Abstract

Το συγκρότημα στεγανότητος περιλαμβάνει ένα δακτύλιο στηρίξεως 3 στερεωμένο επί μιας αράκτου 1, ένα δακτυλιοειδές ωστήριο μέλος 7 συγκρατούμενο σφικτά σε επαφή με τον δακτύλιο στηρίξεως 3 δια μέσου ενός ελαστικού μέλους 10, και μέσα 13, 14 κατάλληλα για να μανδαλώνουν το δακτυλιοειδές ωστήριο μέλος 7 ώστε να εμποδιζουν την περιστροφή του ως προς το περίβλημα 2. Μεταξύ του περιβλήματος 2 και του δακτυλιοειδούς ωστηρίου μέλους 7 εγκαθίσταται ένας δακτύλιος στεγανότητας 20 που έχει μορφή σχήματος U κατά ακτινική τομή. Ο πρώτος κλάδος 20α του δακτυλίου τούτου σφραγίσεως 20 τίθεται και στερεώνεται σε μία κυκλική εκβάθυνση 16 προβλεπόμενη στο περίβλημα 2, ενώ ο δεύτερος κλάδος 20β τίθεται σε μία κυκλική εκβάθυνση 15 προβλεπόμενη στο δακτυλιοειδές ωστήριο μέλος 7, έχει το οπίσθιο τμήμα του συνδεδεμένο εκεί, και συγκρατείται αμέσως ή δια μέσου του πρώτου κλάδου 20α σε επαφή με το περίβλημα 2 έτσι ώστε να είναι ικανός να κινείται εκεί όταν υφίσταται την δύναμη την παραγόμενη από το ελαστικό μέλος 10. ωThe sealing assembly comprises a support ring 3 fixed on a stem 1, an annular thrust member 7 held tightly in contact with the support ring 3 by means of an elastic member 10, and means 13, 14 suitable for locking the annular thrust member 7 so that prevent its rotation with respect to the housing 2. Between the housing 2 and the annular thrust member 7 a sealing ring 20 is installed which has a U-shaped shape in radial section. The first branch 20a of this sealing ring 20 is placed and fixed in a circular recess 16 provided in the casing 2, while the second branch 20b is placed in a circular recess 15 provided in the annular thrust member 7, has its rear part connected there, and is held immediately or through the first branch 20a in contact with the housing 2 so that it is able to move there when it is subjected to the force produced by the elastic member 10. o
