    • A device for a flushing head (3) of a rock drilling machine (1), which includes a machine housing (3) and, inside a cylinder (18), a to and fro moveable percussive piston (17) arranged to exert percussive action against a shank adapter (15), wherein the shank adapter has symmetry axis (19) and a flushing medium channel (22,23) for co-operation with a flushing medium chamber (24) in the flushing head (3) surrounding the shank adapter (15), said flushing head (3) being provided with a connection unit (7) for the connection to a flushing hose (10). The flushing head (3) and the machine housing (2) exhibit co-operating fastening means and fastening elements (6) in line with a force direction of tensile forces (F) being exerted by the flushing medium hose (10) on the connection unit (7) for movability of the flushing head (3) in respect of the machine housing (2) in directions perpendicular to said symmetry axis (19). The device also concerns a rock drilling machine including such a device.

    • The present invention relates to a hydraulic percussive arrangement comprising a displaceable arrangement (1) in a casing (11), in which casing (11) the following are arranged at the displaceable arrangement (1 ): a first chamber (5) connected to a return line (7) for hydraulic oil, a bushing (6) on a first side of the first chamber (5) and separated from the first chamber (5) by a first gap (12) along the displaceable arrangement (1), and a second chamber (2) with a higher pressure of hydraulic oil than that of the first chamber (5) and arranged on a second side of the first chamber (5), separated from the first chamber (5) by a second gap (4) along the displaceable arrangement (1). According to the invention, a third chamber (8) is fixed arranged between the second gap (4) and the first chamber (5) and the third chamber (8) is connected to the first chamber (5) not only by a first passage (14) but also by a third gap (9) along the displaceable arrangement (1). The invention relates also to a piston guide in such a hydraulic percussive arrangement and to a drilling rig with such a percussive arrangement.
    • 液压冲击装置技术领域本发明涉及一种液压冲击装置,其包括在壳体(11)中的可移动装置(1),其中下列装置布置在可移动装置(1)处:第一腔室(5) 用于液压油的返回管线(7),在第一室(5)的第一侧上的衬套(6),并沿着可移位装置(1)与第一室(5)分隔开第一间隙(12);以及 第二室(2),其具有比第一室(5)更高的液压油压力,并且布置在第一室(5)的第二侧上,与第一室(5)分隔开第二间隙(4) )沿着可移位装置(1)。 根据本发明,第三室(8)固定地设置在第二间隙(4)和第一室(5)之间,第三室(8)不仅通过第一通道 (14),而且沿着可移位装置(1)的第三间隙(9)。 本发明还涉及一种具有这种液压冲击装置的活塞导向件以及具有这种冲击装置的钻机。
