atmospheric pressure: the pressure exerted by the atmosphere
The air around us constantly exerts a pressure of about 400 inches of water. That means that every exposed surface has the equivalent of 400 inches of water pushing on the surface. A vacuum cleaner doesn't actually create a vacuum, but it does lower air pressure inside the vacuum unit.

Riviting!
Nice display of various styles of riviting on a air "reciever" . These were mounted on the pressure side of reciprocating water pumps to even out the flow. An airlock was allowed to form in the top of the tank and its elastic properties acted as a spring as the impulses from the pump alternately raised and lowered the water level.
