摘要： A filter device, especially an intake air filter for internal combustion engines, comprises a cylindrical filter housing (1) with inlet and outlet openings (7, 6) for the medium. In the outlet opening, the pipe stub (11) is fixed with the aid of an elastic sleeve (12). The pipe stub is solidly joined to a secondary or safety filter (20) which extends within a main filter (2), which has a radial seal (17) which seals against a portion (11a) of the pipe stub extending into the housing.

摘要： Arrangement for purification of hot exhaust gases from internal combustion engines and comprising a housing provided with a gas inlet (6) and a gas outlet (7) for the flow of gases through the inside of the housing, and a gas purification unit arranged in the housing between the gas inlet and the gas outlet. Between the peripheral casing wall (20) of the purification unit (16) and the wall of the housing there is a closed, gas-tight element (23) which extends peripherally round the purification unit and through the heat-insulating layer and is designed as a three-dimensional shell with an inner attachment (26) on the casing wall of the purification unit and an outer attachment (25) on the wall (8, 9) of the housing. The inner attachment is situated at a level which is nearer the outlet side of the purification unit than the level of the outer attachment. In this way the gas-tight element with its inner and outer attachments forms a gas-tight securing arrangement for the purification unit in the housing with minimal heat losses.
摘要翻译：用于净化来自内燃机的热废气的装置，包括设置有气体入口（6）的壳体和用于气体通过壳体内部的气体出口（7），以及气体净化单元气体入口和气体出口之间的外壳。在净化单元（16）的周边壳体壁（20）和壳体壁之间存在封闭的气密元件（23），其围绕净化单元延伸并穿过隔热层并被设计作为在净化单元的壳体壁上具有内部附件（26）的三维壳体和在壳体的壁（8,9）上的外部附件（25）。内部附件位于比外部附件的水平更靠近净化单元的出口侧的水平面上。以这种方式，具有其内部和外部附件的气密元件形成用于壳体中的净化单元的气密固定装置，具有最小的热损失。

摘要： A filter device, especially an intake air filter for internal combustion engines, comprises a cylindrical filter housing (1) with inlet and outlet openings (7, 6) for the medium. In the outlet opening (6), a pipe stub (11) is fixed with the aid of an elastic sleeve (12), which forms a seal between the opening edge (14) and the stub and between the stub and an intake conduit (15) coupled thereto. The pipe stub has a portion (11a) extending into the filter housing, against which portion (11a) there seals a radial seal (17) on a filter element (2) enclosed in the housing.
