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.
Claims9
A flow guide structure for an exhaust gas turbine of a turbocharger, comprising a support housing (27), a rotor (13) rotatably supported in the support housing (27) a spiral housing (11) mounted to the support housing (27) and a contoured casing (18) axially movably supported by the spiral housing so as to extend around the rotor (13) and delimiting a flow path through the rotor with a predetermined clearance, the flow guide structure including a support ring (22) supported by a spacer element (20) in spaced relationship from the contoured casing (18) so as to form therebetween a flow path from the spiral housing (11) to the rotor (13), flow guide vanes (19) pivotally supported on the support ring (23) in the flow path for controlling the flow of exhaust gases from the spiral housing (11) to the rotor (13), the support ring being mounted to the support housing (27) by an annular flexible support element (26) which consists of a component of uniform wall thickness.
