Abstract (en)

Method for adjusting an injection valve (10), the injection valve (10) comprising a housing (12) including a central longitudinal axis (A), the housing (12) comprising a cavity (24) with a fluid outlet portion (28), a valve needle (22) axially movable in the cavity (24), the valve needle (10) preventing a fluid flow through the fluid outlet portion (44) in a closing position and releasing the fluid flow through the fluid outlet portion (44) in further positions, an actuator unit (16) being coupled to the valve needle (22) and enabling the axial movement of the valve needle (22) relative to the valve body (20) upon actuation of the actuator unit (16), and an adjusting arrangement (14). The adjusting arrangement (14) comprises a spring retaining element (42) being coupable to the housing (12), a thermal compensation unit (40) being coupable to the spring retaining element (42), and an adjusting spring (44) arranged between the thermal compensation unit (40) and the spring retaining element (42) and being enabled to exert an axial preload force on the actuator unit (16).
