摘要： A bushing assembly for a reciprocating device is provided. The bushing assembly includes a hollow bushing housing, a collet guide member, and an adjuster mechanism. The hollow bushing housing has a substantially cylindrical shape and an angled inner sidewall. The collet guide member is disposed radially inward from and contacts the angled inner sidewall of the hollow bushing housing. The adjuster mechanism contacts a lower surface of the collet guide member and urges the collet guide member along the angled inner sidewall of the hollow bushing housing.

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.

摘要： A hydraulic hammer may have a housing and a piston configured to reciprocate within the housing. The hydraulic hammer may also have an acceleration channel formed within the housing. The acceleration channel may be configured to receive a pressurized fluid for accelerating the piston in a first direction. The hydraulic hammer may further have a first valve in communication with the acceleration channel. The first valve may be configured to selectively supply a first portion of the pressurized fluid to the acceleration channel. The hydraulic hammer may also have a second valve in communication with the acceleration channel. The second valve may be configured to selectively supply a second portion of the pressurized fluid to the acceleration channel.
