  • Generator unit with clutch-driven pump
    Patent number: 6547527
    Abstract: A portable power unit having an internal combustion engine, a tank for holding a supply of pressurized fluid, an electrical generator powered by the internal combustion engine, and a pump selectively powered by the internal combustion engine. An electro-magnetic clutch is energized by a pressure switch on the tank when the pressure in the tank falls below a predetermined value, and a cooling fan for the pump may also be energized by the pressure switch together with the clutch. A non-slip positive drive belt couples power from the engine to the generator. The generator is overdriven at a shaft rotation speed above that of the engine's shaft, and the pump is underdriven at a shaft rotation speed below that of the engine's shaft.
