Martin,
As you pointed, it would have been nice if the GDC would stated which rule applied. The user had specifically asked if a cylinder (they used the term piston) could be used as a shock absorber without being

R66J defines a cylinder as a pneumatic component.
R70A defines that all working pneumatic components must be connected to the working pressure side of the pneumatic system.

I was wondering why someone would want to do this. I believe Chuck answered that question for me in the previous post. I do believe using an independent cylinder with restricters would violate R70A.

I guess the GDC left us guessing on this one.
