Title (EN) SELF-ALIGNING DYNAMIC CLEARANCE SEALS AND FLUID-MOVING DEVICES UTILIZING SUCH SEALS
(FR) JOINTS À JEU DYNAMIQUE AUTO-ALIGNANTS ET DISPOSITIFS DE DÉPLACEMENT DE FLUIDE UTILISANT DE TELS JOINTS
Abstract: front page image
(EN)A self-aligning dynamic clearance seal assembly (20) is disclosed. The assembly comprises a stationary casing (23), a moving member (24), a housing member (26) circumferentially disposed between the stationary casing and the moving member, a sealing member (25) circumferentially disposed between the housing member and the moving member, and two elastomeric seals (21,22). The first elastomeric seal prevents the flow of a fluid into a gap between the sealing member and the. stationary casing. The second elastomeric seal, when compressed, prevents the housing member from biasing against the sealing member. The sealing member and the moving member define a continuous and uniform gap having a size that allows the fluid to fill the gap but prevents the fluid from flowing through the gap from the first side to the second side of the opening under an operating pressure differential between the first and the second side. A pump utilizing the self- aligning seal assembly is also provided.
(FR)L'invention concerne un ensemble de joint à jeu dynamique auto-alignant (20). L'ensemble comprend un carter fixe (23), un élément mobile (24), un élément de boîtier (26) disposé de manière circonférentielle entre le carter fixe et l'élément mobile, un élément d'étanchéification (25) disposé de manière circonférentielle entre l'élément de boîtier et l'élément mobile, et deux joints en élastomère (21, 22). Le premier joint en élastomère empêche l'écoulement d'un fluide dans un espace entre l'élément d'étanchéification et le carter fixe. Le second joint en élastomère, lorsqu'il est comprimé, empêche que l'élément de boîtier ne soit rappelé contre l'élément d'étanchéification. L'élément d'étanchéification et l'élément mobile définissent un espace continu et uniforme ayant une dimension qui permet au fluide de remplir l'espace mais empêche que le fluide ne s'écoule à travers l'espace depuis le premier côté vers le second côté de l'ouverture sous un différentiel de pression actif entre le premier et le second côté. Une pompe utilisant l'ensemble de joint auto-alignant est également fournie.
