Abstract:
1. An air compressor system comprising: an internal combustion engine having an engine oil sump and an ignition circuit that outputs electrical energy to initiate a combustion event; an air compressor driven by the internal combustion engine, the air compressor having a compressor oil sump; a single control circuit comprising a thrysistor having a first terminal, which is coupled to the ignition circuit, and a second terminal that is coupled an electrical ground; a first sensor for sensing a level of a first lubricant in the engine oil sump, the first sensor generating a first sensor signal when the level of the first lubricant in the engine oil sump is less than a predetermined first threshold; and a second sensor for sensing a level of a second lubricant in the compressor oil sump, the second sensor generating a second sensor signal when the level of the second lubricant in the compressor oil sump is less than a predetermined second threshold; wherein the first and second sensors are coupled in parallel between the ignition circuit and the electrical ground.
