Assignee:

Honeywell International Inc. - Morristown NJ

International Classification:

B01D 3502

US Classification:

210443, 210DIG 17

Abstract:

A filter assembly is provided having a generally cylindrical housing defining a housing edge. A filtering element is disposed in the housing for filtering the fluid. A generally circular unitary tapping plate is also provided having a fluid inlet port, a fluid outlet port, and mounting means for removably mounting the filter assembly to the fluid circulation system. The unitary tapping plate further having a generally U-shaped portion defining an inboard seal retaining groove and a wing portion extending radially outwardly from said U-shaped portion. The edge of the housing surrounds the tapping plate and is folded inwardly over the wing portion of the tapping plate such that a free end of the housing edge generally terminates in the seal-retaining groove. The filter assembly also includes an external seal having a generally rectangular cross-section that is retained in the seal retaining groove. The wing portion of the tapping plate enables the outer diameter of the housing and the filtration area of the filtering element to be increased, without increasing the diameter of the external seal.

US Classification:

210314

Abstract:

A filter of the type having first annular filter media comprising a generally columnar stack of annular filter media lamina for providing filtration for one circuit, a harness for retaining the filter media lamina in stacked columnar alignment comprising a generally circular end piece having a diameter somewhat greater than the diameter of the filter media lamina engaging one end lamina, an annular portion engaging the opposite end lamina, a plurality of elongated strips integral with and extending from the periphery of the annular portion with the end piece receiving and retaining the free ends of the elongated strips. There is a second filter media providing filtration for another circuit. The two filter media are housed adjacent to one another in a hollow cylindrical shell closed at one end. An annular retainer is integral with the shell near the other shell end for engaging the second media and retaining both media axially within the shell.

International Classification:

B01D 3502

US Classification:

210443

Abstract:

A filter assembly is provided having a housing defining a housing edge. A tapping plate is also provided and is generally circular in shape. The tapping plate defines a tapping plate edge and includes a fluid inlet port and a fluid outlet port. Preferably, the at least one fluid outlet port is a central threaded aperture to enable the filter assembly to be secured to a filter mount of an engine. An interconnecting device is included for interconnecting the housing and the tapping plate. The interconnecting device further retains an external seal generally about the tapping plate edge. The external seal is an economically formed lathe-cut gasket and the interconnecting device includes a first and second extension member. The first extension member is formed integrally with the tapping plate at the tapping plate edge. The second extension member is formed integrally with the housing at the housing edge.

Abstract:

A coolant filter kit, for attaching in-line to a coolant hose of a combustion engine, includes a fluid conduit member and a coolant filter apparatus. The fluid conduit member has a stem and two opposed branches connected to the stem, with an inlet formed in a first branch thereof, and an outlet formed in a second branch. The fluid conduit member further has a partition in the stem thereof, substantially separating a first flow chamber from a second flow chamber therewithin. In a preferred embodiment of the invention, a limited amount of fluid is allowed to flow directly from the inlet to the outlet without passing through the filter apparatus. The filter apparatus includes a hollow housing defining a filter chamber therein. A porous cylindrical filter element is disposed in the filter chamber of the housing. Optionally, the filter apparatus may include a slow-dissolving tablet or plug for releasing a supplemental coolant additive into coolant over time.
