An arrangement for forwarding fuel from a fuel tank to an internal combustion engine includes a fuel-forwarding device having a suction side and an elevated pressure side. An inlet conduit connects the suction side with the fuel tank, while a fuel-forwarding conduit forwards the fuel from the elevated pressure side. A fuel filter housing for accommodating a fuel filter surrounds the fuel-forwarding device. The fuel filter housing is connected with the fuel-forwarding device in an electrically conductive manner. One of the fuel filter housing and the fuel-forwarding device is connected to a location that is at a predetermined electrical potential.

Fuel-delivery module with an integrated fuel filter

An apparatus for pumping fuel from a tank ( ) to the internal combustion engine ( ) of a vehicle has a jet pump ( ), which supplies fuel returning from the internal combustion engine ( ) in a return line ( ) together with fuel disposed in the tank ( ) into a storage reservoir ( ) of a fuel delivery unit ( ). The invention proposes embodying a restriction ( ) for the fuel between a seat edge ( ) and a spring-loaded ball ( ). In addition, inlet openings ( ) for the fuel disposed in the tank ( ) are embodied in the vicinity of the restriction ( ). The apparatus has the advantage of a high delivery output, a compact design, and a delivery onset even when there are relatively low return quantities. Furthermore, fuel is prevented from flowing back into the return line ( ).

Device for conveying fuel from a tank to the internal combustion engine of a motor vehicle

The fuel delivery device (,) has a receptacle (,) arranged in a storage tank (,) and a delivery unit (,) delivering fuel from the receptacle (,) to the internal combustion engine (,) of a motor vehicle. Further, there is provided at least one suction jet pump (,) which delivers fuel from the storage tank (,) into the receptacle (,). The suction jet pump (,) is fastened to an upper edge area (,) of the receptacle (,) as a separate constructional unit. The suction jet pump (,) is formed by a constructional unit having a propelling nozzle (,), a connection (,) for a propelling line (,), which connection (,) opens into the propelling nozzle (,), a mixing pipe (,) following the propelling nozzle (,), and a connection (,) for a suction line (,), which connection (,) opens into the mixing pipe (,). Two walls (,) located at a distance from one another project downward from the constructional unit (,), and the constructional unit (,) is mounted on the edge (,) of the receptacle (,) from the top, wherein the edge (,) of the receptacle (,) is introduced between the two walls (,). The suction line (,) connected to the suction jet pump (,) opens into the storage tank (,) remote of the receptacle (,).
