A microsystem for converting pressure difference in fluid into mechanical displacement includes input and output nozzles, two interleaved parts, one of which is mobile part, between which the fluid flows. During displacement, the parts define an expanding fluid pocket that moves from the input nozzle to the output nozzle. The micro-system also includes top and bottom planes between which the mobile part is mounted for displacement relative to each plane, an overhanging distal portion along which the fluid flows, and a proximal portion mechanically linked to a plane via a link allowing only longitudinal translation of the proximal portion, and a reinforcement including a first side fastened to one of the planes and, a second side that is either fastened to or in sliding contact with the overhanging distal portion of the mobile part to limit its deformation in a transverse direction perpendicular to the longitudinal direction. |

1. An apparatus comprising a microsystem for converting a pressure difference in a flowing fluid into a mechanical displacement according to the principle of an expansion valve, wherein said microsystem comprises an input nozzle for receiving said fluid, said fluid being a compressed fluid at said input nozzle, an output nozzle for outputting said fluid, said fluid being an expanded fluid at said output nozzle, at least two parts, at least one of which is a mobile part, between which said fluid flows to pass from said input nozzle to said output nozzle by displacing said at least two parts relative to one another, said at least two parts being shaped and interleaved one inside the other so that, during displacement thereof, said at least two parts define at least one pocket of fluid that concurrently increases in volume and moves away from said input nozzle to then meet said output nozzle, a top plane and a bottom plane between which said mobile part is inserted, said top plane and said bottom plane containing between said at least two parts said fluid, said mobile part being mounted to be able to be displaced relative to each of said top and bottom planes, said mobile part comprising an overhanging distal portion along which said fluid flows, said overhanging distal portion forming a shaped portion of said mobile part, and a proximal portion mechanically linked to a selected plane via a link allowing only a translational displacement of said proximal portion in a longitudinal direction, wherein said selected plane is selected from the group consisting of said bottom plane and said top plane, and at least one reinforcement, said at least one reinforcement comprising a first side fastened to at least one of said top and bottom planes and, a second side that is at least one of fastened to and in sliding contact with said overhanging distal portion of said mobile part to limit deformation thereof in a transverse direction at right angles to said longitudinal direction. |
