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

This one?

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.

Gay-Lussac? no I don't see why, but however he could have been called Blaise Pascal but I'm still not so old

well seniors..smile
think the whole thing is a question of the science disciplines.

Thermodynamic folks call it this way.. Engineering folks the other way .. well physics still stands, as "phenomens" are the same! ...To my old brain top guys from France investigation this..in the 18th and 19th century..

Enjoy..and my engine is runing!!!

I agree, Gay-Lussac is thermodynamics, the law of the perfect gas, but the atmospheric pressure it's Pascal but no matter, you're right they were both French
