  • Device for supplying fuel from a tank to the internal combustion engine of a motor vehicle
    Patent number: 6868836
    Abstract: A suction jet pump for delivering fuel from a tank to the internal combustion engine of a motor vehicle is driven by fuel flowing back from the engine and delivers fuel from a tank into a collecting receptacle of a fuel delivery unit. The suction power of the pump is not limited by the propulsive jet lying against the housing wall so that the entire propulsive jet surface is no longer available for the entrainment of fuel, as in the prior art, but instead the fuel is aspirated from intake openings, which are disposed opposite each other in pairs. This permits the suction power to be noticeably increased.
