Abstract

Σιγαστήρας εξατμίσεως και μέθοδος κατασκευής αυτού. Ο σωλήν εξατμίσεως περιλαμβάνει εσωτερικόν σωλήνα, διαπεραστόν από τα αέρια κατά ακτινοειδή κατεύθυνσιν, που προβλέπεται μετά περιβλήματος (4) και πιθανώς υλικό καταπνίξεως του θορύβου (3), ως το ορυκτό μαλλί του περιβλήματος. Ο σωλήν (2) παράγεται δια της χρησιμοποιήσεως προκατασκευασμένων διατρήτων, γενικώς κυλινδρικών δακτυλίων λωριδωτού υλικού, των εν λόγω δακτυλίων θεωρουμένων κατά την αξονικήν τομήν εχόντων εξωτερικώς κοίλην διατομήν (5) με σκέλη διατομής (6,7) διαφόρων μηκών. Οι δακτύλιοι (10) τοποθετούνται αξονικώς παραπλεύρως αλλήλως και ευκάμπτως συνδέονται μεταξύ των δια του έχοντος μεγαλύτερο μήκος περιαυχενίου (6) ενός δακτυλίου (10) ανατρεπομένου επί του βραχυτέρου περιαυχενίου (6) επί του παρακειμένου δακτυλίου (10) προς διαμόρφωσιν συνδέσμου (Ι) τύπου σφαιρικού συνδέσμου. Ο σωλήν (2) δύναται ταχέως και ορθολογιστικώς να κατασκευάζεται με αυτόματο μηχανικό συγκρότημα συμφώνως προς το επιθυμητό μήκος και δύναται να κάμπτεται συμφώνως προς το επιθυμητό σχήμα άνευ μεταβολής αξιοσημειώτως του αξονικού μήκους του σωλήνος. ωExhaust muffler and method of its construction. The exhaust pipe comprises an inner tube, permeable to the gases in the radial direction provided by the housing (4) and possibly noise suppression material (3), as the mineral wool of the housing. The tube (2) is produced by the use of prefabricated perforations, generally cylindrical strips of strip material, said rings being considered in the axial section having externally concave cross-sections (5) with cross-sections (6,7) of various lengths. The rings (10) are axially positioned side by side and flexibly connected to each other by having a longer neck (6) of a ring (10) tipping over the shorter neck (6) on the adjacent ring (10) to form a coupling type (I) spherical link. The tube (2) can be quickly and rationally made with an automatic mechanical assembly according to the desired length and can be bent according to the desired shape without significantly changing the axial length of the tube. ω
