Oil filter cleaner including arrangement for cleansing of cleaner solvent

Claim 2

The filter cleaner of claim 1 wherein a segment of the tube means extending into the upper area of the container is formed as a diffuser, said oil filter seating upon this diffuser segment of the tube means thereby directing the solvent and compressed gas to enter into and pervade throughout the oil filter during the flushing operation, and the means supporting said oil filter confining the flow of solvent substantially through said filter while preventing its discharge from the filter ends.

Claim 3

A filter cleaner for use in flushing by means of a solvent an oil filter of the type normally used in conjunction with an internal combustion engine comprising a container, said container having a substantially closed compartment formed integrally in its lower portion and arranged for normally retaining the solvent used in cleaning the oil filter, the upward portion of the container providing an area for retention of the oil filter during the flushing process, there being an area formed intermediate the upper and lower portions of the container for providing temporary disposition of the solvent after it passes through the oil filter, tube means supported in said container and extending from proximate the lower regions of the closed compartment at its downward end and projecting upwardly and opening into the upper area of the container at its other end, means rigidly supporting an oil filter associated with the end of the tube means projecting into said upper area of the container, said tube means projecting into the upper area of the container being formed as a diffuser, said oil filter seating upon this diffuser segment of the tube means thereby directing the solvent and compressed gas to enter into and pervade throughout the oil filter during the flushing operation, the diffuser segment of the tube means being externally threaded, base means provided proximate the lower end of the diffuser for holding said oil filter upon the diffuser, a plate threadedly engaging with the diffuser for use in tightening against the upper end of said oil filter thereby furnishing its rigid support during the flushing operation, means admitting gas under pressure into the closed compartment thereby forcing said solvent and a gas through the tube means and into and through said diffuser and supported oil filter, means allowing discharge of the compressed gas from the upper area of the container, a supplemental filter arrangement between said upper and intermediate areas of the container for filtering the cleaning solvent discharged from the oil filter and before its temporary depositing within said intermediate area, and a valve communicating between said intermediate area and the closed compartment for providing drainage of the filtered solvent back into said closed compartment.

Claim 4

The filter cleaner of claim 4 wherein the plate is provided with means for grasping and facilitating its rapid turning during its threaded engagement with the diffuser.

Claim 5

The filter cleaner of claim 4 and further characterized by a sleeve integrally connectiNg with the plate and projecting axially upward from its surface thereof, said sleeve being threadedly engaged with that portion of the diffuser inserting within the sleeve thereby preventing discharge of the solvent from this contiguous portion of the diffuser.

Claim 6

A filter cleaner for use in flushing by means of a solvent an integral type oil filter of the kind normally used for end mounting with an internal combustion engine comprising a container, said container having a substantially closed compartment formed integrally in its lower portion and arranged for normally retaining the solvent used in cleaning the oil filter, the upper portion of the container providing an area for retention of the oil filter during the flushing process, there being an area formed intermediate the upper and lower portions of the container for providing temporary disposition of the solvent after it passes through the oil filter, said upper, intermediate and lower portions being integrally formed of the container and being vertically arranged upon each other, tube means supported in said container and extending from proximate the lower regions of the closed compartment at its downward end and opening into the upper area of the container at its other end, means rigidly supporting an oil filter associated with the end of the tube means opening into the upper area of the container, said means comprising an adapter that threadedly engages with said end of the tube means, said adapter being disposed for threadedly engaging with an end of the oil filter, means admitting gas under pressure into the closed compartment thereby forcing said solvent and the gas through the tube means and adapter and into and through the supported filter, the seating of said oil filter upon said tube means and adapter providing for the directing of the solvent and compressed gas to enter into and pervade throughout the oil filter during the flushing operation thereby confining the flow of solvent substantially through said filter, means allowing discharge of the compressed gas from the upper area of the container, a supplemental filter arranged between said upper and intermediate areas of the container for filtering the cleaning solvent discharged from the oil filter and before its temporary depositing within said intermediate area, and a valve communicating between said intermediate area and the closed compartment for providing drainage of the filtered solvent back into said closed compartment.

Claim 7

The filter cleaner of claim 7 wherein the filter arranged between the upward and intermediate areas of the container is formed of fibrous material and is disposable after each cleaning of an oil filter.
