摘要： The invention relates to a hydraulically operated impact device, such as a percussion hammer or some other breaking apparatus, comprising a control valve (6) for controlling pressure fluid supplied to and from the percussion piston (1) so that the direction of motion of the piston (1) can be changed in accordance with the cycle of operation of the impact device. According to the inventive idea, when the control valve (6) is in the impact position, the impact device is provided with a closed space that is partly bordered by the control valve and the percussion piston. The percussion piston (1) comprises a section which communicates with said space and which has a larger diameter than the upper end of the piston. The control valve and the percussion piston are thus able to move in the same direction until a connection is opened from this closed space to the upper end of the percussion piston (1).

摘要： The invention relates to a hydraulic impact hammer, comprising a protective casing made of two side plates, and provided with attenuation elements for eliminating the noise and vibration caused by the impact hammer. According to the invention, the attenuation elements (5, 6) are arranged in the side plates (1, 2) of the protective casing, so that the attenuation elements (5, 6) can be compressed in at least three directions (X, Y, Z) of the housing (4) while fastening the side plates (1, 2) to each other.

摘要： A breaking apparatus, which comprises a percussion device (1), and in the extension thereof, a tool (3) to which a percussion piston (2) belonging to a percussion device delivers impacts. In the axial direction, the movement of the tool is limited by a stopper element (15) if the movement of the tool exceeds a predetermined range of movement (B) in the direction of the impact (A). The stopper element (15) is a piece made of elastic material, which is arranged in a space between the tool and a supporting surface (16). During the stopping of the tool, the capacity of the space for the stopper element reduces, whereby the element is subjected to pressing. By the effect of the tool movement, the stopper element thus rotates about its cross-sectional central axis (21) and at the same time changes its cross-sectional shape in the reducing space. The invention further relates to a tool used in the above-described breaking apparatus.
摘要翻译：一种破碎装置，其包括冲击装置（1），并且在其延伸部分中，属于冲击装置的冲击活塞（2）向其施加冲击的工具（3）。如果工具的运动在冲击方向（A）上超过预定的运动范围（B），则在轴向方向上，工具的移动受到止动元件（15）的限制。止动元件（15）是由弹性材料制成的件，其被布置在工具和支撑表面（16）之间的空间中。在工具停止期间，用于止动件的空间的容量减小，由此元件受到压力。通过工具运动的作用，止动元件因此绕其横截面中心轴线（21）旋转，同时在减小空间中改变其横截面形状。本发明还涉及在上述断开装置中使用的工具。

摘要： The invention relates to an arrangement in connection with a hydraulically operated impact device, such as a breaking apparatus. The impact device includes a percussion piston, conduits 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. It consists of sleeve-shaped pressure chambers that are separated by a sleeve-like diaphragm arranged between a frame and a sleeve. The pressure chambers are formed such that the inner circumference of the sleeve placed around the frame and the outer circumference of the frame are provided with recesses opposite one another.
