INTEGRATED FUEL INJECTORS AND IGNITERS AND ASSOCIATED METHODS OF USE AND MANUFACTURE
First Claim
1. A fuel injector configured to inject fuel into a combustion chamber, the fuel injector comprising:
- a body having a base portion opposite a nozzle portion;
a fuel passageway extending through the body from the base portion to the nozzle portion;
a force generator at the base portion;
a first valve carried by the base portion, wherein the first valve is movable in response to actuation from the force generator to move from a closed position and an open position to introduce fuel into the fuel passageway; and
a second valve at the nozzle portion, wherein the second valve is deformable in response to pressure in the fuel passageway to deform from a closed position and an open position to inject fuel into the combustion chamber.

Abstract
The present disclosure is directed to integrated injector/igniters providing efficient injection, ignition, and complete combustion of various types of fuels. One example of such an injectors/igniter can include a body having a base portion opposite a nozzle portion, and a fuel passageway extending from the base portion to the nozzle portion. A force generator and a first valve are carried by the base portion. The first valve is movable in response to actuation from the force generator to move between closed and open positions. The injector/igniter also includes a second valve at the nozzle portion that is deformable in response to pressure in the fuel passageway to deform between a closed position and an open position.

20. A fuel injector configured to inject fuel into a combustion chamber and to ignite the fuel in the combustion chamber, the fuel injector comprising:
-
a body having a base portion opposite a nozzle portion, wherein the base portion receives fuel into the body and the nozzle portion can be positioned adjacent to the combustion chamber; a casing at the base portion at least partially housing a force generator, wherein the casing includes a fuel inlet and a fuel outlet, wherein the fuel inlet is configured to receive fuel from a fuel source and the fuel outlet is configured to allow fuel to exit the casing; a fuel passageway fluidly coupled to the fuel outlet of the casing, the fuel passageway extending longitudinally through the body from the base portion to the nozzle portion; a first valve proximate to the force generator, wherein the first valve is movable in response to actuation from the force generator to move between a closed position and an open position to allow fuel to pass from the fuel outlet into the fuel passageway; and a second valve at the nozzle portion, wherein the second valve is movable in response to a predetermined fuel pressure in the fuel passageway to move between a closed position and an open position to inject fuel into the combustion chamber.
