    • An apparatus for transmitting sound in a motor vehicle having a housing (1) with an inner partition (2), which together define two separate subspaces (3, 4). A transmission valve (6) which separates the two subspaces (3, 4) is provided in a pivot bearing opening (9) in the partition (2) and is mounted to pivot about a pivot axis (5) in the area of the pivot bearing opening (9). The first subspace (3) is connected in a manner capable of transmitting sound to an intake manifold (17) of an internal combustion engine, and the second subspace (4) is connected in a manner capable of transmitting sound to an interior space of the motor vehicle. The gap (11) between an edge (10) of the pivot bearing opening (9) and the transmission valve (6) is sealed in a pressure-tight manner by a membrane (12).
    • 一种用于在机动车辆中发射声音的装置,其具有带有内部分隔件(2)的壳体(1),它们共同限定两个单独的子空间(3,4)。 分离两个子空间(3,4)的传动阀(6)设置在分隔件(2)中的枢转轴承开口(9)中,并且安装成绕枢轴的枢转轴线(5)枢转 轴承开口(9)。 第一子空间(3)以能够将声音发送到内燃机的进气歧管(17)的方式连接,并且第二子空间(4)以能够将声音传输到内燃机的内部空间的方式连接 摩托车。 枢转轴承开口(9)的边缘(10)与传动阀(6)之间的间隙(11)通过膜(12)以压力密封的方式被密封。

    • A muffler construction, particularly for exhaust gases of air-operated tools, comprises, a tubular sleeve having a passage therethrough, an exhaust gas pipe connected into the sleeve and defining a restricted flow passage with the sleeve, first and second opposed cylindrical coaxial shell sections, each having a closed end wall at their respective outer ends and facing in opposite directions engaged with the exhaust gas pipe, and sidewalls spaced radially outwardly from the sleeve. The exhaust gas pipe has a gas pipe discharge and there are partition walls in the shell sections defining a first expansion chamber and at least one additional expansion chamber. A constricted flow passage is defined between the first expansion chamber and the at least one additional expansion chamber with sealing and enclosing members closing the sidewalls of the first and second shell sections so as to define the first expansion chamber and at least one additional expansion chamber within the shell sections. The exhaust gases from the discharge enter into the first expansion chamber and form a vortex therein with the gases then flowing into the restricted passage into the additional chamber wherein a second vortex is generated. A final gas discharge is defined in the wall of the second shell sections which communicates with the atmosphere.
    • 特别是用于气动工具的废气的消音器结构包括:具有通过其的通道的管状套筒,连接到套筒中并且限定具有套筒的限制流动通道的排气管,第一和第二相对的圆柱形同轴壳体部分 ,每个在它们各自的外端处具有封闭的端壁并面向与排气管接合的相反方向,以及与套筒径向向外隔开的侧壁。 排气管具有气体管排放,并且在壳部中存在限定第一膨胀室和至少一个附加膨胀室的隔壁。 在第一膨胀室和至少一个附加膨胀室之间限定收缩流动通道,其中密封和封闭构件封闭第一和第二壳体部分的侧壁,以便限定第一膨胀室和至少一个附加膨胀室 外壳部分。 来自排放物的废气进入第一膨胀室并在其中形成涡流,然后气体流入限制通道进入附加室,其中产生第二涡流。 在与大气连通的第二壳部分的壁中限定最终气体排放。
