Abstract (en)

[origin: EP0103555A1] A pressure fluid actuated piston-cylinder device including a piston rod locking mechanism which comprises conical wedge means (18, 19) by which a friction grip is accomplished on the piston rod, and a spring (20) arranged to continuously develope an activation load upon the wedge means (18, 19). The locking mechanism also comprises a release piston (29) and a number of levers (27) connecting the release piston (29) to the wedge means (18, 19), thereby amplifying the force developed by the release piston (29). By the lever arrangement a relatively small piston is able to neutralize the force of a powerful activating spring.
