摘要： Method of manufacturing a hydraulic hammer using a male gauge (10) and a female gauge (8) wherein the hammer comprises a body (2) and a chuck housing (5) that are connectable by means of cooperatively formed thread fittings. In particular, the method uses a cooperatively threaded male gauge (10) and female gauge (8) to form the threads on the body (2) and the chuck housing (5) and to determine the rotational orientation of the body (2) and the chuck housing (5) relative to one another. One of the male gauge (10) and the female gauge (8) is used to measure distortion of the chuck housing (5) caused by heat treatment subsequent to the formation of the thread fitting and thereby to determine the required subsequent machining of the chuck housing (5) necessary to retain the appropriate relative rotational orientation when the chuck housing (5) is connected to the body (2). The method may comprise the steps of making and appropriately marking the male gauge (10) and the female gauge (8)

摘要： A pressure protection valve is provided which provides a fluid short circuit between a fluid pressure inlet of a hydraulic tool such as a hydraulic hammer and a low pressure region when the pressure at the fluid pressure inlet exceeds a first trigger pressure equal to a predetermined permissible pressure. This prevents damage to the hydraulic tool which can arise through operation at excessive fluid flow or pressure from hydraulic fluid supplied by a carrier vehicle. The pressure protection valve may maintain fluid communication between the fluid pressure inlet and the low pressure region until the pressure at the fluid pressure inlet reduces to a pressure below a predetermined second trigger pressure which is less than the first trigger pressure, to prevent further operation of the tool until the flow of fluid to the fluid pressure inlet has been stopped by an operator.

摘要： Rock drilling machine (10) comprising a piston that is arranged to move back and forth in a chamber (12a, 12b) when the rock drilling machine (10) is in use, a cavitation-sensitive component (14), and an oil channel that is arranged to extend between the chamber (12a, 12b) and said cavitation-sensitive component (14). The oil channel comprises a series of restrictions (18) and oil volumes (20) to hinder the movement of cavitation bubbles through said oil channel.

摘要： The invention relates to an impulse generator for a rock breaking tool, the impulse generator (2) comprising a main chamber (4) for receiving a first pressurizeable fluid volume (6), an in the main chamber (4) received impulse piston (8) which is arranged for transfer of pressure energy in the fluid volume (6) into impulses in the tool (10), and a on the side opposite the main chamber (4) side of the impulse piston (8) situated prepressurizing chamber (12) for receiving a second pressurizeable fluid volume (14), where the impulse generator (2) further comprises a on the side opposite the main chamber (4) side of the impulse piston (8) situated pressure relief chamber (16) for receiving a third pressurizeable fluid volume (18), where the relationship between the pressurizing pressures in the fluid volumes (6,14,18) and the rela¬ tions between the areas of the impulse piston (8) facing the chambers (4,12,16) are such that pressurizing of at least the prepressurizing chamber (12) displaces the impulse piston (8) in the direction towards the main chamber (4) and the pressure in the main chamber (4) effects a pressure increase in the pressure relief chamber (16) when the prepressurizing chamber (12) is depressurized, whereby the depressurizing rate in the pressure relief chamber (16) and the velocity of the then transferred pressure impulse into the tool (10) are increased (12). The invention also relates to a hydraulic tool comprising an impulse generator (2), and a method for generation of impulses in a rock breaking tool.

摘要： A hammer (90) is supported in a valving sleeve (82) fixed in an internal passageway (27) of a body (25). The sleeve has a cross wall (81) with an orifice (120) closed and opened by the hammer (90) on one side and a tubular reciprocable valve (60). An annular chamber (58) is formed around the reciprocable valve (60). A piston (51) is mounted in the annular chamber forming a pressurized gas chamber (58) on one side and a high pressure hydraulic oil chamber (75) on the other side. When hydraulic oil is introduced into the oil chamber (75), the reciprocable valve (60) will close the orifice (120) and as the piston (51) moves to compress the gas in the gas chamber (58), it moves the reciprocable valve (60) away from the orifice (120). The high pressure oil discharges against the hammer (90), which strikes a striking tool (102).
