The invention concerns a motor vehicle fuel drawing assembly comprising a housing ( ) having a ring-shaped chamber ( ) and a filter ( ) arranged in said ring-shaped chamber. The invention is characterised in that it comprises at least a plastic annular lip ( ), cast in one single piece linked to the housing ( ) or to the filter ( ), made of a material capable of being elastically deformed, and shaped along an oblique direction relatively to the axis O-O of the filter ( ) and the housing chamber ( ), such that said lip ( ) is urged to rest, with elastic deformation, and along a direction with tangential components by its free end ( ), against the surface opposite ( ), the other surface of the filter ( ) or of the housing ( ) arranged substantially transversely to the axis (O-O) of the filter ( ) of the housing ( ) chamber ( ) to ensure tightness at that level between the filter ( ) and the housing ( ).

Filtering means for fuel drawing assembly

The present invention relates to a fuel-drawing assembly for a motor vehicle tank, the assembly comprising a main pump ( ) associated with a pressure regulator ( ) and a reserve bowl ( ) fed by a jet pump ( ) and from which the main pump ( ) draws fuel, the assembly being characterized by the fact that the jet pump ( ) is integrated in the outlet from the pressure regulator ( ), and that the jet pump and regulator ( and ) subassembly formed in this way is secured to a module ( ) comprising the main pump ( ) and the reserve bowl ( ), a portion of the housing ( ) for the pressure regulator ( ) being integrated in the wall constituting the reserve bowl ( ).

Assembly for transferring fuel from a motor vehicle tank

A fuel gauging system for a motor vehicle fuel tank, including a housing (,) supporting a resistive element (,), an arm (,) pivotally mounted on the housing (,) and comprising at least one cursor (,) engaging the resistive element (,), and a lever (,) provided with a float connected to the arm (,) for monitoring the movements thereof. The system includes a housing (,) and an arm (,) which comprise complementary rotational guides (,) and structure (,and,) to enable translation of the arm (,) on the housing (,). The arm (,) is combined with an L-shaped lever (,) so that one of the sections (,) defines the pivot axis of the device.
