INVENTION PROFILE
Introduction. We’d like to
submit to interested companies
the patented invention – combined
oil filter element (hereafter - "COFE"), which combines
full-flow and bypass filter element sections in standard spin-on filter. COFE
is significantly superior to all known oil filter elements on the critical
technical and operational parameters. Reality and effectiveness of the
invention has been confirmed experimentally. The invention is well prepared for
industrial manufacturing. Combination of technological, technical, operational
and price advantages of COFE allow to COFE manufacturer to capture leading
position in the oil filter market. We suggest interested companies to consider
our proposal to purchase our rights on the invention.
Brief description of the invention. COFE is the
construction consisting of tightly interconnected full-flow and bypass filter
element sections. In various COFE options paper filtering media is replaced for
textured thread, or non-woven synthetic material. COFE is housed in standard
spin-on filter. Technical solutions, realized in the invention, allow improving
significantly critical technical and operational parameters of automotive oil
filters, compared with the existing analogues. At the technological level the
COFE design is characterized by various technical parameters of filter media,
which allows with no additional cost significantly enhance the effectiveness of
filtering system. COFE application provides for high-quality conditioning motor
oil, increases the period of its operation, and provides therefore for high level of engine
protection. In
COFE manufacturing can be applied just existing technological processes. COFE
can be used as in spin-on oil filters and in the other version where only COFE needs to be replaced
in the housing. Filter design and its price parameters allow its use in all types of vehicles.
Summary of patent
N 2289467 "Combined filter element of oil filter". Combined filter
element of oil filter consists of two interconnected filter element sections
with different types of filtering media, is housed in filter body with one
outlet for filtered oil, can be equipped with bypass valve, depending on the
filter design. First filter element section is the full-flow filter element section and consists of central perforated
pipe, upper and lower lids, between which paper media is installed. Second filter element section is the
bypass filter element section and consists of central tube with grooves on its
outer side or of central perforated pipe with wound on it at variable force of
synthetic textured thread forming the space-capillary filtering media. The
technical result of the invention is the increased fineness of screening and
filter contaminant capacity, duration of the oil operation life and filters
itself, reduction of abrasive wear of rubbing details, increased operational
life of combustion engines.
Summary of patent
N 2306968 "Combined filter element". Combined filter
element consists of two filter elements, one above the other with a filter
media characterized by different technical specifications. In the place of coupling of covers of filter elements
there is a pipe or partition dividing stream of purified oil. Second filter
element contains synthetic space-capillary filtering media, which has been made
of textured thread by means of its winding at variable-force and has the lower
productivity and the higher degree of filtration and the much higher pollution
capacity than filtering media of first filter element. Technical result of the
invention is the increased quality of filtration and increased service life of
combined filter element, its efficiency and cost reduction.
Combined oil filter element structure and its principles
of working. The
oil filter contains shell 1, spring twisted installation 2, bypass valve saddle
3, bypass valve 4, the upper lid of first filter element 5, bypass valve spring
6, bypass valve body 7, paper filtering media (or space-capillary
filtering media made of
textured thread, or filtering media made of
non-woven synthetic material) of first filter element 8, pipe with longitudinal
channels of first filter element 9, the lower lid of first filter element 10,
pipe, separating the oil flow 11, the upper lid of second filter element 12, filtering media
made of non-woven synthetic material (or space-capillary filtering media made of textured thread) of second filter
element 13, pipe with longitudinal channels of second filter element 14, the
lower lid of second filter element 15, twisted spring 16, spring of anti-drain
valve 17, shell cover 18, amplifying plate 19, rubber gasket 20, anti-drain
valve 21.
The combined oil
filter element of spin-on oil filter (fig.1) works as follows. Oil from engine
pump through the shell cover 18 having a
sealing rubber gasket 20 for sealing compound of shell cover with engine block,
overcomes anti-drain valve 21, enters
the filter between the inner wall of the shell 1 and the outer surface of the
combined filter element. With cold start (at the time of launch) oil, having
high viscosity, passes partially through first filtering media 8 and partially
through bypass-valve 4 and enters into the main engine oil flow. In this case,
filtering media 13 of second filter element doesn’t participate in filtration,
because its high density prevents this. In the process of engine work oil is
heated, its viscosity decreases so that the bypass valve 4 closes, most of the
oil passes through filtering media 8, the rest of the oil passes through
filtering media 13, which provides compared with filtering media 8 increased fineness of
screening, increased filter contaminant capacity, reduction of the abrasive
wear of the rubbing details, which precludes their getting into the system, and
reduces the burden on filtering media 8. For most efficient use of filtering
media 13 in the construction of the combined filter element there is pipe,
separating the flow of filtered oil 11, which forms in the inner cavity of combined
filter element two zones A and B. It is anticipated that in zone B the oil
pressure will be slightly lower than in zone A, which contributes to increased
productivity of filtering media 13 (in this case through filtering media 13
passes up to 10% of oil) and to effectiveness of filtering system as a whole.
Reality and
effectiveness of the invention. In order to verify the COFE
effectiveness were manufactured semi industrial COFE samples. Full-flow and
bypass COFE sections were made at Russian enterprises that produce these
components on an industrial scale. The COFE effectiveness was confirmed
experimentally in the Russian Automotive Test Center (a copy of the test report
is presented in Appendix). In particular, comparative tests of standard
full-flow filter element and three COFE samples showed that their use increases
the time to filter pollution in the 1.2 - 1.6 times, the waste concentration in
oil for the duration of the filter decreases in the 1.5 -3.0 times. At
technological level the COFE design makes possible to change technical
characteristics of filtering media, which allows without significant cost
significantly improve effectiveness of filtering, even in comparison with these
tests which were recorded.
Condition and market analysis of automotive oil
filters allows note:
1.
the annual volume
of Russian market of oil filters and filter elements is not less than 34
million pieces,
2.
international and
Russian oil filters market is moving towards manufacturing oil filters, which
could provide a higher level of filtering for all kinds of vehicles,
3.
the problem of
ensuring a higher level of filtering can be resolved only by combined oil
filters, coupled with a new filter materials,
4.
currently produced
combined oil filters have a high cost, which is a major obstacle to their wide
trading,
5.
lowering the total
cost of combined oil filters can be solved only through optimization and
cheaper construction and materials used in combined oil filters,
6.
COFE is able to
solve problems facing the oil filter market already now.
Readiness of the
invention for industrial application. All COFE
components are well-developed technologically and are manufactured in many
countries, including Russia, on industrial scale. COFE dimensions are adapted
to the sizes of standard spin-on oil filters. In COFE manufacturing can be
applied just existing manufacturing processes and therefore no significant
costs on the technological upgrading of production is not provided. Available
design documentation and testing results permit to hold COFE certification in
the shortest possible time and begin manufacturing and trading COFE in Russia
and other countries.
The economic
rationale and prospects for COFE manufacturing. Assuming that:
•
on the market a
wide range of oil filters and oil filter elements are presented,
•
all COFE
components are manufactured in Russia and in other countries on industrial
scale,
•
the COFE
manufacture cost will be more expensive than standard full-flow oil filters and
filter elements respectively by about 20 cents due to include in the COFE
construction of synthetic filter media section and partitions separating
full-flow and bypass sections,
•
COFE improves
significantly the quality of filtering oil, leading to an increase in lifespan of
the oil and oil filter, reduces abrasive rubbing parts and increases the
resource of engine working,
•
COFE has
understandable to all end-users significant advantages over all other oil
filters,
•
the invention has
been patented, and that’s why none in Russia, except for a company bought the
right to use the invention, would have no legal right to manufacture and trade
COFE or its analogs,
COFE
industrial application will allow to the COFE manufacturer:
1.
to capture not
less than 30% of the Russian and CIS (former Soviet republics) oil filter
market;
2.
to manufacture and
trade COFE in other countries except Russia without license;
3.
to provide annual
sales of COFE only in Russia not less than 12 million pieces;
4.
to increase the
price of one COFE (or oil filter using COFE) compared with analogues of not
less than 1 $;
5.
to obtain
additional pre-tax profit of not less than USD 0.80 from one COFE (or
oil filter using COFE);
6.
to get additional
annual pre-tax profit from COFE sales only in Russia not less than USD 9.6
million (other countries are not taken into account).
