ACTUATOR ASSEMBLY WITH SEALING ARRANGEMENT

The present invention relates to an actuator assembly 10 for a charging apparatus 700. The inventive actuator assembly 10 comprises an actuator shaft 200, a bushing 300 and a sealing arrangement 100. The sealing arrangement 100 comprises an insert sleeve 400 and a seal ring 500. A radial sealing region 110 and an axial sealing region 120 are defined by the sealing arrangement 100. The radial sealing region 110 is formed between the bushing 300 and the seal ring 500. The axial sealing region 120 is formed between the seal ring 500 and the insert sleeve 400. The seal ring 500 is configured and arranged to be driven into contact with the insert sleeve 400 by exhaust gas pressure.
