Self-balancing high-speed free piston generator

The invention relates to energy power engineering machinery, in particular to a self-balancing high-speed free piston generator and belongs to the field of energy power. The self-balancing high-speed free piston generator mainly comprises a free piston internal combustion engine, a plat linear generator, a gas pumping device, a driving and reversing device and a one-way air inlet valve. Since a primary generator and a secondary generator move synchronously yet reversely, cutting speed of the secondary generator is increased to twice as that of movement of a piston, and operation efficiency is improved.
