    摘要： A suction air filter for a combustion engine includes a filter housing for receiving a filter insert and an attachment housing to which the filter housing is attached. The filter housing has a coupling end for coupling with a corresponding coupling end of the attachment housing. The suction air filter has an unfiltered air intake and a pure air outlet. A plurality of cam members are mounted on the outside of the filter housing near the coupling end thereof, and a plurality of cam elements are mounted on the outside of the attachment housing near the coupling end thereof. A rotatable coupling ring is mounted to receive the coupling ends of the filter housing and the attachment housing, and the coupling ring carries wedge members which are engagable with the cam members and the cam elements to releasably couple together the coupling ends of the housings. Dust protection shoulders or labyrinth seals are provided on both sides of the coupling ring to prevent dust from penetrating in the closure area of the attachment portion and the housing. A turning of the coupling ring effects a fixing of the filter housing to the attachment housing.

    摘要翻译： 用于内燃发动机的吸入空气过滤器包括用于接收过滤器插件的过滤器壳体和附接有过滤器壳体的附接壳体。 过滤器壳体具有用于与附接壳体的相应联接端联接的联接端。 吸入空气过滤器具有未过滤的进气口和纯净空气出口。 多个凸轮构件安装在过滤器外壳的靠近其连接端的外侧上，并且多个凸轮元件安装在附接壳体的外侧，靠近其联接端。 安装可旋转的联接环以接收过滤器壳体和附接壳体的联接端，并且联接环承载楔形构件，其可与凸轮构件和凸轮元件接合，以将壳体的联接端可释放地联接在一起。 在联接环的两侧设有防尘肩部或迷宫式密封，以防止灰尘渗入附件部分和外壳的封闭区域。 联接环的转动影响过滤器壳体与附接壳体的固定。

    摘要： An air intake filter for the internal combustion engine of a motor vehicle in which a substantially cylindrical housing contains an annular filter insert through which the air flows radially from the outside to the inside. At one end of the housing an end opening of the filter insert sealingly engages a tubular projection which communicates with the clean air outlet so that the filter insert is centered within the housing. At its opposite end, the filter insert is closed by a cover and is provided with fastening elements which engage in the junction between the housing and the cover, so that the fastening of the cover to the housing simultaneously serves to axially and radially secure the filter insert in place. Alternatively, the cylindrical housing may be formed of two, semicylindrical half-shells, and the filter insert may be provided with an annular bead which mates with a corresponding indentation in the housing to assure proper installation of the filter insert.

    摘要翻译： 一种用于机动车辆的内燃机的进气过滤器，其中基本上为圆柱形的壳体包含环形过滤器插入件，空气通过该环形过滤器插入件从外部向内部径向流动。 在壳体的一端，过滤器插入件的端部开口密封地接合与清洁空气出口连通的管状突出部，使得过滤器插入件在壳体内居中。 在其相对端，过滤器插件由盖封闭，并且设置有紧固元件，其紧固在壳体和盖之间的接合处，使得盖同时用于轴向和径向地固定过滤器 插入到位。 或者，圆柱形壳体可以由两个半圆柱形半壳形成，并且过滤器插入件可以设置有与壳体中的相应凹口配合的环形凸缘，以确保过滤器插入件的正确安装。
