Title:
FUEL EJECTOR ASSEMBLY FOR VEHICLE
Document Type and Number:
WIPO Patent Application WO/2018/210105
Kind Code:
A1
Abstract:
A fuel ejector assembly (1) for a vehicle, comprising: a first fluid passage (2) having an inlet flow port (3) and an outlet flow port (4) in fluid communication with each other, enabling a first flow of fuel (F1) to flow in the first fluid passage (2); a second fluid passage (5) connected to the first fluid passage (2), the second fluid passage having a suction flow port (6) arranged outside the first fluid passage and a nozzle opening (9), where the suction flow port (6) and the outlet flow port (4) are in fluid communication with each other, wherein the suction flow port (6) is connectable to a fuel tank suction passage (7) enabling a second flow of fuel (F2) to flow in the second fluid passage (5) from the fuel tank suction passage (7) via the suction flow port (6) to the outlet flow port (4); a flow shape unit (8) disposed within the first fluid passage (2) between the inlet flow port (3) and the outlet flow port (4), where the flow shape unit (8) is configured to raise the flow velocity of the first flow of fuel (F1) flowing in a direction from the inlet flow port (3) to the outlet flow port (4) when a first pressure level (P1) is applied to the inlet flow port (3), thereby subjecting the second fluid passage (5) to a second pressure level (P2), which is lower than the first pressure level (P1); wherein the second fluid passage (5) is extending into the first fluid passage (2) so that the nozzle opening (9) is arranged inside the first fluid passage (2) facing the outlet flow port (4) such that the first flow of fuel (F1) in the first fluid passage (2) is flowing around the nozzle opening (9), and wherein the flow shape unit (8) is disposed within the first fluid passage (2) in connection to the nozzle opening (9).
