Has anybody got a link to any good diagrams/explanations of how the various parts of air brake systems work? I know the basics -press this, that happens, but would like to understand them in more detail. Have seen the diagrams on various sites in block form, but would like a breakdown of what each component is doing under what conditions (if any of that makes any sense!)

USA systems do (did) use some components not used in Europe. Below are a couple of examples which are not exactly up to date, but they explain how things work:
