The present invention relates to an emulsion-producing hydraulic circuit. The hydraulic circuit includes a by-pass loop comprising a first end and a second end, where the first end of the by-pass loop and the second end of the by -pass loop are connected to a supply line of the hydraulic circuit before and after a pump. The asynchronous by-pass loop also includes a control valve, and the by-pass loop transfers a portion of an emulsion and/or any separated liquid that has accumulated in the hydraulic circuit to the supply line to be re- emulsified. Also disclosed is a method for re-emulsifying a separated liquid present in a hydraulic circuit.
