A mechanism, for example crush ribs, connects an upper end plate of the outer filter and an upper end plate of the inner filter to prevent relative axial and radial movement therebetween when assembled. Relative axial or radial motion can create a rattling noise which is sometimes perceived as a low quality filter. The crush ribs are, for example, formed on an interior surface of the upper end plate of the outer filter, and the ribs engage an outer perimeter of the upper end plate of the inner filter. One or more of the ribs crush when the inner filter is installed into the outer filter to ensure tight axial and radial engagement between the filters. | 03-12-2009 |
| 20090065419 | FILTER CARTRIDGE WITH SNAP FIT CONNECTION - A filter cartridge for use in filtering fluids, for example fuel, lubrication, hydraulic and other liquids, as well as air. The filter cartridge is a filter-in-filter design with an inner filter and an outer filter. The inner filter and the outer filter, for example the bottom end plates thereof, are connected to each other via a snap fit connection mechanism. During manufacture, the inner filter can be inserted into the outer filter, with the snap fit connection mechanism retaining the inner filter in the outer filter. | 03-12-2009 |
| 20090050554 | FILTER CARTRIDGE WITH FLOW PASSAGE IN END PLATE - A filtration system, for example a fuel filtration system in an engine, that helps prevent engine operation when there is no filter cartridge installed or a non-recommended and/or inferior filter cartridge is installed. The filter cartridge includes first and second endplates, one of which includes a fluid flow passage therein through which fluid can flow. The flow passage connects the clean fluid from the filter to a clean fluid outlet. | 02-26-2009 |
| 20090045109 | FLOW CONTROL VALVE WITH PLATE SPRING FORCE ACTUATION - A filter cartridge with a valve actuating protrusion having a sliding surface that is configured to engage with a valve, with the sliding surface being tapered so that a first portion of the sliding surface that engages the valve is wider than a second portion of the sliding surface that engages the valve, and the sliding surface is configured so that the first portion engages the valve before the second portion. The valve, which can be in any fluid passage of a filter housing, includes a plurality of spring arms. Engagement between the spring arms and the sliding surface creates a lifting force which opens the valve. | 02-19-2009 |
| 20090020465 | STANDPIPE WITH FLOW RESTRICTION VALVE, AND FILTER CARTRIDGE - 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. | 01-22-2009 |
| 20090014381 | FLUID FILTER WITH LOCALIZED FLOW ATTACHMENT - A fluid filter device is described, where a flow attachment member provides a unique interface between the filtering element and a filter head. The fluid filter described herein generally provides a flow structure that is localized and sealed. The flow attachment member is configured to communicate fluid into and out of the fluid filter, and is configured to localize fluid flow both into and out of the fluid filter within a separating structure of the flow attachment member. The flow attachment member further includes a seal structure configured to substantially prevent or at least confine leakage to a localized area away from proximity of the edges of the housing. | 01-15-2009 |
| 20090007553 | PREVENTION OF FACE-PLUGGING ON AFTERTREATMENT DEVICES IN EXHAUST - An inlet face for an aftertreatment device that prevents and/or eliminates face-plugging for a passageway where the inlet face is disposed. The inlet face includes a particular end surface disposed on an outer surface at the end of a substrate. The end surface includes at least one of a three-dimensional topographical configuration disposed at the end of the substrate, a chemical coating applied on the end of the substrate, or both a three-dimensional topographical configuration disposed on the end of the substrate and a chemical coating applied on the three-dimensional topographical configuration. As one example, the inlet face can be helpful in preventing carbonaceous fouling, which can result from engine exhaust material, such as carbon soot and other engine exhaust by-products. | 01-08-2009 |
| 20080308481 | DRAIN VALVE FOR FILTER SERVICE AND METHOD - A fluid filter is described, where a drain valve is configured to move back and forth into open and closed positions. The drain valve and a filter cartridge are in a structural arrangement such that the drain valve is put in an open position before the filter and/or a filter element therein can be serviced or replaced. | 12-18-2008 |
| 20080302717 | MULTI-LAYER FILTER INCLUDING RETAINERS - A multi-layer filter including a first media layer surrounded by a second media layer, a third media layer surrounding the second media layer, and at least one retainer disposed between the first and second media layers or between the second and third media layers. The first, second and third media layers surround the central axis of the filter. The filter has multiple media layers in a compact package, providing increased media surface area which allows greater contaminant holding capacity, lower pressure drop, and lower face velocity. | 12-11-2008 |
