Abstract

A turbocharger includes a waste gate valve, a compressor, a turbine, a turbine housing which houses the turbine, a bypass channel which bypasses the turbine, a bypass channel section arranged in the turbine housing, an actuator housing which has a separate coolant channel, an electric motor arranged in the actuator housing, a transmission which has an output shaft, a control body coupled to the output shaft, and an actuator cover. The transmission is arranged in the actuator housing. The actuator housing is detachably secured to the turbine housing. The control body controls an opening cross-section of the bypass channel. The separate coolant channel of the actuator housing surrounds a circumference of the transmission and is closed axially by the actuator cover.
