Abstract (en)
[origin: US4565068A] A turbocharger for an internal combustion engine has a turbine casing including an inlet opening from which radially internally and radially external spiral paths extend. These spiral paths have a common partition, and the exhaust gas inlet cross-section of the turbine casing can be varied by a control element for the purpose of adapting the characteristic curve of the turbocharger to different operating ranges of the internal combustion engine. And, the spiral paths are in hydrodynamic communication through orifice areas provided in the partition, with such orifice areas being spaced an equal distance from one another in the direction of flow of the exhaust gas, and the spiral paths extend substantially over the entire peripheral area of the turbine wheel.
