VARIABLE TURBINE GEOMETRY

A variable turbine geometry (1) may include guide blades (3) mounted rotatably in a blade carrier (2) via one blade bearing pin (4) for each guide blade, a blade lever (5) arranged at an end of the blade bearing pin (4) that faces away from the respective guide blade (3), and an articulated lever (6) for a simultaneous adjustment of the guide blades (3) via an adjusting ring (7) arranged between two adjacent blade levers (5). The articulated lever (6) may be provided with a stop contour (8), and when one of a maximum flow position or a minimum flow position is reached, the stop contour (8) may lie against one of the two adjacent blade levers to define the one of the maximum flow position or the minimum flow position. 本发明涉及种可变几何涡轮(1)，具有：引导叶片(3)，每个引导叶片经由个叶片支承销(4)可旋转地安装在叶片架(2)中；其中，叶片转臂(5)布置在叶片支承销(4)的背向相应引导叶片(3)的端部；铰接转臂(6)，其用于经由调节环(7)同步调节引导叶片(3)，布置于两个相邻叶片转臂(5)之间。此处对本发明来说重要的是，铰接转臂(6)设置有停止轮廓(8)，当达到最大流量位置时，停止轮廓(8)抵靠两个相邻叶片转臂(5)之，从而限定最大流量位置，或者，铰接转臂(6)设置有停止轮廓(16)，当达到最小流量位置时，停止轮廓(16)抵靠两个相邻叶片转臂(5)之，从而限定最小流量位置。
