  • Ejector pump
    Patent number: 6619927
    Abstract: An ejector pump for a delivery unit provided in a fuel tank of a motor vehicle has a nozzle produced integrally with a mixing tube. The mixing tube is shaped in the form of a tubular cylinder, so that virtually the entire ejector pump may be produced from plastic in a mold allowing axial demolding. The nozzle is therefore aligned,exactly with respect to the mixing tube. The ejector pump consequently has a particularly high efficiency.
