    • PROBLEM TO BE SOLVED: To provide a fuel filter device capable of preventing excessive increase in pressure inside a housing. SOLUTION: A first check valve 70 provided to a fuel introduction passage 126 consisting of a passage in an introduction pipe 30 and a passage in an introduction passage part 121, is equipped with a relief valve element 91 functioning as a relief valve. When pressure in a downstream part 126b from the first check valve 70 is higher than that in an upstream part 126a from the first check valve 70 by a predetermined value or more, the relief valve element 91 lifts to open so that fuel in the downstream part 126b from the first check valve 70 is refluxed to the upstream part 126a from the first check valve 70.

    • PROBLEM TO BE SOLVED: To provide a fuel filter device which keeps an internal fuel passage in a normal condition even when a pipe member mounted in a housing is subjected to great impacts. SOLUTION: A protruded portion 45 is formed on a delivery pipe 40 as the pipe member mounted in a mounting hole 133 of a cap 12 of the housing and a recessed portion 135 into which the protruded portion 45 can be fitted is formed in a cylindrical part 132 of the cap 12 to restrict the turn of the delivery pipe 40 around the axis of the mounting hole relative to the housing. An engaging body 50 engaged with the cylindrical part 132 has an annular plate part 51 which restricts the movement of the delivery pipe 40 in the direction of the axis of the mounting hole but does not restrict the turn of the delivery pipe 40 around the axis of the mounting hole when the delivery pipe 40 is subjected to impacts to give sacrificial damages to the protruded portion 45.

    • PROBLEM TO BE SOLVED: To provide a filter element using a filter medium fine in texture for a filter body, and capable of preventing the filter body from clogging and being obstructed even if filtering a fluid that contains a great amount of particles with a small particle size, and a filter apparatus provided with the same.SOLUTION: A filter body 22 where a fuel passes in the thickness direction of a filter medium is composed of a first filter medium 221 provided for a part of a fuel passing area in an extension direction of the filter medium, and a second filter medium 222 provided for the remainder of the fuel passing area. The second filter medium 222 is formed to be finer in texture and have higher filtration performance than the first filter medium 221.
    • 要解决的问题:提供一种过滤元件,其使用过滤体质量过细的过滤介质,并且即使过滤含有大量具有小颗粒的颗粒的流体,也能够防止过滤器堵塞并被阻塞 尺寸和设置有过滤器的过滤装置。其中燃料在过滤介质的厚度方向上通过的过滤器主体22包括:第一过滤介质221,其设置在沿着延伸方向的燃料通过区域的一部分 的过滤介质,以及为剩余的燃料通过区域提供的第二过滤介质222。 第二过滤介质222形成为更细微的结构,并且具有比第一过滤介质221更高的过滤性能。
