Patent ID: 8210793

Claim:
A radial compressor for a turbocharger, in particular for an internal combustion engine, with a compressor wheel for conveying and compressing a gas, having an axial intake end and a radial exhaust end, with a compressor wheel space in which the compressor wheel is arranged and which extends from the intake end to the exhaust end, with an inlet port leading to the intake end of the compressor wheel, with at least one recirculation path which opens at one end into the inlet port and at the other end into the compressor wheel space, wherein a control device is provided for modifying a flow-through cross section, namely at least opening and closing the flow-through cross section, of the at least one recirculation path, wherein the control device has a control liner, which is arranged in the inlet port, so it is axially adjustable between an open position and a closed position, and a port liner provided in a stationary position on the housing and borders the inlet port in the area of the control liner and at least partially borders the compressor wheel space on the outside radially, thereby overlapping with a respective radial recess axially and bordering it on the inside radially, wherein the control liner is arranged coaxially with the port liner and the inlet port and is supported on the outside radially on the port liner, so that it is axially adjustable.
