    • A silencer for a two-stroke motor of a power tool, including a silencer inlet to which adjoins a flow channel of channel length so that the flow channel can be connected to an outlet of a combustion chamber of the two-stroke motor, whereby the flow channel at the channel end opposite the silencer inlet opens out into a first chamber of depth, between the silencer inlet and the first chamber the flow channel is so flow-beneficially designed, that due to its mass inertia the exhaust gas flowing into the silencer inlet predominantly flows into the first chamber and after filling the first chamber flows back again thereby creating a counterpressure in the direction of the combustion chamber, so that in spite of small geometric dimensions it provides a periodically actin counterpressure on the outlet of the combustion chamber of the two-stroke motor.
    • 一种用于电动工具的二冲程电动机的消音器,包括消音器入口,其邻接通道长度的流动通道,使得流动通道可连接到二冲程电动机的燃烧室的出口,由此, 在消音器入口相对的通道端处的流动通道开口进入第一深度室,在消音器入口和第一室之间,流动通道被有益地设计,由于其质量惯性,流入消音器的废气 入口主要流入第一室,并且在填充第一室之后再次流回,从而在燃烧室的方向上产生反压力,使得尽管具有小的几何尺寸,但它在燃烧室的出口处提供周期性的肌动蛋白反压力 二冲程电机。

    • A silencer for a two-stroke engine includes a first chamber and a second chamber, wherein a flow channel is provided between an outlet of a combustion chamber and the first chamber. A high charge degree of the combustion chamber has a pressure ratio in the region of the outlet which reduces or prevents an escape of fresh gas from the combustion chamber. The flow channel between the outlet and the first chamber is flow-favorably shaped in such a manner that the exhaust gas that flows out of the outlet because of its mass inertia predominantly flows into the first chamber and following charging of the first chamber flows back again and as a result a back pressure is formed in the direction of the combustion chamber.
    • 用于二冲程发动机的消音器包括第一室和第二室,其中在燃烧室的出口和第一室之间设置有流动通道。 燃烧室的高充电度具有在出口区域中的压力比,其减少或防止新鲜气体从燃烧室逸出。 出口和第一室之间的流动通道以这样一种流动方式成形,使得由于其质量惯性而流出出口的废气主要流入第一室并且在第一室的充电之后再次流回 结果,在燃烧室的方向上形成背压。
