Abstract
An actuator having a piston member slideable within a cylinder, the piston member defining with the cylinder a first chamber and a second chamber, the effective cross-sectional of the piston member exposed to the fluid pressure within the first chamber being greater than that exposed to the fluid pressure within the second chamber. The actuator further has first and second ports through which fluid can be supplied to the first and second chambers, respectively, and a third port located intermediate the first and second ports. The piston member and the third port are cooperable to throttle the rate at which fluid is able to escape from the first and second chambers through the third port, in use.
