ABSTRACT:
In a method and an apparatus for lubricating the bearings of a turbocharger, the coarsely filtered oil flow (2) for the turbocharger (7) is first of all passed through one of two fine filters (12, 15) connected alternately and in the process is filtered to the consistency required by the turbocharger (7). A portion of the finely filtered oil flow (20) is fed as lubricating oil (21) into the bearings (22) of the turbocharger (7), and the other portion is fed as flushing oil (23) into the clean side (14) of the second fine filter (15). Both the lubricating oil (21) and the flushing oil (23) are then drained off into the oil sump (1). If the first fine filter (12) is contaminated, the second fine filter (15) flushed beforehand by means of the finely filtered oil flow (20) is switched to the oil line (10) of the turbocharger (7) and thus takes over the cleaning function of the first fine filter (12). The clogged first fine filter (12) is then cleaned with the flushing oil (23). In this way, all lubricating points are supplied with lubricating oil of suitable consistency with relatively little expenditure terms of operating time and operating media.
