US Patent:

56853963, Nov 11, 1997

Filed:

Sep 30, 1996

Appl. No.:

8/723497

Inventors:

Paul M. Elkin - Rancho Santa Margarita CA
Peter M. Elkin - Irvine CA
John Workings - Albuquerque NM
David Azarewicz - Tucson CA

Assignee:

Caylin Research and Development Corp. - Irvine CA

International Classification:

F16C 314

US Classification:

184 15

Abstract:

An environmentally sound apparatus for automatically extracting and injecting lubricating fluids is disclosed. The apparatus includes one or more sources of lubricating fluid, a waste fluid tank, and a source of compressed air, all with associated fluid-level sensing status switches, as well as other status switches for vacuum and low battery voltage. Signals from such status switches and from a fluid flow monitoring pulse meter are relayed to a central processing unit which operates through a front control panel to control a valved single pump and a plurality of valved lines in fluid communication with the single pump, and to display error messages to front control panel indicators when appropriate. Waste fluid is evacuated, from a crankcase oil pan of an internal combustion engine through one computer-determined arrangement of open valves and fluid lines, to the waste tank. Fresh fluid is injected, from one of the fluid sources through another computer-determined arrangement of open valves and fluid lines, to the oil pan.
