    Abstract: A hammer assembly (10) including a hammer housing (12) and a work tool (16) movably supported in the hammer housing is provided. A gas chamber (38) is defined in the hammer housing (12) and contains a compressible gas. An accumulator assembly (40) includes an interior space (44). A barrier (46) divides the interior space into a first interior portion (48) containing a compressible gas and a second interior portion (50) configured to receive a pressurized fluid. The barrier (46) is configured to be movable in response to changing the amount of pressurized fluid in the second interior portion (50) and such that movement of the barrier varies the volume of the first interior portion (48). The first interior portion (48) is in communication with the gas chamber (38). A control valve assembly (54) is configured for selectively placing the second interior portion (50) of the accumulator assembly (40) in communication with a pressurized fluid source.

    Abstract: The invention relates to a pressure-fluid-operated percussion de­vice comprising a frame (2) allowing a tool (13) to be arranged therein movably in its longitudinal direction, means for feeding pressure liquid to the percussion device (1) and for returning pressure liquid to a pressure liquid tank, and means for producing a stress pulse in the tool by utilizing pressure of the pres­sure liquid. The invention includes a pressure liquid source for maintaining pressure in the working pressure chamber (3), and means for intermittently feeding pressure liquid to the percussion device (1) such that the pressure liq­uid pushes a transmission piston into a predetermined backward position such that pressure liquid is discharged from the working pressure chamber (3), and for alternately allowing pressure liquid to be discharged rapidly from the per­cussion device (1) so that the pressure of the pressure liquid in the working pressure chamber (3) and pressure liquid flowing thereto from the pressure liquid source pushes the transmission piston (4) towards the tool (13), thus generating a stress pulse in the tool (13).

    Abstract: A fluid actuated tool in the form of a hydraulic hammer (20) comprises a body (22), a cylinder (26) and a chuck body (28). A piston (34) mounted within the cylinder (26) reciprocates and impacts on a chisel (36). Movement of the piston (34) results from the supply of hydraulic fluid, controlled by an apertured distributor valve sleeve (38) with a number of cylinder ports (40) communicating with a series of axial fluid carrying bores (42). Movement of the piston (34) and the sleeve (38) bring ports (40) and bores (42) into and out of alignment, so regulating movement of the piston (34).
