Abstract
Device for the hydraulic regulation of the rotation of two shafts driven respectively by a first hydraulic motor and a second hydraulic motor (20, 18) supplied with hydraulic fluid from a common source to which they are connected in series by means of respective directional control valves (21, 25), characterised in that the downstream terminal of the first hydraulic motor (20) is connected to the downstream terminal of the second hydraulic motor (18) by means of a sequential valve (28) set for a predetermined pressure value and connected to the upstream terminal of the first motor (20) and designed, by opening, to cause the second motor to stop when the pressure on the upstream terminal of the first motor reaches the said predetermined value.
