Charging device

The present invention relates to a charging device (1), preferentially an exhaust gas turbocharger (1') for a combustion engine, with a compressor (2), comprising a compressor wheel (4) which radially displaces axially onflowing fluid, particularly air. Here it is substantial to the invention that an adjusting device (10) is provided, which in a first position exclusively conducts the displayed fluid to a spiral housing (6) of the charging device (1), while the adjusting device (10) in a second position exclusively conducts the air displaced by the compressor wheel (4) into a recirculation channel (12). The invention furthermore relates to a combustion engine having such a charging device (1).
