  • Patent number: 10746197
    Abstract: 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.

  • Patent number: 9719529
    Abstract: Devices, systems, and methods for variable flow rate fuel ejection are disclosed. A variable flow rate ejector comprises primary and secondary inlets, primary and secondary nozzles, and a needle. The primary nozzle is connected to receive a first fluid from the first inlet chamber and transmit the first fluid through a primary nozzle opening. The needle is disposed within the primary nozzle opening and is axially movable to vary an area of primary nozzle opening. The primary nozzle opening and the needle are sized to make the flow of the first fluid have a supersonic speed. The secondary inlet opens into a second inlet chamber positioned outside the primary nozzle opening. A portion of the second fluid is entrained in the flow of the first fluid from the primary nozzle. The secondary nozzle opening is sized to make the flow of the first and second fluids have a subsonic speed.

  • Publication number: 20090181286
    Abstract: Cell voltage measuring systems and methods for determining voltage levels across cells within a string of electrochemical cells coupled to each other in series are provided. The string of electrochemical cells has a plurality of tap points dispersed throughout the string. A network of electro-mechanical relays electrically couple to the string of electrochemical cells with each relay coupling to a respective tap point. A controller is coupled to the network of relays and selectively activates a pair of relays within the network responsive to a selection signal. Activation of the pair of relays develops an output voltage level that corresponds to the voltage across one or more cells between respective tap points of the activated pair of relays.
