Abstract: This filter element (1) comprises a filter medium (3) configured with an annular shape, having a central axis (X1) and forming inside a central channel (4) extending substantially axially, a first and a second end plates (5, 6), each plate covering one axial end of the filter medium (3) and being sealingly mounted on said axial end, the first end plate (5) having a central opening (7) substantially coaxial with the central axis (X1) and in fluid communication with the channel (4), and a central perforated rigid tube (9) that extends axially between the first and second end plates (5, 6) and having an inner perforated wall delimiting the central channel (4). The filter element (1) is designed to be placed in a filter housing (14) for forming a liquid filtering device (10), whereby a liquid to be filtered can flow along a liquid path through the filter medium (3) towards the channel (4) and out of the filter element (1) through the central opening (7). The central perforated rigid tube (9) comprises at least one guiding path (24), arranged inside the central perforated rigid tube (9), adapted to generate, by contact with a following member (204) of a rotatable central element (200) of the filter housing (14), at least a first, progressive rotational movement (A5) of the rotatable element (200) of the filter housing (14) when the filter element (1) is mounted in the filter housing (14) during a first translation movement (A1) along the central axis (X1). The at least one guiding path (24) comprises at least one portion of helical path (24A) for obtaining the first, progressive rotational movement (A5), and the helical path (24A) extends on less than half of the inner periphery of the central perforated rigid tube (9) in order to generate a rotation of the rotatable element (200) inferior to one half of a turn.

Abstract: A filter element is provided and includes a filter medium having an axial channel, end plates each sealingly covering one axial end of the filter medium, one end plate having an opening in fluid communication with the channel, a hole arranged on the liquid path, not on the filter medium, and a closing member which is arranged in the hole and which is configured: to prevent liquid from flowing through the hole when the liquid pressure upstream the closing member is below a predetermined threshold to open at the threshold, to allow liquid to flow through the hole, and, after it has been opened, to remain open. A method is provided for checking the suitability of a filter element, at first use after a filter element change. The method includes monitoring the liquid pressure at a point of the liquid circuit located outside of and near a port of a filter housing receiving the filter element, when an electrical pump of the liquid circuit is restarted for the first time, comparing the evolution of the monitored liquid pressure over time with a predetermined evolution over time of the liquid pressure at the point for a new reference filter element.

Abstract: A filter element includes:a filter medium having an axis and forming an axial channel; a first and a second end plates, each end plate covering one axial end of the filter medium and being sealingly mounted on the axial end, the first end plate having an central opening coaxial and in fluid communication with the channel; the filter element being 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 filter element further includes further includes a detachable plug whose position can change from an attached position to a detached position. In the attached position the detachable plug is attached to an immobile portion of the filter element and seals the central opening, and in the detached position the detachable plug is detached from the immobile portion and is movable away from the central opening inside the channel and along the filter element axis to unseal the central opening.

Abstract: In a fuel system for delivering pressurized fuel both to an internal combustion engine and to an exhaust installation, the fuel system includes two separate branches for delivering fuel to the internal combustion engine and to the exhaust installation, and includes a primary fuel pump delivering fuel to both branches of the fuel supply circuit. The primary fuel pump output is controllable independently of the engine speed. The pump output may be controlled such that the pressure of fuel in the fuel supply circuit depends on whether fuel is to be delivered to the exhaust installation. The fuel system may include a hydraulically controlled shut-off valve arrangement which is forced to switch depending on the pressure in the fuel supply circuit.
