Abstract
An oil filtration apparatus includes external vanes with associated flow passages. Oil entering a housing passes through the flow passages with a heat exchange occurring between hot oil passing along the flow passages and cool air passing by the external vanes. Oil exiting an outlet end of the flow passages passes through a filter to reach an outlet of the housing. In a preferred embodiment, two alternative flow paths are provided. A first flow path provides only filtration. A second flow path provides both cooling and filtration. A valve is provided to allow a selection to be made between the first flow path and the second flow path.
Description
TITLE OF THE INVENTION:
oil filtration apparatus NAMES) OF INVENTOR(S):
Gerald Merchant FIELD OF THE INVENTION
The present invention relates to an oil filtration apparatus.
BACKGROUND OF THE INVENTION
All motor vehicles are equipped with some form of oil filtration apparatus. These oil filtration apparatus generally have a flow path with an inlet end an outlet end. A filter medium is disposed between the inlet end and the outlet end.
All oil that passes from the inlet end to the outlet end of the oil filtration apparatus must pass through the filter medium.
When oil is exposed to high temperatures it begins tc break down and loses its lubricating properties. It is, therefore, desirable in high performance applications to cool as well as filter the oil.
SUMMARY OF THE INVENTION
What is required is an oil filtration apparatus that is capable of cooling, as well as filtering, oil.
According to the present invention there is provided an oil filtration apparatus which includes a housing having a first end and a second end. A plurality of external vanes extend between the first end and the second end. The external vanes have associated flow passages having an inlet end at one of the first end and the second end of the housing and an outlet end at the other of the first end and the second end of the housing. An inlet flow passage for the entry of oil into the housing communicates with the inlet end of the flow passages in the external vanes. All oil entering the housing passes through the flow passages associated with the external vanes with a heat exchange occurring between hot oil passing along the flow passages and cool air passing by the external vanes. A filter retaining cavity is positioned in the flow path of oil exiting the outlet end of the flow passages. All oil exiting the outlet end of the flow passages must pass through a filter positioned within the filter retaining cavity.
An outlet flow passage communicates with the central filter retaining cavity, whereby oil exits the housing.
With the oil filtration apparatus, the oil is cooled by passing along the flow passages associated with the external vanes.
Although beneficial results may be obtained through the use of the oil filtration apparatus, as defined above, when the engine is cold or in cold weather conditions the cooling of the oil is no longer desirable. Even more beneficial results may, therefore, be obtained when the flow passages associated with the external vanes provide a second flow path and a first flow path is provided that communicates directly with the filter retaining cavity. Valve means are provided to enable a selection to be made between the first flow path and the second flow path.
With the provision of a valve, as described above, the oil filtration apparatus can be adapted to suit any operating conditions merely by selecting between the first flow path and the second flow path.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
The preferred embodiment, an oil filtration apparatus generally identified by reference numeral 10, will now be described with reference to FIGURES 1 through 7.
Referring to FIGURE 1, oil filtration apparatus 10 includes a housing 12 having an inlet 14, an outlet 16, and a central filter retaining cavity 18 in which is positioned a stainless steel mesh filter 20. Housing 12 has a first end 22 and a second end 24. Referring to FIGURE 2, a plurality of external vanes 26 extend between first end 22 and second end 24. Referring to FIGURE 3, each of external vanes 26 has an associated flow passage 28. Referring to FIGURE 7, each flow passage 28 has an inlet end 30 at second end 24 of housing 12 and an outlet end 32 at first end 22 of housing 12. Outlet end 32 of each of flow passages 28 communicates with central filter retaining cavity 18. Referring to FIGURE 1, inlet 14 is in communication with a rotatable valve cap 34 which allows a selection to be made between a first flow path, as is indicated by arrows 36 in FIGURE 6 and a second flow path, as is indicated by arrows 38 in FIGURE 7. Referring to FIGURE 5, in addition to flow passages 28, housing 12 has slots 40 that communicate with central filter retaining cavity 18. Referring to FIGURE 4, rotatable valve cap 34 has peripheral passages 42 and central passages 44. In a first rotational position, peripheral passages 42 are out of register with flow passages 28. When peripheral passages 42 are out of register with flow passages 28, central passages 44 are in register with slots 40.
This means that peripheral passages 42 are substantially blocked and substantially all oil flow entering valve cap 34 must pass through central passages 44 into central filter retaining cavity 18. Conversely, in a second rotational position, peripheral passages 42 are in register with flow passages 28. When peripheral passages 42 are in register with flow passages 28, central passages 44 are out of register with slots 40. This means that central passages 44 are substantially blocked and substantially all oil flow entering valve cap 34 must pass through peripheral passages 42 into flow passages 28. Referring to FIGURE 6, the first flow path permits oil entering valve cap 34 to pass through slots 40 and communicate directly with filter retaining cavity 18. Oil following the first flow path through slots 40 must pass through stainless steel mesh filter 20 positioned within filter retaining cavity 18 in order to reach outlet 16. Referring to FIGURE 7, the second flow path directs oil to inlet end 30 of flow passages 28 associated with external vanes 26.
Referring to FIGURE 3, oil following the second flow path passes through flow passages 28 with a heat exchange occurring between hot oil passing along flow passages 28 and cool air passing by external vanes 26. Referring to FIGURE 7, oil exiting outlet end 32 of flow passages 28 enters filter retaining cavity 18 and must pass through stainless steel mesh filter 20 in order to reach outlet 16.
It is important that the rotation of valve cap to make a selection of either the first flow path or the second flow path, make no difference in the pressure within oil filtration apparatus 10. Care must be taken in sizing the flow paths to make them substantially equal in terms of the flow rate they are capable of managing. In any oil filtration apparatus care must be taken to ensure that its capacity is suitable to the 5 engine, so that a back pressure is not created.
It will be apparent to one skilled in the art that modifications may be made to the illustrated embodiment without departing from the spirit and scope of the invention as hereinafter defined in the Claims.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
The preferred embodiment, an oil filtration apparatus generally identified by reference numeral 10, will now be described with reference to FIGURES 1 through 7.
Referring to FIGURE 1, oil filtration apparatus 10 includes a housing 12 having an inlet 14, an outlet 16, and a central filter retaining cavity 18 in which is positioned a stainless steel mesh filter 20. Housing 12 has a first end 22 and a second end 24. Referring to FIGURE 2, a plurality of external vanes 26 extend between first end 22 and second end 24. Referring to FIGURE 3, each of external vanes 26 has an associated flow passage 28. Referring to FIGURE 7, each flow passage 28 has an inlet end 30 at second end 24 of housing 12 and an outlet end 32 at first end 22 of housing 12. Outlet end 32 of each of flow passages 28 communicates with central filter retaining cavity 18. Referring to FIGURE 1, inlet 14 is in communication with a rotatable valve cap 34 which allows a selection to be made between a first flow path, as is indicated by arrows 36 in FIGURE 6 and a second flow path, as is indicated by arrows 38 in FIGURE 7. Referring to FIGURE 5, in addition to flow passages 28, housing 12 has slots 40 that communicate with central filter retaining cavity 18. Referring to FIGURE 4, rotatable valve cap 34 has peripheral passages 42 and central passages 44. In a first rotational position, peripheral passages 42 are out of register with flow passages 28. When peripheral passages 42 are out of register with flow passages 28, central passages 44 are in register with slots 40.
This means that peripheral passages 42 are substantially blocked and substantially all oil flow entering valve cap 34 must pass through central passages 44 into central filter retaining cavity 18. Conversely, in a second rotational position, peripheral passages 42 are in register with flow passages 28. When peripheral passages 42 are in register with flow passages 28, central passages 44 are out of register with slots 40. This means that central passages 44 are substantially blocked and substantially all oil flow entering valve cap 34 must pass through peripheral passages 42 into flow passages 28. Referring to FIGURE 6, the first flow path permits oil entering valve cap 34 to pass through slots 40 and communicate directly with filter retaining cavity 18. Oil following the first flow path through slots 40 must pass through stainless steel mesh filter 20 positioned within filter retaining cavity 18 in order to reach outlet 16. Referring to FIGURE 7, the second flow path directs oil to inlet end 30 of flow passages 28 associated with external vanes 26.
Referring to FIGURE 3, oil following the second flow path passes through flow passages 28 with a heat exchange occurring between hot oil passing along flow passages 28 and cool air passing by external vanes 26. Referring to FIGURE 7, oil exiting outlet end 32 of flow passages 28 enters filter retaining cavity 18 and must pass through stainless steel mesh filter 20 in order to reach outlet 16.
It is important that the rotation of valve cap to make a selection of either the first flow path or the second flow path, make no difference in the pressure within oil filtration apparatus 10. Care must be taken in sizing the flow paths to make them substantially equal in terms of the flow rate they are capable of managing. In any oil filtration apparatus care must be taken to ensure that its capacity is suitable to the 5 engine, so that a back pressure is not created.
It will be apparent to one skilled in the art that modifications may be made to the illustrated embodiment without departing from the spirit and scope of the invention as hereinafter defined in the Claims.
