Abstract

Abstract An adapter is mounted between an engine and a standard oil filter connected to a hydraulic motor which drives a centrifugal drum, the adapter also delivers metered quantities of the oil to an inside of the centrifugal drum, and an outlet from the centrifugal drum returns the oil to the engine, an outlet from the hydraulic motor returns the oil to the adapter to pass through the standard oil filter before being returned to the engine.

Claims Analysis

Total Claims: 3
Claim 1
Independent Claim 217 words
An oil cleaning system, comprising: An adapter mounted on an engine block in communication with the oil outlet of said engine block, and a standard oil filter, mounted directly on said adapter, A pipe connected to the adapter for carrying oil to a valve, A hydraulic motor connected to the pipe, said motor having means for returning oil through the adapter so as to pass the oil through the standard oil filter, An oil inlet connected to the valve and passing through a cover into a centrifugal drum, said valve functioning to distribute oil flow from said adapter, between said oil outlet and said hydraulic motor, the cover sealably mounted to a housing, means for rotatably supporting an upper end of the centrifugal drum attached to the cover and surrounding the inlet pipe, a drive shaft extending from the hydraulic motor engaging a bottom surface of the centrifugal drum and supported by a bearing at a bottom of the housing to rotate the centrifugal drum, an outlet from the centrifugal drum at an upper surface of the centrifugal drum thereof to permit oil to leave the centrifugal drum and pass along a wall of the housing to an outlet from the housing, and means of returning the oil to the engine from the outlet from the housing.
Claim 2
Dependent Claim 217 words
An oil cleaning system, comprising: An adapter mounted on an engine block in communication with the oil outlet of said engine block, and a standard oil filter, mounted directly on said adapter, A pipe connected to the adapter for carrying oil to a valve, A hydraulic motor connected to the pipe, said motor having means for returning oil through the adapter so as to pass the oil through the standard oil filter, An oil inlet connected to the valve and passing through a cover into a centrifugal drum, said valve functioning to distribute oil flow from said adapter, between said oil outlet and said hydraulic motor, the cover sealably mounted to a housing, means for rotatably supporting an upper end of the centrifugal drum attached to the cover and surrounding the inlet pipe, a drive shaft extending from the hydraulic motor engaging a bottom surface of the centrifugal drum and supported by a bearing at a bottom of the housing to rotate the centrifugal drum, an outlet from the centrifugal drum at an upper surface of the centrifugal drum thereof to permit oil to leave the centrifugal drum and pass along a wall of the housing to an outlet from the housing, and means of returning the oil to the engine from the outlet from the housing.
Claim 3
Dependent Claim 65 words
The centrifugal oil cleaner of claim 1 wherein a distal end of the drive shaft has a spline, the bottom surface of the centrifugal drum has a spline receiver for receiving the splined distal end of the drive shaft, and the upper surface of the centrifugal drum has a neck journaled in a bearing mounted in the cover of the housing of the centrifugal cleaner.
