Abstract: The fuel delivery device (12) has a receptacle (16) arranged in a storage tank (10) and a delivery unit (20) delivering fuel from the receptacle (16) to the internal combustion engine (14) of a motor vehicle. Further, there is provided at least one suction jet pump (40) which delivers fuel from the storage tank (10) into the receptacle (16). The suction jet pump (40) is fastened to an upper edge area (17) of the receptacle (16) as a separate constructional unit. The suction jet pump (40) is formed by a constructional unit having a propelling nozzle (41), a connection (43) for a propelling line (44), which connection (43) opens into the propelling nozzle (41), a mixing pipe (42) following the propelling nozzle (41), and a connection (45) for a suction line (46), which connection (45) opens into the mixing pipe (42).

Abstract: A fuel container for a motor vehicle has at least two supply chambers and a withdrawal chamber, a fuel pump feeding fuel from the withdrawal chamber, a pump circulating device operating in accordance with the principle of a suction jet and circulating fuel from at least one of the supply chambers into the withdrawal chamber, the pump circulating device including a single nozzle through which at least a part of a fuel stream fed by the fuel pump passes through it, and at least two suction pipes arranged one after the other in alignment with one another in a fuel jet produced by the nozzle and having suction inlets which communicate with a respective one of the supply chambers, a last one of the suction pipes having an outlet which faces away from the nozzle and is connected with the withdrawal chamber.

Abstract: Arranged in the fuel tank is a reservoir into which fuel is pumped by a jet pump connected to a return line from the internal combustion engine. The jet pump has a jet nozzle which is arranged in a holder formed on the reservoir. Between its inlet opening and the propulsion-nozzle opening, the jet nozzle has a bypass opening which is connected to a stub projecting into the reservoir. At its end, the stub is provided with a seat which can be closed by a closing element. Arranged in the reservoir is a leaf spring which is fixed at one end and which presses the closing element onto the seat. Together with the closing element, the bypass opening forms a bypass valve which allows fuel to flow out of the jet nozzle if a certain pressure is exceeded.
