Beschreibung
Zusammenfassung:	A turbocharger (101) having a turbine with a wastegate, and a compressor including a compressor housing (107), a compressor wheel (113), and a wastegate actuator. A turbine wheel (111) includes blades defining an inlet (145). The compressor housing (107) has an inlet wall (213) leading to the inlet, and a shroud wall (221) surrounding the blades. The actuator includes a base (245) that is integral with the inlet wall (213), and an electric motor (231) that is attached to the base (245). The shroud wall (221) forms a first port (251) that is in direct fluid communication with the actuator chamber (241), and the inlet wall (213) forms a second port (253) that is in direct fluid communication with the actuator chamber (241). Air from the first port (251) passes through the actuator housing (243) and out the second port (253). This airflow convectively cools the working components of the actuator, while the connection of the motor (231) to the inlet wall (213) conductively cools the motor (231).
