The invention relates to an exhaust-gas turbocharger (1) as well as in particular a guide apparatus (13) for an exhaust-gas turbocharger (1). The guide apparatus (13) can have a ring of guide vanes (8), which are pivotable on a vane bearing ring (12) by vane studs (18). The vane studs (18) can be ea
The invention relates to an exhaust-gas turbocharger (1) as well as in particular a guide apparatus (13) for an exhaust-gas turbocharger (1). The guide apparatus (13) can have a ring of guide vanes (8), which are pivotable on a vane bearing ring (12) by vane studs (18). The vane studs (18) can be each attached to a vane lever (11). The vane levers (11) can have vane-lever-connectors (17, 10, 46, 47), which interact with unison-ring-connectors (16, 10, 57) of a unison ring (9) which is pivotable with respect to the vane bearing ring (12) in a way, that pivoting the unison ring (9) with respect to the vane bearing ring (12) results in a synchronous movement of one or more of the vane levers (11) and guide vanes (8). The unison ring (9) can be radially supported on axial bosses (14) of several vane levers (11).

I claim: 1. An exhaust-gas turbocharger (1) including a guide apparatus (13) with a ring of guide vanes (8) pivoting on a vane bearing ring (12) by vane studs (18), the vane studs (18) each connected with a vane lever (11), the vane levers (11) comprising vane—lever connectors (17, 10, 46, 47), whic
I claim: 1. An exhaust-gas turbocharger (1) including a guide apparatus (13) with a ring of guide vanes (8) pivoting on a vane bearing ring (12) by vane studs (18), the vane studs (18) each connected with a vane lever (11), the vane levers (11) comprising vane—lever connectors (17, 10, 46, 47), which interact with unison ring connectors (16, 10, 57) of a flat unison ring (9) which is pivotable with respect to the vane bearing ring (12) in a way, that pivoting the unison ring (9) with respect to the vane bearing ring (12) results in a synchronous movement of the vane levers (11) and the guide vanes (8), the unison ring (9) being radially supported on axial bosses (14) of one or more of the vane levers (11), wherein of the vane lever connectors comprises a lever stud (17) engaging with a sliding block (10), wherein the unison ring defines a radially oriented recess—(16) for each of the vane lever connectors, wherein each of the sliding blocks (10) is movable with the radially oriented recess (16), and wherein each of the plurality of radially oriented recesses of the unison ring is open towards a radially outward direction, wherein at least three lever studs (17) have a disc (24) which encloses a corresponding sliding block (10) from one side and which abuts the unison ring (9) in proximity to the corresponding recess (16).
