Description

  • Die Erfindung betrifft eine Austragvorrichtung für Medien nach dem Oberbegriff des Patentanspruches 1. The invention relates to a discharge device for media according to the preamble of claim 1.
  • Besonders pharmazeutische und kosmetische, aber auch technische und ähnliche Medien, können im Anwendungszustand aus Zwei oder mehr Komponenten bestehen, die aus Gründen einer einzuhaltenden Reaktionszeit, einer möglichst frischen und daher wirksamen Zubereitung oder weil sie im gemischten Zustand zu Veränderungen, beispielsweise geringerer Haltbarkeit, neigen, möglichst erst kurz vor Gebrauch bzw. beim Gebrauch gemischt werden sollten. Particularly pharmaceutical and cosmetic, but also technical and similar media, can the application state of two or more components are made on grounds any time limit response time, a fresh as possible and therefore effective preparation or because they tend in the mixed state to change, even in lower durability, should be possible mixed just before use or in use. Daher werden solche Mischmedien in der Regel getrennt voneinander in gesonderten Gefäßen bereitgestellt. Therefore, such a mixed media are generally provided separately from each other in separate vessels. Entweder müssen die Komponenten vor dem Gebrauch gemischt oder bei pharmazeutischen und kosmetischen Zubereitungen gelegentlich unmittelbar nacheinander appliziert und da-durch zur Verbindung bzw. Mischung gebracht werden. Either the components must be mixed before use or applied in pharmaceutical and cosmetic formulations sometimes immediately after the other and there-by are brought to the compound or mixture. Hierzu bedarf es einiger Geschicklichkeit und auch hoher Sorgfalt, wenn es darauf ankommt, daß die Komponenten in einem genauen Mengenverhältnis miteinander anzuwenden sind. This requires some skill and great care when it comes down to it that the components are to be applied together in a precise ratio.
  • Durch die US-A-3 760 986 ist eine Austragvorrichtung gemäß dem Oberbegriff des Anspruchs 1 mit zwei nebeneinanderstehend am Speicher befestigten Austragpumpen bekanntgeworden. Through the US-A-3,760,986 a discharge has become known according to the preamble of claim 1 with two standing side by side attached to the memory discharge pumps. Sowohl die Pumpengehäuse einerseits als auch die Wandungen gesonderter Speicherräume des Speichers andererseits sind jeweils einteilig miteinander ausgebildet, wobei die Pumpengehäuse mit einer einzigen Schraubkappe am Hals des Speichers befestigt sind. Both the pump housing on the one hand and the walls separate memory spaces of the memory on the other hand are each formed integral with each other, wherein the pump housing are fixed with a single screw cap on the neck of the memory. Dadurch kann der jeweilige Einzelspeicher nicht unabhängig vom anderen abgenommen bzw. ausgewechselt werden. Thereby, the respective individual memory can not be removed from the other or replaced independently.
  • Die US-A-3 303 970 zeigt demgegenüber gesonderte, an einem Träger angeordnete Speicher, aus denen jedoch nicht mit Pumpen, sondern lediglich durch Öffnen von Auslaßventilen gefördert wird, da es sich um Behälter mit einer Treibgasfüllung handelt. The US-A-3,303,970 shows, in contrast separate, arranged on a support memory, but from which not promoted with pumps, but merely by opening of exhaust valves, since it is the container with a propellant filling. Die Speicher müssen hier bereits bei der Herstellung mit dem, einen Betätigungsmechanismus aufweisenden, Träger verbunden werden, da nach dem Zusammenbau aller Bauteile der Austragvorrichtung weder ein Einsetzen noch ein Entnehmen oder Auswechseln des jeweiligen Speichers mehr möglich ist. The memory must having already during the production to the, an actuating mechanism, carriers are connected, as after assembly of all components of the dispensing neither insertion nor a removal or replacement of the respective memory is no longer possible here.
  • Der Erfindung liegt die Aufgabe zugrunde, eine Austragvorrichtung der genannten Art zu schaffen, mit welcher mindestens zwei in Verbindung miteinander anzuwendende Komponenten zeitlich aufeinander genau abgestimmt ausgebracht und durch einfache Handbetätigung in Verbindung miteinander gebracht werden können, ohne daß die Medien hierzu im Speicher einem Druck ausgesetzt werden müssen. The invention has for its object to provide a discharge device of the type mentioned, with which at least two applicable interconnected components successive manure timed precisely tailored and can be brought together by simple manual operation in connection, without the media to this suspended in memory a pressure Need to become. Ferner sollen die Speicher unabhängig voneinander angebracht bzw. ausgewechselt werden können. Further, the memory should be able to be installed or replaced independently.
  • Diese Aufgabe wird durch die Austragvorrichtung nach Patentanspruch 1 gelöst. This object is achieved by the dispensing device according to Claim. 1 Jeder Speicher kann unabhängig vom anderen jederzeit mit der Austragvorrichtung verbunden, von ihr abgenommen oder ausgewechselt werden, je nachdem, welche Erfordernisse an die Austragvorrichtung gestellt werden. Each memory can independently of the other at any time with the discharge device connected to be removed or replaced by it, depending on what requirements are imposed on the discharge device. Die Komponenten werden einerseits in ihren noch nicht verwendeten gespeicherten Vorratsmengen ständig getrennt voneinander gehalten und andererseits können die beiden Komponenten durch Betätigung nur einer einzigen Handhabe in einem relativ genau bestimmbaren Mengenverhältnis in Verbindung miteinander gebracht bzw. ausgetragen werden. The components are on the one hand constantly held in their unused stored supply quantities separately from one another and on the other hand, the two components can be placed on a single handle in a relatively accurately determinable amount ratio in conjunction with each other and discharged by operation. Austragpumpen der genannten Art können nämlich als verhältnismäßig genau dosierende Dosierpumpen ausgebildet sein, die mit jedem Pumptakt eine genau reproduzierbare Menge an Medium fördern, wobei die gemeinsam zu betätigenden Austragpumpen je nach den Erfordernissen gleiche oder unterschiedliche Fördermengen aufweisen können. Discharge pumps of the above type may be formed as a relatively namely exactly metered dosing pumps which promote accurately reproducible amount of medium with each pumping stroke, the same flow rates jointly operable discharge pumps according to the requirements or different may have.
  • Es ist denkbar, die Anordnung so vorzusehen, daß die Austragpumpen nach Art einer Registersteuerung unmittelbar aufeinander folgend, also nacheinander in Stufen fördern, so daß die zugehörigen Komponenten nacheinander ausgetragen werden. It is conceivable to provide the arrangement so that the discharge pumps in the manner of a register control in immediate succession, so promote successively in stages so that the respective components are sequentially discharged. Besonders vorteilhaft ist es jedoch, wenn die Ausbildung so vorgesehen ist, daß bei Betätigung der Handhabe mindestens zwei von dieser betätigbare Austragpumpen gleichzeitig bzw. simultan fördern, so daß die Komponenten unmittelbar beim Austragen miteinander gemischt werden können. It is particularly advantageous, it is, however, the configuration is so provided that at least two and simultaneously promote simultaneously with actuation of the handle of this actuatable discharge pumps, so that the components during discharge can be mixed with each other directly. Hierzu führen die Auslaßkanäle mindestens zweier Austragpumpen zweckmäßig zu einer Komponenten-Mischzone, die vorzugsweise in unmittelbarer Nähe wenigstens einer Auslaßöffnung liegt. For this purpose, the outlet channels lead at least two discharge pumps expedient to a component mixing zone, which preferably is located close to at least one outlet opening.
  • Ist mindestens eine Komponente von der Art, daß ihr eine unmittelbare Berührung mit Luft vor Vermischung mit der anderen Komponente abträglich ist, so ist die Mischzone vorteilhaft in Austragrichtung vor der Auslaßöffnung, insbesondere unmittelbar benachbart zum Eintritt in eine Auslaßdüse vorgesehen, wobei vorzugsweise beide Auslaßkanäle in einen gemeinsamen Endkanal übergehen, der seinerseits in die beispielsweise am Umfang und/oder im Bereich ihrer hinteren Stirnseite mit schraubenwendelförmigen oder spiralnutartigen Drallkanälen versehene Auslaßdüse mündet. Is at least one component of the type that its direct contact with air prior to blending with the other component is detrimental, the mixing zone is advantageously in the discharge direction before the outlet aperture, in particular provided immediately adjacent to the entry in a discharge nozzle, wherein preferably both outlet channels in pass over a common end channel, which in turn opens into the provided, for example, on the circumference and / or in the region of its rear end side with coil-shaped or spiralnutartigen outlet nozzle swirl channels. Dadurch sind ab etwa dem Bereich, in welchem die Komponenten zusammengebracht werden und vor der Auslaßöffnung Wirbelzonen bzw. Wirbelkammern gebildet, in welchen die zusammengebrachten Komponenten intensiv unter Ausnutzung des Förderdruckes vermischt werden. Thereby, from about the region in which the components are brought together and formed in front of the outlet zones of turbulence or vortex chambers in which the matched components are intensively mixed by utilizing the delivery pressure.
  • Nicht nur bei aufeinanderfolgendem Austrag der Komponenten, sondern auch bei gleichzeitigem Austrag kann es aber auch aufgrund spezifischer Eigenschaften dieser Komponenten vorteilhaft sein, wenn die Komponenten erst außerhalb der Austragvorrichtung zusammengebracht werden, so daß das Verbleiben vermischter Komponenten in der Austragvorrichtung völlig ausgeschlossen ist. but not only in successive discharge of the components, but also with simultaneous discharge, it may be advantageous due to specific properties of these components when the components are brought together only outside the discharge so that the remaining mixed components is completely excluded in the discharge device. In diesem Fall liegt die Mischzone in Austragrichtung nach der Auslaßöffnung, insbesondere außerhalb der Austragvorrichtung im Freien. In this case, the mixing zone is located in the discharge of the outlet opening, in particular outside the discharge outdoors. Je nach Eigenart des Mediums kann es dabei zweckmäßig sein, daß die austretenden Komponenten an benachbarten Stellen gesondert aufgetragen und dann beispielsweise durch Verreiben miteinander vermischt werden. Depending on the nature of the medium, it may be advantageous here that the exiting components applied separately on adjacent sites and are then mixed together, for example by trituration. Die Komponenten können aber auch in diesem Fall vor Erreichen der Auftragstelle außerhalb der Austragvorrichtung sehr gut gemischt werden, da handbetätigbare Pumpen bei Verwendung entsprechend gestalteter Auslaßdüsen besonders vorteilhaft zur Erzeugung eines feinsten Sprühnebel-Strahles geeignet sind. However, the components can in this case before reaching the point of application outside of the discharge are mixed very well as hand-operated pumps using correspondingly designed outlet nozzles particularly advantageous to produce a fine spray jet are suitable. Sind die Auslaßöffnungen so zueinander ausgerichtet, daß sich die aus ihnen austretenden Strahle in nicht allzu weiter Entfernung von den Auslaßdüsen überschneiden, so ist insbesondere bei Erzeugung von Sprühnebel-Strahlen infolge der feinsten Tröpfchenverteilung des Mediums in dieser durch Überschneidung gebildeten Sprühnebelzone eine sehr intensive Durchmischung in äußerst kurzem zeitlichem Abstand vor dem Auftreffen auf der Auftragstelle zu erzielen. If the outlet openings aligned with each other so that the emerging from them beams overlap in the not too far away from the outlet nozzles, thus the medium in the formed by overlapping spray zone is particularly important in the production of spray-rays due to the fine droplet distribution, a very intensive mixing in to achieve extremely short interval before striking the application site. Dies kann in besonderem Maße bei pharmazeutischen Wirkstoffen von großem Vorteil sein, da diese häufig eine umso bessere Wirksamkeit haben, je frischer sie vor der Anwendung angemischt sind. This may be in active pharmaceutical ingredients is of great advantage especially true because they have an even better efficacy often, the fresher they are mixed prior to application.
  • Zur Erzielung einer möglichst kompakten und leicht handzuhabenden Bauweise ist die Austragöffnung bzw. sind die Austragöffnungen unmittelbar an der Handhabe vorgesehen, wobei sie etwa bündig in einer Wandung der Handhabe liegen oder am Ende eines über den Außenumfang der Handhabe vorstehenden Ansatzes, wie eines Schnabels, vorgesehen sein können. To achieve a compact as possible and easy to handle construction is the discharge opening or the discharge openings are provided directly on the handle, being about lie flush in a wall of the handle or at the end of a projecting beyond the outer periphery of the handle approach as a beak, provided could be.
  • Es ist vorteilhaft, wenn zur Erzielung einer möglichst großen Stabilität der Gesamtvorrichtung die Handhabe mindestens zwei nebeneinanderliegende Austragpumpen miteinander, insbesondere nach Art einer Brücke, verbindet und vorzugsweise einteilig ausgebildet ist. It is advantageous if in order to achieve the greatest possible stability of the overall apparatus, the handle to one another, particularly in the manner of a bridge connecting at least two adjacent discharge pumps and is preferably formed in one piece. Dies wird noch weiter verbessert, wenn die Handhabe im Bereich der Brükke liegt, die eine gemeinsame brückenartige Anschlußkappe für die insbesondere flaschenförmigen Speicher bildet, wobei die Handhabe vorzugsweise mit einem Wandungsrand in einen ihrer Grundform entsprechenden Ringsteg der Brücke eingreift, so daß die beiden gesonderten, flaschenförmigen und ggf. gleichen Speicher nicht unmittelbar in Berührung oder mechanisch fester Verbindung miteinander stehen müssen, sondern mit geringem Abstand auf Lücke benachbart zueinander angeordnet werden können. This is even further improved when the handle is in the range of Brükke which forms a common bridge-like connecting cap for the particular bottle-shaped memory, said handle preferably having a wall periphery in a basic form respective annular web of the bridge engages, so that the separate two, bottle-shaped and, if necessary, the same memory does not have to be in direct contact with or mechanically fixed connection with each other but at a small distance to adjacent gap can be arranged to each other.
  • In weiterer Ausgestaltung der Erfindung weist die Brücke bzw. die Anschlußkappe als gesonderte Schraubverbindungen für die Austragpumpen ggf. gesonderte Verbindungskappen für Flaschenhälse der etwa parallel unmittelbar benachbart zueinanderstehenden Speicher auf, wobei auch die Brücke bzw. die Anschlußkappe einteilig ausgebildet sein kann. In a further embodiment of the invention, the bridge or the connector cap as separate bolted connections for the discharge pumps to possibly separate connection caps for bottles necks of the approximately parallel immediately adjacent to one another memory, the bridge and the terminal cap can be integrally formed. Flaschenhälse von Speichern können auch durch einfache, druckdichte Schnappverbindungen gesondert oder gemeinsam in Eingriff mit den Verbindungskappen gebracht werden, was insbesondere vorteilhaft ist, wenn die zugehörigen Speicher durch einen formfesten Bauteil gebildet sind. Bottle necks of memories may also be separately through simple, pressure-tight snap connections or jointly brought into engagement with the connection caps, which is particularly advantageous if the associated memory are formed by a dimensionally stable component. Die gesondert ausgebildeten Speicher werden mit ihren Flaschenhälsen über Gewinde in Eingriff mit den Verbindungskappen gebracht und unabhängig voneinander in die Verbindungskappen eingeschraubt. The separately formed storage are brought with their bottle necks threadedly engaged with the connecting cap and screwed independently of one another in the connection caps.
  • Zur weiteren Erhöhung der Festigkeit der Gesamtvorrichtung und zur Vermeidung von eventuell zu Lecks führenden Belastungen der Verbindung der Austragvorrichtung mit den Speichern, kann nach der Herstellung dieser Verbindung eine zusätzliche Halterungsbrücke an den Speichern angebracht werden, die vorzugsweise durch eine flache, die Speicher im Bodenbereich eng umschließende Steckkappe gebildet ist. To further increase the strength of the overall apparatus and to prevent possibly resulting in leaks charges of the compound of the discharge device with the memories, an additional holding bridge can be attached to the memories after the preparation of this compound, which is preferably closely by a flat, the memory in the bottom area encircling plug cap is formed.
  • Die erfindungsgemäße Ausbildung ist insbesondere für solche Austragvorrichtungen geeignet, bei denen die Austragpumpen nicht als Balg-, elastische Kammer- oder ähnliche Pumpen, sondern als Schubkolbenpumpen ausgebildet sind, da diese wesentliche Vorteile haben. Training invention is particularly suitable for such dispensing devices in which the discharge pumps are not designed as a bellows, elastic chamber or similar pumps but as a thrust piston pump, as they have significant advantages. Sie können mit hohen Förderdrücken betrieben werden, eignen sich zur sehr genauen Dosierung, erlauben einen luftdichten Abschluß sowohl des Pumpengehäuses als auch des Speichers bei Ausgangsstellung der Pumpe, gewährleisten eine hohe Austraggeschwindigkeit und sind sowohl zum tropfenweisen als auch zum spritzstrahlartigen oder sprühstrahlartigen Austrag geeignet; They can be operated at high delivery pressures are suitable for very accurate dosage, allowing an airtight seal both of the pump housing as well as the memory at the starting position of the pump, ensuring a high discharge rate and are very convenient for dropwise as suitable for injection jet-like or sprühstrahlartigen discharge; ferner können sie sowohl für flüssige wie auch für pastöse bzw. breiige oder ähnlich fließfähige Medien verwendet werden. Further, they can both liquid as well as pasty or pulpy or similar flowable media may be used. Zweckmäßig weist die jeweilige Austragpumpe ein vom Druck in der Pumpenkammer oder in Abhängigkeit von der Kolbenstellung des Pumpkolbens gesteuertes Auslaßventil auf, das somit die Verbindung von der Pumpenkammer zum Auslaßkanal erst öffnet, wenn in der Pumpenkammer bei geschlossenem Zustand eines die Verbindung zum Speicher herstellenden Saugventiles ein verhältnismäßig hoher Druck aufgebaut ist. Suitably, the respective discharge pump a controlled by the pressure in the pump chamber or in dependence on the piston position of the pump piston outlet valve, which thus opens the connection from the pump chamber to the outlet passage only when a connection to the memory manufacturing in the pump chamber when closed suction valve, a relatively high pressure is built up.

  • Wie die Fig. 1 bis 4 zeigen, weist eine erfindungsgemäße Austragvorrichtung 1 zwei fläschchenförmige, im wesentlichen zylindrische Speicher 2 zur Vorratshaltung von Medien-Komponenten auf, in die jeweils eine Austragpumpe 3 im Bereich des Flaschenhalses 4 eingesetzt ist. As shown in FIGS. 1 to 4 show, includes a discharge device according to the invention 1, two vials shaped, substantially cylindrical storage tank 2 for stockpiling of media components, in each of which a discharge pump 3 is inserted in the region of the bottle neck 4. Die beiden Flaschenhälse 4 sind über eine in Draufsicht langrunde Anschlußkappe 5 derart formschlüssig miteinander verbunden, daß die beiden Speicher 2 mit geringem Abstand voneinander parallel zueinander sowie in gleicher Höhe vorgesehen sind. The two bottle necks 4 are interconnected by a long round in plan view connecting cap 5 in such a form-fitting manner with each other, that the two memories are provided and 2 from each other, parallel to each other at a small distance in the same amount. Im Bereich jedes etwa halbrunden Endes bildet die Anschlußkappe 5 an der Innenseite eine im wesentlichen achssymmetrische Verbindungskappe 6, welche im Bereich des halbrunden Endes mit der Anschlußkappe 5 eine gemeinsame Wandung bildet und gleiche Höhe wie die Anschlußkappe 5 hat. In the region of each approximately semi-circular end of the terminal cap 5 on the inner side forms a substantially axisymmetric connecting cap 6, which forms a common wall in the region of the semi-circular end to the connecting cap 5 and same height as the terminal cap 5 has. Die Verbindungskappen 6 übergreifen die beiden Flaschenhälse 4 und sind über Schraub-Gewindeverbindungen 8 auf den Flaschenhälsen 4 festgezogen. The compound caps 6 engage over the two bottle necks 4, and are tightened by screw-threaded connections 8 on the bottle necks. 4 Jede Verbindungskappe 6 bildet eine Halterung 7 für die zugehörige Austragpumpe 3 in Form einer einen Ringflansch des Pumpengehäuses aufnehmenden Ringschulter, welche diesen Ringflansch 11 unter Zwischenlage einer Ringdichtung 9 gegen die äußere Stirnfläche des zugehörigen Flaschenhalses 4 spannt. Each connecting cap 6 forms a support 7 for the associated discharge pump 3 in the form of an annular flange of the pump casing receiving ring shoulder which biases this annular flange 11 with the interposition of a ring seal 9 against the outer end face of the associated bottle neck. 4
  • Beide Austragpumpen 3 sind mit einer gemeinsamen Handhabe 10 in Form einer achsparallel zu den Austragpumpen 3 verschiebbaren Betätigungskappe verbunden, die im wesentlichen gleiche Grundform wie die Anschlußkappe 5 aufweist, jedoch gegenüber dieser in Draufsicht geringfügig kleiner ist. Both discharge pumps 3 are connected with a common handle 10 in the form of an axially displaceable to discharge pumps 3 actuator cap, in substantially the same basic shape as the connecting cap 5 has, but opposite this in a plan view is slightly smaller. Die Handhabe 10 greift mit ihrem den Speichern 2 zugekehrten, langrunden Wandungsrand 13 in die Innenseite eines sie mit geringem Spaltabstand umgebenden Ringsteges 12 ein, der über die äußere Stirnseite der die Stirnwandungen der Verbindungskappen 6 bildenden Stirnwand der Anschlußkappe 5 vorsteht. The handle 10 engages with its memories 2 facing long round wall periphery 13 in the inside of a surrounding with a small gap distance annular rib 12 projecting a, of forming on the outer end face of the end walls of the connection caps 6 end wall of the terminal cap. 5 In der den Wandungsrand 13 bildenden Umfangswand der Handhabe 10 ist benachbart zu deren zur Betätigung zu drückenden Stirnwand eine Auslaßöffnung 16 vorgesehen, die über Auslaßkanäle 14 der beiden Austragpumpen 3 und an diese anschließende Austrittskanäle 15 in der Handhabe 10 an die beiden Pumpenkammern beider Austragpumpen 3 angeschlossen ist. In the wall periphery 13 forming the peripheral wall of the handle 10 is adjacent to provided which for operating to press the end wall an outlet opening 16, which connected via outlet channels 14 of the two discharge pumps 3 and adjacent thereto exit channels 15 in the handle 10 to the two pumping chambers of both discharge pumps 3 is. Die beiden Austragpumpen 3 ihrerseits sind jeweils durch einen durch ein Steigrohr gebildeten Saugkanal 17 saugseitig in Bodennähe an den zugehörigen Speicher 2 angeschlossen. The two discharge pumps 3 in turn are each connected by a suction channel formed by a riser pipe 17 the suction side near the bottom of the associated memory. 2 Durch Niederdrücken der Handhabe 10 entgegen der Kraft von Rückstellfedern der beiden Austragpumpen 3 wird aus beiden Speichern 2 gleichzeitig Medium in Richtung zur Auslaßöffnung 16 gefördert und vor Erreichen der Auslaßöffnung 16 durch ggf. verwirbeltes Zusammenführen mit der jeweils anderen Komponente gemischt, wonach das so hergestellte Mischmedium als ein einziger, ggf. versprühter Strahl aus der Austrittsöffnung 16 austritt. By depressing the handle 10 against the force of return springs of the two discharge pumps 3 medium from both memories 2 conveyed in the direction to the outlet opening 16 and mixed before reaching the outlet port 16 by possibly intermingled merging with the other component at the same time, after which the mixing medium thus prepared emerges as a single, possibly atomized jet from the outlet opening sixteenth Es ist aber auch denkbar, die beiden Komponenten über gesonderte, unmittelbar benachbart zueinander beispielsweise in konzentrischen Kränzen liegende Düsenöffnungen auszutragen und dadurch bereits im Bereich des Austrittes zusammenzubringen; However, it is also conceivable for the two components of separate, immediately adjacent each other, for example, discharge in concentric rings lying nozzle openings and thereby bring together already in the region of the outlet; die Düsenöffnungen können dann in einem gemeinsamen Düsenkörper vorgesehen sein. the nozzle openings can then be provided in a common nozzle body. Im dargestellten Ausführungsbeispiel sind die beiden achsgleich zueinanderliegenden Austrittskanäle 15 bis zur Anschlußstelle an einen Endkanal 18 gegeneinander gerichtet bzw. durch einen einzigen durchgehenden Kanal gebildet, an welchen der zur Auslaßöffnung 16 führende Endkanal 18 rechtwinklig angeschlossen ist; In the illustrated embodiment, the two coaxial to each other lying outlet channels 15 to the connection point addressed to a terminal duct 18 against each other and formed by a single continuous channel, which is at the leading end channel to the outlet opening 16 connected at right angles 18; im Bereich dieses Anschlußes ist die Anordnung einer im Querschnitt ggf. erweiterten Wirbelkammer denkbar. in the region of this connection, the arrangement of an optionally cross-sectionally extended swirl chamber is also conceivable.
  • Die beiden Austrittskanäle 15 sind zweckmäßig gleich lang, so daß beide Komponenten etwa gleichen Strömungsverhältnissen ausgesetzt sind. The two outlet channels 15 are suitably the same length, so that both components are exposed to approximately the same flow conditions. Die gemäß Fig. 2 am Ende eines frei vorstehenden Schnabels 19 vorgesehene Auslaßöffnung 16 liegt an einer langen Seite der Handhabe 10 und zwar in der Mitte dieser langen Seite. The FIG. 2 at the end of a freely projecting beak 19 provided for outlet port 16 is located on a long side of the handle 10 and that in the middle of this long side.
  • Jede Austragpumpe 3 ist als Schubkolbenpumpe ausgebildet, deren durch den Flaschenhals 4 in den zugehörigen Speicher 2 ragendes, zum Saugkanal 17 im Außendurchmesser mehrfach abgesetzt reduziertes Zylindergehäuse 20 über seine gesamte Länge mit Abstand vom Innenumfang des Flaschenhalses 4 liegt. Each discharge pump 3 is constructed as a thrust piston pump, whose projecting through the neck 4 into the associated memory 2, 17 more times discontinued reduced in outside diameter cylinder housing 20 is located on the suction channel along its entire length at a distance from the inner periphery of the bottle neck. 4 Die Austragpumpe 3 weist eine im Zylindergehäuse 20 verschiebbare Kolbeneinheit 21 mit einer elastischen Kolbenmanschette 22 auf, die an ihrem äußeren Ende einteilig mit einer elastisch federnden Stauchhülse 23 ausgebildet ist. The discharge pump 3 has a slidable piston 20 in the cylinder housing unit 21 having a resilient piston sleeve 22, which is formed at its outer end in one piece with an elastically resilient compression sleeve 23rd Die Kolbenmanschette 22 und die Stauchhülse 23 sind am Außenumfang eines Kolbenstößels 24 angeordnet, welcher aus dem Pumpengehäuse und über den Ringsteg 12 in die Handhabe 10 vorsteht und von dem Auslaßkanal 14 durchsetzt ist. The piston sleeve 22 and the compression sleeve 23 are arranged on the outer periphery of a piston ram 24 which projects from the pump housing and the annular web 12 in the handle 10 and is traversed by the outlet channel fourteenth Die Kolbenmanschette 22 bildet im Übergangsbereich zur Stauchhülse 23 den äußeren, ringförmigen Ventilschließteil eines im einzelnen nicht näher dargestellten Auslaßventiles 25, dessen Ventilsitz am Kolbenstößel 24 vorgesehen ist.
