    Abstract: A cartridge group is for a filter assembly of a fuel filtration system. The cartridge group extends along an axis and includes a filter septum crossable in an axial direction by the fuel. The filter septum has an annular shape and defines at the axis a central cavity. A water separation and support device supporting the filter septum includes: i) a base element supporting the filter septum and presenting channels and/or holes through which the filtered fuel flows; ii) a tubular element extending into the central cavity presenting an outlet duct having a substantially annular cross-section delimited by an outer circumferential wall and an inner circumferential wall delimiting along the axis a through central passage; iii) a separator element crossable by the filtered fuel to be separated from the water. The separator element is housed on the base element and/or on the inner circumferential wall of the tubular element.

    Abstract: The present invention relates to water feeder technical field, more particularly to a filter assembly and a portable water feeder. The filter assembly includes a tray and a filter piece; the tray comprises a bottom frame with a bottom plate and a supporting wall and a supporting ring, the supporting wall is arranged around its circumference of the bottom plate and extends upward, the supporting wall and the bottom plate are jointly surrounded to form a cavity, and the bottom plate is provided with a number of filter holes; the supporting ring is arranged above the bottom frame and is connected to its top of the supporting wall, the filter piece is placed in the cavity. When the filter assembly is used, water flows from the filter hole into the filter piece, and the filter assembly has the advantages of simple and compact structure.

    Abstract: This description presents liquid filter comprising filter housing containing all parts of the filter; filtering element trapping impurities present in liquid being filtered; solid support element preventing filtering element from getting deformed, filter housing cover, and other components.The most important element presented in this description is filter support stem enabling the use of filter with extreme pressure levels of the filtered liquid (up to 300 MPa) and sudden changes to these levels. The support stem prevents filtering element from getting deformed to the extent that would render it unfunctional.One of the possible applications of the filter presented herein is filtering high-pressure diesel fuel between high-pressure pump and injectors.An important feature of this liquid filter is that it is not integrated into other standard parts of fuel system, but added to fuel system as separate component that can be easily replaced without replacing other parts of the system.To improve durability and ensure reusability of filtering element of liquid filter this element is made of metal or other material possessing similar properties.
