| 20090001004 | Vibration isolation for filtration equipment - A filter is described that is combined with a device to address vibrations. Such vibrations can adversely impact filter performance. An engine system including this combination is also described. | 01-01-2009 |
| 20090001005 | Filter system with vibration dampening - A filter is described that is combined with a device to address vibrations. Such vibrations can adversely impact filter performance. An engine system including this combination is also described. | 01-01-2009 |
| 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 |
| 20090057219 | Replaceable filter elements including unique interfaces and filtration systems including same - One embodiment is a replaceable filter element including a filter media having a first end, a second end and an interior cavity, and an endplate coupled to the first end of the filter media, the endplate including a projection extending from the endplate, the projection including a first portion, a flange and a second portion, the first portion extending from the endplate to the flange, the second portion extending from the flange. Further embodiments, forms, objects, features, advantages, aspects, and benefits shall become apparent from the following description and drawings. | 03-05-2009 |
| 20090090668 | FUEL FILTER ASSEMBLY WITH FLOW RESTRICTION VALVE - A “no filter, no run” filtration system that is designed to verify that an appropriate filter cartridge is installed. A flow control valve is provided on a standpipe to control the flow of fuel into the standpipe. The valve has a component that has a first position at which any flow through the flow passage past the valve is insufficient to permit engine operation, and a second position at which a greater amount of flow through the flow passage is permitted by the valve in an amount sufficient to permit engine operation, and the component rotates about the longitudinal axis when it moves from the first position to the second position and from the second position to the first position. | 04-09-2009 |
| 20090114588 | FUEL FILTER ASSEMBLY WITH FLOW RESTRICTION SLEEVE - A “no filter, no run” filtration system that is designed to verify that an appropriate filter cartridge is installed. A flow control sleeve is provided on a standpipe to control the flow of fluid, for example fuel, into the standpipe. The sleeve can be axially moveable between closed and open positions, with one or more members on an installed filter cartridge designed to release the sleeve to permit the movement from the closed position to the open position to allow fluid flow. A spring acts on the sleeve to bias the sleeve back to the closed position upon removal of the filter cartridge. The sleeve can also be designed without axial movement, but nonetheless is configured to be opened and closed to control fluid flow into the standpipe. | 05-07-2009 |
| 20090242475 | REPLACEABLE FUEL FILTER ELEMENTAND FUEL FILTER ASSEMBLY - One embodiment is a unique replaceable filter element. Further embodiments, forms, objects, features, advantages, aspects, and benefits shall become apparent from the following description and drawings. | 10-01-2009 |
| 20090249754 | Replaceable filter cartridge with removal feature - A replaceable filter cartridge including filter media defining a substantially columnar flow path sandwiched between first and second endcaps. The first endcap includes an opening fluidly connected to the substantially columnar flow path, leading to an interior cavity of the filter media defining a flow path. A sealing flange is aligned with the opening and extends axially away from the filter media. A handle is coupled to the sealing flange or a centerpost such that at least a portion of the handle extends into the flow path. | 10-08-2009 |
| 20090250388 | FILTRATION DEVICE WITH RELEASABLE ADDITIVE - A filtration device is provided that includes a filter component and an additive component. The filter component includes concentrically arranged filtering elements disposed in a filter-in-filter configuration. The additive component includes at least one additive material that is introduced into a working fluid to be filtered. The filter component and additive component provide an assembly for a filtration system that would filter a variety of working fluids. The filter component and additive component provides an assembly that can filter fluids more efficiently. As a result, fluids may enjoy, for example, extended drainage intervals and thereby reduce component wear. | 10-08-2009 |
| 20100044298 | Centertube for a combination full flow and bypass filter apparatus - A filter apparatus for filtering fluid in an internal combustion engine, the filter apparatus including annular full flow filter media extending axially between a first end and a second end. The full flow filter media surrounds a reinforcing member which extends axially between the first end and the second end and includes a plurality of axially spaced apart circumferential connecting segments. The circumferential connecting segments extend between a plurality of substantially axially extending ribs which connect the reinforcing member to a radially inwardly spaced bypass tube. The reinforcing member also includes a plurality of flow apertures defined by the connecting segments and the ribs. | 02-25-2010 |
