General Engine Question: A.I.R. Pumps - How do they work?

Hi All,


I just had a few general questions regarding A.I.R. pumps that I wasn't able to find the answers to online.


How exactly does a A.I.R. pump operate internally? I am working on my '77 Chevy truck (non-EGR) and have a few things removed. I see the A.I.R. pump operates off the v-belt, so it obviously operates based on engine speed.


Also, how can one tell if the A.I.R. pump has gone bad? Do they eventually go bad?


Thanks in advance!
