Abstract

See full text

Microscale valves for use in, e.g., micropump devices, may be formed of a slitted diaphragm bonded to the interior of a valve tube. A bump in the diaphragm and/or a backward-leakage stopper may increase the breakdown pressure of the valve. A push-rod may be used to pre-load the valve membrane to thereby increase the cracking pressure.
