<p>A turbocharger made according to this invention has a volute-type housing with a nozzle; a nozzle on the compressor or exhaust side and a flow control gate on the exhaust side. The nozzle is directed to impinge air on demand and under pressure upon the compressor side rotor. The flow control gate is arranged to momentarily pivot on demand between a neutral first position and a closed second position toward the exhaust side rotor. The nozzle may provide air substantially instantaneously as the flow control gate moves into the second position. Further, the nozzle, when arranged on the compressor side, preferably directs air under the gate when the gate is in the second position.</p> |
