摘要： A self-driven centrifuge for separating particulate matter out of a circulating liquid includes a base plate and a rotor shell. The base plate has a center tube extending therefrom along a longitudinal axis. The center tube is constructed and arranged to deliver fluid containing particulate matter. A rotor shell has an inner cavity and a plurality of spiral vanes extending along the longitudinal axis within the inner cavity. The spiral vanes extend spirally around the center tube and the spiral vanes are integrally formed with the rotor shell. In one form, spiral vanes are also formed on the base plate and are nested in between the spiral vanes of the rotor shell.

摘要： A cone-stack centrifuge for separating particulate matter out of a circulating liquid includes a cone-stack assembly which is configured with a hollow rotor hub and is constructed to rotate about an axis. The cone-stack assembly is mounted onto a shaft centertube which is attached to a hollow base hub of a base assembly. The base assembly further includes a liquid inlet, a first passageway, and a second passageway which is connected to the first passageway. The liquid inlet is connected to the hollow base hub by the first passageway. A bearing arrangement is positioned between the rotor hub and the shaft centertube for rotary motion of the cone-stack assembly. An impulse-turbine wheel is attached to the rotor hub and a flow jet nozzle is positioned so as to be directed at the turbine wheel. The flow jet nozzle is coupled to the second passageway for directing a flow jet of liquid at the turbine wheel in order to impart rotary motion to the cone-stack assembly. The liquid for the flow jet nozzle enters the cone-stack centrifuge by way of the liquid inlet. The same liquid inlet also provides the liquid which is circulated through the cone-stack assembly.

摘要： A bypass circuit centrifuge for separating particulate matter out of a circulating liquid includes a hollow and generally cylindrical centrifuge bowl which is arranged in combination with a base plate so as to define a liquid flow chamber. A hollow centertube axially extends up through the base plate into the hollow interior of the centrifuge bowl. The bypass circuit centrifuge is designed so as to be assembled within a cover assembly and a pair of oppositely disposed tangential flow nozzles in the base plate are used to spin the centrifuge within the cover so as to cause particles to separate out from the liquid. The interior of the centrifuge bowl includes a plurality of truncated cones which are arranged into a stacked array and are closely spaced so as to enhance the separation efficiency. The stacked array of truncated cones is sandwiched between a top plate positioned adjacent to the top portion of the centrifuge bowl and a bottom plate which is positioned closer to the base plate. The incoming liquid flow exits the centertube through a pair of oil inlets and from there flows through the top plate. The top plate in conjunction with ribs on the inside surface of the centrifuge bowl accelerate and direct this flow into the upper portion of the stacked array of truncated cones. As the flow passes through the channels created between adjacent cones, particle separation occurs as the liquid continues to flow downwardly to the tangential flow nozzles.

摘要： 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.

摘要： A filter within a filter cartridge design is described that includes a sealing structure on an endplate of an outer filter element. Generally, the sealing structure includes an annular flange on the endplate that can directly seal against an interior surface of a housing when the filter cartridge is assembled for use. During filtration, the annular flange prevents a working fluid from bypassing the outer filter element. The sealing flange can seal with the housing in a press fit engagement.

摘要： A disposable, spin-on fluid filter for mounting to a fluid-directing head includes a molded housing having a closed base and a sidewall defining a hollow cavity. Filtering media is positioned within the hollow cavity and a nutplate is joined to the housing so as to enclose the filtering media. The nutplate includes a plurality of inlet flow openings and a lobed sleeve extending into the filtering media. An endplate is joined to the filtering media including a flange portion and a sleeve portion. The fluid filter includes an elastomeric valve having a first portion positioned between the flange portion and the inlet flow openings and a second portion positioned between the sleeve portion and the lobed sleeve. The valve provides an anti-drain back capability and in cooperation with the lobed sleeve provides a filtering media by-pass capability.

摘要： A filter assembly is described that includes a unique seal configuration between a filter and a housing. The filter has a filter media that allows fluid to be filtered therethrough, and has an endplate with an opening that allows fluid to flow into or out of the filter media. The endplate has a main surface with an elliptical spud protruding outward from the main surface and surrounding the opening. An oval seal is disposed about an outer surface of the elliptical spud. The housing is releasably connected to the filter, and has a mounting component. The mounting component has an elliptical boss that mates with the elliptical spud and seals against the oval seal.
