  • Fuel pump delivery unit
    Patent number: 6716000
    Abstract: A fuel delivery unit (2) for delivering fuel from a tank (1) in which a support (6) connects a flange (4) to a surge chamber (5) through a pivot bearing (12). The pivot bearing (12) makes it possible to introduce the delivery unit (2) in an elongated state into the fuel tank (1) through a particularly small opening. Within the fuel tank (1) the surge chamber (5) is locked in its designated position.

  • Delivery unit
    Publication number: 20020153300
    Abstract: In previous feed units with a fuel pump arranged in them, the inlet of the fuel pump is preceded by a filter. Filters of this type consist, as a rule, of a tubular filter fabric, into which a supporting body maintaining the shape is inserted. These filters lie only in a part region of the baffle due to their shaping, with the result that the supply of fuel to the fuel pump is impaired, particularly in the case of a low fuel level.
