<p>PURPOSE:To provide a compact power generator with a hydraulic pump and a hydraulic motor well balanced by recovering to a certain extent a surplus flow of discharge pressure oil by hydraulic pump, by improving total system efficiency and by using a low-priced hydraulic motor. CONSTITUTION:Discharge hydraulic energy of a hydraulic pump 2 is stored in an accumulator 3 during high speed rotation of an engine 1. During low speed rotation of the engine 1, discharge pressure oil from the accumulator 3 is added to pump discharge pressure oil and supplied to an oil pump 8, and an AC generator 9 can supply required power at a constant rotating speed.</p> |
