摘要:
An injection valve has an injector housing (1) and an actuator and also a nozzle assembly. The nozzle assembly has a nozzle body (6) with a recess (8) into which a nozzle needle (10) is introduced and at one axial end of which an injection nozzle (12) is embodied. The recess (8) has, axially adjacent to the injection nozzle (12), a first guide region (14) for the nozzle needle (10). The recess (8) also has at least one cross-sectional extension which extends toward the other axial end. The recess (8) is embodied for the purpose of delivering fluid to the injection nozzle (12). A guide bushing (20) is introduced into the recess (8) in a subsection of the cross-sectional extension, the guide bushing (20) forming a second guide region (22) for the nozzle needle (10) and being embodied for conducting fuel radially outside of the second guide region (22).
