Abstract

νεμιστήρ του τύπου με έλικα μεταβλητού βήματος ιδιαιτέρως δια οικιακήν χρήσιν, του τύπου καθ' ον ταπτερύγια της έλικος είναι συναρμολογημένα ώστε ναπεριστρέφωνται επί γόμφων αισθητώς καθέτων προς τον άξονα περιστροφής του ανεμιστήρος, εδραζομένωνεντός εδράνων προβλεπομένων εντός του ομφαλού μεταδόσεως περιστροφικής κινήσεως εις την έλικα οι εν λόγω γόμφοι συνδέονται με πλήκτρα ή παρόμοια τα οποία ευρίσκονται εν γωνιακή αποκλίσει, εν σχέσει με τον άξονα περιστροφής των γόμφων τα εν λόγω πλήκτρα καθοδηγούνται κατά διαμήκη μετατόπισίν των παραλλήλως προς τον άξονα περιστροφής του ανεμιστήρος, δια μέσου τεμαχίου χειρισμού το οποίον καθορίζει την θέσιν των, που παρουσιάζει δακτυλιοειδή μορφήν και ολισθαίνει με κάποιον διάκενον, επί του άξονοςμεταδόσεως περιστροφικής κινήσεως εις τον ανεμιστήρα. Ο ανεμιστήρ χαρακτηρίζεται εκ του ότι περιλαμβάνει δύο δακτυλιοειδή τεμάχια (14,19) τοποθετημένα πέριξ του άξονος περιστροφής της έλικος, ο οποίος περιστρέφεται ελευθέρως εντός των ειρημένων δακτυλιοειδών τεμαχίων, των εν λόγω δακτυλιοειδών τεμαχίων όντων διατεθειμένων και συμπιεζομένων μεταξύτου ειρημένου τεμαχίου καθοδηγήσεως (11) της αλλαγής του βήματος της έλικος και του σταθερού φέροντος περιβλήματος (20) του ανεμιστήρος, των εν λόγω δακτυλιοειδών τεμαχίων σχηματιζόντων μεταξύ των μίαν τουλάχιστον κεκλιμένην επιφάνειαν (18) και όντων εις θέσιν να καθοδηγούνται κατά την σχετικήν περιστροφήν των πέριξ του άξονος Χ' - Χ περιστροφής της έλικος δια βραχίονος χειρισμού (17) ή αναλόγου,συνδεομένου με το εν τουλάχιστον εκ των δύο δακτυλιοειδών τεμαχίων (14,19). fan of the type with a variable pitch propeller especially for domestic use, of the type in which the vanes of the propeller are assembled to rotate on pegs substantially perpendicular to the axis of rotation of the fan, mounted in bearings provided within the umbilical for transmitting rotary motion to the propeller pegs are connected to keys or the like which are at an angular deviation, in relation to the axis of rotation of the pegs, said keys are guided by their longitudinal displacement parallel to the axis of rotation of the fan, by means of a control piece which determines their position, which it has an annular shape and slides with some gap, on the shaft transmission of rotary motion to the fan. The fan is characterized in that it comprises two annular pieces (14,19) placed around the axis of rotation of the propeller, which rotates freely within the separate annular pieces, said annular pieces being arranged and compressed between the separated guide piece (11) of the of changing the pitch of the helix and the fixed bearing housing (20) of the fan, said annular pieces forming between them at least one inclined surface (18) and being in a position to be guided during the relative rotation of the X' - X axis of rotation of the helix by a control arm (17) or similar, connected to at least one of the two annular pieces (14,19).
