摘要：
The invention relates to a device (10) for hydraulically controlling a gearbox including at least one sliding gear set in motion by a fork, comprising at least one hydraulic actuator (21) capable of moving the fork and at least one solenoid valve (19, 20) that is capable of changing the state of the hydraulic actuator (21) by means of the pressure differential between a high-pressure accumulator (11) and a low-pressure accumulator (15). The device is characterized in that it further comprises a very high-pressure accumulator (27), the pressure differential between the low-pressure accumulator (15) and the very low-pressure accumulator (27) enabling the solenoid valve (19, 20) to change the state of the actuator (21).
