Abstract

See full text

Variable flow rate fuel ejectors, and methods of use therefore, are disclosed. One variable flow rate ejector includes a primary nozzle, a needle, a motor, a first stop portion, and a first impact-absorbing portion. The primary nozzle is connected to a first inlet chamber to receive a first fluid and transmit a flow of the first fluid through the primary nozzle opening. The needle is disposed to create a gap between the tapered portion of the needle and the primary nozzle opening. The motor is coupled to axially move the needle to vary a size of the gap. The first stop portion delimits the axial movement of the needle in a direction of retraction of the needle from the primary nozzle opening. The first impact-absorbing element is positioned to contact the first stop portion or the needle, respectively, when the needle is fully retracted from the primary nozzle opening.
