An automatic shutoff system for a hydraulic hammer is disclosed. The automatic shutoff system may include an inlet groove formed around a piston associated with the hydraulic hammer and configured to receive pressurized fluid, and an outlet groove formed around a piston associated with the hydraulic hammer and configured to discharge the pressurized fluid. The automatic shutoff system may also include an annular passage configured to allow the pressurized fluid to flow between the inlet and outlet grooves. The automatic shutoff system may further include a valve disposed upstream of the inlet groove and configured to selectively block the pressurized fluid from flowing into the inlet groove based on an operational state of the hydraulic hammer. |
