Nozzle clamping nut for injection valves and method for producing said nozzle clamping nut

A nozzle clamping nut for an injection valve comprises two sections in the longitudinal direction, having different-sized free inner diameters (D1, D2). A shoulder forms a bearing surface (9) in a transition region between the first and second sections, extending in a circular manner perpendicularly...

Beschreibung
Zusammenfassung:	A nozzle clamping nut for an injection valve comprises two sections in the longitudinal direction, having different-sized free inner diameters (D1, D2). A shoulder forms a bearing surface (9) 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 (3) and an outer tube (1) which have different-sized inner diameters (D1, D2), which fit inside each other and which are connected to each other in a fixed manner, and the bearing surface (9) is formed by the annular front surface of the inner tube (3).
