Claim:
1. A turbine for an exhaust gas turbocharger with a turbine casing ( 18 ), comprising a housing space for a turbine wheel provided with blades ( 12 ), the turbine casing including radial inlet passages ( 13 ) with guide vanes ( 10 ) which are fixedly arranged upstream of the turbine wheel ( 12 ) in the radial inlet passages ( 13 ) formed between stationary guide walls of the turbine casing ( 18 ) for guiding exhaust gas to the turbine wheel blades ( 12 ), and with actuating elements ( 16 ) by means of which an inlet flow cross-section of the turbine through which the exhaust gas flows is variably adjustable and which are movable in the axial direction of the turbine between a blocking position restricting the flow cross-section and an open position clearing the flow cross-section relative to the turbine casing ( 18 ), the actuating elements ( 16 ) being bolt-like and extending through separate conforming openings formed in the guide walls between the guide vanes ( 10 ) into, and out of, the radial inlet passages ( 13 ) defined between the guide vanes ( 10 ) for controlling the turbine inlet flow passage cross-section.
