Venturi Pump legality

Depends somewhat on the application, and how much vacuum you're actually pulling.

I'll vouch that for short-term pickups without a lot of shock loading, it'll work fairly well. And it'd probably work for somewhat longer runs if you had enough. The problem is that FRC robots get rocked a lot... I've seen two teams attempt this in one season (it's been a while, though), with some degree of success. I was on one of those teams. We took the device off because, while it fit part of our strategy, it didn't fit the rest properly and couldn't hold suction in a shock situation. (It was replaced by a long piece of fiberglass pultrusion, actuated by the cylinder that had supplied the motion to the vacuum-generating one--lost half the job, kept the really important half.)

Just so you know, I had no idea what a Venturi Pump was when I started this article, but reading this. A little internet research later, I do, and this is why I like CD.
