Abstract
An air-spring percussive tool comprises a casing (1) in which are accommodated a drive (2), a working tool (3), a cylinder (4) having air replenishing ports (11, 12, 13, 14). The cylinder (4) accommodates a piston (5) connected to the drive (2) and a hammer piston (6). The air-spring percussive tool also has a sleeve (17) surrounding the cylinder (4) and having an element for selectively uncovering the air replenishing ports (11, 12, 14) of the cylinder (4) when the sleeve (17) is displaced. The replenishing air ports (11, 12, 14) are disposed in one and the same plane drawn at right angles to the axis of the cylinder (4). <IMAGE>
