<p>As it is evident from the designs, the controller is an assembly of levers, a spring and a three-way valve and may set the pulley motor into operation at a repeated cycle by taking advantage of the pulley's motor (in order to operate). Operation thereof is based on storage of energy-power in a spring and, thereafter, on the creation of torsion which will rotate the three-way valve via a lever.</p> |
