Abstract
In an exhaust turbocharger for an internal combustion engine including a turbine and a compressor, which is driven by the turbine, wherein the compressor comprises a compressor impeller in a flow duct, a transfer component with flow passages extends radially around the compressor impeller in the axial direction of the impeller and provides for communication with the flow duct. To provide for variable adjustment of the effective flow cross-section of the transfer duct, a transfer ring is provided which comprises two component rings, which are rotatable relative to one another.
Claims9
A compressor for an exhaust turbocharger of an internal combustion engine, said compressor being a radial compressor and including a housing with an axial inlet area and a radial outlet area, a compressor impeller disposed in a compressor flow duct of said housing, a transfer component extending around the compressor inlet area of said impeller and including two component rings with transfer slots arranged directly adjacent said impeller and being open toward said impeller over their full axial length so as to be in communication with the compressor flow duct, said component rings being rotatable relative to each other for adjustment of the effective axial flow cross-section of said flow slots between an aligned overlapping position, in which the transfer slots in the two component rings are in alignment, and a blocking position, in which the transfer slots in the component rings are at least partially out of alignment.
