Magnetic filter for lubricants

Claim 2

A magnetic assembly for attracting particles floating in a fluid, comprising a non-magnetic elongated support member, a plurality of centrally apertured magnets through which the support member extends with the poles in alignment, each magnet being provided with an individual pole piece at each pole thereof with adjacent pole pieces in non-contacting relation, said pole pieces each comprising a centrally apertured planar disc having a plurality of radially extending vanes about its periphery, the vanes being formed with their side edges out of the plane of the disc hub but extending radially thereof.

Claim 3

A magnetic assembly according to claim 1 wherein the elongated support member is resilient.

Claim 4

A magnetic assembly according to claim 2 wherein the elongated support member is a rod of plastic material.

Claim 5

A magnetic assembly according to claim 2 wherein the elongated support member is a coiled wire spring.

Claim 6

A magnetic assembly according to claim 1 wherein the vanes are twisted about the radius of the disc along which they extend.

Claim 7

A magnetic assembly according to claim 5 wherein the pole pieces of adjacent magnets are separated by non-magnetic spacers.

Claim 8

A magnetic assembly according to claim 1 wherein the vanes are fluted.

Claim 9

A magnetic assembly according to claim 5 wherein the pole pieces of adjacent magnets are separated by non-magnetic spacers.

Claim 10

A magnetic assembly according to claim 1 wherein the elongated support member is resilient and the magnets, pole pieces and spacers are stacked on the support member, and means for securing them in stacked relation.

Claim 11

A magnetic assembly according to claim 9 wherein like poles of adjacent magnets are adjacent each other.

Claim 12

An oil pan for an internal combustion engine comprising a shallow chamber and a deep chamber contiguous thereto, magnetic means supported adjacent the line of contiguity between said chambers, means for guiding flow of fluid from the shallow chamber onto the magnetic means, and additional magnetic means secured in the bottom of the deep chamber, the bottom of the shallow chamber being sloped toward the deep chamber, the bottom of the deep chamber being sloped toward the shallow chamber, the means for guiding the flow of fluid comprising a plate secured to the bottom of the shallow chamber with a free edge of said plate extending over said first mentioned magnetic means, the bottom of the deep chamber being formed with a channel and the second mentioned magnetic means being mounted in the channel and a plate mounted over the deep chamber with a free edge thereof extending over said first mentioned plate.

Claim 13

An oil pan for an internal combustion engine comprising a shallow chamber and a deep chamber contiguous thereto, magnetic means supported adjacent the line of contiguity between said chambers, means for guiding flow of fluid from the shallow chamber onto the magnetic means, and additional magnetic means secured in the bottom of the deep chamber, the bottom of the shallow chamber being sloped toward the deep chamber, the bottom of the deep chamber being sloped toward the shallow chamber, the means for guiding the flow of fluid comprising a plate secured to the bottom of the shallow chamber with a free edge of said plate extending over said first mentioned magnetic means, the bottom of the deep chamber being formed with a channel and the second mentioned magnetic means being mounted in the channel and a plate mounted over the deep chamber with a free edge thereof extending over said first mentioned plate.

Claim 14

A device as defined in claim 11 wherein each magnetic means comprises a rod, a plurality of permanent magnets mounted on the rod with like poles facing each other, and a pair of pole pieces separated by a non-magnetic spacer mounted on the rod between each of the magnets.

Claim 15

An oil pan according to claim 12 wherein the pole pieces each comprise a planar disc having a plurality of vanes angularly spaced about its periphery extending substantially radially, at least a portion of the edges of each of the vanes of the pole pieces of a magnet are twisted to face toward the opposite pole piece.

Claim 16

An oil pan according to claim 13 wherein the vanes are bent to position their surfaces in a plane at an angle to the plane of the disc from which they extend.
