How do hydraulic and pneumatic systems work?
“Anywhere” must mean “anywhere in my sock drawer.” Huge amounts of information are available on these topics, and a complete answer would be a couple of college engineering courses. You can’t really have looked very far. Try internet searches on “hydraulic system” and “pneumatic system.” If you try that and don’t find the information, pictures, and diagrams you want, you are doing something wrong or your computer is not hooked up to the internet correctly. If those searches don’t produce the information you need, then you need to ask someone who is knowledgeable about the internet to help you search. Good luck.
