A mechanical interlock system for a fluid filter is described herein. The mechanical interlock system may include a filter cartridge and a filter cartridge manifold for receiving the filter cartridge. The filter cartridge may include a filter body, a fluid inlet and outlet, and an integrated locking head. The integrated locking head may include a key extending radially outward from the integrated locking head and channels on an outer surface of the integrated locking head. The filter cartridge manifold may include an insertion and extraction tube for receiving the key and latching mechanisms. The insertion and extraction tube may include a primary keyway and a secondary keyway. The key, keyways, latching mechanisms, and/or channels may interact to maintain alignment of the filter cartridge during insertion of the filter cartridge into an appliance including the filter cartridge manifold.

A fuel filter assembly includes a filter housing defining a cavity, a center stack having a base component and a top portion. The center stack is positioned within the cavity of the filter housing and attached to the housing, the center stack having an axial aperture in the top portion, the axial aperture having a circumferential surface, and a fuel filter. The fuel filter includes a filter base, an end cap having a top surface and a bottom surface opposite the top surface, an axial extension that extends from the bottom surface, and at least one prong attached to the axial extension, the at least one prong having an axial surface facing away from the top surface that axially locates the fuel filter in the housing against the circumferential surface, a filter element attached to the bottom surface of the end cap, and a pin attached to a filter base.

A fuel filter assembly includes a filter housing that forms a cavity, and a center stack. The center stack is positioned within the cavity and includes an axial aperture in the top portion, the axial aperture having a circumferential surface, and a fuel filter. The fuel filter includes a filter center support. The fuel filter also includes a sword positioned along a surface of the filter center support, an end cap, a filter element attached to an undersurface of the end cap, a water separator at a filter base of the fuel filter, and a pin attached to the water separator. When the fuel filter is positioned within the filter housing, the sword engages with a slot of a center stack of the fuel filter housing and the pin aligns with a channel of the housing.

An air cleaner assembly is disclosed. In one aspect, the air cleaner assembly includes a housing defining an inlet and an outlet, and including an access opening between the inlet and outlet. The air cleaner also includes a filter cartridge received within the housing and covering the access opening. The air cleaner also includes a lock mechanism. The lock mechanism is movable between an unlocked position in which the filter cartridge can be installed and removed from the housing and a locked position in which the filter cartridge is secured within the housing. The filter cartridge and lock mechanism include interacting features allowing the lock mechanism to be moved from the unlocked position to the locked position only when the filter cartridge is installed within the housing.

An oil sequestering, air-drying cartridge device comprises a pair of tandem fluid diodes for respectively preventing backflow of moist air into an oil coalescing filter and preventing backflow of dry air into a desiccant material. The device comprises an outer cartridge skin and a middle shell concentrically nested between the cartridge skin and an inner shell. The middle shell houses channel walls having offset wave-like contours that prevent backflow of moist air into the oil filter, and the inner shell comprises similar channel walls that prevent backflow of dry air into the desiccant, which is positioned between the inner and middle shells.

An oil separator is provided and includes an exterior shell defining a first interior and first and second openings fluidly communicative with the first interior, a distributor and first and second filter media cartridges. The distributor is integrated within the exterior shell to define a second interior within the first interior, has a length, which is slightly less than that of the exterior shell, being disposed to define opposite spaces between opposites ends thereof and opposite ends of the exterior shell and is sealed to the exterior shell along the length to form first and second passageways from the first opening to the opposite spaces. The first and second filter media cartridges are disposed within the first interior between the opposite spaces and the second opening.

An air filter cartridge (1) for an air intake system for a vehicle engine extends along a main axis (X-X). The air filter cartridge includes a filter element (5), suitable to filter the air sucked through the filter eleemtn and having extension along the main axis (X-X) and an internal structure (3) that extends inside of the filter element (5). The internal structure (3) identifies a plurality of ducts (30) fluidically independent from each other through which the filtered air flows separately. Each duct (30) extends between an inlet mouth (31), placed in proximity of a respective filter element portion (51), and an outlet mouth (32) placed in proximity of the head element (2) in such a way as to induce the intake of air through each duct (30) through the respective portion of the filter element (51).

An oil filter assembly for an integrated drive generator is disclosed, which includes an elongated cylindrical filter element having opposed upper and lower end portions, a longitudinal axis, an outer diameter and an inner diameter, wherein the oil filter assembly that includes the filter element has an axial length that is greater than 4.60 inches.

A water separation group is for a fuel filtration and separation assembly of a vehicle fuel circulation system. The assembly includes an assembly casing extending along a longitudinal axis positionable in the vehicle in a horizontal position and accommodating a filtration group for filtering dirty fuel. The water separation group is positionable in the assembly casing in fluidic connection with the filtration group and extends along a main axis parallel to and/or coincident with the longitudinal axis. The water separation group includes a separator and a blocking device below the separator to prevent return of separated water to the separator. The blocking device includes a blocking surface extending longitudinally forming an angle with the direction of the main axis that inclines at least a portion of the blocking surface to allow water separated from the fuel to flow towards the wall from which the blocking surface extends.

A water filter cartridge has an end cap with inlet and outlet nozzles extending from the end cap. A lateral support extends laterally from at least one of the nozzles. A projection extends from the lateral support toward a receiving manifold to cooperate with the manifold during use. The lateral support is offset from the end cap so the projection is vertically offset from an end of the cartridge and laterally offset from and supported from the nozzles.
