Zusammenfassung: | PROBLEM TO BE SOLVED: To provide a structure of an air filter which does not have influences on the measurement accuracy of an air flow rate measuring device.SOLUTION: In an air filter assembly having a primary filter element 200, a secondary filter element 250, and a housing with an outlet pipe 150, the primary filter element is operably inserted in the housing 102 and regulates an inner capacity. The secondary filter element is operably inserted in the inner capacity of the primary filter element. An opening end portion cap 256 of the secondary filter element regulates a sealing structure having a first part extending into the inner capacity of the second filter. The outlet pipe is operably connected to an air outlet opening portion 116 of the housing, and includes an insertion ring. At least a part of the insertion ring is arranged in the inner capacity of the secondary filter, and the insertion ring is extended over at least a part of the first part of the sealing structure.SELECTED DRAWING: Figure 3
【課題】空気流量測定装置の測定精度に影響を及ぼさないエアフィルタの構造を提供する。【解決手段】一次フィルタエレメント200と二次フィルタエレメント250と出口管150を備えるハウジングとを有するエアフィルタアセンブリにおいて、一次フィルタエレメントはハウジング102の中に動作可能に挿入され且つ内部容積を規定する。二次フィルタエレメントは一次フィルタエレメントの内部容積の中に動作可能に挿入される。二次フィルタエレメントの開放された端部キャップ256は二次フィルタの内部容積の中へ延出する第1の部分を有する密封構造を規定する。出口管はハウジングの空気出口開口部116に動作可能に接続され且つ差込み環を含み、差込み環の少なくとも一部は二次フィルタの内部容積の中に配設され、且つ差込み環は密封構造の第1の部分の少なくとも一部に渡って延設される。【選択図】図3 |
