Abstract

An air compressor with an internal combustion engine having an engine oil sump, a compressor driven by the internal combustion engine and having a compressor oil sump, and a controller coupled to the internal combustion engine. The controller is configured to halt the operation of the internal combustion engine in response to either a low oil condition in the engine oil sump or a low oil condition in the compressor oil sump. A method for the operation of an air compressor is also provided.

Claims

AMENDED CLAIMS[received by the International Bureau on 6 November 2006 (06.11.2006)]What is claimed is:
1. An air compressor system comprising: an internal combustion engine having an engine oil sump; an air compressor driven by the internal combustion engine, the air compressor having a compressor oil sump; and a controller coupled to the internal combustion engine, the controller halting operation of the internal combustion engine in response to a low oil condition in the engine oil sump, the controller also halting operation of the internal combustion engine in response to a low oil condition in the air compressor oil sump.
2. The air compressor system of Claim 1 , wherein the internal combustion engine includes an ignition circuit and the controller couples the ignition circuit to a ground to halt operation of the internal combustion engine.
3. The air compressor system of Claim 2, wherein the controller includes a latching circuit that latches in response to a low oil condition in either the engine oil sump or the air compressor oil sump and unlatches when operation of the internal combustion engine has been halted.
4. The air compressor system of Claim 1 , wherein the controller includes a first sensor that is disposed in contact with oil in the engine oil sump, the first sensor being responsive to an oil level in the engine oil sump.
5. The air compressor system of Claim 4, wherein the first sensor is a switch.
6. The air compressor system of Claim 5, wherein the switch is a float switch.
7. The air compressor system of Claim 4, wherein the controller includes a second sensor that is disposed in contact with oil in the air compressor oil sump, the second sensor being responsive to an oil level in the air compressor oil sump.
8. The air compressor system of Claim 7, wherein the second sensor is a switch.
9. The air compressor system of Claim 8, wherein the switch is a float switch.
10. An air compressor system comprising: an internal combustion engine with an engine lubricant therein; an air compressor driven by the internal combustion engine, the air compressor having a compressor lubricant therein; and a controller coupled to the internal combustion engine, the controller being responsive to a quantity of engine lubricant in the internal combustion engine and to a quantity of compressor lubricant in the compressor and effecting a cessation of operation of the internal combustion engine if either a quantity of engine lubricant is less than or equal to a first threshold quantity or a quantity of compressor lubricant is less than or equal to a second threshold quantity.
11. The air compressor system of Claim 10, wherein the controller includes a level sensor for monitoring at least one of the quantity of engine lubricant and the quantity of compressor lubricant.
12. The air compressor system of Claim 11 , wherein the level sensor is a float switch.
13. The air compressor system of Claim 12, wherein the float switch includes a reed switch and a float that contacts the reed switch to activate the float switch.
11
14. A method comprising: providing an air compressor system with an internal combustion engine and an air compressor; operating the internal combustion engine to power the air compressor; sensing a quantity of oil in the internal combustion engine; sensing a quantity of oil in the air compressor; and halting operation of the internal combustion engine if either a quantity of oil in the internal combustion engine is less than or equal to a first threshold or a quantity of oil in the air compressor is less than or equal to a second threshold.
15. The method of Claim 14, wherein halting operation of the internal combustion engine comprises coupling an ignition circuit of the internal combustion engine to a ground terminal.
16. The method of Claim 15, wherein after coupling the ignition circuit to the ground terminal, the method further comprises latching the ignition circuit to the ground terminal regardless of either the quantity of oil in the internal combustion engine or the quantity of oil in the air compressor.
17. The method of Claim 14, wherein sensing the quantity of oil in the internal combustion engine includes determining if the oil in the internal combustion engine is at or below a predetermined level.
18. The method of Claim 17, wherein determining if the oil in the internal combustion engine is at or below the predetermined level includes: locating a float sensor in a sump of the internal combustion engine, the sump holding at least a portion of oil in the internal combustion engine; and activating the float sensor when a level of the oil in the sump is less than or equal to a predetermined level.
19. The method of Claim 14, wherein sensing the quantity of oil in the compressor includes determining if the oil in the air compressor is at or below a predetermined level.
12
AMENDED SHEET (ARTICLE Ig)
20. The method of Claim 19, wherein determining if the oil in the air compressor is at or below the predetermined level includes: locating a float sensor in a sump of the compressor, the sump holding at least a portion of oil in the air compressor; and activating the float sensor when a level of the oil in the sump is less than or equal to a predetermined level.
