The base of the nozzle is where the nitrous jet is installed; the jet is simply a brass cone with a tiny orifice to control the volume of nitrous that makes it to the engine.
Since nitrous oxide systems receive some of their fuel from the factory fuel system, it's important that the nitrous isn't triggered unless the factory fuel system is delivering as much fuel as possible — this means not firing the nitrous unless the engine is at wide-open throttle.
