Abstract: 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.

Abstract: Lubrication system includes a drive fluid valve member and a detune valve member. The drive fluid valve member is movable from a first to a second position in response to drive fluid pressure to reduce the volume of a variable volume lubricant charge chamber. The detune valve member is movable from a first to a second position in response to lubricant pressure within the lubricant charge chamber, and is adapted to permit fluid communication between inlet and bypass fluid passages in its the first position and to disengage the fluid connection in its second position.

Abstract: A hammer assembly including a hammer housing and a work tool movably supported in the hammer housing is provided. A gas chamber is defined in the hammer housing and contains a compressible gas. An accumulator assembly includes an interior space. A barrier divides the interior space into a first interior portion containing a compressible gas and a second interior portion configured to receive a pressurized fluid. The barrier is configured to be movable in response to changing the amount of pressurized fluid in the second interior portion and such that movement of the barrier varies the volume of the first interior portion. The first interior portion is in communication with the gas chamber. A control valve assembly is configured for selectively placing the second interior portion of the accumulator assembly in communication with a pressurized fluid source.
