Abstract

A turbocharger includes a waste gate valve, a compressor with a turbine, a turbine housing which houses the turbine, a bypass channel with an opening cross-section, a bypass channel portion formed in the turbine housing, an actuator housing with a separate coolant channel, an electric motor arranged in the actuator housing, a transmission with an output shaft, the transmission being arranged in the actuator housing and being provided as a worm wheel gear unit, and a control body coupled to the output shaft of the transmission. The bypass channel bypasses the turbine. The actuator housing is removably secured to the turbine housing. The control body controls the opening cross-section of the bypass channel.
