  • Publication number: 20210086115
    Abstract: A filter cartridge endplate (12) 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 (12), where a separator (10) is built into the endplate (12) the separates fluid flow. The endplate (12) includes a plate with a major surface, a separator (10) that protrudes axially away from the major surface. The separator (10) includes a first flow portion (14) and a second flow portion (16), where the first flow portion (14) is disposed radially inward relative to the second flow portion (16). The first flow portion (14) includes a channel (22) and the second flow portion includes a channel (24). The respective channels (22,24) 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 (12).

  • Publication number: 20180214803
    Abstract: A filter cartridge is provided that is designed to actuate a valve that controls fluid flow into an outlet for discharging filtered fluid. The valve receives a ball at a first position which is axially movable between the first position and a second position. If a filter cartridge is not installed or an inappropriately designed filter cartridge is installed, the ball is moved from the first position to the second position to seal an outlet opening of the outlet. If the described filter cartridge is installed, the ball is retained at the first position by a holding member and the valve allows filtered fluid flow into the outlet opening.

  • Publication number: 20170335812
    Abstract: Fuel filtration systems having an automatic drain assembly for water that accumulates in the filter housing are described. The filtration system includes a filter media that is configured to remove particulate matter and dispersed water contained within the fuel. The water is drained to a drain reservoir within the filter housing where the water collects. When the water reaches a threshold level, a controller initiates a warning to the engine operator, such as a dashboard light, that instructs the operator to shut the engine off. When the engine is shut off, the collected water is drained through a valve of the automatic drain assembly. In some arrangements, the automatic drain assembly can be retrofitted to existing fuel filtration systems thereby reducing the cost of fitting the automatic drain assembly to existing internal combustion engines.
