To provide a power generator in a miniaturized configuration capable of supplying an oil to a screw expander without the need of an oil supply means such as an oil pump.
The power generator comprises a screw expander 11 having an expanding space for expanding a working medium, a working medium inlet 21, a working medium outlet 22, oil inlets 23, 24 and oil outlets 25, 26, a generator 12 connected with the screw expander 11, a condenser 13 for condensing a mixture of the working medium and the oil from the screw expander 11, a pump 14 for pressure feeding the mixture from the condenser 13, and an evaporator 15 for evaporating the working medium in the mixture for supplying, circulates and supplies the working medium from the evaporator 15 into the working medium inlet 21, and circulates and supplies the oil from the evaporator 15 into the oil inlets 23, 24. An oil separating tank 16 is disposed between the evaporator 15 and the screw expander 11 for separating the working medium and the oil, and the oil separating tank 16 and the oil inlets 23, 24 of the screw expander 11 are connected.
