PURPOSE:To put a magnet provided piston in a reciprocating motion by a method wherein repulsive or attractive magnet is generated alternately by a method wherein a magnetic pole on the lower side of an electromagnet is automatically turned N and then S synchronous with the reaching the top dead center or the bottom dead center of said piston. CONSTITUTION:A magnet 4 is fixed on the top side of a piston 3 with the N pole up and S pole down. Installed opposed to the magnet 4 is an electromagnet 5. When a power switch 39 is closed with the magnet 4 at the top dead center, the coil wire 5-2 of the electromagnet 5 is energized in the direction from an upper A end 5-2A down to a lower B end 5-2B, the resulting magnetic force repulsing the magnet 4 downwards. Arrival at the bottom dead center of the magnet 4 switches over a rotary distributor K dist. 14, rotary power switches AK21 and BK28, resulting in a current flow in the coil wire 5-2 in the direction from a lower B end 5-2B to an upper A end 5-2A, the resulting magnetic force attracting the magnet 4 upwards. |
