Abstract
Improved cleaning of the nozzle ring and the moving blades of the axial turbine of a turbocharger is to provided by a cleaning device. The cleaning device (20) includes only one nozzle (21, 44) having at least one injection opening (24) as well as a cleaning-agent feed line (23). The injection opening (24) is arranged at any point (38) of an imaginary circular area (34), which in turn is defined by a center (33) arranged at a distance A upstream of the inner casing wall (11) as well as by a diameter d.sub.k. The center (33) lies on an imaginary parallel area (34) formed at a distance A from the inner casing wall (11). The distance A corresponds to the average diameter of the nozzle ring (8) multiplied by a percentage P.sub.1, (5%.ltoreq.P.sub.1 .ltoreq.30%). The center (33) lies at an intersection point (36) of the parallel area (35) and die flow line (17) intersecting the latter at right angles. The diameter d.sub.k of the circular area (34) is likewise dependent upon the average diameter of the nozzle ring (8), which is multiplied by a percentage P.sub.2 (0%.ltoreq.P.sub.2 .ltoreq.6%). The injection opening (24) of the nozzle (21, 44) is oriented at least approximately parallel to the tangential plane (37).
