How Nitto Medo Air Pump Works, Operating Principle
Within the Medo Air Pump the activated electro magnate attracts the piston against a return spring, whilst air is drawn into the cylinder through the open inlet valve. Once the elctro magnate is deactivated, the return spring pushes the piston back, compressing the air. The compressed air is now brought out of the cylinder through the now open outlet valve. Medo air pumps can function as as either a compressor or as a vacumn pump.
