The invention relates to a damping device (1) with power-assisted deceleration, which is intended to be used in the field of hydraulic shock dampers. The inventive device is of the type that comprises a sealed body (10) which is filled with a hydraulic fluid (F) and in which a piston (20) is mounted, said piston being solidly connected to a rod (2) that can be moved axially outside the body (10). According to the invention, the rod (2) and the body (10) are arranged such that, while one is solidly connected to a support, an impact (I) in relation to the other causes the axial movement of the piston (20) and the compression of the fluid (F) in a chamber (16). The invention also comprises: flow means (15) which are designed such as to enable the hydraulic fluid (F) to be released from the chamber (16); and an element (3) which can move axially, under the effect of its own mass, inside the body (10) and which is designed such as to form a check valve that can seal the flow means (15) when pushed back in the opposite direction to that of the impact (I) by an elastic means (30).
Dispositif d'amortisseur (1) à décélération asservie, destiné à être utilisé dans le domaine des amortisseurs de chocs hydrauliques, du type comprenant un corps fermé (10) empli d'un fluide hydraulique (F), dans lequel est monté un piston (20) solidaire d'une tige (2) apte à être déplacée axialement hors du corps (10), la tige (2) et le corps (10) étant agencés en sorte qu'un choc (I) sur l'un, alors que l'autre est solidaire d'un support, provoque le déplacement axial du piston (20) et la compression dudit fluide (F) dans une chambre (16). Il comporte des moyens d'écoulement (15) conçus aptes à permettre une sortie dudit fluide hydraulique (F) hors de la chambre (16), et un élément (3) mobile axialement, sous l'effet de sa masse, dans le corps (10) et conçu apte à former clapet pour obturer les moyens d'écoulement (15) lorsqu'il est repoussé, dans la direction opposée à celle du choc (I), par un moyen élastique (30).
