Abstract
Abstract A centrifugal filter separator operable to separate from oil under pressure solid contaminants by depositing them on the internal wall of a rotating drum, powered by reaction jet nozzles and to separate water from oil and extract it from the rotating drum. The rotating drum is composed of two cups held together by a shaft, passing through the axis of rotation of the drum and mounting a water extraction mechanism, which can be removed from the shaft during cleaning of the internal wall of the drum of the deposited solid contaminants.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
111 words
A centrifugal filter separator assembly comprising a stationary housing having a pressurized oil inlet port, a clean oil outlet port, and a centrifuged water port, a rotatable drum journalled in said housing for rotation on an upright axis, means interconnecting said oil inlet port with internal space enclosed by said drum, at least one reaction jet nozzle carried by said drum and connected with said internal space, and means for removing water from said drum including means to slide radially outwardly in response to centrifugal force, sufficient to provide automatic alignment and balancing during operation, and to manually slide inwardly during rest to provide easy removal thereof from the solid contaminants.
Claim 2
Dependent Claim
111 words
A centrifugal filter separator assembly comprising a stationary housing having a pressurized oil inlet port, a clean oil outlet port, and a centrifuged water port, a rotatable drum journalled in said housing for rotation on an upright axis, means interconnecting said oil inlet port with internal space enclosed by said drum, at least one reaction jet nozzle carried by said drum and connected with said internal space, and means for removing water from said drum including means to slide radially outwardly in response to centrifugal force, sufficient to provide automatic alignment and balancing during operation, and to manually slide inwardly during rest to provide easy removal thereof from the solid contaminants.
Claim 3
Dependent Claim
30 words
A centrifugal filter separator as set forth in claim 1 wherein said means for removing water from said drum includes sleeve means slidably mounted in respect to a shaft means.
Claim 4
Dependent Claim
24 words
A centrifugal filter separator as set forth in claim 2 wherein said sleeve means includes water conducting tube means mounted on said sleeve means.
Claim 5
Dependent Claim
46 words
A centrifugal filter separator as set forth in claim 1 wherein said means for removing water from said drum includes radially spaced water conducting tube means and means slidably mounting said water conducting tube means in respect to said means for removing water from said drum.
Claim 6
Dependent Claim
28 words
A centrifugal filter separator as set forth in claim 4 wherein said radially spaced water conducting tube means has means abutting with said interior surface of said drum.
Claim 7
Dependent Claim
25 words
A centrifugal filter separator as set forth in claim 5 wherein said means abutting with said interior surface of said drum has flow slot means.
