摘要： A power tool (1) having a striking means (5), by which a percussive tool (2) that can be driven at least partially along an axis (A) struck directly and having a flushing bore (4) extending at least partially longitudinally through a tool shank (3), and having a flushing head (6) having a radially inwardly open transverse bore hole (8) connected in a flow-through fashion with a fluid channel (7). The flushing head (6) has at least one hollow cylindrical sleeve-like guide surface (9), which is fitted for an insertion end (10) of the striking tool (2). The striking means (5) sealed by a seal (11a, 11b) is cup-like. The striking means (5) is moveably guided and made fluid tight by the seal (11a, 11b) to embrace the machine-side part of the insertion end (10) having the machine-side open flushing bore (4).
摘要翻译：一种具有打击装置（5）的动力工具（1），通过该打击装置可以至少部分地沿轴线（A）驱动的冲击工具（2）直接撞击并具有至少部分纵向延伸的冲洗孔（4）通过工具柄（3），并且具有冲洗头（6），所述冲洗头（6）具有径向向内敞开的横向钻孔（8），流动通道与流体通道（7）连接。冲洗头（6）具有至少一个中空的圆柱形套筒状的引导表面（9），其被安装用于打击工具（2）的插入端（10）。由密封件（11a，11b）密封的打击装置（5）是杯形的。打击装置（5）由密封件（11a，11b）可移动地引导并使其流体密封，以包围具有机器侧开口冲洗孔（4）的插入端（10）的机器侧部分。
