Abstract

La macchina (1) comprende due ruote dentate (5 e 6) ingrananti fra loro, due boccole (13) supportanti mezzi (7 e 8) delle ruote (5 e 6), un corpo macchina (2) in cui sono installate le ruote (5 e 6) e le boccole (13), e due piastre (3 e 4) di chiusura del corpo macchina (2). Nelle piastre (3 e 4) è realizzata un a sede (26) per una guarnizione di tenuta (25) realizzata in pezzo unico e comprendente un primo elemento anulare (27) ed un secondo elemento anulare (28) interno al primo ed unito a questo per un lungo tratto tramite una parete sottile (34) la quale definisce due canali (35 e 36) lungo i quali è presente un fluido ad alta pressione. La guarnizione (25) delimita due intercapedini, una, per fluido a bassa pressione, racchiusa, dal secondo elemento (28), e la seconda, per fluido ad alta pressione, racchiusa fra i due elementi (27 e 28).
