Zusammenfassung:A fuel ejector assembly for a vehicle, comprising a first fluid passage having an inlet flow port and an outlet flow port in fluid communication with each other, enabling a first flow of fuel to flow in the first fluid passage; a second fluid passage connected to the first fluid passage, the second fluid passage having a suction flow port arranged outside the first fluid passage and a nozzle opening, where the suction flow port and the outlet flow port are in fluid communication with each other, wherein the suction flow port is connectable to a fuel tank suction passage enabling a second flow of fuel to flow in the second fluid passage from the fuel tank suction passage via the suction flow port to the outlet flow port; a flow shape unit disposed within the first fluid passage between the inlet flow port and the outlet flow port, where the flow shape unit is configured to raise the flow velocity of the first flow of fuel flowing in a direction from the inlet flow port to the outlet flow port when a first pressure level is applied to the inlet flow port, thereby subjecting the second fluid passage to a second pressure level, which is lower than the first pressure level, wherein the second fluid passage is extending into the first fluid passage so that the nozzle opening is arranged inside the first fluid passage facing the outlet flow port such that the first flow of fuel in the first fluid passage is flowing around the nozzle opening, and wherein the flow shape unit is disposed within the first fluid passage in connection to the nozzle opening.
