Abstract
A low speed high pressure ration turbocharger incorporates a compressor impeller having impeller blades for a first stage of compression mounted on a first side of the wheel and impeller blades for a second stage of compression mounted on a second side of the wheel. Driving the dual sided compressor impeller on a common shaft from the turbine wheel allows reduction in rotational speeds while increasing compression ratio of the turbine. The scroll inlet and outlet volute for the second stage inducer are integrated with the compressor housing or other portions of the turbocharger case for compact packaging.
