Abstract (en)
[origin: EP1467088A1] The invention describes an injection valve (1) with a valve closing element (4) that is biased by a spring (10) against a valve seat (5). The spring (10) is preloaded by an adjusting tube (14) that is arranged within an inlet tube (7) and connected to the inlet tube (7). The invention proposes a retaining element (12,13) that is fixed with the inlet tube (7) and that retains the adjusting tube (14). The retaining element (12,13) blocks a movement of the adjusting tube (14) of the spring (10) and enables an incremental movement of the adjusting tube (14) towards the spring (10). The injection valve (1) shows the advantage that the tension of the spring (10) can be precisely adjusted. <IMAGE>
