Abstract (en)
A lockable actuator has lock segments that move into recesses inside a piston to enable the piston to move. The lock segments may also move radially outwardly from the recesses in the piston to engage a bevel edge of a cylinder housing assembly to lock the piston. Lock rams having ramps force the lock segments radially outwardly into engagement with the bevel edge of the cylinder housing assembly.
