The modulator is intended, under the control of a solenoid valve, for diverting a flow of fluid under high pressure from the fluid supply circuit of a hydraulic motor. The solenoid valve is a progressively acting solenoid valve, the shutter (70) of which is capable of more or less closing communication between the fluid inlet (56) and the inlet chamber (108) of the regulator as a function of the signal applied to the solenoid valve; furthermore, the spring (116) bears on a piston (132) which closes the regulating chamber (117) and behind which is formed a reaction chamber (128) communicating with the fluid inlet (56).
