Abstract
(DE)
Die Erfindung betrifft eine Ventildrehvorrichtung (24) für ein Ventil (10), vorzugsweise Einlass- oder Auslassventil, einer Brennkraftmaschine. Die Ventildrehvorrichtung (24) weist eine Ventilrückstellfeder (22) zum Vorspannen des Ventils (10) in einer Richtung zu einer Schließstellung des Ventils (10) und eine Tellerfeder (40), die in Wirkverbindung zwischen der Ventilrückstellfeder (22) und einer mit einem Schmierfluid geschmierten Abstützfläche (44) angeordnet ist, auf. An einem Umfang, vorzugsweise Innenumfang,der Tellerfeder (40) ist ein zumindest teilweise, vorzugsweise vollständig, umlaufender Kragenabschnitt (46) angeordnet. Der Kragenabschnitt (46) kann verschleißmindernd sein und/oder eine Montierbarkeit der Ventildrehvorrichtung (24) verbessern.
(EN)
The invention relates to a valve rotating device (24) for a valve (10), preferably an intake valve or exhaust valve, of an internal combustion engine. The valve rotating device (24) has a valve restoring spring (22) for preloading the valve (10) toward a closed position of the valve (10) and a Belleville spring (40), which is arranged in operative connection between the valve restoring spring (22) and a support surface (44), which is lubricated with a lubricating fluid. An at least partially, preferably completely, peripherally extending collar portion (46) is arranged on a periphery, preferably inner periphery, of the Belleville spring (40). The collar portion (46) can have a wear-reducing effect and/or can make the valve rotating device (24) easier to install.
(FR)
L'invention concerne un dispositif de rotation de soupape (24) pour une soupape (10), de préférence une soupape d'admission ou d'évacuation, d'un moteur à combustion interne. Le dispositif de rotation de soupape (24) comporte un ressort de rappel (22) de soupape servant à précontraindre la soupape (10) dans une direction par rapport à une position de fermeture de la soupape (10) et une rondelle-ressort (40), qui est disposée en interaction entre le ressort de rappel (22) de soupape et une surface d'appui (44) lubrifiée avec un fluide lubrifiant. Une section en porte-à-faux (46) au moins en partie, de préférence totalement, périphérique est disposée sur une périphérie, de préférence une périphérie interne, de la rondelle-ressort (40). La section en porte-à-faux (46) peut réduire l'usure et/ou faciliter un montage du dispositif de rotation de soupape (24).
