Attorney, Agent or Firm:
An oil-conditioning filter, for use with an internal combustion engine, includes a mechanical filter element and a central additive cartridge, for gradually dispensing an oil additive over time. The additive cartridge has a beneficial oil-conditioning agent contained therein. The additive may be provided as a solid block within a storage chamber of the cartridge, or may be a plurality of pellets. Central placement of the cartridge allows for fluid filtration through the mechanical filter element before the additive is added thereto, reducing the likelihood that the additive will be filtered out prematurely upon its initial release. An additive cartridge for installation in an oil filter is also described, including a baffle portion and a storage chamber. Alternative exemplary embodiments of the additive cartridge may include a cylindrical shell, a basket which is operatively attached to an oil filter center tube, or a porous center tube. |

DETAILED DESCRIPTION The present invention provides an improved oil filter, having a basic conditioner and/or another beneficial additive incorporated therein.
In the practice of the present invention, the beneficial additive is housed within a centrally located additive dispenser cartridge, which is operable to dispense an additive composition into relatively clean filtered oil that has already passed through a mechanical filter element.
In a particular embodiment of the invention, the additive chamber includes an additive cartridge which is a hollow shell, and a beneficial additive contained within the housing.
The additive chamber is located inside of the mechanical filter element at a central part of the filter, so that the oil has already been mechanically filtered when additive is added thereto.
The apparatus according to the invention may also include a baffle for directing oil flow, and the additive cartridge may be attached to the baffle.
Where the baffle is used, a dividing wall may be provided between the baffle and the additive chamber.
The additive cartridge has at least one opening, and may have a limited number of openings therein to control the rate of diffusion therefrom.
Accordingly, it is an object of the present invention to provide an improved oil filter including one or more beneficial oil additives that are released slowly over the life of the filter.
For a more complete understanding of the present invention, the reader is referred to the following detailed description section, which should be read in conjunction with the accompanying drawings.
Throughout the following detailed description and in the drawings, like numbers refer to like parts.
