Abstract: An additive dispensing device is provided. The additive dispensing device includes a reservoir configured to contain a supply of an additive. The reservoir is in fluid communication with a dispensing chamber of a metering valve device by a first one-way valve. The metering valve device is configured to dispense a portion of the additive from the dispensing chamber into a housing by a second one-way valve. The additive dispensing device further includes a thermal expanding member disposed in the dispensing chamber. The thermal expanding member is configured to expand and contract between expanded and contracted positions, respectively, in response to temperature. The thermal expanding member decreases a pressure in the dispensing chamber as the thermal expanding member moves toward the contracted position, such that additive is drawn from the reservoir into the dispensing chamber through the first one-way valve.

Abstract: An oil filtration assembly for filtering oil comprises a housing having an inlet port and an outlet port defining a flow path for oil to flow therethrough. A diatomaceous earth filtering media layer is disposed in the oil flow path, intermediate of the inlet port and the outlet port and is configured to filter soot and contaminants from oil passing through the oil filtration assembly.

Abstract: A fluid containment apparatus for use with a fluid filter removably disposed on a substrate is provided. The apparatus comprises a flexible band having a fluid absorbent layer and a fluid barrier layer. The absorbent layer has a first edge, a second edge, an interior side, and an exterior side. The interior side of the absorbent layer is configured to be disposed proximately about an outer surface of the fluid filter to absorb fluid spillage therefrom. The first edge of the absorbent layer is configured to be disposed adjacent to the substrate to absorb fluid spillage therefrom. The barrier layer is joined substantially about the second edge and the exterior side of the absorbent layer. The barrier layer is configured to prevent fluid flow therethrough.

Abstract: A hydrocarbon liquid-seal device is provided. The device includes first and second conduits in fluid communication with each other such that the first and second conduits define a flow path therethrough configured to pass a hydrocarbon vapor. The first and second conduits are in a spaced relationship and are not rigidly coupled to one another for isolating a vibration or movement respectively therein. The device further includes a liquid disposed within a space between first and second end portions of the first and second conduits, respectively, such that the liquid blocks the space between the first and second end portions and seals the hydrocarbon vapor in the flow path.

Abstract: 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.
