Abstract: The present application relates to the field of fuel filter components of internal combustion engines, and discloses a fuel filter element, including a filter element main body and a protective cover. A fuel return column extends from an upper end surface of the filter element main body. The protective cover is formed with a U-shaped groove adapted to the fuel return column, is adaptively installed on the filter element main body and is of an annular hollow structure. The U-shaped groove accommodates the fuel return column to form a protective assembly. Therefore, the problem of poor sealing caused by installation deformation damage and installation deviation of the fuel return column, and the cost of a hollow structure of the protective cover are reduced.

Abstract: The present application discloses a fuel-water separation filter element capable of exhausting gas, and a filter. The filter element includes a filter element frame, a filter medium, and an exhaust valve assembly. An upper end cover and a lower end cover are arranged at an upper end and a lower end of the filter element frame. The upper end cover is provided with a recess surface along an axial direction of the filter element frame. The exhaust valve assembly includes a valve seat and a valve element. The valve seat and the recess surface form an exhaust cavity communicating with the inside of the filter element. The exhaust valve assembly in the present application can effectively exhaust gas in the filter.

Abstract: Disclosed are a filter element for liquid filtration and a filter. The filter element includes a ring filter medium, first and second end caps connected to the ring filter medium, and a ventilation assembly, where the ring filter medium has a central cavity formed around a central axis thereof; the ventilation assembly is disposed in the central cavity; and an intercepting ring groove is formed at a ring seal. In this technical solution, a sealing O-ring at a sealing part of the filter element and the housing assembly is replaced with the ring seal with a self-sealing function, which has a better sealing effect under an oil pressure and can reduce a compression amount; and while oil dirt is intercepted, the disassembly of the filter element is not affected, and especially under effective exhaust of the ventilation assembly, the disassembly is more labor-saving.

Abstract: The present application discloses a filter device, including a housing, a primary filter body, and a secondary filter body. The housing is formed with a first channel for fuel to flow in. The primary filter body includes a support fence, a particulate filter medium, and end covers. The secondary filter body is formed with a second channel for the fuel to flow out from the secondary filter body and is configured to block water and allow the fuel to pass. The filter device in the present invention can make it possible to arrange more particulate filter media in a limited space, thereby improving the filtration capacity of a filter element per unit volume.
