Abstract

A petrol pump assembly for retail use consists of the forecourt unit with hose and trigger-operated fuel dispenser nozzle. The hose is connected on one side to the pump and on the other to the nozzle unit. The link is effected by a co-axial universal union incorporating a cam-operated shut-off valve.

Description

Der Stecker (1) wird über die Überwurfmutter (2) mit dem Kupplungsteil (3) verbunden. Gleichzeitig wird beim Kuppelvorgang über den Entriegelungsbolzen (4) die Verrigelung (5) zurückgeschoben und dadurch die Nockenwelle (6) für eine Drehbewegung freigegeben. Sind die beiden Kupplunghälften verschraubt, wird der Hebel (7) um 65° bis zum Anschlag gedreht. An der Endposition rastet ein Gewindedruckstück (8) ein und verhindert somit ein Zurückschnappen des Hebels. Beim Schwenkvorgang des Hebels (7) dreht sich die Nockenwelle (6) mit. Über die Nocken (9) werden die Schließbolzen (10), bzw. die Schließringe (11) jeweils um 7,5 mm zurückgedrückt. Dadurch werden die Überströmkanäle innen (12) für die Kraftstoffzuführung und außen (13) für die Gasrückführung freigegeben.The connector ( 1 ) is connected to the coupling part ( 3 ) via the union nut ( 2 ). At the same time, during the coupling process, the locking mechanism ( 5 ) is pushed back over the unlocking bolt ( 4 ), thereby releasing the camshaft ( 6 ) for a rotary movement. If the two coupling halves are screwed together, the lever ( 7 ) is turned by 65 ° as far as it will go. A threaded pressure piece ( 8 ) engages at the end position and thus prevents the lever from snapping back. When the lever ( 7 ) swivels, the camshaft ( 6 ) rotates with it. The locking bolts ( 10 ) or the locking rings ( 11 ) are each pushed back by 7.5 mm via the cams ( 9 ). As a result, the overflow channels inside ( 12 ) for the fuel supply and outside ( 13 ) for the gas return are released.

Der Kraftstoff fließt nun über den ersten inneren Überströmkanal (12) am Schließbolzen (10), an der Nockenwelle (6) und über den zweiten Überströmkanal (12) am zweiten Schließbolzen (10) vorbei.The fuel now flows via the first internal overflow channel ( 12 ) past the locking pin ( 10 ), the camshaft ( 6 ) and via the second overflow channel ( 12 ) past the second locking pin ( 10 ).

In umgekehrter Richtung strömt das Gasgemisch durch den ersten äußeren Überströmkanal (13) am Schließring (11), an der Nockenwelle (6) und über den zweiten Überströmkanal (13) am zweiten Schließring (11) vorbei.In the opposite direction, the gas mixture flows through the first outer overflow channel ( 13 ) past the closing ring ( 11 ), past the camshaft ( 6 ) and over the second overflow channel ( 13 ) past the second closing ring ( 11 ).

Zum Entkuppeln wird zuerst der Hebel (7) auf die Ausgangsposition bis zum Anschlag zurückgeschwenkt. Die Schließbolzen, bzw. Schließringe werden über Druckfedern zusammengedrückt und die Überlaufkanäle versperrt.To uncouple the lever ( 7 ) is swiveled back to the starting position as far as it will go. The locking bolts or locking rings are pressed together using compression springs and the overflow channels blocked.

Danach wird durch Zurückdrehen der Überwurfmutter (2) der Stecker (1) von der Kupplung (2) getrennt.The plug ( 1 ) is then separated from the coupling ( 2 ) by turning back the union nut ( 2 ).

Durch die plane Schließfläche, die versenkten Öffnernocken und die im geschlossenen Zustand eng bei einander liegenden Dichtringe wird eine leckagearme Trennung gewährleistet. Wird vor dem Trennen der Kupplung vergessen der Hebel (7) auf die Ausgangsposition zurückzuschwenken, so rastet das Gewindedruckstück (8) durch die zusätzliche Kraft (Druckdifferenz Leitung zur Umgebung über die Schließbolzenfläche) aus und der Hebel (7) schwenkt automatisch zurück. Die inneren und äußeren Überlaufkanäle werden durch den Schließbolzen, bzw. Schließring geschlossen.The flat closing surface, the recessed opening cams and the sealing rings that are close together when closed ensure a low-leak separation. If the lever ( 7 ) is forgotten to swivel back to the starting position before the clutch is disconnected, the threaded thrust piece ( 8 ) will disengage due to the additional force (pressure difference between the line and the environment via the locking pin surface) and the lever ( 7 ) will automatically pivot back. The inner and outer overflow channels are closed by the locking bolt or locking ring.
