A filtration system having an undulated interlocking housing-endplate interface geometry is described. In the filtration system, a filter element endplate and a filter housing component (e.g., a shell housing, a filter mounting head, etc.) meet at an interface. The filter housing component includes an undulating or repeating pattern that meshes with a matching undulating or repeating pattern on the endplate of the filter element. The undulating or repeating pattern prevents the filter element from freely rotating with respect to the filter housing component of the filtration system.

Undulated interlocking housing-endplate interface geometry

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 ().

Filter cartridge endplate with integrated flow structure

A filter assembly that comprises a housing, an outer filter element, and an inner filter element. The outer filter element is positionable within the housing and comprises an outer filter media. The inner filter element is positionable within the outer filter element and comprises an inner filter media, a media support structure, an inner top endplate, and an inner bottom endplate. The inner top endplate comprising a top rib that extends continuously around a portion of a top surface of the inner top endplate.

A fuel water separator filter is configured as a filter-in-filter construction with multiple water separating layers to separate water from the fuel. The fuel water separator filter is configured for use on a suction side of a fuel pump, and includes a neck with a radially outward facing seal that in use seals with the filter housing. The filter housing is formed with an isolated water sump that in use is isolated from water that is stripped from the fuel by the first stage of the outer filter.

Fuel water separator filter with an improved sealing arrangement

A fuel filter system that does not require the periodic draining of a water sump. The system includes a fuel tank for storing fuel and a fuel filter fluidly coupled to the fuel tank for separating water from the fuel. A fuel pump has a suction side and a high pressure side. The high pressure side of the fuel pump is fluidly coupled to the fuel filter for pumping fuel to the fuel filter. A water emulsifier, such as an orifice, is fluidly coupled to the fuel filter to receive water and fuel from the fuel filter and form a water-fuel emulsion. The water-fuel emulsion is supplied to any point in the system on the suction side of the fuel pump, such that the water-fuel emulsion passes through the fuel pump and fuel filter.

Facial sealing system for a filter

A fuel filter assembly for filtering a fuel-liquid mixture comprises a filter cartridge and a return tube. The filter cartridge comprises a filter media and a housing. The filter media defines an open central region therein. The housing contains the filter media. The return tube extends into the central region of the filter media. The return tube collects and drains liquid from a bottom inner region of the filter media.

A no filter no run (NFNR) fluid filter and fluid filter assembly are provided. The NFNR fluid filter assembly includes a fluid filter, a filter head or filter housing, and a bypass flow path. The bypass flow path may be sealed off when a compliant filter is installed. When a non-compliant filter is installed (a filter without a bypass seal), fluid may flow to the bypass flow path.

No filter no run fluid filter with integration of low pressure fluid system

A 'no filter, no run' filtration system that is designed to verify that a filter cartridge is present to safe-guard against damage to fuel injectors, associated fuel components, etc. and engine malfunctions. Fuel flow to the engine is prevented altogether or permitted in an amount insufficient to allow engine operation if a filter cartridge is not installed, and an appropriately designed filter cartridge is required to be used in order to permit sufficient fuel flow for engine operation. In one embodiment, a flow restriction valve is provided that includes a ball.

A no filter no run (NFNR) fluid filter and fluid filter assembly are provided. The NFNR fluid filter assembly includes a fluid filter, a filter head or filter housing, and a bypass flow path. The by-pass flow path may be sealed off when a compliant filter is installed (a filter without a bypass seal), fluid may flow to the bypass flow path.
