Device for controlling a hydraulic boost motor providing secondary circulation of hydraulic fluid in the said hydraulic motor (1) in order to lubricate it when the distributor device (2) calls for the boosting to be cut off. This device includes a valve (10) mounted in parallel with the said motor (1) between pipes (14, 15) connected to the primary feed circuit on either side of the said motor, and which is driven hydraulically via its existing pipes arriving at the said motor, without it being necessary to add a special pipeline, in order to pass from a position I for which it establishes the communication between the pipes (14, 15) located on either side of the motor to a position II for which it cuts off this communication. <IMAGE>
