A percussion power tool assembly (10) comprises a hand-held percussion power tool (11), a chamber (12) mounted on the tool (11), and a fluid reservoir (14) supported independently of the tool (11). The chamber (12) surrounds the body (20) and has a flexible lining (30) defining a bladder which inflates/deflates in sympathy with fluid filling, or emptying from, the chamber. In practice, the deadweight of the tool is reduced to facilitate moving the tool, and is increased when the tool is in use to achieve required reaction force between tool and work piece with reduced contribution from the operator.
La présente invention concerne un ensemble outil mécanique à percussion (10) comprenant un outil mécanique à percussion portatif (11), une chambre (12) montée sur l'outil (11) et une citerne de fluides (14) reposant séparément de l'outil (11). La chambre (12) entoure le corps (20) et possède une conduite flexible (30) formant une vessie qui se gonfle et se dégonfle au gré du remplissage ou de l'évacuation des fluides de la chambre. En pratique, on réduit le poids mort de l'outil pour faciliter son déplacement, puis on l'augmente lors de son utilisation, de manière à obtenir la force de réaction requise entre l'outil est la pièce à usiner, avec allégement de l'intervention de l'opérateur.
