Abstract:
The invention concerns a radial turbo compressor (TCO) including at least one impeller (IP) at least one casing (CS), the impeller (IP) is rotatable about an axis (X), the casing (CS) comprises an inlet (IL) upstream of the impeller (IP), the inlet (IL) comprising an inlet flange (IF) to be mounted to a process gas pipe (PGP), the casing (CS) comprises an outlet (OL) down-stream of the impeller (IP) comprising an outlet flange (OF), the casing (CS) comprises an outlet volute (VL) extending about the axis (X) downstream of the impeller (IP) and upstream of the outlet (OL), and the radial turbo compressor (TCO) comprises a drive unit (DRU) driving the impeller (IP) and being mounted to the casing (CS). In order to simplify exhaust gas quality improvement the invention proposes that the casing (CS) is exclusively supported by the inlet flange (IF) and the outlet flange (OF), the casing (CS) comprises a drive unit flange (DRF), the drive unit (DRU) comprises a fixation flange (FF), the drive unit flange (DRF) and the fixation flange (FF) are fixedly connected to each other by fixation elements (FE), the drive unit (DRU) being exclusively supported by the fixation flange (FF). Further, the invention deals with an arrangement (AR) comprising such a turbo compressor (TCO).

Claim (Index 1):
An arrangement comprising a piston engine (PE), and comprising:\n an exhaust gas line (EGL) for exhaust gas (EG); a recirculation line (RL) conducting a portion of said exhaust gas (EG) into an inlet of said piston engine (PE); wherein a radial turbo compressor (TCO) is provided in said recirculation line (RL), wherein the radial turbo compressor (TCO) comprises:\n at least one impeller (IP), at least one casing (CS); \n wherein said impeller (IP) is rotatable about an axis (X), wherein said casing (CS) comprises an inlet (IL) upstream said impeller (IP), said inlet (IL) comprising an inlet flange (IF) to be mounted to a process gas pipe (PGP); \n said casing (CS) comprising an outlet (OL) downstream of said impeller (IP) comprising an outlet flange (OF); \n wherein said casing (CS) comprises an outlet volute (VL) extending about said axis (X) downstream of said impeller (IP) and upstream of said outlet (OL); \n wherein said radial turbo compressor (TCO) comprises a drive unit (DRU) driving said impeller (IP) and being mounted to said casing (CS), wherein, when in use, said casing (CS) is exclusively supported by said inlet flange (IF) and said outlet flange (OF); \n wherein said casing (CS) comprises a drive unit flange (DRF), wherein said drive unit (DRU) comprises a fixation flange (FF), wherein said drive unit flange (DRF) and said fixation flange (FF) are fixedly connected to each other by fixation elements (FE); and \n wherein said drive unit (DRU) is exclusively supported by said fixation flange (FF), wherein said casing (CS) comprises ribs (RB) in order to increase the bending stiffness of said casing (CS), said ribs (RB) distributed along the circumference of said casing extending axially at least partly between said drive unit flange (DRF) and said inlet flange (IF) and extending in radial direction along a rib's (RB) height.
