Relating to compressors and turbines |
摘要 |
A centripetal compressor includes a compressor housing, a compressor wheel mounted within the housing and having compressor blades. The compressor housing comprises a cover plate and a diffuser flange that is fixed to both the cover plate and to a bearing housing. The diffuser member has an outer peripheral portion attached to the cover plate and a radially inner portion attached to the bearing housing. A frangible groove or weakened section is defined in the diffuser at a position intermediate the outer peripheral and the radially inner portions so as to enable predictable fracture of the diffuser flange during failure of the compressor wheel. The same principle is applied to the turbine of a turbocharger.
