Abstract
A gas spring comprising: a cup-shaped body; a movable piston which is inserted in an axially slidable manner in the cup-shaped body and is coupled to the cup-shaped body in a fluid-tight manner, so as to delimit a variable-volume closed chamber adapted to contain a pressurised gas; and a safety plug provided with a shank which extends in pass-through manner in the bottom wall of the cup-shaped body, and protrudes cantilevered within the cup-shaped body so that its distal end can be reached/struck by the movable piston in the case of overtravel; the distal end of the shank having a substantially tubular structure that directly communicates with the closed chamber.
