Thank you for your excellent description of something I never
understood before. Or even knew the name of.
The attached pic of a steam cylinder is NOT a compound then? Right?
The small "cylinder" is there to only to lead the steam to the right
side of the piston? In a compound there would be an extra cylinder for
the first expansion?
