Description
Zählvorrichtung für Brennstoffpumpen Die Erfindung betrifft Zählvorrichtungen für Brennstoffpumpen mit selbsttätiger Beendigung des Zapfvorganges bei der Rückkehr des Meßzeigers in die Nullage.Counting device for fuel pumps The invention relates to counting devices for fuel pumps with automatic termination of the dispensing process on return of the measuring pointer to the zero position.
Bei den bekannten Vorrichtungen dieser Art ist es denkbar, daß der Pumpvorgang unterbrochen, der Meßzeiger von Hand wieder ein Stück zurückgestellt und alsdann der Zapfvorgang fortgesetzt wird, ohne daß der Verkäufer den Betrug merkt.In the known devices of this type, it is conceivable that the The pumping process is interrupted, the pointer is set back a little by hand and then the dispensing process is continued without the seller fraudulent notices.
Derartige Betrugsmöglichkeiten sollen dadurch ausgeschlossen werden, daß gemäß der Erfindung der Meßzeiger mit einem durch den Zapfvorgang gesteuerten Lochkranz durch eine von Hand einstellbare und bei der Rückkehr des Meßzeigers in die Nullstellung sich selbstentsperrende Kupplung verbünden wird.Such opportunities for fraud are to be excluded, that according to the invention of the measuring pointer with a controlled by the dispensing process Perforated wreath by a manually adjustable and on return of the measuring pointer in the zero position will join the self-unlocking clutch.
In der Zeichnung ist eine beispielsweise Ausführungsform desErfindungsgegenstandes veranschaulicht, und zwar zeigt: Abb. r eine Ansicht, Abb. 2 einen Schnitt A-B, Abb. 3 und d. den Schnappstift der Kupplung.In the drawing is an exemplary embodiment of the subject matter of the invention illustrates, namely: Fig. r is a view, Fig. 2 is a section A-B, Fig. 3 and d. the snap pin of the coupling.
Bei einer Brennstoffentnahme mittels der in Rede stehenden Erfindung wird der von dem als Meßzeiger dienenden Hebel i gehaltene Schnappstift 2 durch Drehen des Hebels im Uhrzeigersinne in eine von den Bohrungen 3 des Schaltrades 8 der gewünschten Menge entsprechend geführt. Während dieses Einstellens- wird der Schleppzeiger ¢ mitgenommen und läßt durch seine Bohrung 5 die Brennstoffmengenangabe an einer festen Ziffernreihe 15 erkennen. Nun wird der Zapfhebel 6 betätigt, wodurch ein Anker 7 in das Schaltrad 8 eingreift und dieses in Drehung versetzt. Der den Stift 2 haltende Hebel r wird dabei mitgenommen und ein unbefugtes Herausziehen des Schnappstiftes 2 während dieses Vorganges dadurch unmöglich, daß der genannte Stift 2 einen Blatthaken 9 besitzt, der unter der Wirkung einer Feder i o hinter die Wandungen 16 der Bohrungen 3 faßt. Ist der Stift 2 infolge der Brennstoffentnahme und der dadurch bedingten Drehung des Schaltrades 8 in die Nurlstellung zurückgekommen, so hat der im Gehäuse i i befestigte und in den Lochkranz 17 ragende Anschlagstift 12 den genannten Blatthaken 9 des Schnappstiftes 2 zurückgedrückt (Abb. .4), so daß nunmehr ein Herausziehen des unter dem Druck einer Feder 13 stehenden Schnappstiftes 2 ermöglicht ist. Der Schleppzeiger .I befindet sich nun noch immer in der eingestellten Lage und zeigt den Verbrauch des Brennstoffes an. Er kann nunmehr leicht zurückgedreht werden. Ein Irrtum erscheint durch diese Anordnung ausgeschlossen.When fuel is withdrawn by means of the invention in question, the snap pin 2 held by the lever i serving as a measuring pointer is guided by turning the lever clockwise into one of the bores 3 of the ratchet 8 of the desired amount. During this setting, the drag pointer ¢ is taken along and, through its bore 5, shows the amount of fuel indicated by a fixed row of digits 15. Now the tap lever 6 is actuated, whereby an armature 7 engages in the ratchet wheel 8 and sets it in rotation. The lever r holding the pin 2 is taken along and an unauthorized pulling out of the snap pin 2 during this process is impossible because said pin 2 has a blade hook 9 which grips behind the walls 16 of the bores 3 under the action of a spring. If the pin 2 has returned to the normal position as a result of the removal of fuel and the resulting rotation of the ratchet wheel 8, the stop pin 12 fastened in the housing ii and protruding into the perforated ring 17 has pushed back the mentioned blade hook 9 of the snap pin 2 (Fig. 4), so that it is now possible to pull out the snap pin 2, which is under the pressure of a spring 13. The drag pointer .I is now still in the set position and shows the fuel consumption. It can now be turned back easily. An error appears to be excluded by this arrangement.
Der Zwischenraum zwischen zwei Bohrungen 3 entspricht einer Brennstoffmenge von beispielsweise 5 1. Eine Skala 15 erleichtert das Einstellen des Stell- und Schleppzeigers 2, q.. Durch die Betätigung des Ankers 7 wird gleichzeitig in bekannter Weise ein Summierzählwerk betrieben, das in einer Schauöffnung 1q. den Brennstoffverbrauch erkennen läßt. Die in der Zeichnung dargestellte Ausführungsform ist für eine Pumpe mit Zwillingsmeßgefäßen gedacht, mit der zwei verschiedene Brennstoffe gefördert werden können.The space between two holes 3 corresponds to an amount of fuel of, for example, 5 1. A scale 15 makes it easier to set the setting and drag pointer 2, q .. By actuating the armature 7, a totalizer is operated in a known manner at the same time, which is located in a viewing opening 1q . shows the fuel consumption. The embodiment shown in the drawing is intended for a pump with twin measuring vessels, with which two different fuels can be conveyed.
