摘要： A working tool in which a tip tool with a longitudinal shaft is linearly moved, wherein a motor and other tool constituting members are effectively cooled. In order to cool the inside of a motor-driven hammer comprising a main body, a motor, and a motion converter, the hammer is provided with a first cooling air passage through which a cooling air is supplied to the motor, and a second cooling air passage through which a cooling air is supplied to a hammer portion. To generate a cooling air to be supplied to the first and second cooling air passages, a cooling fan is provided at a lower portion of an output shaft of the motor and a hammer portion cooling fan is provided between the output shaft of the motor and the motion converter.

摘要： A dust collection device, that collects dust particles generated by an impact tool, has a feature that enables the attachment of the device to the impact tool, which is not provided with an attachment section for the device. The dust collection device has a tool body and an auxiliary handle, attached removably to the tool body, and is attached to an electric hammer that, in the lengthwise direction, linearly operates a tool bit mounted to the tip region of the tool body, and collects dust generated by the electric hammer. The dust collection device has: a dust collection unit that has a dust intake port at the tip; a dust collection hose, connected to the dust collection unit, for transferring dust to the downstream side; and a hose-holding unit that holds the dust collection hose. The hose-holding unit can be attached to and removed from the auxiliary handle.

摘要： A percussion tool has a cooling air channel for guiding a cooling air flow from a cooling air fan to an outside wall of a cylinder of an internal combustion engine. The cooling air channel is tapered to the extent that partial cooling air flows guided between the respective cooling fins are branched off the main cooling air flow. In such a way, the flow rate of the cooling air flow in the cooling air channel remains substantially constant, resulting in optimized engine cooling. The cooling air channel may be divided into two cooling air channels downstream of the cylinder. One of the cooling air channels guides cooling air to an exhaust gas system of the internal combustion engine, while the other cooling air channel guides cooling air to an outside wall of the guide housing of a hammer mechanism.
摘要翻译：冲击工具具有冷却空气通道，用于将来自冷却风扇的冷却空气流引导到内燃机的气缸的外壁。冷却空气通道是锥形的，使得在相应冷却翅片之间引导的部分冷却空气流从主冷却空气流分支。以这种方式，冷却空气通道中的冷却空气流的流速保持基本恒定，从而优化发动机冷却。冷却空气通道可以在气缸下游分成两个冷却空气通道。冷却空气通道中的一个将冷却空气引导到内燃机的排气系统，而另一个冷却空气通道将冷却空气引导到锤机构的引导壳体的外壁。
