Abstract: A seal arrangement for a fluid filter assembly which is constructed and arranged to threadedly mount onto an engine block mounting base includes an inner seal and an outer seal. The fluid filter assembly includes an outer shell, a filtering element located within the outer shell and defining therewith an annular clearance space. The fluid filter assembly further includes a nutplate which is anchored to the outer shell and which includes an internally-threaded center aperture for threaded engagement onto the engine block mounting base. The inner seal is positioned between the nutplate and the filtering element and cooperates with the nutplate in order to provide a plurality of flow paths between the inner seal and the nutplate from the engine mounting base to the annular clearance space. The outer seal is positioned between the engine block mounting base and the nutplate and includes a pair of spaced-apart ribs which provide a sealing interface against the engine block mounting base.

Abstract: A combined full flow and bypass oil filter for internal combustion engines includes a generally cylindrical filter body and a generally cylindrical filter head which is threadedly attached to the filter body. The filter head includes an inlet and an outlet and the flow path between the inlet and outlet extends through the filter body. Disposed within the filter body is a generally cylindrical and hollow full flow filtering element and a generally cylindrical and hollow bypass filtering element. The incoming flow of lubricating oil passes through the outer diameter surfaces of the full flow and bypass filtering elements and exits from these filtering elements through their hollow interiors. Concentrically positioned in the exiting flow path of the full flow filter is a Venturi nozzle which creates a low pressure zone. An outlet flow conduit is disposed in flow cooperation with the exiting oil flow through the bypass filtering element and the exit opening of this flow conduit extending from the bypass filtering element is positioned within the low pressure zone of the Venturi nozzle. The pressure differential across the two filtering elements creates a forced flow through the bypass filtering element and the filtered oil through both elements combines as part of a single flow loop.

Abstract: A method and solid-state electronic flowmeter with no moving parts is provided for monitoring instantaneous and/or accumulated fluid flow. A preferred application for the method and flowmeter is the measurement of the total volume of filtered fluid in a fluid treatment system as an indication of end of life for a filter therein. The flowmeter employs a solid-state transducer which senses differential pressure generated by a flow restriction such as a venturi which varies depending on a rate of flow. The transducer output in integrated over time to provide a representation of total fluid flow through the filter. The meter is preferably compact and battery-powered to facilitate ease of installation and use. Battery power is conserved by periodically energizing the transducer during idle periods and by periodically energizing the end of life indicator during and end of life condition.

Abstract: A method of operating a filter centrifuge or centrifugal filter in which a hydrostatic head is provided at the filtering surface so as to control liquid passage therethrough. The head may promote movement of the liquid through the filter layer or may induce reverse flow of liquid for backwashing or rinsing. In addition, a hydrostatic balance may be provided at this surface through control of the head to limit passage of the liquid through the filter layer. Preferably the head provides a suction augmenting centrifugal filtration.

Abstract: A separator for removing particulate contamination from a flowing medium of a different density. The separator incorporates means such as a venturi for directing and accelerating the particulate into a predetermined location in the flow and a screen assembly located downstream of the director. The screen assembly extends across the location in the flow where particles are directed to enable the primary flow path of the medium to bypass the screens if need be. The screen assembly can be comprised of one or more stages which separate and entrap particles. The screen assembly may be spring mounted to accommodate variable velocity flow and may include means for regenerating the screens.
