Abstract

The gas cylinder is of the type used for example in punching installations or tools, and comprises two hermetic and independent chambers (7) and (8), the first placed axially to the corresponding rod (6) and the latter placed annularly and externally, with said two chambers externally communicated through branches (16) and (17) which end in a common chamber (14) of a pressure accumulator (11), in which is defined a second chamber (13) which can be charged with nitrogen and is provided with a movable piston (12) for the filling and corresponding pressure balancing between chambers (14), (7) and (8). Ana electrovalve (18) can be closed at will after attaining the pressure balance between said three chambers (14), (7) and (8), preventing rod (6) from recovering its original position after the force exerted on it during operation ceases. <IMAGE>
