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).

Abstract: This flow regulation device comprises a housing (200) having an inlet port (202) and an outlet port (204), and a fluid flow conduit (206) between them, a valve body (208) mounted in the housing (200), and a first (210) and a second (212) orifices allowing fluid flow in the conduit (206). The valve body (208) is movable between an open position, in which the first and second orifices (210, 212) are open, and a closed position, in which only one (210) of the first and second orifices (210, 212) is open. The flow regulation device (20) comprises a resilient element (214) urging the valve body (208) towards its open position, and the valve body (208) passes from its open to its closed position under action of fluid pressure (P) entering in the inlet port (202).

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.

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.
