<p>AN IMPROVED VARIABLE FLOW TURBINE An improved variable flow turbine having a turbine housing constructed of a curved section and a volute section. The curved section contains an inlet at one end and is connected to the volute section at the opposite end. Located within the volute section is a turbine rotor having an outlet which is coaxially aligned with the central axis of the volute section. Positioned at the inlet of the curved section is a control valve for regulating the flow of exhaust gases into the housing. Extending inwardly from the control valve is a divider wall which divides the housing into inner and outer passages. The divider wall is constructed such that the cross-sectional flow area of each the passages within the volute section decreases as they approach the turbine rotor. This unique turbine arrangement enables a turbocharger to operate more efficiently over an engine's operating range.</p> |
