摘要: A pneumatic percussive tool has a barrel in which is inserted a hammer piston imparting blows at a working tool at regular intervals. A floating sleeve surrounding the working tool is provided in the front end portion of the barrel, the sleeve having a projection defining with a barrel groove a damping chamber communicating with a source of compressed gas. There is provided a shell rigidly secured to the barrel, which surrounds the sleeve so as to define in the zone of its projection an auxiliary damping chamber communicating with the source of compressed gas when the sleeve is in its lower position.
