SELF-CHARGING HYDRAULIC HAMMER

摘要

A self-charging assembly having a first side wall, a second side wall, a third sidewall, a first chamber, a second chamber, a first valve assembly, and a second valve assembly. The second side wall is disposed within the first side wall. The third sidewall connects the first side wall and the second side wall. The first chamber is defined by the first, second, and third sidewalls. The second chamber is disposed within the first chamber and is defined by the second side wall. The first valve assembly is configured to selectively place an interior portion of the second chamber in communication with an atmosphere outside of the self-charging assembly. The second valve assembly is configured to selectively place an interior portion of the first chamber in communication with the interior portion of the second chamber.
