Supercharger for lifting cylinder internal combustion engine of passenger car, has lid element partially fastened at housing of radial-flow turbine by rigid attachment elements that are retained in lid element and in turbine housing

摘要

The supercharger (10) has a guide device (24) including a lid element (28) and a carrier element (26) that are spaced apart from each other in an axial direction to form a flow channel (20) between the lid element and the carrier element. Guide vanes of the guide device are movably arranged at the carrier element relative to the carrier element such that an exhaust gas flowing through the flow channel is derivable by the guide vanes. The lid element is partially fastened at a housing (14) of a radial-flow turbine (12) by rigid attachment elements retained in the lid element and in the housing. The rigid attachment elements consist of a bolt (32) and a screw.
