Patent ID: 8723345

Claim:
A portable generator comprising: a fluid pressure generator for generating a fluid pressure by pumping and pressurized moving in a direction of non-compressible fluid in a fluid-storing space, the fluid pressure generator including an airbag for compensating a volume change by the pressurized moving of the non-compressible fluid; a fluid pressure cylinder connected to the fluid pressure generator and comprising a fluid pressure piston forced to proceed by pressurizing the fluid in a cylinder tube through the pressurized moving, a gas piston, and a piston rod connecting the fluid pressure piston and the gas piston; a gas power generator comprising a high pressure gas chamber charged with a high pressure gas compressed by a volume of the piston rod proceeding an initial charging pressure of the piston rod imparted by the proceeding of the fluid pressure piston, the piston rod, and the gas piston of the fluid pressure cylinder and a cycle path connecting a flow of the high pressure gas between the high pressure gas chamber of the piston rod and another high pressure gas chamber in front of the piston through a gas generator in the rear; the gas generator for generating electricity with a flow of the high pressure gas moving in the high pressure gas chamber as a power source; and a charger comprising a PCB circuit board for rectifying electricity generated by the gas generator into a DC level and a display connected electrically to the PCB circuit board so as to control a charging voltage and display a status of charging.
