Not so sure you would get everything back. As the air is compressed it
heats, if the heat is greater than the surrounding walls and rotor some of
the heat (energy) will transfer out of the air charge. Leaving the charge
with less energy than was put into it.

Other than friction losses, you'll get back everything you put into
compressing the gas in the cylinder, Rusty. The process will be totally
elastic.
