METHOD FOR MANUFACTURING AN INJECTOR FOR INJECTING FLUID AND INJECTOR FOR INJECTING FLUID

摘要

The present invention relates to an injector for injecting a fluid and a manufacturing method thereof. The manufacturing method of an injector for injecting a fluid comprises a step of providing a valve assembly (3) comprising a valve body (7), a valve needle (9) and an armature (11). The method further comprises a step of providing an operational body assembly (5) surrounding the valve assembly (3) and comprising a housing (23) and a coil (21). The coil (21) can conduct electricity to induce a force for axially displacing the armature (11). Moreover, the method comprises a step of adjusting a flow characteristic of a fluid to be injected by the injector by axially shifting the valve assembly (3) and the operational body assembly (5) with respect to each other. An injector (1) is also disclosed.
