Abstract

Abstract A centrifuge for processing a flow of oil in order to remove particulate matter includes a mounting base defining a drain passageway, a drain conduit connected to the mounting base, a unitary housing connected to the mounting base, and a cone-stack subassembly which is positioned in and cooperates with the unitary housing. The mounting base is constructed and arranged to mount directly to a portion of a vehicle engine (or other equipment) and the drain conduit provides a return path to sump for oil from a remote engine (or equipment) location. The unitary housing is an injection molded plastic component including both a main body portion and an integral oil fill port. The oil fill port is substantially cylindrical with a longitudinal axis which is parallel to the axis of rotation for the rotor portion of the centrifuge.

Claims Analysis

Total Claims: 8
Claim 1
Independent Claim 170 words
A centrifuge for processing a flow of oil, said centrifuge comprising: a mounting base defining a drain passageway; a unitary housing connected to said mounting base and including a main body and an integral oil fill port, said main body including a lower edge arranged with a plurality of spaced-apart strengthening ribs; centrifugal separation means for separating particulate matter from said flow of oil, said centrifugal separation means being positioned in and cooperating with said unitary housing; said unitary housing defining a centered aperture for use in assembly of a cone-stack subassembly and connection of said centrifuge housing to said mounting base; said integral oil fill port and said centered aperture being concentric to each other; said unitary housing including an inner wall positioned between said integral oil fill port and said centered aperture; and said inner wall and an outer wall of said centered aperture being connected by spaced-apart webs which define clearance openings for the flow of oil into said unitary housing via said integral oil fill port.
Claim 2
Dependent Claim 170 words
A centrifuge for processing a flow of oil, said centrifuge comprising: a mounting base defining a drain passageway; a unitary housing connected to said mounting base and including a main body and an integral oil fill port, said main body including a lower edge arranged with a plurality of spaced-apart strengthening ribs; centrifugal separation means for separating particulate matter from said flow of oil, said centrifugal separation means being positioned in and cooperating with said unitary housing; said unitary housing defining a centered aperture for use in assembly of a cone-stack subassembly and connection of said centrifuge housing to said mounting base; said integral oil fill port and said centered aperture being concentric to each other; said unitary housing including an inner wall positioned between said integral oil fill port and said centered aperture; and said inner wall and an outer wall of said centered aperture being connected by spaced-apart webs which define clearance openings for the flow of oil into said unitary housing via said integral oil fill port.
Claim 3
Dependent Claim 200 words
A self-driven, cone-stack centrifuge for use in an engine for processing a flow of oil, said cone-stack centrifuge comprising: a mounting base defining a drain passageway and including a support plate which is constructed and arranged to be attached to said engine; a unitary centrifuge housing connected to said mounting base, said centrifuge housing including a main body and an integral oil fill port; a cone-stack subassembly for separating particulate matter from said flow of oil, said cone-stack subassembly being positioned in and cooperating with said unitary housing; said centrifuge housing defining a centered aperture for use in assembly of said cone-stack subassembly and connection of said centrifuge housing to said mounting base; said integral oil fill port and said centered aperture being concentric to each other; said centrifuge housing including a top portion and said integral oil fill port being integral with said top portion; said centrifuge housing including an inner wall positioned between said integral oil fill port and said centered aperture; and said inner wall and an outer wall of said centered aperture being connected by spaced-apart webs which define clearance openings for the flow of oil into said centrifuge housing via said integral oil fill port.
Claim 4
Dependent Claim 200 words
A self-driven, cone-stack centrifuge for use in an engine for processing a flow of oil, said cone-stack centrifuge comprising: a mounting base defining a drain passageway and including a support plate which is constructed and arranged to be attached to said engine; a unitary centrifuge housing connected to said mounting base, said centrifuge housing including a main body and an integral oil fill port; a cone-stack subassembly for separating particulate matter from said flow of oil, said cone-stack subassembly being positioned in and cooperating with said unitary housing; said centrifuge housing defining a centered aperture for use in assembly of said cone-stack subassembly and connection of said centrifuge housing to said mounting base; said integral oil fill port and said centered aperture being concentric to each other; said centrifuge housing including a top portion and said integral oil fill port being integral with said top portion; said centrifuge housing including an inner wall positioned between said integral oil fill port and said centered aperture; and said inner wall and an outer wall of said centered aperture being connected by spaced-apart webs which define clearance openings for the flow of oil into said centrifuge housing via said integral oil fill port.
