Abstract: An exhaust-gas turbocharger (1) having a compressor (2) which has a compressor housing (3), a turbine (4) which has a turbine housing (5), a bearing housing (6) between the compressor housing (3) and the turbine housing (5), and a control capsule (7) which has a housing (8) on which is provided a retaining device (9) which interacts with a fastening device (10) on the turbocharger in order to fix the control capsule (6) to the compressor housing (3), the turbine housing (5) or the bearing housing (6). The retaining device (9) is arranged on an outer circumferential region (11) of the control capsule (7), and the fastening device (10) fixes the retaining device (9) in a non-positively locking manner.

Abstract: An exhaust-gas turbocharger (1) having a turbine housing (2), having a compressor housing (3), having a bearing housing (4), which has a bearing housing axis (L), and having a connecting device (5), for connecting the bearing housing (4) to the compressor housing (3) and/or the turbine housing (2). The connecting device has a plurality of connecting elements (6) which each have a connecting element end face (7). The number of bores (8) in the compressor housing (3) corresponds to the number of connecting elements (6). The bores (8) and the connecting elements (6) inserted into the bores (8) are arranged at an acute angle (?) with respect to the bearing housing axis (L), and the connecting element end faces (7) rest on an associated bearing surface (9) of the bearing housing (4) and/or turbine housing (2).

Abstract: The invention relates to a bearing housing body group (1) of an exhaust-gas turbocharger, having a housing (2) for a bearing arrangement of a rotor shaft (3); having a turbine wheel (4) on one end (5) of the rotor shaft (3); having a compressor wheel (6) on the opposite end (7) of the rotor shaft (3); and having a compressor-wheel-side housing cover (8) which can be fixed by means of a fastening device (9) in a compressor-wheel-side housing opening (10), wherein the fastening device (9) is designed as a bayonet connection.
