Abstract

L'invention concerne des dispositifs de rattrapage du jeu axial et radial et un auto-fonctionnement permettant d'obtenir une amélioration des rendements volumétrique et mécanique de pompe volumétrique du type à piston oscillant.
Une pièce de compression radiale (3) plaque un piston (1) sur un corps (2). Une pièce de compression axiale (8) agit sur une plaque avant (10), munie d'un orifice d'équilibre des pres­ sions (11), qui appuie le piston (1) sur une plaque arrière (12). Le piston (1) possède une fente dans laquelle un élément élasti­ que permet un contact rigoureux du piston avec un diaphragme (19). Une glace tournante (27) appuie en permanence sur une contreface fixe (24) composant ainsi une garniture d'étan­ chéité
Les dispositifs selon l'invention sont particulièrement des­ tinées aux pompes volumétriques effectuant en chimie et para­ chimie des opérations de transfert basse et haute pression. Débit fixe ou variable. Mélange, broyage et filtration.
