(EN) Microvalve that is doubly closed in a normal manner
الملخص
(EN)
A normally closed microvalve comprises a fluid inlet, a fluid outlet (332), a displaceable closure element (368, 370), which rests against a sealing lip when the microvalve is closed so that the fluid inlet is fluidically separated from the fluid outlet (332) and which is located at a distance from the sealing lip when the microvalve is open. The microvalve also comprises a displaceable retaining structure (310), which is connected to the closure element (368, 370) in such a manner as to create a space therebetween that is fluidically connected to the fluid inlet (332). An exertion of force upon the retaining structure (310) and upon the closure element (368, 370) in a first direction causes the microvalve to open, whereas an exertion of force upon the retaining structure (310) and upon the closure element (368, 370) in a second direction causes the microvalve to close. The fluid inlet and the closure element (368, 370) are arranged in such a manner that a pressure on the fluid inlet exerts a force in the second direction. An active surface of the retaining structure (310), which exerts a force in the second direction when a pressure is applied to the fluid outlet, is greater than an active surface of the closure element (368, 370), which exerts a force in the first direction when a pressure is applied to the fluid outlet.
