A cartridge upper cover 32 and a cartridge lower cover 33 are fixed to both ends of the filter cartridge 31. The cartridge upper cover 32, the cartridge lower cover 33 and the filter element 31 are integrally located in the outer housing 10. An upper seal 34 is positioned between the cartridge upper cover 32 and the housing cover 20. The cartridge top cover 32 is formed with a hollow guide post that extends at least partially into the filter cartridge 31. The hollow guide pillar is communicated with the oil outlet.
As a preferred embodiment, a structurally stable filter 100 further comprises: water collection cup 40, inner support sleeve 50, spring leaf 60 and lower sealing ring 70.
The filter element 31 filters particulate impurities in the diesel fuel and simultaneously blocks water in the diesel fuel, and the water cannot flow to the engine through the filter element and only flows downwards into the water collecting cup 40.
The outer case 10 includes: an outer peripheral wall portion 11, a horizontal annular bottom plate portion 12, and a vertical wall portion 13 which are integrally formed. The outer housing 10 is integrally formed as one piece. The case cover 20 is mounted to the top end of the outer peripheral wall portion 11. The outer edge of the horizontal annular bottom plate portion 12 is connected to the bottom end of the outer peripheral wall portion 11. The inner edge of the horizontal annular bottom plate portion 12 is connected to the bottom end of the vertical wall portion 13. The inner support sleeve 50 is located between the outer peripheral wall portion 11 and the vertical wall portion 13.
The inner support sleeve 50 is formed with an internal thread structure 51. The water collecting cup 40 is formed with a male screw structure 41 screw-coupled with the female screw structure 51. The water collecting cup 40 is screwed to the inner support sleeve 50 by the threaded connection of the internal thread structure 51 and the external thread structure 41. The inner support sleeve 50 is also formed with a through-hole 52 for communicating the inside of the outer case 10 and the inside of the water collecting cup 40. The water accumulated in the outer case 10 may enter the water collecting cup 40 through the penetration hole 52, and may be discharged through the water discharge valve 43.
