KLAPPENVORRICHTUNG FÜR EINE VERBRENNUNGSKRAFTMASCHINE

FLAP DEVICE FOR AN INTERNAL COMBUSTION ENGINE
(FR)
SYSTÈME À CLAPET POUR MOTEUR À COMBUSTION INTERNE
Abstract:
(DE)
Es sind Klappenvorrichtung für Verbrennungskraftmaschinen mit einem Strömungsgehäuse (10), in dem ein erster Strömungskanal (12) ausgebildet ist, einer Stellwelle (16), einer ersten Klappe (18), die auf der Stellwelle (16) im ersten Strömungskanal (12) angeordnet ist, einer ersten Bohrung (30) im Strömungsgehäuse (10), durch welche ein erstes Ende der Stellwelle (16) nach außen ragt, einer ersten Lagerbuchse (24), in der die Stellwelle (16) gelagert ist und welche in der ersten Bohrung (30) angeordnet ist und Dichtmitteln (38), welche die Stellwelle (16) radial umgeben und zumindest ein erstes Federelement (40) aufweisen, bekannt. Um eine ausreichende Dichtigkeit auch bei auftretenden Wärmedehnungen sicher zu stellen, wird vorgeschlagen, dass das Federelement (40) vorgespannt gegen eine die Stellwelle (16) radial umgebende, zumindest axial bewegliche Anlaufscheibe (44), anliegt, deren axial entgegengesetzte Seite gegen die Klappe (18) anliegt.
(EN)
Flap devices for internal combustion engines are known, having a flow housing (10), in which a first flow channel (12) is formed, an actuating shaft (16), a first flap (18) arranged on the actuating shaft (16) in the first flow channel (12), a first bore (30) in the flow housing (10), through which a first end of the actuating shaft (16) protrudes to the outside, a first bearing bush (24), in which the actuating shaft (16) is mounted and in which the first bore (30) is arranged, and sealing means (38) that radially surround the actuating shaft (16) and are provided with at least one first spring element (40). In order to ensure a sufficient tightness, even in the event of thermal expansions, the spring element (40) according to the invention is biased against a thrust washer (44) that surrounds the actuating shaft (16) radially and can be moved at least axially, the axially opposite side of which rests against the flap (18).
(FR)
L'invention concerne un système à clapet, destiné à un moteur à combustion interne, qui comprend un boîtier d'écoulement (10) dans lequel est formé un premier conduit d'écoulement (12), un arbre de réglage (16), un premier clapet (18) qui est disposé sur l'arbre de réglage (16) dans le premier conduit d'écoulement (12), un premier trou (30) dans le boîtier d'écoulement (10) à travers lequel une première extrémité de l'arbre de réglage (16) dépasse vers l'extérieur, un premier coussinet (24) dans lequel est monté l'arbre de réglage (16) et qui est disposé dans le premier trou (30), et des moyens d'étanchéité (38) qui entourent l'arbre de réglage (16) dans le sens radial et possèdent au moins un premier élément à ressort (40). Selon l'invention, pour garantir une étanchéité suffisante même lorsqu'il se produit des dilatations thermiques, l'élément à ressort (40) repose avec une précontrainte contre une rondelle de butée (44) qui entoure l'arbre de réglage dans le sens radial, qui est mobile au moins dans le sens axial et dont le côté axialement opposé repose contre le clapet (18).
