Title
(DE) VENTIL EINER BRENNKRAFTMASCHINE
(EN) VALVE OF AN INTERNAL COMBUSTION ENGINE
(FR) SOUPAPE D'UN MOTEUR À COMBUSTION INTERNE
Abstract
(DE)
Die Erfindung betrifft ein Ventil (2) einer Brennkraftmaschine (1), insbesondere ein Einlassventil oder ein Auslassventil, mit einem Ventilteller (3), der über eine Ventilkehle (4) in einen Ventilschaft (5) übergeht. Erfindungswesentlich ist dabei, - dass der Ventilschaft (5) einen Durchmesser d ≤ 6mm hat, - dass der Ventilschaft (5) an seinem dem Ventilteller (3) abgewandten Ende eine erste Fase (6) aufweist, - dass der Ventilschaft (5) zumindest eine Umfangsnut (7) aufweist, wobei an einem Übergang des Ventilschaftes (5) zur Umfangsnut (7) eine zur ersten Fase (6) gleichgerichtete zweite Fase (8) angeordnet ist, oder dass der Ventilschaft (5) zumindest eine Umfangsnut (7) aufweist und wobei an einem Übergang des Ventilschaftes (5) zur Umfangsnut (7) ein zur ersten Fase (6) gleichgerichteter und gerundeter, erster Abschnitt (17) angeordnet ist. Hierdurch kann insbesondere die Montage des Ventils (2) erleichtert werden.
(EN)
The invention relates to a valve (2) of an internal combustion engine (1), in particular an inlet valve or an outlet valve, comprising a valve disc (3) that transitions into a valve shaft (5) via a valve throat (4). According to the invention: the valve shaft (5) has a diameter d ≤ 6mm; the valve shaft (5) has a first chamfer (6) at the end thereof facing away from the valve disc (3); the valve shaft (5) has at least one circumferential groove (7), wherein a second chamfer (8) is arranged in alignment with the first chamfer (6) at a transition of the valve shaft (5) to the circumferential groove (7); or the valve shaft (5) has at least one circumferential groove (7) and wherein a first section (17) that is rounded and aligned with the first chamfer (6) is arranged at a transition of the valve shaft (5) to the circumferential groove (7). In this way, in particular the assembly of the valve (2) can be facilitated.
(FR)
L'invention concerne une soupape (2) d'un moteur à combustion interne (1), en particulier une soupape d'admission ou une soupape de sortie, pourvue d'une tête de soupape (3), qui devient une tige de soupape (5) en passant par une gorge de soupape (4). Selon l'invention, il est essentiel que : - la tige de soupape (5) présente un diamètre d ≤ 6 mm ; - la tige de soupape (5) comporte, sur son extrémité opposée à la tête de soupape (3), un premier chanfrein (6) ; la tige de soupape (5) comporte au moins une rainure périphérique (7), un deuxième chanfrein (8) orienté dans le même sens que le premier chanfrein (6) étant disposé sur une zone de transition de la tige de soupape (5) vers la rainure périphérique (7) ; ou la tige de soupape (5) comporte au moins une rainure périphérique (7), un premier tronçon (17) orienté dans le même sens que le premier chanfrein (6) et arrondi étant disposé au niveau d'une zone de transition de la tige de soupape (5) vers la rainure périphérique (7). Cela permet notamment de simplifier le montage de la soupape (2).
