Beschreibung
Zusammenfassung:	A variable geometry distributor for a turbine, particularly for a motor vehicle turbocharger assembly, comprising: - a first annular element (2), - a second annular element (4), coaxial to said first annular element (2) and with respect to a longitudinal axis (X) of said distributor (1), and mobile with respect to said first annular element (2), wherein: - said first and second annular element (2, 4) comprise, respectively, first and second profiles (14, 46) defining, through their coupling, a plurality of blades (14, 46) separated by openings (V), - a movement of said second annular element (4) with respect to said first annular element (2) determines a variation of geometry (A min , A max ) of said openings (V). The movement of the second annular element (4) with respect to the first annular element (2) is a rotation (DC, DO) around said longitudinal axis (X) which determines the variation of geometry (A min , A max ) of said openings (V).
