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, 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.
