Abstract
An ejector in the fuel tank for transferring liquid fuel from the fuel tank to a fuel chamber in the fuel tank. The ejector comprises a housing with an inlet opening from the fuel tank laterally into the housing. An inlet channel for surplus engine fuel communicates into the ejector housing through a nozzle orifice outlet. An evacuation channel from the ejector housing has an inlet that is aligned with the nozzle orifice. The conicity of the ejector housing and of the inlet channel in the vicinity of the nozzle orifice is disclosed. The evacuation channel has an outlet that extends essentially tangentially into the free space inside the fuel chamber around the outside of a fuel pump therein.
