Title (EN) IMPROVED ROTARY CENTRIFUGE SEAL
(FR) JOINT CENTRIFUGE ROTATIF AMELIORE
Abstract: front page image
(EN)An improved rotary centrifuge seal is disclosed of the type formed from a rotatable ring member (40) and a non-rotatable ring member (42) having a sealing face of each in contact to provide a dynamic seal between rotatable and stationary centrifuge elements. This improved seal is provided with means for entrapping solid particulate matter generated at areas of contact (44) and means for directing entrapped particles back to the area of contact where they are ingested. This prevents contamination of fluid being processed in the centrifuge with such solid particles, which is particularly important in blood-processing centrifuges.
(FR)Un joint centrifuge rotatif ameliore du type forme par un anneau rotatif (40) et un anneau non rotatif (42) ayant chacun une face d"etancheite en contact pour obtenir un joint d"etancheite dynamique entre les elements de centrifugation rotatifs et stationnaires. Ce joint ameliore est pourvu de moyens pour pieger des particules solides produites au niveau des zones de contact (44) et de moyens pour envoyer ces particules vers la zone de contact ou elles sont assimilees. Ceci evite la contamination du fluide traite dans la centrifugeuse avec de telles particules solides, ce qui revet une importance toute particuliere dans les centrifugeuses de traitement du sang.
