Mikropumpe und Verfahren zum Pumpen eines Fluids

DE 102008004147 A1 UPAB: 20090728 NOVELTY - The micropump (1) has a diaphragm (2), which is extended over a cross section of a fluid channel (10), and has a fluid component (4) with a passage (4a) by the diaphragm. The fluid component is formed in such a manner that the flow resistance by the fluid component during a deflection of the diaphragm is larger in a direction than flow resistance by the fluid component during a deflection of diaphragm in another direction. The reciprocating deflection of diaphragm causes net fluid current by fluid component in former direction. The diaphragm has a metal, plastic, glass, ceramic or silicon. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for pumping of fluid with a micropump. USE - Micropump for pumping of fluid. ADVANTAGE - The fluid component is formed in such a manner that the flow resistance by the fluid component during a deflection of the diaphragm is larger in a direction than flow resistance by the fluid component during a deflection of the diaphragm in another direction, and reciprocating deflection of the diaphragm causes a net fluid current by the fluid component in former direction, and hence ensures an economical pumping of fluid
