Abstract:
1. A turbocharger with variable turbine geometry comprising: a radial gap configured for gas flow; and at least one adjustable guide blade, wherein the guide blade is swivel-mounted on an axially moveable carrier ring having a ring axis, thereby forming a radial wall of the radial gap about at least one swivel axis which is substantially parallel to the ring axis; and wherein the carrier ring is clamped against relatively stationary stops by a thrust spring device, such that the thrust spring device loads the carrier ring within a ring zone configured axially adjacent to the stops; wherein the ring zone is on the side of the carrier ring facing away from the stops; and wherein, during operation, a lateral edge of each of the at least one guide blade tightly follows the radial wall of the radial gap, wherein the thrust spring device is a cantilever spring arrangement having a radially inner ring disc region that is clamped against a housing surface of a bearing housing, wherein a plurality of leaf spring-like radial cantilever arms are arranged in a star-like configuration on a region of the carrier ring, and are clamped against the carrier ring.
