An electronic system providing unique identification of a genuine filter system assembly to the engine control unit (ECU). A resistor is made to be an integrated part of the filtration system hardware such that when connected through a wired connection, the ECU detects a particular voltage signal and identifies the system as a genuine filter. The resistor could be integrated in any part of the filter system such that it could be used to recognize the filter or the cartridge. The resistor connection could be made via male/female pins, conducting wires, plates, conductive plastic material or other mechanisms.

A purification device comprises a main body having an opening in a front-face thereof; a rotator disposed in the opening to be rotatably mounted on the main body; a manipulation structure spaced from and above the rotator and rotatably connected to a top face of the main body, the manipulation structure protruding forward of the main body; and a water-outlet including; a first cover fixed to the rotator through the opening, the first cover protruding forward of the main body, and a top of the first cover being connected to a bottom of the manipulation structure; a second cover vertically movable while being held in contact with the first cover; and a nozzle on a bottom of the second cover; wherein when the second cover rises to a highest level, a top of the second cover is located in a space between the rotator and the manipulation structure.

A heated filter shell assembly for a fuel filtration system includes a filter shell defining a cavity sized to accommodate at least a portion of a fluid filtration cartridge and a cartridge receiving aperture at a first end. A heating element is disposed within the cavity and is operatively coupled to the filter shell adjacent to a second end of the filter shell. A feed wire is operatively coupled to the heating element at a feed wire first end and is configured for electrical energy receiving communication with an energy source at a feed wire second end.

A filter element is provided with a filter medium and a first end disk connected to the filter medium. A first bayonet protrusion is disposed on the first end disk and designed to engage behind a first bayonet receptacle of a filter housing of a filter. The first bayonet protrusion has a free end. The first bayonet protrusion projects at least over sections thereof in a radial direction relative to a filter element longitudinal axis of the filter element past the filter medium. The free end projects in the radial direction toward the filter element longitudinal axis. A filter with a filter housing provided with a first bayonet receptacle is provided and the filter element is arranged in the filter housing such that the first bayonet protrusion on the first end disk engages behind the first bayonet receptacle of the filter housing.

A lubricant filter housing comprises a top plate defining a first opening. A base plate is positioned opposite the top plate. The lubricant filter housing further comprises at least one sidewall which cooperatively with the top plate and the base plate defines an internal volume. A plurality of plates are axially positioned in the internal volume between the top plate and the base plate. Each plate defines a plate opening axially aligned with the first opening which cooperatively with the first opening and a portion of the base plate, defines an internal cavity for housing a filter element. The plates define a first set of fluid channels structured to deliver a lubricant to the internal cavity, and a second set of fluid channels structured to provide a coolant around the first set of fluid channels.
