摘要： An in-tank fuel filter includes a body comprising layers of spun bonded and melt blown filtration media and a fitting for mounting the filter to an in-tank fuel pump inlet. An outer layer of the body is preferably spun bonded material which exhibits good abrasion resistance. One or more inner layers of melt blown filtration media define smaller pore sizes and thus exhibit smaller particle filtration capability. The mounting fitting is made of a fuel compatible material and may either be a multiple part device or be in-situ molded on the filter body. A separator may be disposed in the interior of the filter to prevent its collapse and improve fuel withdrawal through the mounting fitting.

摘要： A compact, high capacity in-tank fuel filter defines a large surface area while simultaneously occupying a relatively small space and defining a small footprint. The filter comprises a body of filtration media and an outlet fitting which is integrally molded to the filtration media and provides communication from the interior of the filter to an associated fuel pump to which it is typically mounted. The filtration media of the body is folded upon itself in a multiple accordion fold configuration and sealed along the non-folded edges. The resulting surface area to size (footprint) ratio provides improved flow capacity, reduced pressure drop and extended service life.
摘要翻译：紧凑，高容量的油箱内燃油过滤器定义了大的表面积，同时占据相对较小的空间并限定了小的占地面积。过滤器包括过滤介质体和出口配件，该出口配件与过滤介质整体模制，并且提供从过滤器内部到其通常安装到的相关联的燃料泵的连通。身体的过滤介质以多种折叠折叠构型自身折叠，并沿非折叠边缘密封。所得到的表面积与尺寸（占地面积）比提供了改善的流动能力，降低的压降和延长的使用寿命。

摘要： An in-tank fuel filter includes a body having upper and lower panels comprising an outer shell or layer of extruded mesh, layers of spun bonded and melt blown filtration media and a fitting for mounting the filter to an in-tank fuel pump inlet. The outer layer of the body is extruded mesh material that has the general appearance of a woven fabric but includes connections at every filament intersection. This outer layer protects the finer, inner filtration layers which include a first layer of spun bonded material, a layer of melt blown filtration media defining smaller pore sizes and a second layer of spun bonded material. The mounting fitting is made of a fuel compatible material and may either be a multiple part device or be in-situ molded on one of the filter panels. Separating ribs or a stuffer may be disposed in the interior of the filter to prevent its collapse and improve fuel withdrawal through the mounting fitting.
摘要翻译：一种内燃机燃料过滤器包括具有上和下板的主体，该主体包括外壳或挤压网的层，纺粘和熔喷过滤介质层以及用于将过滤器安装在舱内燃料泵入口的配件。身体的外层是挤出网状材料，其具有机织织物的一般外观，但包括在每个细丝交点处的连接。该外层保护更细的内部过滤层，其包括第一层纺粘材料层，限定较小孔径的熔喷过滤介质层和第二层纺粘材料层。安装配件由燃料相容的材料制成，并且可以是多部件装置，也可以在其中一个过滤板上原位模制。分离的肋或填料可以设置在过滤器的内部，以防止其塌陷并改善通过安装配件的燃料抽出。
