Abstract
Η παρούσα εφεύρεση σχετίζεται με μία μεμβράνη (12) για έναν θάλαμο πιέσεως (10) κατάλληλο για λειτουργία με έναν αισθητήρα πιέσεως (22). Η μεμβράνη περιλαμβάνει ένα ελαστικό κυκλικό τοίχωμα (120) κατάλληλο για το κλείσιμο της μίας πλευράς του θαλάμου πιέσεως (10) έτσι ώστε να προσδιορίζεται ένας διαχωρισμός μεταξύ του εσωτερικού του θαλάμου πιέσεως και του εξωτερικού χώρου, και ένα κυκλικό χείλος (124) κατάλληλο για να μπορεί να ενώνεται με το κυρίως σώμα (16) του θαλάμου πιέσεως. Η μεμβράνη χαρακτηρίζεται από το ότι το κυκλικό ελαστικό τοίχωμα αυτής, όταν δεν υπάρχει διαφορά μεταξύ των δύο διαφορετικών πιέσεων που επιδρούν αντίστοιχα επί της εσωτερικής επιφανείας (121) και επί της εξωτερικής επιφανείας (122), φέρει ένα κυρτό προς τα έξω σχήμα. Η παρούσα εφεύρεση σχετίζεται επίσης με έναν θάλαμο πιέσεως ο οποίος περιλαμβάνει αυτή τη μεμβράνη.
