A hydraulic circuit for the transmissions of industrial and agricultural vehicles comprises a feed pump driven by an internal combustion engine, a lubricating circuit, a main pressure regulator capable of bringing about a first change in the pressure of the working fluid in the circuit, this change in pressure being capable of regulation in relation to a first regulation pressure and a maximum pressure regulator for the lubrication circuit capable of bringing about a second change in pressure of the working fluid depending upon a second regulating pressure and means for regulating regulation of the said first and second regulating pressures.
