Appl. No.:

8/681989

Willie Luther Stamey - Kings Mountain NC

Christopher Louis Loafman - Gastonia NC

Assignee:

Dana Corporation - Toledo OH

International Classification:

B01D 35147

US Classification:

210131

Abstract:

Flow inverter arrangements are provided for utilization in spin-on, liquid filter cartridges, such as lubricating oil filter cartridges and the like, wherein the filter cartridge structure normally used for "inside-out" flow is reversed to accommodate "outside-in" flow. Each embodiment of the invention utilizes a cylindrical wall disposed within the hollow core of a filter media, in spaced relation thereto, so as to define an annular space which is aligned with the input ports in the end plate of the housing. A filter media has a first end cap within an opening aligned with the central core so that liquid which is passed from the annular space and through the filter media can pass through the opening in the end cap and to the central port which is aligned with the hollow core of the filter media, but isolated from the filter media by the interior wall. The entire filter element is shifted axially against the bias of the coil spring when the filter media becomes clogged so that the filter media can be bypassed. In one embodiment, an anti-drainback valve is provided at the central opening through the first end cap to prevent liquid in the filter cartridge from completely draining therefrom when it is not pressurized by, for example, operation of a pump such as the lubricating oil pump of an internal combustion engine.

US Classification:

210206

Abstract:

An inline cartridge filter for treating coolant liquid used to cool industrial application such as cooling towers and chillers, combustion engine includes an annular filter media disposed around a cylindrical biological control element which includes a biocide for controlling the growth of bacteria and a pH control agent for controlling the growth of algae in the coolant liquid. The filter media and biological control element form a disposable filter element which is mounted in a housing.

Dana Corporation - Toledo OH

International Classification:

B01D 2714

US Classification:

210316

Abstract:

A dual-flow lubricant filter assembly having a bypass filter element with a full-flow filter element stacked thereon includes a grommet disposed between the filter elements for isolating lubricant streams after the lubricant has passed through the filter elements. The grommet is molded of a resinous material and includes an external flange which is sandwiched between the bypass and full-flow filter elements in order to axially position the grommet. The grommet also includes an internal flange which seals with an unthreaded portion of a standpipe with which the filter assembly is coupled.

International Classification:

US Classification:

137203

Abstract:

A self-venting valve having its principal parts molded of nylon reinforced with glass fibers is mounted in the bottom of a fuel filter assembly to drain water and other contaminants from the assembly. The self-venting valve includes a plunger portion with a bore therethrough for draining water from the fuel filter assembly and a valve body member which receives the plunger. The valve body member has a vent hole therein which communicates with the interior of the housing to let air into the housing so that as the water drains from the housing a partial vacuum is not created which might interrupt the flow of water. The plunger is biased to the valve closed position by a coil spring, however the valve may be held in the open position by misaligning lugs on the plunger with slots in the valve body member.
