Abstract: A turbocharger including a compressor housing, a flange, an air bypass valve and a seal. The compressor housing has an impeller housing, an upstream passage positioned upstream of the impeller housing and a downstream passage positioned downstream of the impeller housing. The flange is coupled to the compressor housing and has a bypass passage connected to the downstream passage of the compressor housing and the upstream passage of the compressor housing. A groove is formed at a surface of the flange opposing the compressor housing and the seal is fitted into the groove.
