Hi,
I've been asked to do an assignment about the workings of a beer pump. I've researched the history of the beer engine, but I think the question was more to do with the workings of a modern lager/bitter type pump. I've tried to see if there are any explanations on the web, but drawn a blank so far. Does anyone know of any websites that offer a simple explanation?
The assignment was half jokingly set, but I would like to do answer reasonably.
Thanks!
