Abstract
Die Erfindung betrifft eine Haltevorrichtung (1) zum Fixieren einer Kraftstoffpumpe (3) in einem Schwalltopf innerhalb eines Kraftstofftanks, wobei die Haltevorrichtung (1) einen Deckel (2) umfasst, der im eingebauten Zustand den Schwalltopf dicht verschließt. Der Deckel (2) ist derart kuppelförmig ausgebildet, dass die Schallemissionen der Kraftstoffpumpe (3) weitestgehend unterdrückt werden.The invention relates to a holding device (1) for fixing a fuel pump (3) in a swirl pot within a fuel tank, wherein the holding device (1) comprises a cover (2) which tightly seals the swirl pot in the installed state. The cover (2) is designed dome-shaped so that the sound emissions of the fuel pump (3) are largely suppressed.
Description
Die Erfindung betrifft eine Haltevorrichtung zum Fixieren einer Kraftstoffpumpe in einem Schwalltopf innerhalb eines Kraftstofftanks nach dem Oberbegriff des Patentanspruchs 1.The The invention relates to a holding device for fixing a fuel pump in a swirl pot within a fuel tank according to the preamble of claim 1
Bei
derartigen Intankkraftstoffpumpen treten im Betrieb Geräusche auf,
die über
die Wand des Pumpengehäuses
und den Pumpenkopf auf den im Tank befindlichen Kraftstoff und über diesen
auf die Tankwand übertragen
werden. Diese Geräusche
machen sich, insbesondere im Leerlauf des Fahrzeugsmotors, unangenehm
bemerkbar. Daher ist man dazu übergegangen,
die Kraftstoffpumpe im Tank elastisch zu lagern. Eine solche elastisch
gelagerte Pumpe ist aus

der
Aufgabe der Erfindung ist die Angabe einer Haltevorrichtung zum Fixieren einer Kraftstoffpumpe in einem Schwalltopf innerhalb eines Kraftstofftanks, die auf einfache Art und Weise die über den Pumpenkopf emittierten Geräusche wirksam dämpft.task The invention is the indication of a holding device for fixing a fuel pump in a swirl pot inside a fuel tank, the in a simple way the over noise emitted by the pumphead effectively dampens.
Die Aufgabe wird gelöst durch eine Haltevorrichtung mit den Merkmalen des Patentanspruchs 1. Bei dieser Haltevorrichtung ist der Deckel derart kuppelförmig ausgebildet, dass die Schallemissionen der Pumpe weitestgehend unterdrückt werden. Die direkt über dem Pumpenkopf befindliche erfindungsgemäße Kuppel zeigt vorteilhafterweise den Effekt, dass die Schallwellen in dem kuppelförmigen Gebilde im Gegensatz zu geraden Flächen nicht interferieren können, d.h. sie können sich nicht verstärken.The Task is solved by a holding device with the features of the claim 1. In this holding device, the lid is designed dome-shaped, that the noise emissions of the pump are largely suppressed. The directly over The dome according to the invention located in the pump head advantageously shows the effect that the sound waves in the dome-shaped structure in contrast to even surfaces can not interfere i.e. you can do not reinforce themselves.
In einer Ausbildung nach Anspruch 2 weist die Kuppel Öffnungen für einen Ein- und einen Auslaß auf. Die Öffnung für den Einlaß dient dem Anschluß einer Saugstrahlpumpe, der Auslaß dem Anschluß eines Schlauches für einen Pumpenvorlauf. Beide Öffnungen sind zusammen mit den jeweiligen Anschlüssen zum Tankinneren hin weitestgehend luft-/schalldicht ausgelegt.In an embodiment according to claim 2, the dome openings for one Inlet and outlet on. The opening for the Inlet serves the connection of a Suction jet pump, the outlet of the Connection of a Hose for a pump flow. Both openings are together with the respective connections to the tank inside largely air / soundproof designed.
In einer Weiterbildung nach Anspruch 3 ist in der Haltevorrichtung eine zweite Pumpe vorgesehen, wobei der Deckel zwei kuppelförmige Ausbildungen mit jeweils zwei Öffnungen umfasst.In a development according to claim 3 is in the holding device provided with a second pump, wherein the lid has two dome-shaped formations two openings each includes.
Ferner ist in einer bevorzugten Ausführungsform nach Anspruch 4 der Deckel aus einem kraftstoffbeständigen Polymer- oder polymerhaltigen Material gebildet.Further is in a preferred embodiment according to claim 4, the lid of a fuel-resistant polymer or polymer-containing material.
In einer vorteilhaften Weiterbildung nach Anspruch 5 weist die Kuppel eine Wandstärke von mindestens 1,5 mm auf.In An advantageous development according to claim 5, the dome a wall thickness of at least 1.5 mm.
Besonders bevorzugt liegt die Wandstärke der Kuppel in einem Bereich von etwa 2 bis 5 mm.Especially Preferably, the wall thickness of the Dome in a range of about 2 to 5 mm.
In einer Ausführungsform nach Anspruch 6 weist der Deckel eine Wandstärke von mindestens 1 mm auf.In an embodiment according to claim 6, the lid has a wall thickness of at least 1 mm.
Vorteilhafte Ausgestaltungen der erfindungsgemäßen Haltevorrichtung sind Gegenstand der Unteransprüche und der Beschreibung.advantageous Embodiments of the holding device according to the invention are the subject the dependent claims and the description.
Die Erfindung wird nun anhand der beigefügten Zeichnung weiter beschrieben. In dieser zeigt:The Invention will now be described with reference to the accompanying drawings. In this shows:
