(4) How does one Hydraulic Breaker Hammer work?
1. The kinetic energy of the hydraulic oil and the kinetic energy
of the accumulator push the cylinder rod upward
to compress the nitrogen chamber,
2. After pushing to the highest point, the reversing valve switches
the direction,
3. The kinetic energy of hydraulic oil and the kinetic energy of
nitrogen compression pushes the cylinder rod down quickly
to strike the drill rod
4. Complete the crushing work.
