Turbocompressor with variable turbine rotor speed

摘要

The turbocompressor has a shaft with the turbine rotor (13) coupled to one end and a chamber (11) in which the rotor turns. The chamber has an exhaust gas intake (11a) and outlet, and a spiral section linking them via the rotor. A partition (32) divides the spiral section into inner (30) and outer (31) compartments and has a number of apertures connecting them, while the intake end of the outer spiral compartment is controlled by a shutter (40) linked to the accelerator pedal.
