Turbocharger for an internal combustion motor, using the motor exhaust gas, has a control with moving arc segments to alter the outflow cross section of the spiral channel

摘要

The exhaust gas turbocharger (10), for an internal combustion motor, has a turbine section (12) with a spiral channel (16) for an exhaust gas flow (14) leading to the turbine wheel (22). A control (28), with moving arc segments, forms an outflow cross section (40). The control can be moved steplessly between a closed (34) and an open position.
