Abstract (en)
[origin: WO2022022965A1] A method for installing a fuel injector (1) which comprises a holding body (2) and a nozzle body (4), wherein a clamping shoulder (8) is formed at the transition of the shaft (6) to the nozzle collar (5). The holding body (2) is clamped to the nozzle body (4) by a nozzle-clamping nut (7). For the installation of the fuel injector, an installation tool (16) is pushed over the shaft (6) of the nozzle body (4) as far as a clamping surface (13) of the nozzle body (4). A pretensioning force (Fa) is then exerted on the nozzle body (4) via the installation tool (16) such that the nozzle body (4) is pressed at least indirectly against the holding body (2), and the installation tool (16) clamps the shaft (6) of the nozzle body (4). The nozzle-clamping nut (7) is subsequently screwed onto the holding body (2) until a defined contact pressure of the nozzle body (4) against the holding body (2) is achieved. The clamping tool (16) used has a hollow-cylindrical receptacle (17) for the shaft (6) of a nozzle body (4), and the wall of the cylindrical receptacle (17) is designed in such a manner that it is deformed inwards when a longitudinal force is applied to the clamping tool (16).
