The invention relates to an actuator. More specifically, but not exclusively, an aircraft pitch damper which comprises an actuator. The actuator comprises a first chamber charged with gas and a second chamber charged with gas. An intermediate chamber containing liquid is located between the first chamber and second chamber. A piston rod extends towards the first chamber through the second chamber and intermediate chamber. A first piston head is associated with and partially defines the first chamber, and a second piston head is associated with and partially defines the second chamber. The piston rod is arranged to abut and move with the first piston head in a first direction, the piston rod further arranged to abut and move with the second piston head in a second direction.
