Actuator arrangement and injection valve

摘要

Actuator arrangement (10), comprising a solid state actuator unit (12) with a longitudinal axis (A) comprising electric pins (20) being electrically coupable to a power supply and a piston (18), wherein the solid state actuator unit (12) comprises a first axial end area (24) designed to act as drive side and a second axial end area (26) facing away from the first axial end area (24), a compensator unit (14) being arranged facing the second axial end area (26) of the solid state actuator unit (12) along the longitudinal axis (A) of the solid state actuator unit (12) and being in contact with the solid state actuator unit (12) via the piston (18), and a damping element (16) being designed and arranged in-between the compensator unit (14) and the solid state actuator unit (12) facing the second axial end area (26) of the solid state actuator unit (12), the damping element (16) being preloaded by the compensator unit (14) and the solid state actuator unit (12).
