Abstract

An actuator comprises a cylinder 2 within which are a piston 1, a piston rod 7 and a mechanical linkage arranged to transmit axial movement of the piston to the piston rod at a relative speed which decreases as the piston nears the end of its travel towards the piston rod. A rigid member 14 is pivoted to the piston rod at a first pivot point. A link 17 is pivoted at a second pivot point 18 to the member 14 and at its top end is pivoted at 19 to the piston 1. A pin 23 supported in the cylinder for transverse sliding movement is pivoted to or (as shown) pivotally engageable with the member 14 at a third pivot point. When the piston is at the far end of its travel from the piston rod the second and third pivot points respectively constituted by the pivot 18 and the pin 23 are both on the same side of the piston axis, whereas when the piston moves towards the piston rod, the second pivot point moves to the other side of the piston axis. <IMAGE>
