ABSTRACT:
A turbocharger for supercharging an engine provided with an intake pipe and an exhaust pipe including a main pipe and a branched pipe disposed in parallel thereto includes a compressor rotor disposed in the intake pipe, a first turbine rotor disposed in the main pipe so as to be rotated by the pressure of the exhaust fluid therein and connected to the compressor rotor for the rotation thereof, a second turbine rotor disposed in the branched pipe so as to be rotated by the pressure of the exhaust fluid therein, a coupling device for establishing the connection between the first and second turbine rotors when the either of the turbine rotors is brought into rotation at a speed above a set value, a valve disposed between the main pipe and the branched pipe and being normally closed for interrupting the fluid communication therebetween, a sensor for detecting the rotational speed of the first or the second turbine rotor and a control device for opening the valve based on a signal from the sensor when the detected rotational speed exceeds the set value.
