摘要： A method and a device are described for diagnosing a fuel system having a plurality of electric fuel delivery units, which are submerged on the inlet side in a fuel supply contained in a fuel tank, and which, on the outlet side, deliver fuel in a fuel line to an internal combustion engine. The currents of the electric fuel delivery units are measured directly or indirectly in an analysis unit, compared to one another, and a diagnostic signal in digitized form is generated as a function of the result of the comparison.

摘要： The invention relates to a fuel supply system for an internal combustion engine, having a unit such as a pressure regulator, mounted in electrically insulated fashion and including an electrically conductive housing, and the housing is connected via an electrical connection to a defined electrical potential. As a result, static charging of the unit, which could become dangerous, is precluded. The fuel supply system is intended in particular for pumping fuel to an internal combustion engine of a motor vehicle.

摘要： 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). Two walls (48) located at a distance from one another project downward from the constructional unit (40), and the constructional unit (40) is mounted on the edge (17) of the receptacle (16) from the top, wherein the edge (17) of the receptacle (16) is introduced between the two walls (48). The suction line (46) connected to the suction jet pump (40) opens into the storage tank (10) remote of the receptacle (16).

摘要： An aggregate for feeding fuel from a supply tank to an internal combustion engine of a motor vehicle has a feed pump formed as a flow pump and having a disk-shaped impeller and a pump chamber in which the impeller rotates and which is limited in an axial direction by two end walls spaced from one another and in a radial direction by a ring wall arranged so that substantially parallel axial gaps are formed between end surfaces of the impeller and end surfaces of the pump chamber facing the end surfaces of the impeller. Each of the axial gaps has an inner ring-shaped throttle gap with an inner throttle gap area and an outer ring-shaped throttle gap with an outer throttle gap area as considered in a radial direction and formed so that when the axial gaps are identical at any distance from the rotary axis the inner and outer throttle gap areas are identical, but when the axial gaps are not identical, then at a side of a smaller axial gap the inner throttle gap area is greater than the outer throttle gap area and at the side of a greater axial gap the outer throttle gap area is greater than the inner throttle gap area.
