<p>A speed regulator (2) has its mobile element subjected to centrifugal force via masses (13) rotating at a speed proportional to that of the transmission output shaft. A elastically yieldable element e.g. a piston (18) can be controlled to act on the mobile regulator element in opposition to the thrust of the centrifugal masses. - The regulator slides on a rectilinear guide and rests against the ends of a lever. The elastically yieldable element comprises a preloaded element slidable on a fixed seat between operating and non-operating positions i.e. engaged or separated from the lever, An exponential characteristic spring is preloaded via the engine feed control.</p> |
