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. At least one lubricant dispenser for conveying a lubricant between piston and cylinder is set up in such a manner that conveying of lubricant is brought about via the impact shock of the piston.
摘要(中):
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。 用于在活塞和气缸之间输送润滑剂的至少一个润滑剂分配器被设置成使得润滑剂的输送通过活塞的冲击冲击而产生。
