invention has a wedge ring. The adjusting device 38 is rotatable about a vertical axis H illustrated in phantom in FIG. 1A and furthermore displaceable along the vertical axis H. The adjusting device 38 is in its center position with its spacer surface 41 on piston 26 of two pumping units 12a and 12b or can be brought into contact, so that in Fig. 1A staggered a pump stroke takes place, namely first on the right piston and then at a distance on the left piston. The actuation takes place in the illustrated embodiment by pressing on the actuator 40 and pivoting about the stationary pivot axis 43rd

Die 1A, 1C und 1E zeigen jeweils den Zustand, in dem die Betätigungseinrichtung 40 , die im Ausführungsbeispiel ebenfalls ring- oder scheibenförmig ausgeführt ist, nicht um die Schwenkachse 43 verschwenkt ist und die 1B, 1D und 1F zeigen jeweils Zustände, in welchen die Betätigungseinrichtung 40 um die Schwenkachse 43 nach unten gedrückt und verschwenkt ist.1A, 1C and 1E respectively show the state in which the actuator 40, which is also annular or disk-shaped in the embodiment, is not pivoted about the pivot axis 43, and Figs. 1B, 1D and 1F respectively show conditions in which the actuator 40 is pressed down about the pivot axis 43 and pivoted.

Das Verschwenken oder Niederdrücken der Betätigungseinrichtung 40 um die Schwenkachse 43 kann über einen per Hand betätigbaren Abschnitt 62 am Düsenkopf 46 erfolgen, in welchem auch die Austritts- oder Spenderdüse 52 (vgl. 4) für die Mischung angeordnet sein kann. Weiterhin kann die Einstelleinrichtung 38 mit diesem Düsenkopf 46 gedreht werden, so dass sich der an den Pumpeinheiten 12a und 12b anliegende bzw. an diese anlegbare Flächenbereich des Keilringes der Einstelleinrichtung 38 ändert, wie unmittelbar aus den 1A bis 1F hervorgeht. Die Betätigungseinrichtung 40 kann mittels der Schwenkachse 43 in einer Lagerung oder Halterung gelagert sein, welche drehfest mit dem Düsenkopf 46 verbunden ist. Bei einer entsprechenden Drehung der Einstelleinrichtung 38 wird diese unterhalb der Betätigungseinrichtung 40 verdreht und damit das neue Mischungsverhältnis eingestellt. Die Ringfläche 42 zwischen diesen Bauteilen wirkt dabei wie eine Axiallagerfläche, die eine Relativverdrehung des Keilrings der Einstelleinrichtung um die Hochachse H zulässt.The pivoting or depression of the actuating device 40 about the pivot axis 43 can take place via a manually operable section 62 on the nozzle head 46, in which also the outlet or dispensing nozzle 52 (see Fig. 4) can be arranged for the mixture. Furthermore, the adjusting device 38 can be rotated with this nozzle head 46, so that the voltage applied to the pump units 12a and 12b or can be applied to this surface area of the wedge ring of the adjusting 38 changes, as is apparent directly from the 1A to 1F. The actuating device 40 may be mounted by means of the pivot axis 43 in a bearing or holder which is rotatably connected to the nozzle head 46. With a corresponding rotation of the adjusting device 38, this is rotated below the actuator 40 and thus set the new mixing ratio. The annular surface 42 between these components acts like an axial bearing surface, which allows a relative rotation of the wedge ring of the adjusting device about the vertical axis H.

Wird die Einstelleinrichtung 38 entsprechend der Position in 1A, beispielsweise durch Niederdrücken des Betätigungsabschnitts 62 am Düsenkopf 46 bzw. der Betätigungseinrichtung 40 nach unten gedrückt, wird nur der Verdränger bzw. Kolben 26 der in 1B rechten Pumpeinheit 12b niedergedrückt. Hierdurch hat die Pumpeinheit 12b einen Hub oder ein Fördervolumen von 100%. Die hier linke Pumpeinheit 12a, welche nicht mit einer Kraft beaufschlagt wird, da sie unterhalb der Fläche 42 mit dem kürzesten Abstand zwischen erster und zweiter Fläche 41, 42 und somit der geringsten Höhe des Keilringes liegt, hat einen Hub- oder ein Fördervolumen von 0% (bezogen auf die Gesamtausgabemenge). Die Austragsmenge enthält nur Bestandteile der von der Pumpeinheit 12b geförderten Komponente. Wird die Einstelleinrichtung 38 beispielsweise über den Düsenkopf 46 oder eine andere geeignete Vorrichtung um 180° gegenüber der in 1A gezeigten Position gedreht, nimmt die Einstelleinrichtung 38 in ihrer Neutralstellung die Lage gemäß 1C ein, in der der Flächenbereich mit der größten Höhe des Keilringes am Verdränger 26 der linken Pumpeinheit 12a anliegt. Wird ausgehend von der Position gemäß 1C die Betätigungseinrichtung 40 um die Schwenkachse 43 nach unten verschwenkt, dann führt nun die linke Pumpeinheit 12a einen Hub durch (Fördervolumen 100%), während die rechte Pumpeinheit 12b keinen Hub durchführt oder ein Fördervolumen von 0% hat. Die Austragsmenge enthält nur Bestandteile der von der Pumpeinheit 12a geförderten Komponente.1A, for example, by depressing the operating portion 62 on the nozzle head 46 and the actuator 40, respectively, the plunger 26 of the pump unit 12b on the right in FIG. 1B is depressed. As a result, the pump unit 12b has a stroke or a delivery volume of 100%. The here left pump unit 12a, which is not acted upon by a force, since it is below the surface 42 with the shortest distance between the first and second surfaces 41, 42 and thus the lowest height of the wedge ring, has a lifting or a delivery volume of 0 % (relative to the total issue quantity). The discharge amount contains only components of the funded by the pumping unit 12 b component. If the adjusting device 38 is rotated by 180 ° relative to the position shown in FIG. 1A, for example via the nozzle head 46 or another suitable device, the setting device 38 assumes the position according to FIG. 1C in its neutral position, in which the surface area with the greatest height of the wedge ring on the displacer 26 of the left pump unit 12a is applied. If, starting from the position according to FIG. 1C, the actuating device 40 is pivoted down about the pivot axis 43, then the left pump unit 12a performs a stroke (delivery volume 100%), while the right pump unit 12b does not carry out a stroke or has a delivery volume of 0%. The discharge quantity contains only components of the component conveyed by the pump unit 12a.

Bei einer Verdrehung der Einstelleinrichtung 38 ausgehend von der Position gemäß 1A oder 1C um 90° in eine Mittelstellung zwischen den beiden vorher genannten Extremen wird eine Ausrichtung des Keilringes der Einstelleinrichtung 38 gemäß 1E erhalten. In dieser Mittelstellung hat die Abstandsfläche 41 den gleichen Abstand zu beiden Pumpeinheiten 12a und b. Wird ausgehend von der Position gemäß 1E die Einstelleinrichtung 38 nach unten gedrückt, werden die beiden Verdränger 26 der Pumpeinheiten 12a , 12b um den gleichen Weg nach unten gedrückt, so dass beide Pumpeinheiten 12a , 12b zeitgleich einen identischen Hub oder ein Fördervolumen von 50% der Gesamtausgabemenge haben. Die Mischung enthält gleiche Teile der beiden Komponenten. Bei Zwischenpositionen der Einstelleinrichtung 38 zwischen den vorstehend genannten Stellungen ergeben sich entsprechende Zwischenverhältnisse zwischen den Hüben oder Fördervolumina der Pumpeinheiten 12a, 12b, so dass diese für jede Komponente zwischen 0%:100% und 100%:0% stufenlos veränderbar sind.Upon rotation of the adjusting device 38 from the position according to FIG. 1A or 1C by 90 ° to a middle position between the two aforementioned extremes, an alignment of the wedge ring of the adjusting device 38 according to FIG. 1E is obtained. In this middle position, the spacing surface 41 has the same distance to both pumping units 12a and b. If, starting from the position according to FIG. 1E, the adjusting device 38 is pressed down, the two displacers 26 of the pumping units 12a, 12b are pressed downwards by the same distance, so that both pumping units 12a, 12b simultaneously have an identical stroke or a delivery volume of 50% Have total output quantity. The mixture contains equal parts of the two components. At intermediate positions of the adjusting device 38 between the above-mentioned positions, corresponding intermediate ratios between the strokes or delivery volumes of the pumping units 12a, 12b result, so that they are infinitely variable between 0%: 100% and 100%: 0% for each component.

Bei der vorbeschriebenen Konstruktion ist die Schwenkachse 43 als tangential aus der Umfangskante der ring- oder plattenförmigen Betätigungseinrichtung 40 hervorstehende Lagerzapfen ausgebildet. Es handelt sich um eine Art Schwenkhandhabe, während nachfolgend die translatorische Betätigung in Art einer Axialführung beschrieben wird.In the above construction, the pivot shaft 43 is formed as a tangent protruding from the peripheral edge of the annular or plate-shaped actuator 40 journal. It is a kind of pivoting handle, while below the translational actuation is described in the manner of an axial guide.

Bei dem in den 2A bis 2F dargestellten Ausführungsbeispiel liegt eine Integration von Einstelleinrichtung 38 aus den 1A bis 1F in die Betätigungseinrichtung 40 vor. Hier erfolgt ein axiales Verschieben der kombinierten Einstell-/Betätigungseinrichtung 47 entlang deren Hochachse H. Zur Einstellung des Mischungsverhältnisses wird die Einstell-/Betätigungseinrichtung 47 verdreht und dabei die entsprechenden Flächenabschnitte wie oben bereits ausgeführt über den Pumpeinheiten 12a, 12b bzw. den zugehörigen Verdrängern 26 positioniert. Die Einstell-/Betätigungseinrichtung 47 ist beim dargestellten Konstruktionskonzept als ringförmiger Hohlkörper ausgebildet, der mit seiner den Pumpeinheiten 12a, 12b zugewandten, wendelförmigen Oberfläche 70 (mit dem Steigungswinkel α von ca. 15°) zu den Kolben 26 hin translatorisch (vgl. vertikaler Doppelpfeil in 2A) bewegbar ist.In the embodiment illustrated in FIGS. 2A to 2F, integration of adjuster 38 of FIGS. 1A to 1F into actuator 40 is present. Here, an axial displacement of the combined setting / actuating device 47 takes place along its vertical axis H. To adjust the mixing ratio, the setting / actuating device 47 is rotated and thereby the corresponding surface sections as already stated above the pumping units 12a, 12b and the associated displacers 26th positioned. The adjustment / actuation device 47 is formed in the illustrated construction concept as an annular hollow body, with its the pump units 12a, 12b facing, helical surface 70 (with the pitch angle α of about 15 °) to the piston 26 out translationally (see vertical double arrow in Fig. 2A).

3A zeigt eine weitere Prinzipdarstellung der erfindungsgemäßen Einstelleinrichtung 38, die hier direkt auf die Bodenflächen 67 von Behältern 66a, 66b einwirkt. Anstelle eines keilförmigen Elements weist die Einstelleinrichtung 38 im Ausführungsbeispiel dornartige Vorsprünge 61a, 61b auf, die durch Verschwenken der Betätigungseinrichtung 40 an die Bodenflächen 67 der Behälter 66a, 66b zeitversetzt anlegbar sind. In Abhängigkeit von der Verdrehposition der Einstelleinrichtung 38 wird einer der dornartigen Vorsprünge (hier 61b), wie in 3A dargestellt, unter der Schwenkachse 43 positioniert, so dass hier beispielsweise bei Niederdrücken der Betätigungseinrichtung 40 keine Beaufschlagung des in 3A rechten Behälters 66a erfolgt. 3B bis 3D zeigt schematisch die Wirkung verschiedener Einstellpositionen bzw. Positionierungen der dornartigen Vorsprünge 61a, 61b unterhalb der schematisch angedeuteten Schwenkachse 43 auf die Substanzabgabe bzw. Mischungsverhältnisse der Komponenten.3A shows a further basic illustration of the setting device 38 according to the invention, which acts directly on the bottom surfaces 67 of containers 66a, 66b. Instead of a wedge-shaped element, the adjusting device 38 in the exemplary embodiment on mandrel-like projections 61 a, 61 b, by pivoting the actuator 40 to the bottom surfaces 67 of the container 66a, 66b can be applied with a time delay. Depending on the rotational position of the adjusting device 38, one of the thorn-like projections (here 61b), as shown in FIG. 3A, is positioned below the pivot axis 43 so that, for example, upon depression of the actuating device 40, there is no loading of the right-hand container 66a in FIG. 3A. FIGS. 3B to 3D schematically show the effect of different setting positions or positioning of the pin-like projections 61a, 61b below the schematically indicated pivot axis 43 on the substance delivery or mixing ratios of the components.

Bei den Ausführungsbeispielen der 1 und 2 wurden die Kolben bzw. Verdränger 26 der Pumpeinheiten 12a, 12b mittelbar oder unmittelbar über die Betätigungseinrichtung 40 bzw. die Einstelleinrichtung 38 betätigt. Eine kinematische Umkehr kann darin bestehen, dass die Einstelleinrichtung 38 auf die bewegbar im Gehäuse 48 geführten Behälter 66a, 66b wirkt und diese wiederum die Pumpeinheiten 12a, 12b beaufschlagen. Dabei können die Verdränger 26 feststehend in einem Gehäuse 48 gelagert sein, während die Behälter 66a, 66b verschiebbar sind. Umgekehrt können auch die Verdränger 26 mit den Behältern 66a, 66b verbunden im Gehäuse 48 gelagert sein.In the embodiments of FIGS. 1 and 2, the pistons or displacers 26 of the pumping units 12a, 12b have been actuated indirectly or directly via the actuating device 40 or the adjusting device 38. A kinematic reversal may consist in that the adjusting device 38 acts on the containers 66a, 66b which are movably guided in the housing 48 and in turn act on the pumping units 12a, 12b. In this case, the displacers 26 can be mounted fixedly in a housing 48, while the containers 66a, 66b are displaceable. Conversely, the displacers 26 may be mounted in the housing 48 connected to the containers 66a, 66b.

4zeigt eine stark vereinfachte Ansicht eines erfindungsgemäßen Spenders 10 mit einem Gehäuse 48 , in dem im Folgenden noch näher beschriebene Behälter 66a , 66b (vgl. 3A) für die Komponenten aufgenommen sind. Das Gehäuse 48 trägt den drehbaren Gehäusekopf 46, an dem eine Spenderdüse 52 ausgebildet ist. Durch diese tritt die über den Hub der Pumpeinheiten 12a, 12b eingestellte Mischung aus. Die Einstellung der Mischung erfolgt durch Verdrehen einer dem Düsen- oder Gehäusekopf 46 zugeordneten Einstelleinrichtung 38 mit Bezug zum Gehäuse 48 , wobei beispielsweise am Düsen- oder Gehäusekopf 46 eine Markierung 56 aufgebracht ist, die mit einer Skala 58 in Überdeckung gebracht wird, um ein vorbestimmtes Dosierverhältnis einzustellen. Bei dem in 4 dargestellten Ausführungsbeispiel soll das anhand der 1A bis 1F angedeutete Erfindungskonzept realisiert sein d. h., die Einstelleinrichtung 38 wird unabhängig vom übrigen Düsen- oder Gehäusekopf 46 verdreht.4 shows a greatly simplified view of a dispenser 10 according to the invention with a housing 48, in which containers 66a, 66b (see FIG. The housing 48 carries the rotatable housing head 46, on which a dispensing nozzle 52 is formed. Through this occurs over the stroke of the pumping units 12a, 12b set mixture. The adjustment of the mixture is made by rotating an adjustment device 38 associated with the nozzle or housing head 46 with respect to the housing 48, for example with a marking 56 applied to the nozzle or housing head 46 which is brought into registration with a scale 58 to a predetermined one Adjust dosing ratio. In the exemplary embodiment illustrated in FIG. 4, the concept of the invention indicated on the basis of FIGS. 1A to 1F is intended to be realized d. h., The adjuster 38 is rotated independently of the rest of the nozzle or housing head 46.

Bei dem dargestellten Ausführungsbeispiel ist im Bereich der Umfangskante der Stirnfläche 54 ein Durchbruch 60 ausgebildet, so dass ein Bestätigungsabschnitt 62 der Betätigungseinrichtung 40 freigeschnitten wird. Dieser Betätigungsabschnitt 62 steht im maximalen Abstand zur schematisch angedeuteten Schwenkachse 43, so dass die Betätigungseinrichtung 40 durch Aufbringen einer Betätigungskraft auf den Betätigungsabschnitt 62 verschwenkbar und somit ein Förderhub der Pumpeinheiten 12a, 12b herbeigeführt wird. Selbstverständlich kann der freigeschnittene Düsen- oder Gehäusekopf 46 auch bei dem in 2A, 2B dargestellten Ausführungsbeispiel mit Einstell-/Betätigungseinrichtung 47 verwendet werden. Alternativ könnte der Gehäusekopf 46 auch axial verschiebbar auf dem Gehäuse 48 geführt sein, wobei beispielsweise an der Innenfläche des Düsen- oder Gehäusekopfes 46 ein Betätigungsbolzen ausgebildet ist, der durch das Axialverschieben des Gehäusekopfes 46 in Anlage an den die Einstelleinrichtung 38 bringbar ist, so dass ein Verschieben entlang deren Hochachse H erfolgt.In the illustrated embodiment, an opening 60 is formed in the region of the peripheral edge of the end face 54, so that a confirmation section 62 of the actuating device 40 is cut free. This actuating portion 62 is at the maximum distance to the schematically indicated pivot axis 43, so that the actuator 40 by applying an actuating force on the actuating portion 62 pivotally and thus a delivery stroke of the pumping units 12a, 12b is brought about. Of course, the cut-out nozzle or housing head 46 can also be used in the exemplary embodiment shown in FIGS. 2A, 2B with setting / actuating device 47 are used. Alternatively, the housing head 46 could also be axially displaceably guided on the housing 48, wherein, for example, on the inner surface of the nozzle or housing head 46, an actuating pin is formed, which is brought by the axial displacement of the housing head 46 into abutment with the adjusting device 38, so that a displacement along the vertical axis H takes place.

Ein auf einer "kinematischen Umkehr" basierendes Ausführungsbeispiel ist in 5A schematisch dargestellt. Demgemäß sind in dem Gehäuse 48 des Spenders 10 wiederum zwei Pumpeinheiten 12a, 12b aufgenommen, die in Kolbenbauweise ausgeführt sind. Die Verdränger 26 sind feststehend im Gehäuse 48 gelagert und als sogenannte Hohlkolben ausgeführt, wobei die Auslass- oder Druckventile in einem mit dem Verdränger 26 verbundenen Druckkanal 74 ausgebildet sind. Die einzelnen Druckkanäle 74 der Pumpeinheiten 12a, 12b können in einem gemeinsamen Mischkanal 96 münden. Die Pumpeinheiten 12a, 12b sind axial verschiebbar im Gehäuse 48 angeordnet und an jeweils einer Kartusche 102 befestigt, in denen die Komponenten aufgenommen sind. Im Übergangsbereich der Kartusche 102 ist ein Saugventil 72 ausgebildet, so dass eine Rückströmung der Komponente vom Verdrängerraum 68 in die Kartusche 102 verhindert ist. Die Kartuschen 102 sind axial verschiebbar im Gehäuse 48 geführt.An embodiment based on a "kinematic reversal" is shown schematically in FIG. 5A. Accordingly, in the housing 48 of the dispenser 10 again two pumping units 12a, 12b are added, which are designed in piston design. The displacers 26 are fixedly mounted in the housing 48 and designed as a so-called hollow piston, wherein the outlet or pressure valves are formed in a connected to the displacer 26 pressure channel 74. The individual pressure channels 74 of the pumping units 12a, 12b can open into a common mixing channel 96. The pump units 12a, 12b are arranged axially displaceable in the housing 48 and fastened to a respective cartridge 102, in which the components are accommodated. In the transition region of the cartridge 102, a suction valve 72 is formed, so that a backflow of the component from the displacement chamber 68 into the cartridge 102 is prevented. The cartridges 102 are guided axially displaceably in the housing 48.

Die Einstelleinrichtung 38 ist hier in dem von den Pumpeinheiten 12a , 12b entfernten Bereich des Gehäuses 48 gelagert und wiederum um ihre Hochachse H drehbar, nämlich mit einem aus dem Gehäuse 48 (hier nach oben) herausragenden kombinierten Druck- und Drehknopf. Im Unterschied zu den vorgenannten Ausführungsbeispielen wirkt die Einstelleinrichtung 38 nicht auf die Verdrängen 26, sondern auf die Kartuschen 102, so dass diese bei einer Verschiebung der Einstelleinrichtung 38 in Axialrichtung verschoben werden. Durch diese Axialverschiebung der Kartuschen 102 werden diese auch gegenüber den Verdrängern 26 verschoben, so dass der Verdrängerraum 68 verkleinert (Förderhub) bzw. vergrößert wird (Saughub). Die Übertragung der Schubbewegung der Einstelleinrichtung 38 erfolgt bei dem dargestellten Ausführungsbeispiel über Anlagezapfen 106 , die an den Böden der Kartuschen 102 ausgebildet sind und der Abstandsfläche 41 mit unterschiedlichem Abstand gegenüberliegen (nur in Mittelstellung ist der Abstand gleich). Hierbei ist die wendelartige Gestaltung der Abstandsfläche 41 gut erkennbar, wobei auch eine treppenartig abgestufte Gestaltung dieser gewindegangartigen Fläche möglich ist, wenn anstatt einer stufenlosen Verstellung eine Einstellung in vielen Stufen gewünscht wird.The adjusting device 38 is mounted here in the region of the housing 48 remote from the pumping units 12a, 12b and in turn rotatable about its vertical axis H, namely with a combined pressure and rotary knob protruding from the housing 48 (here upward). In contrast to the aforementioned embodiments, the adjusting device 38 does not act on the displacements 26, but on the cartridges 102, so that they are displaced in the axial direction during a displacement of the adjusting device 38. As a result of this axial displacement of the cartridges 102, they are also displaced relative to the displacers 26, so that the displacer space 68 is reduced (delivery stroke) or increased (suction stroke). The transmission of the thrust movement of the adjusting device 38 takes place in the illustrated embodiment via journals 106 which are formed on the bottoms of the cartridges 102 and the spacer surface 41 with different distances opposite each other (only in the middle position, the distance is equal). Here, the helical design of the spacer surface 41 is clearly visible, with a stepped-like design of this thread-like surface is possible if instead of a continuous adjustment, a setting in many stages is desired.

Im vorbeschriebenen Ausführungsbeispiel werden die Komponenten einer gemeinsamen, zentralen Mischkammer 92 zugeführt. Prinzipiell könnten die einzelnen Komponenten jedoch auch getrennt voneinander zum Mischkanal 96 bzw. zur Spenderdüse 52 geführt werden, so dass keine innere Durchmischung stattfindet. Die Spenderdüse 52 kann in Radialrichtung oder zentral aus der Stirnfläche 54 austreten. Wie vorstehend angeführt ist jedoch bevorzugt ein Applikator nach der WO 2006/111273 vorgesehen, da hierdurch eine besonders intensive Vermischung möglich ist. Um die Betätigungskräfte beim Mischen hochviskoser Komponenten zu reduzieren, können geeignete Handhaben an der Betätigungseinrichtung 40 befestigt werden, durch die sich eine größere Hebelwirkung erzielen lässt.In the above-described embodiment, the components of a common, central mixing chamber 92 are supplied. In principle, however, the individual components could also separated from each other to the mixing channel 96 and the dispensing nozzle 52 are guided so that there is no internal mixing. The dispensing nozzle 52 may exit in the radial direction or centrally from the end face 54. As stated above, however, an applicator according to the WO 2006/111273 provided, as a result, a particularly intensive mixing is possible. In order to reduce the actuation forces when mixing highly viscous components, suitable handles can be attached to the actuator 40, which can achieve greater leverage.

Ein Beispiel hierzu ist in 5B gezeigt, wobei der Druck- und Drehknopf als kombinierte Betätigungseinrichtung 40 und Einstellelement 38 einen größeren Durchmesser als in 5A aufweist. Da der Aufbau des Dosierspenders 10 ansonsten gleich ist, sind nur die wesentlichen Bezugszeichen eingefügt. Gleiches gilt auch für die in 5C dargestellte Ausführung des Dosierspenders 10, der hier ""Überkopf" angeordnet ist, wobei die strichliert angedeutete Spenderdüse 52 radial seitlich herausgeführt ist. In 5C ist der Durchmesser so weit maximiert, dass die Außenhülle des Gehäuses 48 als gut greifbare Drehhülse, also als Einstellelement 38 ausgebildet ist, die beim Zusammendrücken bzw. Axialhub entsprechend dem Pfeil als großflächiges Betätigungselement 40 dient. In der Ausführung nach 5D ist ähnlich wie bei 5B ein relativ großer Druck- und Drehknopf als kombinierte Betätigungseinrichtung 40 und Einstelleinrichtung 38 vorhanden, wobei hier die Abstandsfläche 41 als Keilfläche ausgebildet ist.An example of this is shown in Fig. 5B where the push and turn knob as combined actuator 40 and adjustment member 38 has a larger diameter than in Fig. 5A. Since the structure of the dosing dispenser 10 is otherwise the same, only the essential reference numerals are inserted. The same applies to the embodiment of the dosing dispenser 10 shown in Fig. 5C, which is arranged "overhead", with the dispensing nozzle 52 indicated by dashed lines extending radially to the side .. In Fig. 5C, the diameter is maximized to the extent that the outer shell of the housing 48 is good a tangible rotating sleeve, that is designed as an adjusting element 38, which serves as a large-area actuating element 40 during compression or axial stroke corresponding to the arrow in the embodiment of Fig. 5D is similar to 5B, a relatively large pressure and rotary knob as a combined actuator 40 and adjuster 38 is present , wherein here the spacer surface 41 is formed as a wedge surface.

In 5Eist der Dosierspender 10 ähnlich wie 5C dimensioniert und aufgebaut, jedoch wird hierbei die in Zusammenhang mit 3A beschriebene feststehende Schwenkachse 43 mit angrenzender Einstelleinrichtung 38 verwendet, an der wiederum die Vorsprünge 61a , b zur Beaufschlagung der Kartuschen angeformt sind. Dieser Aufbau wird auch in dem Dosierspender 10 nach 5F verwendet, wobei der Dreh- und Druckknopf 104 als Betätigungseinrichtung 40 und Einstellelement 38 ähnlich zu 5A ausgebildet ist. In der zugehörigen Draufsicht ist auch der Verlauf der Schwenkachse 43 gut erkennbar.In Fig. 5E, the dispenser 10 is sized and constructed similar to Fig. 5C, but using the fixed pivot axis 43 described in connection with Fig. 3A with adjacent adjuster 38 on which in turn the protrusions 61a, b are formed to pressurize the cartridges. This structure is also used in the metering dispenser 10 of FIG. 5F, with the rotary and push button 104 being configured as actuator 40 and adjustment member 38 similar to FIG. 5A. In the associated plan view, the course of the pivot axis 43 is clearly visible.

In 6sind mehrere Ausführungen des Dreh-Druckknopfes 104 jeweils in Seitenansichten und in Schnittdarstellung gezeigt. Dabei ist oben die keilförmige Gestaltung (mit dem Rampenwinkel α an der Abstandsfläche 41 ersichtlich, ebenso darunter die wendelförmige Ausführung und in Art von treppenartigen Abstufungen. Von besonderer Bedeutung ist die unten dargestellte Einstelleinrichtung, die zwei gegenläufige Wendeln als Vorsprünge 61a, b aufweist, also die vorbeschriebenen Alternativen kombiniert. Dabei kann auch der eine Verdränger 26 vom äußeren Gewindegang (als Vorsprung 61a) und der andere Verdränger 26 der zweiten Pumpeinheit vom inneren Gewindegang (als Vorsprung 61b) beaufschlagt werden. Es können auch beide Pumpeinheiten 12a, b auf demselben Radius zur mittigen Hochachse H angeordnet sein. Somit können auch mehr als zwei Pumpeinheiten betätigt werden, indem die dritte und vierte Pumpeinheit vom innenliegenden Gewindegang bzw. Wendel betätigt werden. Das Mischungsverhältnis lässt sich somit gegenläufig durch einfaches Verdrehen um die Hochachse H einstellen.In Fig. 6, several embodiments of the rotary push button 104 are shown in side elevational and sectional views, respectively. In this case, the wedge-shaped configuration (with the ramp angle α at the spacer surface 41, as well as the helical design and in the form of staircase-like graduations) can be seen above The adjustment device shown below, which has two opposing helixes as projections 61a, b, is of particular importance In this case, the one displacer 26 from the outer thread (as a projection 61 a) and the other displacer 26 of the second pump unit from the inner thread (As a projection 61 b) are acted upon. It is also possible for both pumping units 12a, b to be arranged at the same radius to the central vertical axis H. Thus, more than two pumping units can be actuated by the third and fourth pump unit are actuated by the internal thread or helix. The mixing ratio can thus be set in opposite directions by simply rotating about the vertical axis H.
