This patent describes an exhaust gas turbine engine type supercharger for an engine, the supercharger having a turbine and a compressor, a casing means for receiving the turbine, partition wall means for dividing the casing means into two scroll chambers, and means for supplying an exhaust gas to the two scroll chambers to rotate the turbine and to feed the engine with supercharged air through the compressor. The supercharger comprises a bypass passage means for connecting one of the scroll chambers to a portion downstream of the turbine, a first flow rate control valve means for controlling a flow rate of the exhaust gas passing through the bypass passage means, and a second flow rate control valve means for controlling a flow rate of the exhaust gas being fed to the other of the scroll chambers, and means for controlling the first and second flow rate control valve means in accordance with an electric signal representing an engine RPM corresponding to a supercharged pressure.
