In dem Gehäuse des Zapfventils ist wie üblich die Schaltautomatik für das Zapfventil aufgenommen. Zweckmäßigerweise ist der Gehäusestutzen bzw. die Gehäusestutzenwand fest und vorzugsweise einstückig an das Gehäuse bzw. an die Gehäusewand angeschlossen/angeformt. Es liegt im Rahmen der Erfindung dass die Rücklaufrinne des Rücklauftropfensammlers zum Dieselkraftstoff abgebenden Zapfrohrende hin offen ist. Es liegt fernerhin im Rahmen der Erfindung, dass die Rücklaufrinne über zumindest einen Teil des Umfangs des Zapfrohres umläuft und vorzugsweise über den gesamten Umfang des Zapfrohres umläuft.As usual, the switching mechanism for the nozzle is accommodated in the housing of the dispensing valve. Conveniently, the housing neck or the housing neck wall is fixed and preferably integrally connected to the housing or to the housing wall / molded. It is within the scope of the invention that the return trough of the return drop collector for diesel fuel dispensing Zapfrohrende is open. It is also in the frame the invention that the return trough rotates over at least part of the circumference of the dispensing tube and preferably rotates over the entire circumference of the dispensing tube.
Nach besonders bevorzugter Ausführungsform der Erfindung ist der Rücklauftropfensammler vollständig mit seiner Rücklaufrinne und seiner Aufnahmekammer in den Gehäusestutzen bzw. in das Gehäuse integriert. Gemäß dieser Ausführungsform ist der Rücklauftropfensammler also vollständig in dem Gehäusestutzen bzw. in dem Gehäuse aufgenommen. Dabei ist die Rücklaufrinne zweckmäßigerweise am Stirnende bzw. im Bereich des Stirnendes des Gehäusestutzens angeordnet. Stirnende des Gehäusestutzens meint hier das dem Dieselkraftstoff abgebenden Zapfrohrende zugewandte Ende des Gehäusestutzens.According to a particularly preferred embodiment of the invention, the return drop collector is completely integrated with its return channel and its receiving chamber in the housing neck or in the housing. According to this embodiment, the return drop collector is thus completely accommodated in the housing neck or in the housing. The return trough is expediently arranged at the front end or in the region of the front end of the housing neck. Front end of the housing stub here means the end of the housing nozzle facing the diesel fuel dispensing end facing.
Es empfiehlt sich, dass die zapfrohrseitige Innenseite der Gehäusestutzenwand im Bereich der Rücklaufrinne die Außenwand der Rücklaufrinne bildet. Nach besonders bevorzugter Ausführungsform besteht die Gehäusestutzenwand aus einem Metall, vorzugsweise aus Aluminium. Zweckmäßigerweise besteht auch die Gehäusewand des übrigen Gehäuses aus diesem Metall, bevorzugt aus Aluminium. Nach sehr empfohlener Ausführungsform besteht also die die Außenwand der Rücklaufrinne bildende Innenseite der Gehäusestutzenwand aus Metall bzw. aus Aluminium.It is recommended that the inside of the nozzle wall on the inside of the nozzle wall forms the outer wall of the return trough in the area of the return trough. According to a particularly preferred embodiment, the housing connecting wall is made of a metal, preferably of aluminum. Conveniently, the housing wall of the rest of the housing made of this metal, preferably made of aluminum. After highly recommended embodiment, so the forming the outer wall of the return channel inside the housing neck wall made of metal or aluminum.
Es empfiehlt sich weiterhin, dass die Außenoberfläche des Zapfrohres im Bereich der Rücklaufrinne die Innenwand der Rücklaufrinne bildet. - Die Rücklaufrinne dient erfindungsgemäß zum Auffangen der an der Außenoberfläche des Zapfrohres zurücklaufenden Dieselkraftstoffreste. Wie oben bereits dargelegt findet dieser Rücklauf insbesondere statt, wenn das Zapfventil mit dem Zapfrohr nach oben zur Zapfsäule zurückbewegt wird oder dort entsprechend aufgehängt wird.It is also recommended that the outer surface of the dispensing tube in the region of the return channel forms the inner wall of the return channel. - The return channel is used according to the invention for collecting the returning on the outer surface of the dispensing nozzle diesel fuel residues. As already explained above, this return takes place, in particular, when the dispensing valve with the dispensing tube is moved back up to the gas pump or is suspended there accordingly.
Es liegt im Rahmen der Erfindung, dass die Rücklaufrinne über zumindest zwei Drosselkanäle an die Aufnahmekammer des Rücklauftropfensammlers angeschlossen ist. Die Drosselkanäle sind zweckmäßigerweise ebenfalls in dem Gehäusestutzen bzw. in dem Gehäuse des Zapfventils aufgenommen. Es liegt im Rahmen der Erfindung, dass der Übergangsbereich zwischen Rücklaufrinne und Aufnahmekammer mit Ausnahme von den genannten Drosselkanälen geschlossen ausgebildet ist. Die Drosselkanäle können als drosselnde Ausnehmungen oder drosselnde Bohrungen ausgeführt sein. Der Lochquerschnitt des zumindest einen Drosselkanals beträgt vorzugsweise 1 bis 2 mm2. Vorzugsweise sind zwei Drosselkanäle vorgesehen. Dabei dient ein Drosselkanal dem Einlauf bzw. dem Auslauf des Dieselkraftstoffes in die bzw. aus der Aufnahmekammer und der zweite Drosselkanal ist für die jeweils ausströmende bzw. einströmende Luft vorgesehen (Entlüftungs- bzw. Belüftungskanal). Im Gegensatz zu dem bekannten eingangs behandelten Dieseltropfensammler sind erfindungsgemäß grundsätzlich zwei Drosselkanäle ausreichend. Bei dem bekannten Dieseltropfensammler war die vor dem Gehäusestutzen aufgesetzte Muffe verdrehbar und aus diesem Grunde mussten zwangsläufig mehrere Drosselkanäle vorgesehen werden um auch in verschiedenen Positionen die Funktion zu gewährleisten. Bei dem erfindungsgemäßen Rücklauftropfensammler können zwei Drosselkanäle an den optimalen Positionen ortsfest vorgesehen werden und weitere Drosselkanäle sind prinzipiell nicht erforderlich.It is within the scope of the invention that the return channel is connected via at least two throttle channels to the receiving chamber of the return drop collector. The throttle channels are expediently also received in the housing neck or in the housing of the dispensing valve. It is within the scope of the invention that the transition region between the return channel and the receiving chamber is designed to be closed except for the aforementioned throttle channels. The throttle channels can be designed as throttling recesses or throttling holes. The hole cross section of the at least one throttle channel is preferably 1 to 2 mm 2 . Preferably, two throttle channels are provided. In this case, a throttle duct serves the inlet or the outlet of the diesel fuel into and out of the receiving chamber and the second throttle channel is provided for the respective outflowing or inflowing air (venting or ventilation duct). In contrast to the known diesel drop collector initially treated, according to the invention basically two throttle channels are sufficient. In the case of the known diesel drop collector, the sleeve placed in front of the housing neck was rotatable and, for this reason, several throttle channels inevitably had to be provided in order to ensure the function even in different positions. In the return drop collector according to the invention, two throttle channels can be provided in a fixed position at the optimum positions, and further throttle channels are not required in principle.
Wenn das Zapfrohr nach oben gehalten wird bzw. das Zapfventil entsprechend eingehängt wird, läuft der an dem Zapfrohr zurücklaufende Dieselkraftstoff zunächst in die Rücklaufrinne und von dort über die Drosselkanäle langsam in die Aufnahmekammer des Rücklauftropfensammlers. Zwischen zwei Betankungsvorgängen verstreicht eine ausreichende Zeit, so dass der Dieselkraftstoffrest in dieser Zeit durch die Drosselkanäle langsam in die Aufnahmekammer gelangen kann. Wenn dann zu Beginn eines Betankungsvorgangs das Zapfrohr bzw. das Zapfventil gesenkt gehalten wird, benötigt der in der Aufnahmekammer aufgenommene Dieselkraftstoff zunächst einige Zeit um durch die Drosselkanäle zurück in die Rücklaufrinne zu gelangen. In dieser Zeit wird das Zapfventil in den Einfüllstutzen eines Kraftstofftankes eingeführt und der dann aus der Rücklaufrinne ablaufende Dieselkraftstoff kann an der Außenoberfläche des Zapfrohrs entlang in den Kraftstofftank gelangen. Bei einem üblichen Betankungsvorgang bleibt ausreichend Zeit für eine vollständige Entleerung der Aufnahmekammer. Auf diese Weise kann erfindungsgemäß ein Kontaminieren der Umgebung mit Dieselkraftstoffresten vermieden werden.If the dispensing tube is held upwards or the dispensing valve is suspended accordingly, the diesel fuel returning to the dispensing pipe first runs into the return funnel and from there via the throttle channels slowly into the receiving chamber of the return drop collector. A sufficient time elapses between two refueling operations, so that the diesel fuel residue can pass slowly through the throttle channels into the receiving chamber at this time. If then at the beginning of a refueling operation, the dispensing nozzle or the nozzle is kept lowered, which requires in the Recording chamber received diesel fuel first some time to get through the throttle channels back into the return channel. During this time, the nozzle is introduced into the filler neck of a fuel tank and then running out of the return channel diesel fuel can pass along the outer surface of the dispensing tube in the fuel tank. In a conventional refueling process, sufficient time remains for complete emptying of the receiving chamber. In this way, according to the invention, a contamination of the environment with diesel fuel residues can be avoided.
Es liegt im Rahmen der Erfindung, dass die Aufnahmekammer des Rücklauftropfensammlers über zumindest einen Teil des Umfangs des Zapfrohres bzw. des Gehäusestutzens umläuft. Vorzugsweise läuft die Aufnahmekammer über den gesamten Umfang des Zapfrohres bzw. des Gehäusestutzens um. Nach empfohlener Ausführungsform der Erfindung bildet die zapfrohrseitige Innenseite der Gehäusestutzenwand im Bereich der Aufnahmekammer die Außenwandung der Aufnahmekammer. Vorzugsweise besteht diese Gehäusestutzenwand aus Metall, besonders bevorzugt aus Aluminium. Es empfiehlt sich fernerhin, dass die Außenoberfläche des Zapfrohres im Bereich der Aufnahmekammer die Innenwandung der Aufnahmekammer bildet.It is within the scope of the invention that the receiving chamber of the return drop collector rotates over at least part of the circumference of the dispensing tube or the housing neck. Preferably, the receiving chamber overflows over the entire circumference of the dispensing tube or the housing neck. According to the recommended embodiment of the invention, the tap tube-side inside of the housing nozzle wall in the region of the receiving chamber forms the outer wall of the receiving chamber. Preferably, this housing connecting wall is made of metal, particularly preferably of aluminum. It is further recommended that the outer surface of the dispensing tube forms the inner wall of the receiving chamber in the region of the receiving chamber.
Nach der Erfindung ist der Gehäusestutzen und vorzugsweise das gesamte Gehäuse mit einem flexiblen Schutzüberzug überzogen. Bei dem flexiblen Schutzüberzug handelt es sich zweckmäßigerweise um einen Schutzüberzug aus Plastikmaterial bzw. Weichplastikmaterial (Weichplastikschutzüberzug). Gemäß der Erfindung besteht der Schutzüberzug aus einem Plastikmaterial und dieses Plastikmaterial ist mit der Maßgabe eingerichtet, dass es bei Einwirkung des Dieselkraftstoffes schrumpft und dadurch abdichtend wirkt. Vorzugsweise erfolgt die Schrumpfung des Plastikmaterials bzw. Weichplastikmaterials durch unter Einfluss des Dieselkraftstoffes stattfindenden Weichmacherverlust. Durch die Schrumpfung des Schutzüberzuges kann eine sehr effektive Abdichtung erzielt werden, sodass verhindert werden kann, dass Dieselkraftstoff zwischen Schutzüberzug und Gehäuse insbesondere durch Kapillarwirkung eindringen kann.According to the invention, the housing neck and preferably the entire housing is covered with a flexible protective cover. The flexible protective cover is expediently a protective cover of plastic material or soft plastic material (soft plastic protective cover). According to the invention, the protective cover is made of a plastic material and this plastic material is designed with the proviso that it shrinks under the action of the diesel fuel and thereby acts sealingly. Preferably, the shrinkage of the plastic material or soft plastic material takes place by taking place under the influence of the diesel fuel plasticizer loss. By the shrinkage of the protective coating, a very effective seal can be achieved, so that it can be prevented that diesel fuel between the protective cover and housing can penetrate in particular by capillary action.
Gemäß einer Ausführungsform der Erfindung ist der Gehäusestutzen im Bereich seines Stirnendes von einer über seinen Außenumfang umlaufenden Außenschutzkappe bzw. Außenschutzmanschette eingekapselt. Dabei verläuft diese Außenschutzkappe zweckmäßigerweise über den größten Teil der Länge des Gehäusestutzens. Die Außenschutzkappe kann in verschiedenen Farben ausgeführt werden und kann somit in vorteilhafter Weise zur farblichen Kennzeichnung eingesetzt werden. Bei erforderlichen Farbänderungen ist im Vergleich zu den eingangs beschriebenen bekannten Maßnahmen eine problemlose Umrüstung möglich, da die Außenschutzkappe einfach und ohne großen Aufwand auswechselbar ist.According to one embodiment of the invention, the housing stub is encapsulated in the region of its front end by an outer protective cap or outer protective cuff circulating over its outer circumference. In this case, this outer protective cap expediently extends over most of the length of the housing neck. The outer protective cap can be made in different colors and can thus be used advantageously for color coding. When required color changes a hassle-free conversion is possible in comparison to the known measures described above, since the outer cap is easy and replaceable without much effort.
Es liegt im Rahmen der Erfindung, dass zumindest eine zwischen Gehäusestutzen und Zapfrohr umlaufende Dichtung den übrigen Gehäuseinnenraum abdichtet. Hier kann eine ohnehin zwischen Gehäusestutzen und Zapfrohr erforderliche Dichtung zugleich der Abdichtung des Rücklauftropfensammlers gegen den übrigen Gehäuseinnenraum dienen. Eine bei dem bekannten Dieseltropfensammler erforderliche zusätzliche Dichtung zur Abdichtung der Aufnahmekammer gegen das Zapfrohr kann hier in vorteilhafter Weise entfallen.It is within the scope of the invention that at least one circumferential seal between the housing neck and dispensing tube seals the remaining housing interior. Here, a seal which is required in any case between the housing neck and the dispensing pipe can at the same time serve to seal the return drop collector against the remaining housing interior. An additional seal required for the known diesel drop collector for sealing the receiving chamber against the dispensing tube can be eliminated here in an advantageous manner.
Der Erfindung liegt die Erkenntnis zugrunde, dass sich bei dem erfindungsgemäßen Zapfventil beachtliche wirtschaftliche Vorteile mit wesentlichen umwelttechnischen Vorteilen kombinieren lassen. Zunächst werden zur Verwirklichung des erfindungsgemäßen Rücklauftropfensammlers im Wesentlichen bereits am Zapfventil ohnehin vorhandene Bauelemente verwendet. Im Vergleich zu dem eingangs erläuterten Stand der Technik entfällt ein zusätzliches aufwendiges Bauelement, das im Hinblick auf den Stückpreis des Zapfventils Mehrkosten verursacht. Insbesondere kann im Vergleich zum Stand der Technik auch auf einen O-Dichtungsring verzichtet werden sowie die damit verbundenen Herstellungs-, Bearbeitungs- und Montagekosten. Im Ergebnis ist auch der Zusammenbau bzw. die Montage eines erfindungsgemäßen Zapfventils weniger aufwendig als die Montage des eingangs erläuterten Zapfventils nach dem Stand der Technik. An den erfindungsgemäßen Zapfventilen können im Übrigen Schutzüberzüge, insbesondere Weichplastikschutzüberzüge problemlos gewechselt werden, ohne dass der Rücklauftropfensammler hierbei hinderlich ist. Fernerhin ist der erfindungsgemäße Rücklauftropfensammler geschützt gegenüber äußeren mechanischen Beanspruchungen aufgenommen und zeichnet sich somit durch eine lange Lebensdauer bzw. eine sehr langfristige Funktionssicherheit aus. Auch Beschädigungen von Komponenten des zu befüllenden Kraftstofftanks durch den Rücklauftropfensammler können vollständig vermieden werden. Weiterhin werden rücklaufende Dieselkraftstoffreste funktionssicher von dem erfindungsgemäßen Rücklauftropfensammler aufgefangen und eine Kontamination der Umgebung kann effektiv vermieden werden. Die erfindungsgemäße integrierte Ausgestaltung des Rücklauftropfensammlers erlaubt ein relativ großes Volumen der Aufnahmekammer, sodass ein nachteilhafter Überlauf effektiv vermieden werden kann. Das Volumen der Aufnahmekammer kann mindestens das Vierfache des entsprechenden Volumens bei dem bekannten Dieseltropfensammler betragen. Auch darin ist ein wesentlicher Vorteil der Erfindung zu sehen. Aufgrund der sehr beachtlichen Vorteile des erfindungsgemäßen Zapfventils dürfte zukünftig die Entscheidung zu Gunsten dieses Zapfventils fallen, so dass dadurch ein erheblicher umwelttechnischer Vorteil erreicht wird, weil es keine Rechtfertigung mehr dafür gibt, Zapfventile ohne den erfindungsgemäßen Rücklauftropfensammler einzusetzen.The invention is based on the finding that considerable economic advantages can be combined with significant environmental advantages in the dispensing valve according to the invention. First of all, components already present at the dispensing valve are used to implement the return drop collector according to the invention. in the Compared to the prior art explained at the outset, an additional complex component which causes additional costs with regard to the unit price of the dispensing valve is dispensed with. In particular, in comparison to the prior art can be dispensed with an O-ring seal and the associated manufacturing, processing and assembly costs. As a result, the assembly or assembly of a dispensing valve according to the invention is less expensive than the assembly of the initially described dispensing valve according to the prior art. By the way, protective coatings, in particular soft plastic protective coatings, can easily be exchanged at the dispensing valves according to the invention without the return drop collector being a hindrance here. Furthermore, the return drop collector according to the invention is protected against external mechanical stresses added and is thus characterized by a long life and a very long-term reliability. Damage to components of the fuel tank to be filled by the return drop collector can be completely avoided. Furthermore, returning diesel fuel residues are reliably absorbed by the return drop collector according to the invention and contamination of the environment can be effectively avoided. The inventive integrated design of the return drop collector allows a relatively large volume of the receiving chamber, so that a disadvantageous overflow can be effectively avoided. The volume of the receiving chamber may be at least four times the corresponding volume in the known diesel drop collector. Again, a significant advantage of the invention is to be seen. Due to the very considerable advantages of the dispensing valve according to the invention, the decision will fall in favor of this dispensing valve in the future, so that a significant environmental advantage is achieved because there is no justification to use dispensing valves without the return drop collector according to the invention.
