An internal combustion engine crankcase ventilation rotating coalescer includes an annular rotating coalescing filter element, an inlet port supplying blowby gas from the crankcase to the hollow interior of the annular rotating coalescing filter element, and an outlet port delivering cleaned separated air from the exterior of the rotating element. The direction of blowby gas is inside-out, radially outwardly from the hollow interior to the exterior.

Disclosed are modular filter-in-filter elements, namely an outer filter element and an inner filter element which may be assembled to form a filter cartridge for use in separation methods and systems. The outer filter element typically functions as a coalescing element and the inner element typically functions as a particulate filter element. The disclosed filter cartridges may be structured for separating water from a hydrocarbon-based liquid fuel as the fuel moves through the cartridge from outside to inside.
摘要:
A water separator and particulate filter with a first or outer stage configured to coalesce water from fluid such as fuel, and a second or inner stage configured to separate coalesced water from the fluid and also remove fine solid contaminants from the fluid. The coalescing stage includes a pleated cylinder of polymeric media. The pleated cylinder has pleat valleys and downstream pleat tips, and release sites defined at the downstream pleat tips. The separator stage includes a non-pleated cylinder of polymeric media surrounding and in contact with outer pleat tips of a multi-layer pleated cylinder.

An internal combustion engine gas-oil separator is provided by one or more rotative inertial impactor separators in an interior chamber of the engine and mounted to a rotating engine shaft in such interior chamber.
摘要:
An inertial gas-liquid separator and method is provided, including variable orifice jet nozzle structure having a variable orifice area dependent upon axial movement of a plunger relative to a housing sleeve, and in another embodiment having first and second flow branches, with the first flow branch being continuously open, and the second flow branch having a variable flow controller controlling flow therethrough.
摘要:
A coalescer has variable characteristics including variable diameter of individual fibers along their length such that an individual fiber has differing diameters at different points along its length, and including variable porosity.
摘要:
A filter (102) for filtering fluid from a machine (104) includes a filter housing (106, 250) having a first inlet (114) receiving a first fluid from the machine, a first outlet (116) returning the first fluid to the machine, a second inlet (118) selectively receiving a second fluid from a source (120) of cleaning fluid, and a second outlet (122) for exhausting the second fluid and for exhausting the first fluid from the dirty side of the main filter element (124) in the housing backwashed by the second fluid. The filter housing has a first flow path (126) therethrough from the first inlet then through the filter element in one direction then to the first outlet, and has a second flow path from the second inlet then through the filter element in the opposite direction then to the second outlet, the first and second flow paths having common but opposite direction portions through the filter element. A second filter element (156) is provided in the second flow path.
