What is that power steering smell?

Of all the vehicles i have ever worked on no matter if atf or power steering fluid was used everytime i smell the reservoir they all smell the same like that strange semi burnt smell. It doesn't seem to matter the make of vehicle. If the power steering pump uses atf it smells much different than the atf in the trans after it has been used. What is it about power steering systems that make them all smell the same. I know this is a weird question.

Not a weird question at all. It is due to the elastomeric materials of which the seals and hoses are made.
