Abstract:
A filter assembly where the filter element is designed to connect directly to the spud of a vehicle fluid system, for example an engine lubrication system, a fuel system, or a hydraulic system. This provides a direct connection between the filtered fluid and the fluid system. The need for a seal between the top endplate and the nutplate, as well as the coil spring within the shell, which are found in conventional spin-on filter assemblies can be eliminated, which reduces inventory and the number of parts forming the filter assembly, and facilitates manufacturing of the filter assembly.
Abstract:
A combination full flow media and bypass media filter cartridge for filtering fluid in an internal combustion engine. The apparatus includes a venturi filter having a full flow media attached to and extending between a first endplate and a second endplate. The second endplate includes an orifice. The apparatus further includes a stack of disks extending between a compression end and a venturi end. The stack of disks has a flow path defined by a plurality of openings wherein each disk includes at least one opening. The flow path extends between the compression end and the venturi end. The venturi end is substantially adjacent the second endplate of the venturi filter. The apparatus further comprises resilient compression member connected to the venturi filter for maintaining a minimum sealing force on the stack of disks.
Abstract:
A filter assembly where the filter cartridge is secured to the nutplate and a seal is provided between the filter cartridge and the nutplate. The sealing relationship between the filter cartridge and the nutplate is maintained during use of the filter assembly without using a spring engaged with the filter cartridge that biases the filter cartridge into engagement with the nutplate.
Abstract:
A fluid filter includes a filter element having a filtering media disposed between two endplates. One endplate includes an open flow passage that allows a working fluid to flow into or out of the media during operation. The other endplate includes a connection structure. A cover houses the filter element, and has an opening that is an inlet or outlet in fluid communication with the opening of the one endplate. The cover includes another fill opening proximate the other endplate. A cap is connected to the connection structure of the other endplate to close the opening of the cover. The cover is retained between the cap and other endplate. Generally, the attachment configuration between the cap and the other endplate of the filter element helps ensure that the filter element with the correct micron rating is installed in a filtration system.
Abstract:
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. A composite filter head is described that has integrally molded inlet and outlet fittings.

Abstract:
A fluid filter constructed and arranged for threaded engagement with a fluid-delivery head for the filtration of an incoming fluid includes a molded plastic shell having a sidewall formed with a retaining ridge, a closed end and an opened end surrounded by a series of external threads, a fluid filter media pack installed into the fluid filter shell, the media pack including filtering media and an upper endplate bonded to the upper end of the filtering media, wherein the upper endplate includes a peripheral lip that is constructed and arranged to snap into position axially beneath the retaining ridge. The threaded engagement between the fluid filter shell and the fluid-delivery head eliminates the need for any nutplate.
Abstract:
A disposable, spin-on fluid filter is constructed and arranged to mount onto a base that is configured with a threaded mounting shaft. The base provides a fluid inlet flow to the filter and a fluid exit path from the filter. The filter construction includes a housing canister having a closed end and an opposite, open end and a fluid filtering media positioned within the housing canister. A mounting post is formed as part of the closed first end of the housing canister. The mounting post is constructed and arranged for assembly to the threaded mounting shaft of the base. The design focuses on the elimination of any nutplate and on repositioning the location where the fluid filter is connected to the head to the closed end of the canister.
Abstract:
A fluid separation centrifuge for the separation of particulate matter from a flow of oil is designed with a disposable rotor assembly including a molded plastic rotor housing and a fluid separation device positioned within the rotor housing. Included as part of the fluid separation device is a unitary, molded plastic base plate which is designed and arranged with a peripheral lip formed with a channel portion therein. In a cooperating manner, the rotor housing is constructed and arranged with a molded plastic, generally cylindrical projection which is designed and arranged to receive the channel portion so as to create a fluid-tight, sealed interface at the location of contact between the projection and the channel portion.
