Device for delivering fuel

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
