<p>An actuator comprising a motor (1) which comprises a rotatable drive shaft (2), a first spindle (3) which is rotatably arranged to be driven directly or indirectly by the drive shaft (2) of the motor, and a piston rod (4) which is arranged to perform a linear translational movement in an axial direction relative to the first spindle between a first end position and a second end position while the first spindle is rotating. The actuator is characterized in that it furthermore comprises a rotatable second spindle (5) which the drive shaft of the motor is arranged to directly or indirectly drive, wherein the second spindle is arranged to drive the rotation of the first spindle via a carrier (6, 7, 40).</p> |
