    • A valve device (V, 4') for controlling the movement in a machine housing (2) of a reciprocating percussion piston (3) of a percussion device (1) for a rock drilling machine with a first chamber (5) that can be pressurized for forward driving of the percussion piston (3) and a second chamber (8) that can be pressurized for back-driving of the percussion piston (3) , wherein the valve device includes a to and fro movable valve element (20) , the movement of which being controlled as a response to the position of a valve portion (V) of the percussion piston in a valve housing portion by periodically pressurising a signal chamber (21) actuating the movement of the valve element over signal conduit means (22, 23, 24) . Said signal conduit means includes at least two signal conduit portions (23, 24) , which are arranged for essentially simultaneous pressurising through co-operation between a corresponding number of valve control edges (25, 26) on the valve portion of the percussion piston and edges (34, 35) of control chambers in the machine housing. The invention also concerns a percussion device and a rock drilling machine.
    • 一种用于控制用于具有第一室(5)的凿岩机的冲击装置(1)的往复冲击活塞(3)的机械壳体(2)中的运动的阀装置(V,4'),所述第一室可以是 加压用于冲击活塞(3)的前进驱动和可被加压以用于冲击活塞(3)的反向驱动的第二室(8),其中所述阀装置包括来回可动阀元件(20) 其运动通过周期性地对通过信号管道装置(22)致动阀元件的运动的信号室(21)作为对冲击活塞的阀部分(V)的位置的响应进行控制, ,23,24)。 所述信号管道装置包括至少两个信号管道部分(23,24),其布置成基本上同时通过冲击活塞的阀部分上的相应数量的阀控制边缘(25,26)之间的协作加压,以及 机器壳体中的控制室的边缘(34,35)。 本发明还涉及一种打击乐器和一种凿岩机。
