Abstract
A vane ring assembly which includes a lower vane ring (23), an upper vane ring (31), one or more guide vanes (80) positioned at least partially between the vane rings, and a plurality of spacers (49, 50 or 59) positioned between the lower and upper vane rings (23, 31) for maintaining a distance between the lower and upper vane rings, the vane ring assembly being retained in a turbine housing (102) by a retaining ring (400) which is located in a groove (510) in the turbine housing.

A turbocharger comprising
- a turbine housing having at least one recess (510) adapted to receiving an axially expandable elastic retaining member (400, 600),
- vane ring assembly comprising a lower vane ring (23), a upper vane ring (31), and one or more guide vanes (80) pivotably positioned at least partially between said lower and upper vane rings, and at least one spacer (49, 50, 59) positioned between said lower and upper vane rings (23, 31) for maintaining an axial space between said lower and upper vane rings (23, 31), and
- an axially expandable elastic retaining member (400, 600) cooperating with said recess in said turbine housing for axially locating said vane ring assembly in said turbine housing.
A method for assembling a turbocharger, said turbocharger comprising a turbine housing having at least one recess (510) adapted to receiving an axially expandable elastic retaining member (400, 600), and vane ring assembly comprising a lower vane ring (23), a upper vane ring (31), and one or more guide vanes (80) pivotably positioned at least partially between said lower and upper vane rings, and at least one spacer (49, 50, 59) positioned between said lower and upper vane rings (23, 31) for maintaining an axial space between said lower and upper vane rings (23, 31), said method comprising:
- sliding said vane ring assembly into said turbine housing, and
- inserting an axially expandable elastic retaining member (400, 600) into said recess (510) in said turbine housing thereby axially locating said vane ring assembly in said turbine housing.
