    摘要： The invention relates to an impact mechanism comprising a housing (32) with at least two stroke adjustment channels (18, 19, 20); an adjustment arrangement (31) with at least two adjustment pin channels (35, 36, 37, 135, 136, 137) arranged to interact in a manner that can be selected with the stroke adjustment channels (18, 19, 20); and a hammer piston (1) that performs reciprocating motion in the housing (32) in order to impact repetitively onto an anvil (2), which hammer piston (1 ) has a stroke length that can be selected with the aid of adjustment pin channels (35, 36, 37, 135, 136, 137) and the stroke adjustment channels (18, 19, 20). According to the invention, the adjustment arrangement (31 ) comprises an elastic element (48) arranged to maintain the adjustment arrangement (31) in place for the stroke length that has been selected; and an operating means (34) arranged to select adjustment pin channel (35, 36, 37, 135, 136, 137) and thus the stroke length of the hammer piston (1).

    摘要： A percussion device (5) for a rock drilling machine (1) including a percussive piston (6; 15) which is reciprocally movable inside a cylinder and an impact receiving element (7;16) with an impact surface (A;A' ), against which the percussive piston is arranged to perform strikes in an impact direction for transferring of percussive energy through Shockwaves to a percussive tool. The percussion device is distinguished by the impact receiving element (7; 16) including a Shockwave modifying portion (9; 17) which extends in a direction opposite to the impact direction as seen from a plane (P; P') through the impact surface (A; A'). The invention also concerns a rock drilling machine and a rock drilling rig.

    摘要翻译： 一种用于凿岩机（1）的冲击装置（5），其包括可在气缸内往复运动的冲击活塞（6; 15）和具有冲击表面（A; A'）的冲击接收元件（7; 16） ，冲击活塞布置成沿冲击方向进行冲击，以将冲击能量通过冲击波传递到冲击工具。 冲击装置的特征在于包括冲击波修正部分（9; 17）的冲击接收元件（7; 16），该冲击波修正部分沿与冲击方向相反的方向延伸，如从平面（P; P'）看穿过冲击表面 （A; A'）。 本发明还涉及凿岩机和岩石钻机。

    摘要： A water hammer using a drive rod is provided. The water hammer includes a tubular main body having a hollow portion; a socket coupled to an upper end of the main body and having a water pressure supply passage; a cylindrical piston housing connected to the main body; a piston slidably installed in the piston housing, for striking a bit of a bit unit installed at a lower portion of the main body, having a hollow portion through which water is discharged, an annular pressurizing portion protruding on its outer circumferential surface, and a first communication hole connected to the hollow portion; a sliding member fitted into the main body to be coupled to the piston housing, defining a valve installation space, and creating a space portion in which the piston is received when the piston is elevated; a valve member defining the valve installation space into first and third space portions along the length of the piston, the first and second space portions having different cross-sectional areas from each other, and valve member forming a second space portion between the first and third space portions, connected to the hollow portion of the piston and connected to the first space portion when the piston is elevated; and a water pressure supply unit for supplying high pressure water delivered to the water pressure supply passage of the socket to the first and second space portions.
