Description
この場合、本発明の請求項3に記載のフィルタのように、予備濾過体を流体の流れ方向に沿って積層配置された複数の濾材層から構成するとともに、本発明の請求項4に記載のフィルタのように、複数の濾材層の目の粗さは、濾過体と隣接する濾材層の目の粗さが最も細かく、流体の流れ方向上流側に位置する濾材層ほど順次粗くなるように設定される構成とすれば、フィルタ全体としての密度勾配特性をより広範囲に拡大させることができる。
本発明の第1実施形態による燃料フィルタ10は、大きくは図1に示すように、所定位置に流体である燃料の導入口31aおよび排出口32aを設けたケーシング30と、このケーシング30内に収容される濾過体であるフィルタエレメント20とから構成されている。
図5に示すように、本発明の第2実施形態による燃料フィルタ10は、本発明の第1実施形態による燃料フィルタ10に対して、フィルタエレメント20の上流側に予備濾過体であるプライマリフィルタ50を積層配置している点のみが異なっている。

Claims (5)
- 流体の導入口および排出口を備えるケーシングと、
前記ケーシング内において前記導入口と排出口との間に収容される濾過体と、を備え、
流体を前記導入口から前記ケーシング内へ導入し前記濾過体を通過させて前記排出口から前記ケーシング外へ排出するフィルタであって、
前記濾過体の流体の流れ方向に沿う面である外周面の全部あるいは一部が流体の流れ方向に変形を規制するように拘束され、
前記濾過体における流体の流れ方向下流側の端面である下流側端面から前記濾過体における流体の流れ方向上流側の端面である上流側端面に向かって前記濾過体を押圧圧縮したフィルタにおいて、
前記ケーシングは前記濾過体の前記下流側端面に当接して前記上流側端面に向かって前記濾過体を圧縮する圧縮部材を備え、
前記圧縮部材の前記濾過体に当接する当接面は前記濾過体の前記上流側端面に向かって突出する曲面状に形成されることを特徴とするフィルタ。 - 前記濾過体の上流側に目の粗さが前記濾過体よりも粗い予備濾過体を積層配置したことを特徴とする請求項1に記載のフィルタ。
- 前記予備濾過体は流体の流れ方向に沿って積層配置された複数の濾材層から構成されることを特徴とする請求項2に記載のフィルタ。
- 複数の前記濾材層の目の粗さは、前記濾過体と隣接する濾材層の目の粗さが最も細かく、流体の流れ方向上流側に位置する前記濾材層ほど順次粗くなるように設定されることを特徴とする請求項3に記載のフィルタ。
- 前記濾過体、前記予備濾過体および前記濾材層は不織布、繊維集合体または連泡構造を有する樹脂から形成されることを特徴とする請求項3又は4に記載のフィルタ。
