Rotatable sealed filter outlet
摘要：
An improved outlet tube (60) is provided for an air filter (10) of the type including a housing (12) having distally opposite axial ends (14 and 16), and a cylindrical filter element (34) in the housing (12), the cylindrical filter element (34) having an annular sidewall (40) with a hollow interior (58) and extending between distally opposite axial ends (48 and 50), wherein air flows radially inwardly through the annular sidewall (40) into the hollow interior (58) and then axially through the hollow interior (58). The outlet tube (60) is mounted to the axial end (14) of the housing (12) in snap-in relation and is rotatable relative thereto about the axis (62) of the cylindrical filter element (34) and communicates with the hollow interior (58) of the cylindrical filter element (34) for exhausting clean filtered air therefrom (64, 66). A seal (70) provides both axial and radial sealing of the outlet tube (60) to the housing (12), and seals the housing/outlet tube joint and allows the filter element (34) to seal both radially and axially with the housing/outlet tube assembly.
摘要（中）：

提供了一种用于空气过滤器（10）的改进的出口管（60），该空气过滤器（10）包括具有远端相对的轴向端（14和16）的壳体（12）和壳体（12）中的圆柱形过滤元件（34） 圆柱形过滤器元件（34）具有带有中空内部（58）并在远端相对的轴向端（48和50）之间延伸的环形侧壁（40），其中空气径向向内流过环形侧壁（40）进入中空 内部（58），然后轴向地穿过中空内部（58）。 出口管（60）以卡扣关系安装到壳体（12）的轴向端部（14），并且可相对于其围绕圆柱形过滤器元件（34）的轴线（62）旋转，并与中空部件 用于从其中排出清洁过滤的空气（64,66）的圆筒形过滤元件（34）的内部（58）。 密封件（70）提供出口管（60）到壳体（12）的轴向和径向密封，并且密封壳体/出口管接头并且允许过滤元件（34）径向和轴向地与壳体 /出口管总成。
