Abstract

This filter element () comprises a filter medium () configured with an annular shape, having a central axis (X) and forming inside a central channel () extending substantially axially, a first and a second end plates (), each plate covering one axial end of the filter medium () and being sealingly mounted on said axial end, the first end plate () having a central opening () substantially coaxial with the central axis (X) and in fluid communication with the channel (), and a central perforated rigid tube () that extends axially between the first and second end plates () and having an inner perforated wall delimiting the central channel (). The filter element () is designed to be placed in a filter housing () for forming a liquid filtering device (), whereby a liquid to be filtered can flow along a liquid path through the filter medium () towards the channel () and out of the filter element () through the central opening (). The central perforated rigid tube () comprises at least one guiding path (), arranged inside the central perforated rigid tube (), adapted to generate, by contact with a following member () of a rotatable central element () of the filter housing (), at least a first, progressive rotational movement (A) of the rotatable element () of the filter housing () when the filter element () is mounted in the filter housing () during a first translation movement (A) along the central axis (X). The at least one guiding path () comprises at least one portion of helical path (A) for obtaining the first, progressive rotational movement (A), and the helical path (A) extends on less than half of the inner periphery of the central perforated rigid tube () in order to generate a rotation of the rotatable element () inferior to one half of a turn.
