  • Preliminary filter for a fuel delivery unit
    Patent number: 8784656
    Abstract: A preliminary filter for a fuel delivery unit of a motor vehicle, with a filter fabric which is tensioned by a supporting edge. The supporting edge is manufactured integrally with a connecting piece for connection to the fuel delivery unit and with transverse webs and supporting ribs. The preliminary filter has few components to be assembled and can be manufactured particularly cost-effectively.

  • Housing
    Patent number: 7523838
    Abstract: The invention relates to a housing which is composed of two housing halves (1a, 1b) that form a bottom (5) and a lid (6) and an intervening section (7). According to the invention, sections of the walls of the two housing halves (1a, 1b) are configured as respective peripheral rims (10, 11) which are joined to each other while overlapping, thereby increasing the wall thickness in the area of the rims (10, 11). The rims (10, 11) thus contribute to the wall thickness required to impart to the housing the necessary stability.

  • Fuel filter for a motor vehicle
    Publication number: 20060207929
    Abstract: The invention relates to a fuel filter for a motor vehicle. According to the invention, two cover disks (5, 6) retainingi a filter tissue (7) are produced as one piece with one half of a support cage (8) of the filter tissue (7) each. The cover disks (5, 6) have an identical structure and can be fitted together. This permits the fuel filter to be produced in a particularly cost-effective manner.
