Abstract

La guarnizione a spazzola deve chiudere a tenuta spazi sollecitati da pressione in misura differente. Le setole sono afferrate da un tubo di bloccaggio su un nucleo estendentesi sulla circonferenza, sporgono da una fessura longitudinale del tubo di bloccaggio e sono guidate, attraverso una fessura circonferenziale assiale, con azione di tenuta, contro il rotore. Le setole inoltre, per la maggior parte della loro estensione di lunghezza, sono disposte tra superfici di fessura parallele della fessura circonferenziale assiale. Inoltre le setole sono condotte nella fessura circonferenziale assiale con azione di tenuta su una rispettiva superficie della fessura e formano, rispetto alla rispettiva altra superficie di fessura, una fessura assiale. Una parte di parete rivolta verso loThe brush seal must seal tightly the spaces stressed by pressure to a different extent. The bristles are gripped by a locking tube on a core extending on the circumference, protrude from a longitudinal slot of the locking tube and are guided, through an axial circumferential slot, with sealing action, against the rotor. Furthermore, the bristles, for most of their length extension, are arranged between parallel slit surfaces of the axial circumferential slit. In addition, the bristles are driven into the circumferential axial slot with a sealing action on a respective surface of the slot and form, with respect to the respective other slot surface, an axial slot. A part of the wall facing it
