These are meshing rotors suitable for low pressure ratios only. There is no built-in compression ratio, any increase in pressure being achieved by compressing against the back pressure in the system. Such a device is inefficient, its real advantage lying in the simplicity of manufacture. Figures 20 and 21 show an example of this type- the Roots blower.
