Abstract
The present invention is inherent to a shape memory alloy actuated fluidic subassembly (10) and to an equipment incorporating it as dispensing device, wherein actuation of the shape memory alloy wires (16, 16′) causes a fluid-tight reservoir (17″) to e compressed by a lid (18) so as to reduce its volume from a maximum volume Vo to a minimum volume V1, this reduction resulting in a pressure increase that causes the opening of an outlet flap (13″) and the dispensing of a fluid through an outlet channel (13).
