Abstract:
The present invention provides a filter apparatus for removing impurities contained in a fluid that includes a housing (1), a full flow filter contained in the housing, the housing and the full flow filter (8) arranged such that the entirety of the fluid to be filtered by the filter apparatus passes through the full flow filter (8), a bypass filter (15), and a conduit (16) which contains a pressure reduction section (51). The full flow filter (8), bypass filter (15), and conduit (16) positioned within the housing (1) such that the bypass filter (15) is positioned downstream of the full flow filter (8) and the pressure reduction section (51) is arranged to create a pressure differential across the bypass filter (15) such that a predetermined portion of the fluid to be filtered by the filter apparatus passes through the bypass filter (15). The invention further provides a method of removing impurities contained in a fluid by filtration by introducing a fluid to a filtering apparatus including a full flow filter (8) and a bypass filter (15); filtering 100% of the fluid with the full flow filter (8); creating a pressure differential across the bypass filter (15) whereby a predetermined portion of the fluid filtered by the full flow filter is drawn through the bypass filter (15), thereby filtering the predetermined portion of the fluid a second time.

PROBLEM TO BE SOLVED: To provide a filter system having a filter element ejection device. SOLUTION: The filter system may include an ejector receiver for receiving actuation action from an ejector of a filter housing. The ejector is engaged with the ejector receiver when a user desires to eject the filter element from the filter housing. Typically, the ejector extends through the filter housing and ejects the filter element from the housing, in the axial direction. COPYRIGHT: (C)2010,JPO&INPIT
Abstract:
A liquid reclamation assembly is provided for processing a lubricant or other liquid. The assembly includes a housing interior for receiving a filter subassembly. A manifold is in fluid communication with a discharge region of the filter subassembly, the manifold comprising a primary manifold passage for passage of source fluid and a series of draw ports. The cross sectional area of the primary manifold passage is greater than the total cross sectional area of the series of draw ports to create a venturi effect to draw fluid through the assembly. The filter subassembly includes a series of target filtration segment, each segment being designed for a specific reclamation process. An entry manifold governs and distributes the fluid to each of the target filtration segments. Results of an analysis of the fluid can be used to determine which target filtration segments are desired for processing the fluid. Valves within the entry manifold can direct the flow accordingly.
Abstract:
A filter system having a filter element ejection device is provided. Filter systems according to the present invention may include a filter element that includes an ejection receiver for receiving actuation action from an ejector of a filter housing. The ejector engages the ejection receiver when a user desires to eject the filter element from the filter housing. Typically, the ejector extends through the filter housing and axially ejects the filter element from the housing.
Abstract:
A bypass filter cartridge is provided having a low efficiency filter element and a high efficiency filter element oriented in either parallel or series. The low efficiency filter element may comprise pleated filter sheet while the high efficiency filter element may include a tubular ring of depth media with considerable thickness or pleated media of varying types. The filter cartridge may be adapted and configured for use in specialized locomotive oil lubrication circuits with substantial benefit therein.
Abstract:
A debris catcher uses induced circulation from a venturi to urge debris laden flow into the lower end of a housing. An inlet tube maintains velocity so as to keep the debris moving with the fluid stream as it goes up the inlet tube. A screen fits over the open end of the inlet tube and runs down around the inlet tube toward the entrance of the debris laden fluid into the lower end of the housing. There is a clearance around the cylindrical portion of the screen so some flow can exit that way. There is also an open exit through the top of the screen that can be reached after the fluid stream makes two hairpin turns. Many modules can be stacked. Each module has a large screen area for flow to exit and progressive modules can have smaller screen openings in an uphole flow direction.
Abstract:
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.
