Abstract
A first flow path is connected to an inlet for introducing gas into a microvalve. A second flow path is connected to an outlet for allowing gas to flow out of the microvalve. A third flow path is for introducing a pneumatic fluid into the microvalve. A negative pressure generation mechanism (a pump) is for generating a negative pressure on the second flow path to suck gas from the first flow path forward the second flow path via the microvalve. A pressure adjustment mechanism (a connection flow path and a valve) is for reducing a pressure difference between the second flow path and the third flow path to prevent the inlet and the outlet from being blocked by a diaphragm layer in response to the negative pressure generated on the second flow path side.
