View, taken from the forward end of the engine and under the turbine housing and gearbox, of the liquid propellant gas generator's injector assembly (round component with bumps protruding around the periphery) and LPGG control valve assembly (rectangular component forward of the injector assembly).

Picture 3 of 3.

Just aft of the injector assembly, pointing to the 2:00 position, is an igniter port. A pyrotechnic igniter would be mounted here to initiate combustion within the LPGG.
