A fuel injector includes a fuel nozzle configured to issue a spray of fuel from a fuel outlet in a downstream direction along an injection axis. The fuel nozzle defines a main flow passage therethrough. An injection fuel line is in fluid communication with the fuel nozzle to supply fuel to the fuel nozzle. A torch ignitor has a flame outlet opening into the main flow passage of the fuel nozzle for issuing flame into the main flow passage.

An embodiment of a torch igniter for a combustor of a gas turbine engine comprises a combustion chamber oriented about an axis, a cap defining an axially upstream end of the combustion chamber and oriented about the axis, a tip defining an axially downstream end of the combustion chamber, a structural wall coaxial with and surrounding the igniter wall, an outlet passage defined by the igniter wall within the tip, and a cooling system. The cooling system comprises an air inlet formed within the structural wall, a first flow path disposed between the structural wall and the igniter wall, and an aperture extending through the igniter wall transverse to the flow direction. The aperture directly fluidly connects the first flow path to the combustion chamber.

A handheld computer case having an integral lighter for providing a flameless lighter in a case for a mobile phone includes a case body defining a rigid housing sized to fit a conventional handheld computer, a lighter actuator for selectively availing and activating an electric lighter, and a lighter housing in which the electric lighter is disposed. In operation, a user may apply manual force to mechanically actuate the lighter actuator, thereby causing both the lighter housing to open and expose the electric lighter and an electrical switch to direct electricity from an internal battery to a heating element which defines the electric lighter. Once the user is finished with the lighter, the manual force may be removed to cause the lighter housing to automatically close and the flow of electricity to the heating element to be interrupted.
