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 (	01-26-2012
