Reply to "Where was the post that talked about sucking and atmospheric pressure?"

No, it was written yesterday.

It was explained that "suction" by the pistons doesn't exist, but that the pistons going down simply creates a volume in which the atmospheric pressure pushes the air, the atmospheric pressure being caused by the gravity exerted on the gas that constitutes the Earth's atmosphere.

In other words, it is not the piston that pulls but the atmospheric pressure that pushes.
This is a subject on which my old physics professor had insisted a lot a long time ago ................. when I was young and still in high school.
