Abstract

Ein Betätigungshebel für Gaswechselventile von Brenn­ kraftmaschinen weist an seinem ventilschaftseitigen Hebelen­ de (5) eine Ventilspiel-Einstellvorrichtung auf, die aus einem das Hebelende (5) quer zur Hebelschwingebene durchdrin­ genden Schraubenbolzen (10) mit einer Mutter (11) und einem festklemmbaren Einstellelement (Ringscheibe 6) besteht. Der Schraubenbolzen (10), das Einstellelement (Ringscheibe 6) und das Hebelende (5) sind derart gegenseitig geführt und ab­ gestützt, daß beim Drehen des Schraubenbolzens (10) eine Relativbewegung zwischen Einstellelement (Ringscheibe 6) und Hebelende (5) entsteht, die im wesentlichen in Achsrich­ tung des Ventilschaftendes (9) liegt. An operating lever for Brenn gas exchange valves engines has on its valve stem side levers de (5) a valve lash adjuster, which consists of a through the lever end (5) transversely to the lever swing plane ing bolts (10) with a nut (11) and one clampable adjusting element (washer 6). The Screw bolt (10), the setting element (ring washer 6) and the lever end (5) are mutually guided and down supported that when turning the bolt (10) Relative movement between adjusting element (washer 6) and lever end (5) arises, which is essentially in the direction of the axis tion of the valve stem end (9).
