1. Field of the Invention
The present invention relates generally to oil filters for vehicles, and, more particularly, to oil filters that have magnetic enhancement of oil filtration.
2. Description of the Prior Art
The magnetic enhancement of oil filtration with oil filters installed on vehicles is well known in the art. In particular, U.S. Pat. No. 6,649,053 and U.S. Pat. No. 6,75.8,969, both by present inventor, Joseph C. Caiozza, disclose magnetic enhancement of oil filtration.
More specifically, U.S. Pat. No. 6,649,053 discloses an oil filter that has magnet units attached thereto. Each magnet unit has a magnet unit lock pin reception channel. A pair of magnet unit support members are attached to the bottom of a conventional oil filter. Each magnet unit support member has a support member lock pin reception channel. To attach the magnet units to the oil filter, the magnet unit lock pin reception channels and the support member lock pin reception channels are placed in registration, and a lock pin is inserted through the registered lock pin reception channels. Because there are only two magnet unit support members, and because each magnet unit support member has only one reception channel, forces keeping magnet units attached to the oil filter are spread over only two support member reception channels. This concentration of supporting forces on only two reception support member reception channels can prematurely wear those reception channels and accelerate failure. In this respect, it would be desirable if a magnet unit assembly were attached to an oil filter with a more stable arrangement than a pair of support member lock pin reception channels.
U.S. Pat. No. 6,758,969 discloses a magnetically enhanced oil filter apparatus in which a magnet assembly is kept in place on an outside housing by using a retention rod which is threaded through retention plates and retention-rod-reception brackets for fixing a disk-shaped magnet and a flux concentrator plate on the cartridge housing. A cotter pin is used to secure the retention rod to the retention plates and the retention-rod-reception brackets. It is noted that only two opposite locations around the cartridge housing are used for securing the retention rod, the retention plates, and the retention-rod-reception brackets on the cartridge housing. Rather than having only two opposite locations around the cartridge housing for securing the various components onto the cartridge housing, it would be desirable if substantially the entire periphery of the cartridge housing were employed for securing components related to the magnetically enhanced oil filter apparatus thereto.
With both U.S. Pat. Nos. 6,649,053 and 6,758,969, cotter pins, or the like, must be threaded through complementary reception channels in retention rods to secure a magnetically enhanced oil filter apparatus onto a cartridge housing. Because a reception channel may be quite small, and because it may difficult to see such a reception channel when a cartridge housing is installed on an engine block, it would desirable if means were provided for securing components of a magnetically enhanced oil filter apparatus onto a cartridge housing without the need to employ a cotter pin and a cotter pin reception channel in a retention rod.
When a magnetically enhanced oil filter apparatus is employed, at times it may be desirable to remove metal particles that are inside an oil filter portion and that are pulled toward a magnet assembly. To remove such particles, it would be desirable to separate the magnet assembly from the oil filter portion and to separate the portion of the oil filter that retains the metal particles from the cartridge housing. As just described, functionally one would expect there to be two separate and distinct connection means involved. A first connecting means for connecting the magnet assembly to the oil filter portion and a second, separate and distinct, connecting means for connecting the oil filter portion to the cartridge housing. For purposes of simplicity and economy of materials and labor involved, it would be desirable if the two separate and distinct connecting means could be combined into single connecting means that perform the two functions of connecting the magnet assembly to the oil filter portion and of connecting the oil filter portion to the cartridge housing.
Thus, while the foregoing body of prior art indicates it to be well known to use a magnetically enhanced oil filter apparatus, the prior art described above does not teach or suggest a magnetically enhanced oil filter apparatus which has the following combination of desirable features: (1) provides a magnet unit assembly that is attached to an oil filter with a more stable arrangement than a pair of support member lock pin reception channels; (2) employs substantially the entire periphery of a cartridge housing for securing components related to the magnetically enhanced oil filter apparatus thereto; (3) provides means for securing components of a magnetically enhanced oil filter apparatus onto a cartridge housing without the need to employ a cotter pin and a cotter pin reception channel in a retention rod; and (4) provides single connecting means that perform the two functions of connecting the magnet assembly to the oil filter portion and of connecting the oil filter portion to the cartridge housing. The foregoing desired characteristics are provided by the unique magnetically enhanced oil filter apparatus of the present invention as will be made apparent from the following description thereof. Other advantages of the present invention over the prior art also will be rendered evident.

With reference to the drawings, a new and improved magnetically enhanced oil filter apparatus embodying the principles and concepts of the present invention will be described.
Turning to
In the preferred embodiment, magnetically enhanced oil filter apparatus 10 includes an open-ended cartridge housing 12 which includes means for connecting to an engine block, inflow ports 16 for receiving oil flow from the engine block 11, and an outflow port 18 for sending filtered oil to the engine block 11. A block-to-housing sealing gasket 14 is connected to the open-ended cartridge housing 12 for providing a seal between the open-ended cartridge housing 12 and the engine block 11. Direction control baffles 22 are housed inside the open-ended cartridge housing 12 for directing inflow oil for magnetic treatment and for directing magnetically-treated oil to the outflow port 18. A cartridge-housing lid 50, a lid-to-housing sealing gasket 30, and a magnet assembly unit 52 are provided. A peripheral clamping assembly 24 is provided for clamping the magnet assembly unit 52, the lid-to-housing sealing gasket 30, and the cartridge-housing lid 50 to the open-ended cartridge housing 12. The cartridge-housing lid 50 is made from ferromagnetic material.
Preferably, the peripheral clamping assembly 24 includes a cartridge-housing engagement portion 58, a lid-to-housing-sealing-gasket engagement portion 60, and a magnet-assembly-unit engagement portion 62.
Preferably, the magnet assembly unit 52 includes a clamp-member-reception notch 64.
Preferably, the means for connecting to an engine block include an internally threaded portion 20 for connecting to an externally threaded engine portion.
Preferably, filtration means are housed within the open-ended cartridge housing 12.
Preferably, the open-ended cartridge housing 12 includes a housing end lip 26. Also, the cartridge-housing lid 50 includes a lid lip 28, and the lid-to-housing sealing gasket 30 is placed between the lid lip 28 and the housing end lip 26, whereby the peripheral clamping assembly 24 clamps the lid-to-housing sealing gasket 30 between the housing end lip 26 and the lid lip 28. Thereby, a liquid seal is formed between the open-ended cartridge housing 12 and the cartridge-housing lid 50.
Preferably, the peripheral clamping assembly 24 includes a pair of concave clamping members 32. Each clamping member 32 includes a cartridge-housing engagement portion 58, a lid-to-housing-sealing-gasket engagement portion 60, and a magnet-assembly-unit engagement portion 62. A hinge 34 connects the clamping members 32 together, and an over-center-toggle lock unit 36 is connected to the clamping members 32.
The over-center-toggle lock unit 36 includes a handle member 40 is connected to one of the clamping members 32. A hook-to-handle ring 42 is connected to the handle member 40, and a hook 38 located at an end portion of the other of the clamping members 32.
The over-center-toggle lock unit 36 further includes a cotter pin 54 and respective registrable cotter-pin-reception channels 56 in the handle member 40 and one of the clamping members 32.
Preferably, the lid-to-housing sealing gasket 30 includes a housing-end-lip contact portion 44, a unit-lip contact portion 46, and a clamping-member contact portion 48.
To use a fully assembled magnetically enhanced oil filter apparatus 10 of the invention, the internally threaded portion 20 of the open-ended cartridge housing 12 is screwed onto the oil filter fitting 13 of the engine block 11. When the engine is operating, oil flows into the open-ended cartridge housing 12 through the inflow ports 16. Inside the open-ended cartridge housing 12, the direction control baffles 22 direct oil through the filtration means (not shown) and direct oil to flow next to the cartridge-housing lid 50. Magnetic flux lines (not shown) permeate through the cartridge-housing lid 50 into the open-ended cartridge housing 12 from the magnet assembly unit 52 which is positioned next to the cartridge-housing lid 50 outside the open-ended cartridge housing 12. As a result, ferromagnetic particles in the oil are trapped onto the inside surface of the cartridge-housing lid 50 by the magnetic flux. Then, magnetically treated oil flows out from the open-ended cartridge housing 12 and back into the engine block 11 through the outflow port 18.
To clean the magnetically enhanced oil filter apparatus 10, the apparatus 10 is unscrewed from the oil filter fitting 13 and residual oil inside the apparatus 10 is drained. Then, the cotter pin 54 is removed from the over-center-toggle lock unit 36, and the handle member 40 is lifted so that the hook-to-handle ring 42 disengages from the hook 38. Then, the two clamping members 32 are pulled away from each other and around the hinge 34. Then, the peripheral clamping assembly 24 is removed from the apparatus 10.
When the peripheral clamping assembly 24 is removed from the open-ended cartridge housing 12, the cartridge-housing lid 50, the lid-to-housing sealing gasket 30, and the magnet assembly unit 52 separate from the open-ended cartridge housing 12 and each other.
Then, maintenance steps can be taken. More specifically, any ferromagnetic particles residing on the inside surface of the cartridge-housing lid 50 can be cleaned off thereof. Also, the magnet assembly unit 52 can be modified or replaced. Also, any filtration means can be replaced.
After the maintenance steps have been taken, the apparatus 10 is reassembled. More specifically, the cartridge-housing engagement portions 58 of the clamping members 32 engage the housing end lip 26. The lid-to-housing-sealing-gasket engagement portions 60 of the clamping members 32 contact the clamping-member contact portion 48 of the lid-to-housing sealing gasket 30, the unit-lip contact portion 46 of the lid-to-housing sealing gasket 30 is placed on the inside of the lid lip 28, the rear side of the lid-to-housing sealing gasket 30 contacts a vertically descending wall 66 of the cartridge-housing lid 50, and the magnet-assembly-unit engagement portions 62 of the clamping members 32 engage a complementary clamp-member-reception notch 64 in the magnet assembly unit 52.
Then, the reassembled magnetically enhanced oil filter apparatus 10 can be screwed back onto the oil filter fitting 13 of the engine block 11.
The magnet assembly unit 52 can take many alternative forms. For example, the magnet assembly unit 52 can be derived from the respective magnet assemblies shown and described in the above-mentioned U.S. Pat. No. 6,649,053 and U.S. Pat. No. 6,758,969, both incorporated herein by reference.

A second semi-circular magnet holder 80 has a second straight wall 82, a second curved wall 84, and a second top wall 86. In addition, the first straight wall 72 includes a first magnet end reception well 73, and the second straight wall 82 includes a second magnet end reception well 83. The first semi-circular magnet holder 70 and the second semi-circular magnet holder 80 are made from ferromagnetic material.

A plurality of second magnets 88 are received in the second semi-circular magnet holder 80 and have a second magnetic polarity orientation which is opposite to the first magnetic polarity orientation.
A plurality of third magnets 90 are located between the first semi-circular magnet holder 70 and the second semi-circular magnet holder 80. The third magnets 90 are nested within the first magnet end reception well 73 and the second magnet end reception well 83. The third magnets 90 have a third magnetic polarity orientation which is perpendicular to both the first and the second magnetic polarity orientations.
The bottom wall unit 92 is connected to the first semi-circular magnet holder 70 and the second semi-circular magnet holder 80. The bottom wall unit 92 is made from ferromagnetic material.
Preferably, the first magnets 78 and the second magnets 88 have a magnet length 91, the first semi-circular magnet holder 70 and the second semi-circular magnet holder 80 have a magnet holder height 93. The magnet length 91 is greater than the magnet holder height 93, whereby, when the bottom wall unit 92 is connected to the first and second semi-circular magnet holders, a clamp-member-reception notch 64 is provided between the first and second semi-circular magnet holders and the bottom wall unit 92. The bottom wall unit 92 can include cooling fins 96.
More specifically, connecting screws 94 are used to fasten the bottom wall unit 92 to the first straight wall 72 of the first semi-circular magnet holder 70 and to the second straight wall 82 of the second semi-circular magnet holder 80. Even more specifically, a first screw-reception well 71 is located in the first straight wall 72 and receives one of the screws 94, and a second screw-reception well 81 is located in the second straight wall 82 and receives the other of the screws 94.
When the bottom wall unit 92 is connected to the first and second semi-circular magnet holders, the clamp-member-reception notch 64 receives the magnet-assembly-unit engagement portions 62 of the clamping members 32. In this way, the clamping members 32 secure the magnet assembly unit 52 to the open-ended cartridge housing 12.
The magnetically enhanced oil filter apparatus 10 can be referred to as “The Black Hole” magnet system.
The components of the magnetically enhanced oil filter apparatus of the invention can be made from inexpensive and durable metal and plastic materials.
As to the manner of usage and operation of the instant invention, the same is apparent from the above disclosure, and accordingly, no further discussion relative to the manner of usage and operation need be provided.
It is apparent from the above that the present invention accomplishes all of the objects set forth by providing a new and improved magnetically enhanced oil filter apparatus that is low in cost, relatively simple in design and operation, and which may advantageously be used to provide a magnet unit assembly that is attached to an oil filter with a more stable arrangement than a pair of support member lock pin reception channels.
