Abstract
An actuator assembly () comprises a body () in which works an actuating piston (), a first piston () and at least one second piston (), a chamber () containing a substantially incompressible fluid by which each of the first and second pistons () acts on the actuating piston (). The movement of the first piston () from a retracted position to an extended position acts via the fluid to cause the actuating piston () to move from a retracted position to an operational position, and subsequent movement of a second piston () from a retracted position to an extended position acts via the fluid to cause an actuation movement of the actuating piston ().
