をはかっている。2. Description of the Related Art Heretofore, a filter element accommodated in an oil filter or the like has been one in which an inner tube formed of a perforated metal plate or the like maintains strength and a filter material folded around it in a chrysanthemum shape is arranged. The filter medium is often a double layer, and the outside has a filter aperture larger than that of the inside, and the coarse dust is trapped in the previous stage to extend the life.

通過する濾液に対し圧力損失をできるだけ少くする必要
があるが、従来の圧力損失の発生状態をみると、インナ
チューブが最も大きい抵抗体となり、圧力損失の最も大
きい要因となっていることが知られる。It is necessary for the filter element to minimize the pressure loss with respect to the filtrate passing therethrough. However, in view of the conventional pressure loss occurrence state, the inner tube is the largest resistor, and the pressure loss is large. It is known that this is the largest factor.

メントはインナチューブを廃止し、濾材を3重に重ね、
最外層と最内層とを中間層に比し濾口径が大でやや剛性
のあるものにしたフィルタエレメントである。The filter element of the present invention eliminates the inner tube, and the filter media are stacked in three layers.
This is a filter element in which the outermost layer and the innermost layer have a filter diameter larger than that of the intermediate layer and are slightly rigid.

ブのような抵抗体とならず、圧力損失は少なくなる。[Function] The filter media of the outermost layer and the innermost layer have a large filter diameter,
For example, wire mesh has a large wire diameter, and fibrous material has a large rigidity due to the fact that the fiber is thick and the thickness is large.Therefore, when this is pleated and used as the innermost layer, the filter itself Can have strength equivalent to that of a conventional inner tube. Moreover, since it is a filter medium, it does not function as a resistor like an inner tube, and pressure loss is reduced.

径が太く若干の剛性を有している。1 and 2 show an embodiment. The filter element 1 is formed by adhering a non-perforated upper end plate 3 and a lower end plate 4 having a central opening to an end surface of a cylindrical filter body 2 folded in a chrysanthemum shape. The filter body 2 is formed by stacking an outermost layer filter medium 5, an intermediate layer filter medium 6, and an innermost layer filter medium 7. The filter materials 5 and 7 are 100 mesh wire nets made of stainless steel, and the filter material 6 is a 300 mesh wire mesh made of stainless steel. These filter materials may be brass wire mesh, or synthetic resin mesh such as nylon. In both cases, the filter media 5 and 7 have a larger wire diameter than the filter media 6 and have some rigidity.

筒状に締め付けられて瀘過体2を形成する。It is also possible to use thick filter paper having thick fibers and a large filter diameter as the filter material of the outermost layer and the innermost layer, and use thin filter paper having fine fibers and a small filter diameter for the intermediate layer. These filter media are 3
The layers are overlapped with each other and folded, and are crimped in a tubular shape by caulking metal fittings (struts) 8 to form a filter body 2.

にすれば瀘過体作成工程が容易になる。As shown in FIG. 3, the outermost filter medium 9 and the innermost filter medium 11 may be constituted by one continuous filter medium, and the intermediate filter medium 10 may be sandwiched and folded. In this way, the filter body manufacturing process becomes easy.

る。As shown in FIG. 4, the innermost filter medium 14 may have a double structure composed of filter mediums 14a and 14b. In this case, the filter media 14a and 14b are of the same quality as the outermost filter media 12,
It has a larger filter diameter and slightly higher rigidity than the filter material 13 of the intermediate layer.

止し、目づまり寿命の長期化がはかられる。In the filter element of the present invention, the inner tube is abolished and replaced by a filter material having a slightly rigid innermost layer and a large filter aperture, thereby reducing the pressure loss while maintaining the required strength. It is a filter element. Moreover, since the innermost layer of the filter material is reinforced from the inside of the folds, the tendency of the folds to be crushed by the hydraulic pressure from the outside can be prevented, and the clogging life can be extended.
