<p>In this invention, the prime mover directly or through a slow-down gear train (2) winds up a spring device which may be a spiral spring or simply a rubber band (6). When the energy stored up is great enough, an adjustable stopper (8) automatically releases the spring device being latched which then activates the mechanism or drive the electric generator (9). After a certain amount of energy stored up is released, the latch will automatically be catched by the stopper. Hence the mechanism or the electric generator will be stopped and fluid energy will be started to store up again for the next release of the spring device.</p> |
