Abstract
A shock absorber comprising a strut (1), a sliding rod (3) mounted to slide inside the strut, at least one gas chamber (13, 17) under pressure, an oil chamber (6) associated with the gas chamber, and an expansion chamber (5) connected to the oil chamber via expansion throttling valve (8), the volume of the expansion chamber (5) varying as a function of the extent to which the sliding rod is received in the strut. The shock absorber also includes an expansion short circuit passage (18) between the oil chamber (6) and the expansion chamber (5), the expansion short circuit passage having a cross-section which is greater than the flow section of throttling valve (8), and the shock absorber includes controlled closure partition (32) for closing expansion short circuit passage (18).
