Zusammenfassung:	A variable damping system (122) for a power cell (118) of a hydraulic hammer (102) is disclosed. The hydraulic hammer (102) has a housing (116) and a mounting bracket (110) disposed on a top side of the housing (120). The variable damping system (122) includes an expandable bladder (124) that is positioned between the power cell (118) and an underside of the mounting bracket (126). The expandable bladder (124) is configured to receive a supply of pressurized fluid and maintain a pre-determined volume of pressurized fluid therein. L'invention concerne un système d'amortissement variable (122) pour une cellule de puissance (118) d'un marteau hydraulique (102). Le marteau hydraulique (102) a un boîtier (116) et un support de montage (110) disposé sur un côté supérieur du boîtier (120). Le système d'amortissement variable (122) comprend une vessie expansible (124) qui est positionnée entre la cellule de puissance (118) et un côté inférieur du support de montage (126). La vessie expansible (124) est configurée pour recevoir une alimentation en fluide mis sous pression et maintenir un volume prédéterminé de fluide mis sous pression à l'intérieur de cette dernière.
