The operation of a diaphragm compressor can be divided into four stages: intake, compression, exhaust, and reset. During the intake stage, the diaphragm moves to one side, increasing the volume of the compression chamber and creating a negative pressure. Gas is then drawn into the compression chamber through the intake valve.

During the compression stage, the diaphragm moves in the opposite direction, decreasing the volume of the compression chamber. The gas is compressed, and the pressure increases. When the gas pressure reaches the opening pressure of the exhaust valve, the exhaust valve opens, and the gas is discharged. In the reset stage, the diaphragm returns to its initial position, preparing for the next intake cycle.
