Abstract:
A system that supplies electrical power and compressed air, the system comprising:a. an engine comprising a throttle having a first position for relatively higher speed and a second position for relatively lower speed; b. a compressor in mechanical communication with the engine for receiving operative power; c. a generator in mechanical communication with the engine for receiving operative power, the generator for supplying the electrical power; d. a reservoir in fluid communication with the compressor to receive air compressed by the compressor, compressed air being supplied from the reservoir; and e. a controller that moves the throttle from the first position to the second position in response-to sensing a magnitude of the supplied electrical power and sensing a pressure of air in the reservoir; wherein the controller comprises a current sensor electrically coupled to at least a portion of the supplied electrical power, the current sensor providing a first signal in response to the portion of supplied electrical power, the controller moving the throttle in further response to the first signal.
