Abstract

In una valvola rotativa è realizzabile una disposizione di tenuta soggetta a posa usura fra i dischi laterali della sua ruota cellulare e i rispettivi cappelli di supporto della sua carcassa, per il fatto che un anello di riempimento (7a) di materia plastica è disposto, flottante, fra ciascun cappello di supporto (5a) e il relativo disco laterale (4a), e viene caricato da opportuni mezzi elastici (8a) sia in direzione assiale che anche in direzione radiale.
