A spin-on fluid filter with improved attachment and sealing with the filter head. The filter has a gasket positioned at the end of threads used to connect the filter to a filter head. The described design protects the gasket from excessive engine heat, cut or tear damage during installation, and the roll out effect of installation torque. In addition, the described attachment provides gasket protection and uniform compression of the gasket. The gasket can be any type that provides a seal which keeps external threads on the filter and the filter head dry.

A filtration system comprises a housing and a shell housing removably coupled to the housing. A valve comprise a valve housing and a plunger. The plunger comprises a seal member structured to seal an opening in the valve housing. The plunger is axially movable between a closed position, in which the seal member seals the opening, and an open position, in which the seal member does not seal the opening, thereby permitting fluid to flow through the valve housing. A filter element comprises filter media and an endcap. The endcap comprises an alignment tab configured to rotationally secure the filter element with respect to the shell housing when the shell housing is received in the housing. The endcap comprise a valve interaction projection structured to transfer rotation of the filter element and the shell housing to the plunger during installation of the filter element.

A filter cartridge endplate () is described herein that has a integrated flow structure. For example, the integrated flow structure has concentric flow portions disposed at a center of the endplate (), where a separator () is built into the endplate () the separates fluid flow. The endplate () includes a plate with a major surface, a separator () that protrudes axially away from the major surface. The separator () includes a first flow portion () and a second flow portion (), where the first flow portion () is disposed radially inward relative to the second flow portion (). The first flow portion () includes a channel () and the second flow portion includes a channel (). The respective channels () ae configured to allow axial fluid flow relative to the plate, and configured to allow fluid flow that is localized toward the center of the plate ().

Torsional no filter no run system and method

A filter assembly comprising a housing defining an internal volume. The housing comprises a first coupling member formed in a housing first end of the housing. The housing first end is threadless. The filter assembly further comprises a filter head. The filter head comprises a first thread formed on a surface thereof. The filter assembly further comprises an adapter. The adapter comprises a second coupling member formed on an adapter first end of the adapter. The second coupling member engages the first coupling member formed in the housing first end so as to removably couple the adapter and the housing. A second thread is formed on the adapter first end. The second thread engages the first thread formed in the filter head so as to removably couple the adapter and the filter head.

A valve-sensor assembly for a filter assembly that filters water from a fluid. The valve-sensor assembly includes a sensor body and a drain valve body. The sensor body includes a filter element engagement portion having a hollow interior that extends longitudinally through a length of the sensor body and a protrusion that extends circumferentially along an exterior surface of the filter element engagement portion. The sensor body further includes one or more water-in-fluid sensors provided at the exterior surface of the filter element engagement portion. The drain valve body includes a main body having a drain port, and a valve extending from the main body and extending at least partially within the hollow interior. The valve has an interior passage in fluid communication with the drain port.

A filter cartridge endplate () is described herein that has an integrated flow structure. For example, the integrated flow structure has concentric flow portions disposed at a center of the endplate (), where a separator () is built into the endplate () that separates fluid flow. The endplate () includes a plate with a major surface, it separator () that protrudes axially away from the major surface. The separator () includes a first flow portion () and a second flow portion (), where the first flow portion () is disposed radially inward relative to the second flow portion (). The first flow portion () includes a channel () and the second flow portion includes a channel (). The respective channels () are configured to allow axial fluid flow relative to the plate, and configured to allow fluid flow that is localized toward the center of the plate ().

A filter cartridge is provided. The filter cartridge includes a first end plate connected to a first end of a filter media, a second end plate connected to a second end of the filter media and a centering device. The centering device is located towards the second end of the filter media for aligning a pin of the first end plate into a hole of a filter housing. The centering device also includes first ribs at first opposing ends of the centering device and second ribs at second opposing ends of the centering device, the first and second ribs protruding inwardly toward the center of a centering device hole. The length of the first ribs towards the center of the centering device hole and the length of the second ribs towards the center of the centering device hole are designed to align with a cross-sectional shape of the standpipe hole.

A mounting assembly is described that has an interface designed to increase the stress margin of at least the module side of the assembly, for example in a liquid filtration module, and to increase ease of assembling its mounting components. The interface reduces the failure of the mounting assembly at least on the module side, so that if failure of the mounting assembly occurs, such an occurrence is less likely to be at the interface and on the module side, thereby reducing the need to replace more complex and expensive components that may be on the module side. Generally, the mounting assembly includes a mounting interface and a mounting bracket connectable to the mounting interface. A retention component is configured to maintain connection of the mounting interface to the mounting bracket.

Various 'no filter, no run' fuel filtration designs are described that include a variable restriction orifice (VRO) designed to vary the amount of fluid, for example fuel, that reaches a fluid outlet. The VRO has a fully open position at which a maximum non-zero fluid flow is permitted, and a fully closed position at which a limited amount of fluid can flow to the outlet. In the case of diesel fuel, the amount of fuel flow permitted at the fully closed position provides lubrication of downstream fuel system components, for example the fuel pump, but is insufficient to permit engine operation.
