Abstract:
A fluid handling device has fluidic structures having inlet and outlet chambers and a connecting duct fluidically connecting the two. In a first state, the inlet chamber is completely or partly filled with at least a liquid and partly filled with a compressible medium, and the outlet chamber is at least partly filled with the compressible medium. One of the inlet chamber and the outlet chamber has such a venting duct that a flow resistance/volume product of venting of the chamber for the compressible medium amounts to at least 6700 N·s/m 2 , the other of the inlet chamber and of the outlet chamber being vented. An actuator for actuating the fluidic structures is to cause a pressure difference of at least 30 Pa between the compressible media within the inlet and outlet chambers, so as to thereby switch a valve device implemented into the connecting duct.

Claim (Index 1):
Fluid handling device comprising:\n fluidic structures comprising at least one inlet chamber, one outlet chamber, and a connecting duct which fluidically connects the inlet chamber to the outlet chamber, wherein in a first state, the inlet chamber is completely filled with at least a liquid or partly filled with at least a liquid and partly filled with a compressible medium, and the outlet chamber is at least partly filled with the compressible medium, wherein one of the inlet chamber and the outlet chamber comprises such a venting duct that a flow resistance/volume product of venting of said chamber for the compressible medium amounts to at least 6700 \ue89e N \u00b7 s m 2 , the other of the inlet chamber and of the outlet chamber being vented,\n an actuator for actuating the fluidic structures on the basis of the first state so as to cause, due to different pressure equalization rates of the inlet chamber and of the outlet chamber, which are due to different flow resistance/volume products, a pressure difference of at least 30 Pa between the compressible medium within the inlet chamber and the compressible medium within the outlet chamber, \n so as to thereby switch a valve device implemented into the connecting duct, such that liquid gets from the inlet chamber into the outlet chamber, or so as to thus temporarily counteract a flow, caused by the actuation, from the inlet chamber into the outlet chamber, \n wherein the respective flow resistance/volume product is defined by the product resulting from the volume of the respective chamber and a fluidic resistance Rrf of the respective venting duct, comprising \n R fl = C geometry \u00b7 \u03b7 \ue89e \ue89e l A 2 wherein C geometry  is a geometry-dependent factor, \u03b7 is the viscosity of the compressible medium, l is the length of the respective venting duct, and A is the cross sectional area of the respective venting duct.
