A device for pumping air into or out of an enclosed space
A pump is a device used to move fluids, such as liquids or slurries.
(Air pumping) Flow of air between the belt and pulley. The air will be squeezed out when the belt teeth engage the pulley and air will rush in when the belt disengages from the pulley.
A piston is a component of reciprocating engines, pumps and gas compressors. It is located in a cylinder and is made gas-tight by piston rings. In an engine, its purpose is to transfer force from expanding gas in the cylinder to the crankshaft via a piston rod and/or connecting rod.
