Abstract: A supercharger device, including, at least one of a variable turbine and a compressor geometry; a guide vane device arranged in a housing, wherein the guide vane device includes at least one vane mounting ring; at least one guide vane is at least one of rotatably mounted thereon the vane mounting ring and rotatably mounted therein the vane mounting ring; and an adjusting ring arranged coaxially to the vane mounting ring and mounted on the latter, which is rotated relative to the vane mounting ring.

Abstract: An exhaust-driven turbocharger for a motor vehicle includes at least one of a variable turbine and a compressor geometry, a vane-mounting ring with guide vanes mounted rotatably thereon and a guide vane cage. The guide vane cage forms at least part of a flow duct and at the same time a mount for the vane-mounting ring. The guide vane cage is supported by spacer elements while creating an axial gap on a housing of the exhaust-driven turbocharger such that hot gas selectively flows behind the guide vane cage. Also, the guide vane cage is clamped between the turbine housing and the mounting housing of the exhaust-driven turbocharger without fixedly connecting the guide vane cage to either one of the two housings.

Abstract: An exhaust-driven turbocharger for a motor vehicle may include a bearing housing and a turbine housing, which are mounted in the bearing house by means of a common shaft. A guide vane cage surrounds the turbine wheel. The guide vane cage may have at least two arms. The arms may be used to help secure the guide vane cage between the bearing housing and the turbine housing such that it can move in the radial direction.
