Method for adjusting the volumetric flow ratio of at least two different fluids

A method for adjusting the volumetric flow ratio of at least two different fluids F1, F2, wherein the volumetric flow ratio between the fluids F1, F2 is adjusted with a control-device, comprising

• a first chamber with a chamber-volume VC1 for the first fluid F1, wherein the first chamber has an inlet-element and an outlet-element for the first fluid and at least one rotating or nutating element inside the chamber,
• at least one second chamber with a chamber-volume VC2 for the at least one second fluid F2, wherein the second chamber has an inlet-element and an outlet-element for the second fluid and at least one rotating or nutating element inside the chamber,
• wherein the at least one rotating or nutating element of the first chamber and the at least one rotating or nutating element of the second chamber are coupled so as to rotate or nutate at a defined rotational or nutational frequency ratio,
• wherein the at least one rotating or nutating element of the first chamber or the at least one rotating or nutating element of the second chamber are/is driven by the first fluid F1 and/or the second fluid F2,
• wherein the chamber volume ratio VC1:VC2 and the rotational or nutational frequency ratio are selected such that the first fluid flowing out of the outlet-element of the first chamber and the second fluid flowing out of the outlet-element of the second chamber have a predefined volumetric flow ratio
• and wherein the input resistor Ri of the respective inlet-element and the output resistor Ro of the respective outlet-element of the first chamber and/or the second chamber are chosen so as to satisfy the equation:
