Valve Design

<< < (3/3)

MJP:
The reason I pointed out the choke point is the fact some AF valves are exactly like drawn here.

If the OP has been looking one of those for ideas.
Drawing is always the first step, or should be and then calculating the desired dimensions.

Interesting idea with two barrel design, I hope we see more than just a picture on paper.

CableStop:
I see what you mean now I was totally missing the point.  So the stem area has to offset the force on the rear of the poppet since the front face doesn't have pressure on it. 

On the note of choke points, I think you would use multiple holes around the circumference of the poppet tube not just one as shown in the drawing.  I just showed one to make it easier to draw.
