Abstract

Abstract The centrifuge has a two-part rotor provided with two sets of outlets. One set ejects fluid in the form of jets so as to drive the centrifuge. The second set ejects fluid which has been cleaned. Outlets are also provided for the contaminants removed from the cleaned fluid. The liquid flow rate for the drive is high while the flow rate for centrifuging can be low or medium. The liquid flows can be delivered from different sources.

Claims Analysis

Total Claims: 6
Claim 1
Independent Claim 102 words
The combination of a centrifuge having a hollow rotor including a separating chamber having an inlet for liquid to be cleaned and a first outlet for expelling cleaned liquid outwardly of said rotor, and a drive chamber having a second outlet for expelling a jet of liquid outwardly of said rotor to impart a rotary force on said rotor; a tank connected to said first outlet to receive cleaned liquid therefrom; and a pump having a suction line connected to said tank and a delivery line connected to said drive chamber to deliver cleaned liquid from said tank to said drive chamber.
Claim 2
Dependent Claim 102 words
The combination of a centrifuge having a hollow rotor including a separating chamber having an inlet for liquid to be cleaned and a first outlet for expelling cleaned liquid outwardly of said rotor, and a drive chamber having a second outlet for expelling a jet of liquid outwardly of said rotor to impart a rotary force on said rotor; a tank connected to said first outlet to receive cleaned liquid therefrom; and a pump having a suction line connected to said tank and a delivery line connected to said drive chamber to deliver cleaned liquid from said tank to said drive chamber.
Claim 3
Dependent Claim 44 words
The combination as set forth in claim 1 which further includes a branch line connected to said delivery line and to said separating chamber, and an ejector in said branch line for drawing liquid to be cleaned from said tank into said branch line.
Claim 4
Dependent Claim 35 words
The combination as set forth in claim 1 which further includes a float in said tank having an inlet connected to said ejector to draw liquid from adjacent the surface of liquid in said tank.
Claim 5
Dependent Claim 33 words
The combination as set forth in claim 1 wherein said tank and said pump connected to an internAl combustion engine with said centrifuge being connected to clean a cooling liquid of said engine.
Claim 6
Dependent Claim 49 words
The combination as set forth in claim 1 which further includes a second tank connected to said first tank to receive clean liquid therefrom and to said suction line of said pump to deliver clean liquid thereto, and a reservoir connected to said centrifuge to receive separated oil therefrom.
