Abstract
A valve assembly is provided with a valve body, a valve needle and an armature. An actuator assembly surrounds the valve assembly. The actuator assembly includes a housing and a coil. The coil can be energized so as to induce a force for axially displacing the armature. A flow characteristic of fluid to be injected by the injector is adjusted by axially shifting the valve assembly and the actuator assembly relative to one another.
Claims18
A method of manufacturing an injector for injecting fluid, the method comprising:
- providing a valve assembly having a valve body, a valve needle and an armature, the valve body defining a longitudinal axis and being formed with a cavity configured to receive therein the valve needle and the armature, the valve needle and the armature being mounted for axial movement relative to the valve body and being operable to control an injection of fluid from the cavity to an exterior of the injector;
- providing an actuator assembly surrounding the valve assembly, the actuator assembly including a housing and a coil, the coil being energizeable to induce a force for axially displacing the armature;
- and
- adjusting a flow characteristic of the fluid to be injected by the injector by axially shifting the valve assembly and the actuator assembly relative to one another.

An injector for injecting fluid, the injector comprising:
- a valve assembly having a valve body, a valve needle and an armature, said valve body defining a longitudinal axis and being formed with a cavity configured to receive therein said valve needle and said armature, said valve needle and said armature being mounted for axial movement relative to said valve body and being operable to control a flow rate of injected fluid from the cavity to an exterior of said injector;
- an actuator assembly surrounding said valve assembly, said actuator assembly having a housing and a coil, said coil being energizeable to induce a force for axially displacing the armature;
- and
- wherein said valve assembly and said actuator assembly are shaped and disposed to enable an adjustment of a flow characteristic of fluid to be injected by the injector by axially shifting said valve assembly and said actuator assembly relative to one another during an assembly of the injector.
