Additive dispersing filter and method of making

1. A filter, comprising:

a housing defining an inlet fluid opening and an outlet fluid opening, the inlet fluid opening and the outlet fluid opening defining a fluid path through the filter;

a filter element disposed inside the filter housing, the filter element being disposed in the flow path such that fluid flowing through the flow path must pass through the filter element;

a dispersement device disposed within the housing, the dispersement device comprising a housing having a first chamber and a second chamber, the second chamber being sealed from the first chamber by a pair of dividing walls, the dispersement device being secured to the filter element and a central opening of the filter element and the dispersement device are in fluid communication with the outlet fluid opening;

a first additive disposed within the first chamber;

a second additive disposed within the second chamber;

a first metering opening that is sealed with an oil soluble material the first metering opening being in fluid communication with the first chamber when the oil soluble material is removed from the first metering opening; and

a second metering opening that is sealed with an oil soluble material the second metering opening being in fluid communication with the second chamber when the oil soluble material is removed from the second metering opening.

2. The filter as in claim 1 , wherein the first additive and the second additive are compositions comprising at least one additive selected from the group consisting of basic conditioners, corrosion inhibitors, metal deactivators, antioxidants, dispersants, friction modifiers, oil stabilizers, pour point depressants, detergents, viscosity index improvers, anti-wear agents, extreme pressure additives, and mixtures thereof.

3. The filter as in claim 2 , wherein the first additive and the second additive are compositions comprising a basic salt selected from the group consisting of lithium hydroxide, calcium carbonate, potassium carbonate, potassium bicarbonate, aluminum dihydroxy sodium carbonate, magnesium oxide, magnesium carbonate, zinc oxide, sodium bicarbonate, sodium hydroxide, calcium hydroxide, potassium hydroxide, and mixtures thereof.

4. The filter as in claim 1 , wherein the dispersement device is located substantially centrally in the filter housing between the inlet fluid opening and the outlet fluid opening and the filter element.

5. The filter as in claim 1 , wherein the dispersement device is formed from an oil tolerable plastic and the filter is an oil filter and the additive composition is a liquid.

6. The filter as in claim 5 , wherein the housing of the dispersement device further comprises a central opening aligned with the outlet fluid opening of the filter.

7. The filter as in claim 1 , wherein the dispersement device further comprises a cap secured to the housing of the dispersement device, the cap being secured to the housing of the dispersement device after the first additive is disposed in the first chamber and the second additive is disposed in the second chamber and the cap is positioned between the dispersement device and the filter element after the cap is secured to the housing of the dispersement device and the second chamber is larger than the first chamber and a larger amount of the second additive is disposed in the second chamber as opposed to an amount of the first additive disposed in the first chamber and the second chamber further comprises a pair of structural ribs, the structural ribs being configured so that they will not interfere with a fluid flow of the second additive from the second chamber.
