ABSTRACT:
A turbocharger (10) for an internal combustion engine includes a compressor (12) having an impellor (16) disposed in a compressor chamber (18). The compressor chamber (18) receives fluid flow. A flow regulation mechanism (30) is disposed in the compressor (12) and includes a diffuser cover (32) and a recirculation gate (36). The diffuser cover (32) is moveably disposed in a diffuser passage (34) from a first position permitting fluid flow through the diffuser passage to a second position at least partially impeding the fluid flow. The recirculation gate (36) is moveably disposed in the compressor chamber (18) from a first position closing a recirculation groove (48) to a second position opening the recirculation groove to fluid communication with the compressor chamber.
