A power plant for generating electric power and pneumatic pressure includes an internal combustion engine, an electrical generator, and a compressor and pneumatic supply tanks. Both the electrical generator and the compressor are driven by the engine, however, the engine drive is so coupled and controlled that the engine drives the generator as its primary load, and the compressor as its secondary load and apportions the engine power between these units according to need. When the generator uses all the engine power, pneumatic power is supplied by the pneumatic supply tanks, permitting a smaller than normal drive engine. A quick start and quick kill mechanism is provided for the engine by using the air supply from the pneumatic supply tank and an air motor, and a time delay shut down relay when no power is being used. Also the generator can be used as an electric drive motor for the compressor in place of the internal combustion engine, where 110 volt power is available on the job site.
In a power plant for driving at least one power supply for the provision of electrical or pneumatic power to an operator controlled power tool, by selectively driving one or both of an electric generator or pneumatic compressor, each of which being selectively connected to the tool, and a drive engine for providing motive power to the power supplies, the improvement comprising:
In a power plant for generating electric power and pneumatic power by selectively driving one or both of an electrical power generator unit and a pneumatic power compressor with an air storage tank unit, and having a single drive engine, control means for starting up and shutting down said power plant comprising:
