Benefits of technology

[0010] The arm pieces can be configured to reversibly mount the filter apparatus to the inside of a conventional oil filter, a filter cartridge element, a fluid reservoir, a transmission fluid flow line, or a hydraulic fluid flow line. The arm pieces may comprise a disc shaped center and a plurality of arms extending substantially radially from the disc shaped center.
[0011] A fluid filter apparatus comprises a magnetic array, comprised of a plurality of magnets arranged in a like-pole t

Problems solved by technology

Foreign particles are often shed by the mechanical system in operation into the lubricating fluid where it can cause wear and damage to the operating system and its components.
However, prior magnetic filters were typically limited in that their design was specific for a particular application environment.
For example, the majority of current magnetic filters are limited to their application to engine oil filtration systems within automobiles.

Embodiment Construction

[0029] Embodiments of the invention relate to a magnetic fluid filter for filtering metallic particles from a fluid flow system. One example of such a fluid flow system is a power steering unit in an automobile. This embodiment includes a cylindrical outer casing mated to two end pieces for incorporating the filter into a fluid flow line.

[0030] Inside the magnetic fluid filter is an array of magnets that is held in place by a support. In one embodiment, the magnetic array has a plurality of disc shaped magnets separated by “pole pieces”. The magnets, each having a north pole and south pole, are arranged in a like-pole to like-pole configuration (north to north and south to south), and separated by the pole pieces. This configuration of magnetic like-poles creates a large magnetic gradient that attracts metallic particles to the surface of the array.

[0031] As can be imagined, embodiments of the invention are not limited to the specific magnetic array described above. For example, t...

Abstract

A magnetic fluid filter for filtering metallic particles from a fluid flow system. The filter comprises a magnetic array, a central support for the magnetic array, and arm pieces for positioning the effective range of the magnetic array in a fluid flow environment. The magnetic array includes a plurality of disc shaped magnets arranged with poles in opposition, interleaved with the arm pieces and disc shaped pole pieces.

Description

CROSS REFERENCE TO RELATED APPLICATION [0001] This application is a continuation of U.S. patent application Ser. No. 10 / 277,529 entitled “MAGNETIC FLUID FILTER” filed on Oct. 21, 2002, which is a continuation-in-part of U.S. patent application Ser. No. 10 / 032,276 entitled “MAGNETIC FLUID FILTER” filed on Dec. 21, 2001. The disclosure of the above-described filed applications are hereby incorporated by reference in its entirety.BACKGROUND OF THE INVENTION [0002] 1. Field of the Invention [0003] The present invention relates to a filter, and more particularly a magnetic filter for removing solid particles from a fluid. [0004] 2. Description of the Related Art [0005] It is common practice to use fluids to lubricate moving parts of mechanical systems. Foreign particles are often shed by the mechanical system in operation into the lubricating fluid where it can cause wear and damage to the operating system and its components. Many mechanical systems already make use of primary filters to...
