Title:
COST REDUCED VARIABLE GEOMETRY TURBOCHARGER WITH STAMPED ADJUSTMENT RING ASSEMBLY
Document Type and Number:
WIPO Patent Application WO/2011/109198
Kind Code:
A3
Abstract:
A variable geometry turbocharger is simplified yet able to reliably operate in a robust, cost effective manner. The adjusting ring assembly has a reduced number of parts in the vane adjusting assembly but still operates as it did with the parts in the conventional assembly, but at lower part and capital cost. The adjusting ring is constrained axially and radially by interaction with an inner diameter and an abutment provided in the upper vane ring of the vane pack.
