    摘要: 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.

    摘要: Devices for delivering fuel are already known, comprising a suction jet pump that is arranged in a storage crucible and has a nozzle and a mixer duct provided downstream of the nozzle and arranged perpendicular to the bottom of the storage crucible, wherein at the outlet of the mixer duct an impingement means is arranged, against which the jet of the nozzle impinges in the substantially unfilled mixer duct, and in doing so is at least partially returned into the mixer duct. It has been found that despite the impingement means the propulsive jet tends to eject the liquid column present in the mixer duct. As soon as the liquid level in the storage crucible has decreased below the outlet of the mixer duct, no more fuel can replenish from above into the mixer duct so that the mixer duct may be unfilled after switching off the suction jet pump. Upon restarting the suction jet pump, an unsatisfying high delay until suction of the suction jet pump occurs, because the volume of the propulsive jet must first fill the mixer duct in order to create a vacuum and suction power. Using the device according to the invention, a pushing out of the liquid column of the mixer duct by the propulsive jet of the suction jet pump is avoided. Thus the lead time of the suction jet pump is approximately equal in all operating states. According to the invention, an additional volume (25) is formed at the outlet of the mixer duct (16) by an off-set widening (26) of the mixer duct (16).

    摘要: The present invention includes a device that comprises a suction jet pump, that is arranged in a reservoir pot and has a nozzle and a mixing duct provided downstream the nozzle and arranged perpendicular to a pot base of the reservoir pot. The outlet of the mixing duct has a deflection means, which the jet of the nozzle impinges when the mixing duct is unfilled and has an additional volume formed at the outlet of the mixer by an offset widening of the mixer duct. This additional volume prevents the column of liquid in the mixing duct from being forced out by the propulsion jet of the suction jet pump. Thus the lead time of the suction jet pump is approximately equal in all operating states.
