A Roots type blower wherein a secondary gap distance for rotor is determined in accordance with a cross angle between a normal line at a point of the outer periphery of theoretical base curve of the rotor and a line extending through said point and the rotor center.

Roots type blower with reduced gaps between the rotors

An apparatus for controlling a supercharger driven by an engine or exhaust gas is controlled in response to primarily the changing rate of accelerator (pedal) position, and additional parameters such as time after supercharging start and/or vehicle speed and transmission gear shift position, etc. so that it can precisely respond to the acceleration requirements by the driver with good accelerating performance and fuel economy.
