In dynamic compression, air is drawn between the blades on a rapidly rotating compression impeller and accelerates to a high velocity. When the pressure has reached the designed build-in pressure ratio, a port or valve is opened and the air is discharged into the outlet system due to continued reduction of the compression chamber's volume. Gradually the volume of each chamber decreases and the air is compressed internally. In positive displacement compression, the air is drawn into one or more compression chambers, which are then closed from the inlet. The first one includes, for example, reciprocating (piston) compressors, orbital (scroll) compressors and different types of rotary compressors ( screw, tooth, vane).
There are two generic principles for the compression of air (or gas): Positive displacement compression and dynamic compression.
