    • A pneumatic percussion tool (1) for demolition and/or breaking work is connectable to an insert tool (2). The percussion tool has a percussion cylinder (4), a piston (5), arranged to travel in the bore of the cylinder (4), a buffer (8), and a valve unit (6), acting on the piston (5) during operation to produce a repetitive reciprocating motion in the bore of the cylinder (4) by alternately applying pressure to the upper or lower end of the cylinder (4) while the insert tool (2) is influenced by the stroke of the piston (5) at its dead center at the lower end of the cylinder (4). The percussion tool prevents the reciprocating motion of the piston when the buffer (8) reaches a predetermined degree of wear and the tool is not pressed against any object being worked.
    • 用于拆卸和/或断开工作的气动冲击工具(1)可连接到插入工具(2)。 冲击工具具有冲击缸(4),活塞(5),其布置成在气缸(4)的孔中行进,缓冲器(8)和作用在活塞(5)上的阀单元(6) ),通过在插入式工具(2)受到活塞行程的影响的同时向气缸(4)的上端或下端交替施加压力,以在气缸(4)的孔中产生重复的往复运动 5)在其在缸(4)的下端的死点处。 当缓冲器(8)达到预定磨损程度并且工具没有被压在任何被加工物体上时,冲击工具可防止活塞的往复运动。

    • A pneumatic percussion tool (1) for demolition and/or breaking work in for example concrete and connectable to an insert tool (2). The percussion tool has a percussion cylinder (4), a piston (5), arranged to travel in the bore of the cylinder (4), a buffer (8), and a valve unit (6), designed to act on the piston (5) during operation and produce a repetitive reciprocating travel in the bore of the cylinder (4) by alternately applying pressure to the upper or lower end of the cylinder (4) while the insert tool (2) is subject to influence by the stroke of the piston (5) when this is at its dead centre at the lower end of the cylinder (4). The percussion tool comprises a means (11) of preventing the piston's reciprocating motion when the buffer (8) reaches a predetermined degree of wear and the tool is not pressed against any object being worked.
    • 一种气动打击工具(1),用于在例如混凝土中拆卸和/或断裂工作,并可与插入工具(2)连接。 冲击工具具有冲击气缸(4),活塞(5),布置成在气缸(4)的孔中行进,缓冲器(8)和阀单元(6),设计成作用在活塞 (5),并且在插入工具(2)受到行程的影响的同时,通过在气缸(4)的上端或下端交替地施加压力,在气缸(4)的孔中产生重复的往复运动 当其位于气缸(4)的下端处于其死点时。 冲击工具包括当缓冲器(8)达到预定磨损程度时防止活塞往复运动的装置(11),并且该工具没有压靠任何被加工物体。

    • Disclosed is a drilling and/or striking hammer that includes a lubricating device having a lubricant reservoir and a volume of lubricant contained therein. The lubricating device conveys lubricant to at least one a transmission system within the hammer's housing, a percussion system, and/or a tool holder at a variable dosing or flow rate. The dosing or flow rate varies as a function of tool stress which can include use intensity and/or temperature. A flexible tube extends between the reservoir and the lubricated component(s). At lease part of the flexible tube vibrates with the lubricated components during use and modifies a viscosity of the lubricant therein, based on tool use intensity. A pressure generating device can pressurize the lubricant, helping convey the lubricant to a targeted area for lubricating movable parts.
    • 公开了一种钻孔和/或打击锤,其包括具有润滑剂储存器和其中容纳的润滑剂的体积的润滑装置。 润滑装置将润滑剂输送到锤子壳体内的至少一个传动系统,冲击系统和/或可变计量或流量的工具保持器。 剂量或流量随刀具应力的函数而变化,其可以包括使用强度和/或温度。 柔性管在储存器和润滑部件之间延伸。 柔性管的至少一部分在使用期间与润滑的部件振动,并且基于工具使用强度改变其中的润滑剂的粘度。 压力发生装置可以对润滑剂加压,有助于将润滑剂输送到目标区域以润滑可动部件。
