Abstract
A movable axial element for a damping system includes a rectilinear absorbent mass positionable in the housing and having at least one annular groove arranged on a periphery of the absorbent mass and in which at least one elastic element is arranged to bear against an internal wall of the housing. The at least one groove includes a base formed by a shoulder of the absorbent mass. An edge formed by a structure bearing an annular lip is mounted in a sliding manner on at least one part of the shoulder along at least one axis of the movable element to form an adjusting device integrated into the movable element to enable the control of a prestressing exerted by the annular lip on the elastic element mounted on the periphery of the absorbent mass, the prestressing being generated without rotation of the annular lip relative to elastic element.
