Title
(DE) LUFTANSAUGVORRICHTUNG MIT VARIABLER SAUGROHRLÄNGE
(EN) AIR INTAKE DEVICE WITH INTAKE PIPES OF VARIABLE LENGTH
(FR) DISPOSITIF D'ADMISSION D'AIR AVEC PIPES D'ADMISSION DE LONGUEUR VARIABLE
Abstract
(DE)
Zwischen jeweils einem Bereich der Saugrohre (25) und einem Sammler (26) sind Einmündungsöffnungen (29) vorgesehen, die durch eine Verschlußeinrichtung (30) verschließbar sind. Die Verschlußeinrichtung ist außerhalb des Einflußbereichs der durch die Saugrohre strömenden Ansaugluft angeordnet, so daß auf die Verschlußeinrichtung dadurch keine Kraft ausgeübt wird, die diese verstellen könnte. Zur Verhinderung einer Abrißbildung der Ansaugluft sind Luftleitelemente (33) und Luftleitwandungen (32) vorgesehen. Anwendbar im Ansaugtrakt einer Brennkraftmaschine.
(EN)
Inlet apertures (29) are provided between a region of the intake pipes (25) and a collector (26); these apertures can be closed off by a closure unit (30) which is fitted outside the area of influence of the intake air flowing through the intake pipe, so that the intake air exerts no potentially disruptive force on the closure unit. In order to prevent the formation of separate currents in the intake air, duct elements (33) and air duct walls (32) are provided. The proposed system can be used in the intake tract of an internal combustion machine.
(FR)
Des ouvertures d'admission (29), pouvant être obturées par un dispositif d'obturation (30), sont placées entre une zone de chacune des pipes d'admission (25) et un collecteur (26). Le dispositif d'obturation est monté à l'extérieur de la zone d'influence de l'air admis à travers les pipes d'admission, de sorte que ce dispositif d'obturation n'est soumis à aucune force susceptible de le dérégler. Des éléments de conduction d'air (33) et des parois de conduction d'air (32) empêchent la division de l'air admis. Ce système peut être utilisé dans le conduit d'admission d'un moteur à combustion interne.
