    Abstract: A unitary fuel injector and nozzle assembly comprising a high-pressure piston pump and a cylinder body that define a high-pressure fuel pump chamber. An injector nozzle assembly is in fluid communication with the pump chamber and is held in place by a nozzle nut detachably secured to the cylinder body. A nozzle valve assembly includes a spring located in a spring cage within the nozzle nut. A control module is assembled between the cylinder body and the spring cage, the module including a module body having a valve chamber that receives a control valve and a stator assembly as separate and removable elements of the module whereby the stator assembly, the nozzle valve assembly and the control valve can be changed independently of the other elements of the injector to meet various operating requirements.
