Abstract

E' descritta una tenuta a nido d'ape associata cooperativamente con una paletta girevole di una turbina a vapore avente un cilindro, tenuta che comprende una piastra di sopporto, collegata in modo fisso ad una parte di montaggio del cilindro, la parte di montaggio avendo associato un canale di rimozione dell'umidità per assicurare una rimozione efficace ed efficiente dell'acqua raccolta nella tenuta a nido d'ape.
