Title
(DE) DREHSTELLER
(EN) ROTATING ACTUATOR
(FR) ACTIONNEUR ROTATIF
Abstract
(DE)
Bei einem Drehsteller treten insbesondere bei Verwendung von Saugrohren und Saugrohranschlüssen aus Kunststoff infolge von Wirbelbildungen Geräuschentwicklungen auf, die vermieden werden sollen. An der Drosselöffnung (13) sind hierzu ebene Begrenzungsflächen (25) und an der Austrittsöffnung (14) ist eine ebene Begrenzungsfläche (26) ausgebildet. Darüber hinaus sind im Eingangsstutzen strömmungsgünstige übergänge mit je einem konvexen und einem konkaven Bereich (40, 41) von einer kegelstumpfförmigen Verengung (24) zu den Begrenzungsflächen (25) und im Ausgangsstutzen (6) ist ein strömungsgünstiger Übergang mit einem konvexen und konkaven Bereich (42, 43) zur kegelstumpfförmigen Erweiterung (27) des Ausgangsstutzens (6) vorgesehen. Der Drehsteller wird insbesondere zur Regelung der Leerlaufdrehzahl von Brennkraftmaschinen verwendet.
(EN)
In a rotating actuator, especially with the use of plastic intake pipes and connections, noise is produced as a result of turbulence which should be prevented. To this end there are plane boundary surfaces (25) at the throttle aperture (13) and another (26) at the outlet aperture (14). In addition, there are in the intake stub flow-assisting transitions with a convex and a concave region (40, 41) of a truncated conical taper (24) towards the boundary surfaces (25) and in the outlet stub (6) there is a flow-assisting transition with a convex and concave region (42, 43) towards the truncated conical broadening (27) of the outlet stub (6). The rotating actuator is especially usefull to control the idling speed of internal combustion engines.
(FR)
Dans un actionneur rotatif, il se produit des bruits dûs aux tourbillonnements qui se forment notamment avec l'utilisation de tubulures d'aspiration et de raccords de tubulures d'aspiration en plastique, bruits qu'il convient d'éviter. A cet effet, des surfaces de délimination (25) planes sont formées au niveau de l'orifice d'étranglement (13) et une surface de délimitation (26) plane est formée au niveau de l'orifice de sortie (14). En outre, dans la tubulure d'entrée, il existe des passages favorisant l'écoulement, ayant chacun une zone convexe et une zone concave (40, 41) d'un étranglement (24) tronconique et allant vers les surfaces de délimitation (25). Dans la tubulure de sortie (6), un passage favorisant l'écoulement qui comporte une zone convexe et concave (42, 43) va vers l'évasement (27) tronconique de la tubulure de sortie (6). L'actionneur rotatif est utilisé, en particulier, pour réguler la vitesse à vide de moteurs à combustion interne.
