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.
Claims20
An air compressor comprising:
- an internal combustion engine having an engine oil sump;
- a compressor driven by the internal combustion engine, the 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 compressor oil sump.
1 more element
An air compressor comprising:
- an internal combustion engine with an engine lubricant therein;
- a compressor driven by the internal combustion engine, the 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.
1 more element
A method comprising:
- providing an air compressor with an internal combustion engine and a compressor;
- operating the internal combustion engine to power the compressor;
- sensing a quantity of oil in the internal combustion engine;
- sensing a quantity of oil in the 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 compressor is less than or equal to a second threshold.
