I have inflation and deflation of a lid seal and deflation of the endoscope. The lid seal inflates so as to seal the machine and start the cycle, and then by pressing a button it is deflated so that the operator can open the lid. There is only this one reference for endoscope deflation.

I am thinking about διόγκωση/διαστολή for inflation and αποσυμπίεση/σύμπτυξη/συστολή for deflation, even though they are not antonyms. My favourites at the moment are διόγκωση - αποσυμπίεση.
