Abstract
A suction jet pump provided for the conveyance of fuel in a fuel tank has a separate nozzle insert with a nozzle duct. The nozzle insert can be produced both from plastic by the injection-molding method or from metal. By virtue of the smaller component size in the case of plastic or due to the choice of metal as material for the nozzle insert, the nozzle duct can be provided with a particularly small diameter. The suction jet pump has a particularly low propellant consumption.
Claims11
A suction jet pump for the conveyance of fuel in a fuel tank, comprising:
- a nozzle arranged upstream of a mixing tube and configured for connection to a propellant line;
- and
- a nozzle duct, wherein
- the nozzle has a nozzle insert in the region of the nozzle duct.
A method for producing a nozzle for a suction jet pump having a nozzle arranged upstream of a mixing tube and configured for connection to a propellant line and a nozzle duct, wherein the nozzle has a nozzle insert in the region of the nozzle duct, comprising:
- manufacturing the nozzle insert as a separate component from plastic by the injection-molding method, the nozzle duct being made during injection molding.
A method for producing a nozzle for a suction jet pump having a nozzle arranged upstream of a mixing tube and configured for connection to a propellant line and a nozzle duct, wherein the nozzle has a nozzle insert in the region of the nozzle duct, comprising:
- working the nozzle duct into plastic, after the manufacture of the nozzle insert from metal or plastic.
