Zusammenfassung:	The present invention relates to an automatic gear box and a control therefor of a motor vehicle, including two pulleys connected by a transmission belt (driving belt), each of which is formed by a couple of disks, of which one is movable in regard to the other one, in order to vary the winding radius of the belt. The control for the automatic gear box includes an hydraulic circuit which incorporates a number of actuating cylinders, a couple of delaying valves and a valve for issuing a fluid gradually and under increasing pressure only if the inlet pressure is above a preestablished value.
