Hello!
This is my first post, and I hope it is a useful one.
I am making a 3D model of the complete injector assembly using Autodesk Inventor.
I've already made the plug housing (2-2) and the water inlet housing (2-3) exact to Stan's specifications. There is however some guesswork with the inlet threading and size. It would appear to me that the all the drawings throughout this design are inconsistent with each other and are not to scale with the measurements, however they do fit together.
I do have a few questions that I hope someone can help me clear up.
In figure 2-4, there is a label that says .110 DIA. STOP-SEAL SURFACE. What exactly is a "stop-seal surface," what does it imply?
In some of the measurements there are negative numbers in parentheses, usually very small on the scale of thousandths. What are these numbers for? Are they for fabrication accuracy?
And another question is about the functionality of the injector. Is the injector always supposed to be open? That is, there is no way to stop water from coming out the tip of the injector from the pressurized water inlet port?
One last thing that I've noticed is that no water can make it through the quenching circuits because of the way the ceramic sits inside the water inlet housing and the way both of those sit inside the injector housing. With one slight modification to how long the end of the ceramic insert is however, this problem can be fixed.
And now for why you came here. These models are my best interpretations of the drawings. These models do not have the fix stated above.
(Please note that the drawings may not be to size. )



You can download the models below. If you would like a different model file, please post and I'll see what I can do.
