Simplified variable geometry turbocharger with vane rings

The flow path of exhaust gas to the turbine wheel (70) of a turbocharger is influenced by relative motion between two rings of vanes, at least one of which being provided on a vane ring. The outer ring of vanes contains a plurality of vanes (92, 122), the inner ring of vanes contains a plurality of...

Beschreibung
Zusammenfassung:	The flow path of exhaust gas to the turbine wheel (70) of a turbocharger is influenced by relative motion between two rings of vanes, at least one of which being provided on a vane ring. The outer ring of vanes contains a plurality of vanes (92, 122), the inner ring of vanes contains a plurality of vanes (93, 121), and the inner and outer vanes in registry forming a single generic vane shape. The aerodynamic effect of relative displacement of the outer ring of vanes to the inner ring of vanes produces a modulate-able control of exhaust flow to the turbine wheel.
