Claims

[Scope of utility model registration request]

In a turbo supercharger with a movable vane type exhaust turbine nozzle, there is a controller to which detection signals from the engine rotation speed sensor, engine load sensor, and gear shift (accelerator pedal pressure release + clutch pedal depression) signals are input, and a controller for the controller. An on-off valve means that opens and closes a fluid pressure supply passage to the actuator in response to an output signal, an actuator cylinder that is actuated by the fluid pressure in accordance with the opening and closing operation of the on-off valve means, and a turbine of a supercharger connected to the actuator cylinder. A plurality of movable vanes are pivotally installed at the inlet, and the movable vanes are rotated to expand the turbine nozzle area as the engine speed increases, and to expand the turbine nozzle area as the engine load decreases. A variable nozzle area turbocharger configured to reduce the turbine nozzle area using a change gear signal.
