Abstract

A purge ejector assembly for a vehicle, comprising a first fluid passage having an engine flow port and an air channel flow port in fluid communication with each other; a second fluid passage connected to the first fluid passage, the second fluid passage having a purge flow port arranged outside the first fluid passage and a nozzle opening, where the purge flow port and the air channel flow port are in fluid communication with each other, wherein the purge flow port is connectable to a canister purge passage enabling evaporated fuel to flow in the second fluid passage from the canister purge passage via the purge flow port to the air channel flow port; a flow shape unit disposed within the first fluid passage between the engine flow port and the air channel flow port, where the flow shape unit is configured to raise the flow velocity of air flowing in a direction from the engine flow port to the air channel flow port when a first pressure level is applied to the engine 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 air channel flow port such that the flow of air 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.
