Abstract
يتعلق الاختراع الحالي بسدادات مانعة للتسريب seals للآلات التوربينية متعددة المراحل multistage turbomachines و، بالأخص، لبنية مضادة للدوران anti-rotation structure لسدادة مانعة للتسريب seal مزودة بين الأقراص المترابطة في آلة توربينية متعددة المراحل multistage turbomachine. وفي الاختراع الحالي، يتم توفير رباط مانع التسرب sealing band في شقوق تلقي receiving slots رباط مانع التسرب sealing band مقابلة لأقراص توربينية turbine disks مجاورة لإحكام غلق فجوة حلقية annular gap بينها. يتم تحديد ثقب نافذ through hole في أحد الأقراص، حيث يحدد الثقب النافذ محور ثقب طولي ويمتد إلى شق تلقي receiving slot الرباط المانع للتسرب sealing band في القرص. يتم تحديد سمة تعشيقة واحدة على الأقل على القرص ويمتد بشكل جانبي للثقب النافذ، متعامد على محور الثقب الطولي. يمتد عضو مسماري pin member من خلال الثقب ويتم وضعه داخل شق تلقي الرباط المانع للتسرب يمر من خلال فتحة في الرباط المانع للتسرب لمقاومة حركة الرباط المانع للتسرب نسبة إلى القرص. يتضمن العضو المسماري سمة مآزرة تمتد
