Abstract
Method for adjusting the volumetric flow ratio of at least two different fluids (F1, F2) with a control-device. The control-device comprises a first chamber with a chamber-volume (VC1) for the first fluid (F1) and an inlet-element and an outlet-element for the first fluid (F1) and at least one rotating or nutating element. The control-device further comprises at least one second chamber with a chamber-volume (VC2) for the second fluid (F2), wherein the second chamber has an inlet-element and an outlet-element for the second fluid (F2) and at least one rotating or nutating element. The rotating or nutating elements are coupled so as to rotate or nutate at a defined rotational or nutational frequency ratio and are driven by the fluids (F1, F2). The chamber volume ratio (VC1:VC2) and the rotational or nutational frequency ratio are selected such that the fluids (F1, F2) flowing out of the outlet-elements have a predefined volumetric flow ratio. 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: (I), wherein ηF is the viscosity of t…
