To provide a new kind of power machine requiring no fossile fuel by which pollution is generated, by forming high-pressure liquid through a process of compressing liquid such as hydraulic oil or liquid poured in a liquid pressure container by gravity, by transmitting it to a torque generating device, and by rotating a plurality of active cylinders also serving as rotary shafts.

High-pressure liquid is formed by compressing liquid such as hydraulic oil or liquid poured in a liquid pressure container, and the formed high-pressure liquid is transmitted to a torque generating device to rotate a plurality of active cylinders also serving as rotary shafts. A source pressurizer 8 is composed of a straight erecting cylinder 9 erected on the left end, a straight erecting cylinder 11 erected on the right end, and a horizontally arranged cylinder 13 extending between them. The upper parts of the straight erecting cylinders 9, 11 are upper opening parts 10 through which a liquid pressurizer is inserted and connected, cylindrical parts on the lower parts of the upper opening parts 10 are hollow bodies and extend to facing opening parts of pressure transmitting cylinders connected to the horizontally arranged cylinder 13 into a T shape.
