Simple SummaryContent extracted from patent full text and abstract with AI.

This patent describes a micropump that uses a diaphragm extending across a fluid channel, combined with a specifically designed fluid component, to create controlled, directional fluid movement. The design ensures that fluid flows more easily in one direction than the other when the diaphragm moves back and forth, resulting in effective pumping.

Patent Abstract

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. An independent claim is included for a method for pumping of fluid with a micropump.
