Abstract
Automatic gear change control device, in particular for a continuous torque converter or variator whose reduction ratio is controlled by a radial jack actuated by hydraulic pressure, characterized in that it comprises in combination a source of hydraulic fluid pressure such as a pump of oil, which pumps the oil into the tank; a first distributor comprising an inlet that communicates with the outlet under pressure of said source, a first outlet that communicates with a fluid pressure accumulator and a second outlet that communicates with said jack, when the distributor is in a first position and that it is closed when the distributor is in a second position, and a second distributor that joins said jack and the tank in a first position of said second distributor and that isolates them in a second position of said second distributor.
