Embodiment Construction

[0076] Vehicles are usually equipped with a liquid filter device 1 eg for filtering oil or fuel.

[0077] Such as Figure 29 to Figure 34 As shown in , such a liquid filter device 1 includes a housing 2 including a housing 3 and a cover 7 . The substantially cylindrical housing 3 has an axis 10 and comprises a bottom wall 4 , a peripheral wall 5 , and an open axial end 6 opposite the bottom wall 4 . A cover 7 is detachably secured to the housing 3 at its open axial end 6 . For example, the cover 7 comprises a disc-shaped plate 8 and a skirt 9 provided with an external thread for cooperating with the internal thread of the peripheral wall 5 of the housing 3 . Two ports 11, 12 are arranged in the housing 2, one port being the inlet for the liquid to be filtered and the other port being the outlet for the filtered liquid. A conduit is mounted sealingly in fluid communication with each of said ports 11 , 12 for conveying liquid to be filtered / filtered liquid.

Abstract

A filter element (20) comprises: a filter medium (21) having an axis and forming a channel (22) extending substantially axially; a first and a second end plates (25, 26), each end plate covering one axial end of the filter medium and being sealingly mounted on said axial end, the first end plate (25) having an opening (27) in fluid communication with the channel (22); whereby a liquid to be filtered can flow through the filter medium (21) towards the channel (22) and out of the filter element (20) through the opening (27), or reversely. The filter element further comprises: a protrusion fixedly secured to the first end plate (25) and extending outwardly from said first end plate, the protrusion being substantially tubular and having a through hole in fluid communication with the first endplate opening, the protrusion forming a female coupling piece (100) of a male-female connector (50); a locking member (300) capable of releasably locking a male coupling piece (200) of said male-female connector (50) in the female coupling piece (100).

Description

technical field [0001] The invention relates to a filter element, in particular a filter element for filtering liquids, such as fuel or oil, in vehicles. The invention also relates to a liquid filter device comprising such a filter element, and a vehicle comprising such a liquid filter device. [0002] The invention can be applied to heavy vehicles such as trucks, buses and construction equipment. Background technique [0003] Liquid filters are often provided in vehicles to remove contaminants from said liquid which may be, for example, fuel or oil. [0004] Conventional filter elements may include filter media forming axial channels, the axial ends of which are covered by end plates sealingly mounted on the axial ends. Additionally, one end plate includes an opening in fluid communication with the channel. Such a filter element is housed in a housing comprising a housing and a cover, the housing comprising an inlet port for liquid and an outlet port, one of said ports b...
