<p>The invention relates to a stop gas spring which avoids the rebound effect, increasing the volume of one of the chambers containing the gas. It comprises a hollow cylinder with a first cylindrical cavity (2) in which a first piston (3) moves, generating an upper chamber (10) and a lower chamber (11), and a second cylindrical cavity (4) in which a second piston (7) moves, the two cavities being separated by an intermediate base (5). The second piston (7) is connected to, or in contact with, third pistons (8) arranged in the intermediate base (5). The invention also comprises a connection element (9) for allowing the introduction and extraction of a gas into or from the second cylindrical cavity (4) in order to move the second piston (7) which moves the third pistons (8), thereby varying the volume of the lower chamber (11).</p> |
