Percussive power tool with flushing head

A power tool, comprising striking means (5) for directly striking a percussive tool (2) at least partially displaceable along an axis (A) and having a flushing bore (4) extending at least partially longitudinally through a shank (3) thereof and open at a power tool side thereof and an insertion end (10), the flushing bore (4) opening at a power tool-side thereof at the insertion end (10);

• a flushing head (16) having a fluid channel (7) for feeding flushing fluid thereto, at least one, opening radially inwardly, transverse borehole (8) connected in a flow-through fashion with the fluid channel (7), and at least one hollow cylinder-shaped, guide surface (9) for fittingly receiving an insertion end (10) of the percussive tool (2);
• and at least one seal (11a, 11b) for insuring a flowtight displacement of the striking means (5), the striking means (5) being formed as a cup-shaped member for flowtightly embracing a power tool-side of the insertion end (10) together with a power tool-side opening of the flushing bore (4),
• wherein the striking means (5) extends axially into the flushing head (6) on a percussive-tool side thereof,
• wherein the power tool further comprises a flushing seal (14) arranged between the flushing head (6) and the striking means (5), and wherein the flushing head (6) has a leakage opening (15) opening outwardly relative to a leakage space (16) provided on a power tool-side side of the flushing seal (14).
