Patent ID: 7484569

Claim:
A pulse tool ( 1 ), in particular a pulse nutsetter, comprising: at least one pneumatic drive unit ( 2 ), having a drive rotor ( 3 ), and a pulse unit ( 4 ) driven by the drive unit, wherein the drive unit ( 2 ) is assigned a deceleration-dependent inertial cut-off device ( 5 ) for the interruption of an air feed on reaching a cut-off pulse wherein the inertial cut-off device ( 5 ) has at least one cut-off piston ( 8 ), which is movable between an open and a closed position ( 7 ) relative to the drive rotor ( 3 ) for changing the air feed; and a substantially annular inertial body ( 9 ) rotatable by the drive rotor ( 3 ) and upon reaching the cut-off pulse at least one drive body ( 11 ), is adjustable radially relative to the drive rotor ( 3 ) and is deflected by means of an internal contour ( 10 ) of the inertial body ( 9 ), said drive body being movably connected to a release device ( 13 ) movable between a release and a retaining position ( 12 ), for the cut-off piston ( 8 ), wherein the release device ( 13 ) is movable by the drive body ( 11 ) into the release position for the release of the cut-off piston ( 8 ) for movement into its closed position.
