Abstract
An actuator comprising a housing, a piston movable in the housing, a rod coupled to the piston and movable therewith, and a tubular member mounted in the housing and having a rod extending therethrough. A frangible section retains the tubular member against axial inward movement from a first position in the housing. When an axial inward force of at least a predetermined magnitude is applied to the tubular member, the frangible section ruptures to allow at least a portion of the tubular member to move axially inwardly. Armor is provided for protecting at least a portion of the housing.
