ABSTRACT:
Contaminating particles in lubricating oil have a density higher than the density of the oil. The present invention provides a device for removing the contaminating particles by settling out the heavier particles and separating them from the oil.
The device comprises means to establish laminar horizontal flow and means to withdraw sinking particles vertically over the bottom surface of the horizontally flowing oil. In its preferred embodiment the device has a pressure tight cylindrical settling chamber over a hemispherical sump which are separated by a foraminous partition of elongated, slender vertical passages. Oil inlet means introduce oil diverted from the oil line of the lubricating system in vertically related horizontal streamlets into the oil in the separating chamber which flows horizontally through it over the foraminous partition where falling particles settle out and to outlet means where similar vertically related horizontal streamlets are removed to rejoin the oil stream from which it was diverted. The sump is provided with a pet cock to remove particle laden oil from time to time. An equal volume of clean oil is then added to the system.
The device is effective in keeping oil in good condition indefinitely and avoid periodic oil changes such as are required by the present practice of filtering.
