    摘要: A hydraulic accumulator including an energy storage apparatus with a first piston face configured to reversibly compress an energy storage medium and a second piston face forming at least part of an inner surface of a corresponding second fluid chamber reversibly expandable by movement of the second piston face. A third piston face forms at least part of an inner surface of a corresponding third fluid chamber reversibly expandable by the third piston face. The first, second and third piston faces are coupled together.

    摘要: A hydraulic impact mechanism comprises a housing (10) with a cylinder bore (11) , a forward working chamber (23) and a rear working chamber (18) , a hydraulic fluid supply passage (26) continuously connected to the forward working chamber (23) and a drain passage (33) connected to the rear working chamber (18) , a hammer piston (12) reciprocally guided in the cylinder bore (11) for delivering hammer blows to a working implement (14) attached to the housing (10) , a pressure accumulator (27) pre-loaded to a certain pressure level, and a distribution valve (30) for alternatingly connecting the rear working chamber (18) to the supply passage (26) and the drain passage (33) to thereby reciprocate the hammer piston (12) , wherein a sequence valve (34) is provided in the drain passage (33) with the purpose to keep up the pressure in the rear working chamber (18) to such a level that the resulting forward directed force will prevent the piston (12) from being moved backwards in the cylinder bore (11) at pressure levels in the supply passage (26) below the pre-load pressure level of the accumulator (27).

    摘要: 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).

    摘要: The invention relates to an arrangement in connection with a hydraulically operated impact device, such as a breaking apparatus, the impact device comprising a percussion piston (2), means for feeding pressure fluid into and out of the impact device, and a pressure accumulator. According to the inventive idea, the pressure accumulator is formed as an annular structure surrounding the percussion piston (2). It consists of sleeve-shaped pressure chambers (6a, 6b) that are separated by a sleeve-like diaphragm (11) arranged between a frame (5) and a sleeve (9). The pressure chambers (6a) and (6b) are formed such that the inner circumference of the sleeve (9) placed around the frame and the outer circumference of the frame (5) are provided with recesses opposite one another.
