    • The tool has a guide (4) with bore (11) for the driving piston (1), while at the rear end of the bore is a connecting drilling (7) to a cartridge chamber (6). A base portion (5) encloses the drilling, while the guide is enclosed by a portion (8) of the housing clear of it in the radial direction. The intervening passage (9) so formed is connected to the cartridge chamber and also by a port (10) to the guide bore. A further port (12) in the housing can be shut off, and the passage contains a valve (13) which can be shut, forming an accumulator chamber sealed off from atmospheres and including the driving side of the passage and the guide bore. A distance-piece (2) on the base portion (5) of the guide has a transvers stop face (5) which is of smaller area than the base portion. The piece can alternatively be on the driving piston, and its surface area can be between 0.04 and 0.5 times that of the base portion. its height in the axial direction can be between 0.05 and 0.2 times the piston diam., and its surface (3) can form part of a circle, being typically at the piston edge.
    • 该工具具有用于驱动活塞(1)的具有钻孔(11)的引导件(4),而在钻孔的后端处是与暗室室(6)的连接钻孔(7)。 基部(5)包围钻孔,而引导件由壳体的沿径向方向的一部分(8)封闭。 这样形成的插入通道(9)连接到暗盒室,并且还通过端口(10)连接到引导孔。 在壳体中的另一个端口(12)可以被关闭,并且通道包含可以关闭的阀(13),形成与大气密封并且包括通道的驱动侧和引导孔的存储室。 在导轨的基部(5)上的距离件(2)具有横向止动面(5),该横向止动面的面积小于基部的面积。 该部件可以替代地位于驱动活塞上,其表面积可以是基部的表面积的0.04至0.5倍。 其轴向高度可以在活塞直径的0.05至0.2倍之间,并且其表面(3)可以形成圆形的一部分,通常位于活塞边缘处。
