Abstract
A nozzle clamping nut for an injection valve comprises two sections in the longitudinal direction, having different-sized free inner diameters (D, D). A shoulder forms a bearing surface () in a transition region between the first and second sections, extending in a circular manner perpendicularly to the longitudinal direction. The nozzle clamping nut has a large bearing surface with low stress concentration. The nozzle clamping nut consists of an inner tube () and an outer tube () which have different-sized inner diameters (D, D), which fit inside each other and which are connected to each other in a fixed manner, and the bearing surface () is formed by the annular front surface of the inner tube ().
