摘要： An injection valve (16) has an actuator module (4) with a cavity (20) and an actuator unit (14). The injection valve (16) further has a fluid module (2), being disposed at least partially within the cavity (20) of the actuator module (4) and a housing and a valve needle (8). The valve needle (8) is disposed in the housing and is actuatable by the actuator unit (14). The valve needle (8) is operable to prevent a fluid injection in a closing position and permit the fluid injection in further. The actuator module (4) is adhered to the fluid module (2) via a metal adhesive (16), which is arranged between a surface of the housing of the fluid module (2) and a surface of a wall of the cavity (20) of the actuator module (4).
