    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.
