Abstract (en)
Injector (1) for injecting fluid with an injector body (3), a valve assembly (5) comprising a valve body (9) and a valve needle (11), the valve body (9) having a longitudinal axis (13) and comprising a cavity (15) with a valve seat (17), an electromagnetic actuator assembly (7) comprising an armature (21), a spring chamber (27) located in the cavity (15), being fluid-tightly insulated from an exterior of the spring chamber (27), and a calibration spring (29) for axially biasing the valve needle (11) away from the closing position, being received in the spring chamber (27), being mechanically coupled to the valve needle (11) to bias the valve needle (11) with a first axial end (33) and being fixedly coupled to the injector body (3) with a second axial end (35) such that a position of the second axial end (35) is independent of pressure of fluid in the cavity (15).
