Abstract
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.
