In mechanics, a diaphragm is a sheet of a semi-flexible material anchored at its periphery and most often round in shape. It serves either as a barrier between two chambers, moving slightly up into one chamber or down into the other depending on differences in pressure , or as a device that vibrates when certain frequencies are applied to it.
A diaphragm micropump uses the repeated actuation of a diaphragm to drive a fluid. The membrane is positioned above a main pump valve, which is centered between inlet and outlet microvalves. When the membrane is deflected upwards through some driving force, fluid is pulled into the inlet valve into the main pump valve.
The basic working principle of an air-operated double diaphragm pump. Cross-section sketch of diaphragm fuel pump Air-operated double diaphragm pump. A diaphragm pump (also known as a Membrane pump) is a positive displacement pump that uses a combination of the reciprocating action of a rubber, thermoplastic or teflon diaphragm and suitable valves on either side of the diaphragm (check valve ...
A simple diaphragm pump contains a chamber that acts like a springy diaphragm. When compressed, the air within the diaphragm gets expelled. When the diaphragm is decompressed, the chamber refills with air. A simple example for a diaphragm pump is a foot pump that requires the user to constantly step up and down on the pump to inflate something.

It is a large, sealed horizontal cylinder (or "tank") in which the patient lies, with their head protruding from a sealed opening at one end of the tank. An air pump or a flexible diaphragm (usually motor-driven) varies the air pressure inside the tank, in continuous alternations, lowering and raising the air pressure in the cylinder. This ...
