Abstract: In a flow guide structure for an exhaust gas turbine of a turbocharger including a support ring and a contoured casing which are disposed at a distance from one another by means of spacer elements and between which adjustable guide vanes are rotatably supported, the contoured casing being disposed in a spiral housing so as to be axially displaceable therein and delimiting a lateral outer contour of a rotor with clearance, while the support ring is centered and mounted relative to a support housing of the exhaust gas turbine by means of an annular flexible support element, the support element comprises a component with a uniform wall thickness.

Abstract: In an exhaust gas turbine for a turbocharger with a spiral housing consisting of sheet metal surrounding a guide vane structure and having a tangential inlet funnel and an outer shell which also consists of sheet metal and surrounds the spiral housing with an air gap, the spiral housing and the outer shell are pot-shaped and the ends adjacent the guide vane structure are delimited by parts of the guide vane structure, the spiral housing being connected to these parts by means of at least one axially flexible element.
