Patent

CA 2086554

A rotary disc pump (10) comprises an outer housing (12) with an inner cylindrical rotor chamber (14) having an inlet (18) at one end and an outlet (20) at its outer periphery. A rotor assembly in the chamber comprises at least two parallel spaced discs (22,24) disposed co-axially in the chamber and connected together for rotation about their center axis. The inner opposing faces of the discs are spaced a predetermined distance apart, and a series of raised ribs or vanes (34, 35) are provided on at least one of the opposing faces, with the vane height being less than the disc spacing to leave a clearance between the opposing disc surfaces.

Pompe à disques rotatifs (10) comportant un carter (12) avec une chambre intérieure de rotor cylindrique (14) possédant une entrée (18) à une extrémité et une sortie (20) à sa périphérie extérieure. Un ensemble rotor monté dans la chambre comprend au moins deux disques (22, 24) espacés, parallèles, disposés coaxialement dans la chambre et reliés l'un à l'autre de façon qu'ils puissent tourner autour de leur axe central. Les faces opposées intérieures des disques sont séparées par un espace prédéterminé, et une série de nervures ou de palettes (34, 35) faisant saillie sont placées sur au moins une des faces opposées, la hauteur d'une palette étant inférieure à l'écartement entre les disques afin de laisser un espace libre entre les surfaces de disques opposées.
