(3) How does one Hydraulic Rock Breaker 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.
