Abstract: Un déplacement axial entre deux composants (10, 17) d'une vanne se produit à la suite d'une rotation relative par l'intermédiaire de la coopération de deux rampes hélicoïdales (29, 31). Une autre paire de rampes hélicoïdales (30, 38) est disposée concentrique par rapport à la première paire, mais avec un décalage angulaire de 180°, de sorte que, lorsque les deux composants (10, 17) présentent une séparation axiale maximum le contact résiduel entre les rampes de chaque paire (zones sombres de la Fig. 5e) se situe de part et d'autre de l'axe x de rotation et de prolongement, enpêchant ainsi tout mouvement basculant du composant (17) hors de son alignement axial par rapport au composant (10). Dans d'autres constructions, plus de deux paires de rampes sont utilisées. Dans le mode de réalisation illustré, les rampes de la présente invention remplacent un filetage de vis pour assurer le réglage de la charge d'un ressort de vanne et permettre l'utilisation de techniques de fabrication et d'assemblage plus économiques.

Date Dec. 27, 1990.Pumping takes place within the micro-pump as a result of the deformation of a plate (12) using a piezo-electric pad (13). The deformation produces a variation in volume within a pumping chamber (15) defined inside a plate (11) which is made of a material which can be machined using photolithographic processes. The pump outlet (3) is blocked off, selectively, by a membraned check-valve (18) which is in direct communication with another check-valve (16) via the pumping chamber. The check-valve (16) selectively enables the pumping chamber to communicate with the pump inlet (2). The outlet valve membrane (18) has a layer of oxide (17) providing a pretension on closing. The check-valve thus has a regulatory effect on the pump operation, making the flow almost independent of the outlet (3) pressure. Application: injection of exact doses of medication.
