摘要

This disclosure relates to an arrangement (10) for variably adjusting the cross-section of a compressor inlet. Furthermore, the invention relates to a charging device having such an arrangement (10). The arrangement (10) comprises a compressor housing (100) with a main body (140) and an inlet cover (120). The inlet cover (120) defines a compressor inlet (110). The arrangement (10) further comprises an adjustment mechanism (200) which is arranged in the compressor housing (100). The adjustment mechanism (200) comprises an actuation ring (210) and a plurality of orifice elements (220). Each orifice element (220) is coupled to the actuation ring (210) via a respective coupling element (230) and is rotatably supported in the compressor housing (100) via a respective shaft (240). Furthermore, the arrangement (10) comprises at least one wear reducing feature providing a wear reduced operation of the adjustment mechanism (200).
