A check valve is basically a vacuum delay valve that holds off vacuum or pressure for a calibrated pre determined amount of time.
A handheld vacuum pump tester with gauge is indispensable to check any vacuum related system.

Rocketman,
Wikipedia, the free OnLine encyclopedia agrees more with you than me!
Check out their definition at:
http://en.wikipedia.org/wiki/Dashpot
"A dashpot is a mechanical device, a damper which resists motion via viscous friction. The resulting force is proportional to the velocity, but acts in the opposite direction, slowing the motion and absorbing energy. It is commonly used in conjunction with a spring (which acts to resist displacement)."
And as I stated before MBZ calls this vacuum chamber a "surge dampener".
Maybe we need a "Glossary of Terms" for the WebSite/FORUM... for many times I have seen where we get caught up in terms... and this is proof that this includes myself as well. I have seen parts sources call this a "dasPot" and so that's what I started calling it. There are different names used for many different vacuum parts on these Vintage MBZs and some of this I'm sure is due to translation problems.
