Abstract:
1. A mechanical energy storage system comprising: a pressure vessel cylinder charged with a high pressure gas and sealed from outside; a piston installed in a cylinder chamber of the pressure vessel cylinder and dividing sealingly the cylinder chamber into front and rear cylinder chambers; a piston rod installed sealingly from outside penetrating the rear cylinder chamber of the piston and push-and-moved by an external mechanical force; a first check valve providing the moving of the high pressure gas in a direction from the front cylinder chamber to the rear cylinder chamber for compression equilibrium of the high pressure gas according to the proceeding movement of the piston; a first tube path connected sealingly to the rear cylinder chamber for discharging stored energy of reacting force against compression by volume displacing amount due to the proceeding movement of the piston; a control valve installed in the first tube path for controlling speed and amount of discharged high pressure gas; a gas generator connected to the first tube path and powered by the high pressure gas moved by controlling the control valve; a second tube path connected sealingly so as to return the high pressure gas used to power the gas generator to the front cylinder chamber; and a second check valve installed in the second tube path for preventing backflow of the high pressure gas to the gas generator, wherein all components are maintained to be sealed in a state of being sealed off from outside and being charged with the high pressure gas in a pressurized equilibrium.
