Yeah, I did a pretty poor job describing what I meant.
The solid light grey areas (where you can see the cutaways of the threaded ports), don't seem to allow the air from the ports to actually go anywhere (except for the port on the blind end of the cylinder).
If the cylinder is built like the diagram in Travis' post shows, then there is clearance around the rod to allow airflow, but as it is, I'm not seeing it.
