Abstract: A filtration system is described. The filtration system includes a filter housing having a central tube and a replaceable filter element. The central tube includes a gasket that plugs a passage from the dirty side of the filter element to the clean side of the filter element when the filter element is installed in an operational position. The gasket includes an integrated drain extending through the gasket. The gasket is integrated into the central tube and stays in place when the filter element is removed (e.g., during replacement of the filter element). The removal of the filter element opens the drain to allow for the draining of the fluid from the housing to the tank. The gasket is reusable and does not need to be replaced with each filter element replacement.

Abstract: A filtration assembly includes a filter housing and a filter element. The filter housing includes a base and a cover including an underside having one or more retainer features. The cover is removably coupled to the base. The filter element is removably installed within the base when the cover is coupled to the base. The filter element includes filter media and an endplate coupled to one end of the filter media. The endplate includes an outer perimeter and one or more engagement features protruding from the outer perimeter. The one or more engagement features engage the one or more retainer features in the cover upon installation of the endplate into the cover, thereby coupling the endplate to the cover.

Abstract: A filtration assembly includes a housing. The housing includes a first housing for fluid and a second housing opening for fluid. A containment cover is removably coupled to the housing. The containment cover defines a cover opening, a cover surface, and a flow passage. The cover opening is in fluid communication with the housing. The cover surface is substantially continuous around a circumference of the containment cover. The cover surface includes an open portion in fluid communication with the second housing opening. The flow passage is formed by a first passage surface and a second passage surface. The flow passage includes a first end in fluid communication with the cover opening. A second end is in fluid communication with the second housing opening through the open portion of the cover surface. The flow passage extends radially outward from the cover opening.

Abstract: 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.

Abstract: A replacement filter element having a removable pin attached to the filter elements is described. The removable pin is attached to the filter element via a first interference fit. When the replacement filter element is installed into a filtration system having a drain valve with an internal draft, the removable pin seals onto the drain valve and forms a second interference fit between the drain valve and the pin. The pin seals an opening in the drain valve. The second interference fit is stronger than the first interference. Accordingly, when the replacement filter element is removed from the filter housing (e.g., during a service event of the replacement filter element), the pin detaches from the replacement filter element and remains positioned within the drain valve thereby preventing fluid from leaking from the housing when the filter element is removed. The pin permanently plugs the drain valve once installed.

Abstract: According to a set of embodiments, the filtration system includes a housing with a fuel inlet and a fuel outlet. A pump is in fluid communication with the fuel outlet. A fuel tank is in fluid communication with the fuel inlet. A thermal recirculation valve includes a thermal recirculation valve inlet and a thermal recirculation valve outlet. The thermal recirculation valve inlet receives heated fuel and the thermal recirculation valve outlet is in fluid communication with the fuel tank. A fluid passage is between the thermal recirculation valve inlet and the thermal recirculation valve outlet. A passage blocking mechanism having a first position and a second position. The passage blocking mechanism is structured to prevent fluid flow through the fluid passage when in the first position. The passage blocking mechanism is structured to allow fluid flow through the fluid passage when in the second position.

Abstract: No-filter no-run filtration systems are described. The filtration systems include a valve positioned within a filter housing. The valve is normally biased in a closed position when a filter cartridge is not inserted into the filter housing such that from within the filter housing cannot flow to an internal combustion engine. The filter cartridge includes a main filter element and a hydrophobic screen assembly. The hydrophobic screen assembly includes a valve interaction pin that interacts with and opens the valve when the hydrophobic screen assembly is received in the filter housing in an operating position. Accordingly, fuel can only flow from the filter housing to the fuel injectors when the hydrophobic screen is received within the housing in an operating position. The hydrophobic screen is a separate component from the main filter element allowing for independent replacement of the main filter element and the hydrophobic screen.

Abstract: A filter cartridge for use within a filter housing of a filter assembly that includes a filter media, a first endplate attached to a first end of the filter media, and a second endplate attached to a second end of the filter media. The second endplate includes a plurality of extensions extending axially away from a surface of the second endplate. The plurality of extensions possess a toothed profile and are sized and positioned so as to engage with at least one rib associated with a portion of the filter housing such that, when at least one of the plurality of extensions is engaged with the at least one rib, a rotation of the portion of the filter housing in a first direction results in a corresponding rotation of the filter cartridge.
