Abstract
An electromagnetic actuator assembly for a fluid injection valve includes a first coil and a second coil, which are configured for moving an armature, and an electrical connection circuit for connecting the first and second coils to a power supply. The electrical connection circuit is configured to energize the first coil without energizing the second coil in a first operating mode of the actuator assembly and to energize both the first coil and the second coil in a second operating mode of the actuator assembly.
