摘要:
A pile hammer includes a cylinder, a piston displaceably guided in the cylinder, and a striker displaceably guided in the cylinder. The striker is disposed underneath the piston in the operating position of the pile hammer. A combustion chamber is delimited axially by a face surface of the striker that lies in the interior of the cylinder and by a face surface of the piston. Using at least one fuel feed device a predetermined amount of fuel can be introduced into the combustion chamber during each work cycle. An end ring is disposed on the cylinder for forming a capture groove. The piston is provided with a step that projects outward, which makes contact with the capture groove in the upper end position of the piston, and the end ring is elastically connected with the cylinder.

桩锤包括气缸,在气缸中可移动地引导的活塞和在气缸中可移动地引导的撞针。 在桩锤的操作位置,撞击器设置在活塞的下方。 燃烧室由位于气缸内部和活塞表面的冲击器的表面轴向限定。 使用至少一个燃料供给装置,可以在每个工作循环期间将预定量的燃料引入燃烧室。 在圆筒上设置端环以形成捕获槽。 活塞具有向外突出的台阶,其在活塞的上端位置与捕获槽接触,并且端环与气缸弹性连接。
