ABSTRACT:
Known apparatuses for pumping fuel have at least two suction jet pumps, which each have one drive nozzle and one collection conduit and mixing conduit located downstream of the drive nozzle. A disadvantage is that the parallel suction jet pumps require a large amount of installation space, are embodied very massively, and therefore require a large amount of injection-molding compound for their manufacture. In the apparatus of the invention, the production costs and the required installation space for the suction jet pumps are reduced. According to the invention, the drive nozzles are surrounded by a single collection conduit, narrowing conically in the flow direction and located upstream of the mixing conduits.
