Abstract
La disposizione di chiusura a tenuta fra gli alberi e la parete (5) della cassa di una mescolatrice ed impastatrice è eseguita per chiudere il foro passante con una boccola (12) della cassa, laddove un anello (13) a premistoppa, scorrevole longitudinalmente-assialmente, per l'accostamento a pressione con vincolo geometrico contro un appoggio (34), disposta fra il perno d'albero (6, 7) dell'attrezzo mescolatore (2, 2') e la boccola della cassa, è sollecitato con un accumulatore di energia meccanica. Durante il funzionamento di mescolamento per ottenere un uniforme funzione di tenuta della disposizione di chiusura a tenuta, la boccola (12) della cassa è formata da una boccola di alloggiamento (15), inserita nel foro passante, e da una boccola di base (14) che è associata concentricamente a questa, è accoppiata con la parete (15) della cassa ed è scorrevole longitudinalmente-assialmente in antagonismo ad un ulteriore immagazzinatore di energia meccanica ed inoltre insieme alla boccola di alloggiamento (15) racchiude uno spazio anulare (16), chiuso mediante anelli di tenuta elastici e sollecitabile mediante un fluido in pressione, laddove un ulteriore spazio anulare, delimitato longitudinalmente-assialmente fra l'appoggio (34) della boccola di base (14) e l'anello premistoppa (13), nonché delimitato radialmente fra la boccola di base (14) ed i perni di albero (6, 7), sono disposti in successione anelli di tenuta elastici (36, 42) (Figura 2).
