Abstract
The microvalve comprises a mini-piston moving due to the thrust of gases given off by firing of a pyrotechnic charge and comprising an aperture designed to enable communication to be established between ends of microchannels of a microfluidic component. When the ends between which communication is to be established open out onto a face of a first planar substrate, the mini-piston is formed in a second planar substrate, adjoined to the first, and comprises a part that is mobile in translation or in rotation in the plane of the second substrate. If a transverse slot is arranged between the ends of the microchannels between which communication is to be established, the mini-piston comprises a rod designed to slide in the slot and the aperture is formed by a transverse orifice formed in the rod of the mini-piston.
