Abstract

Ventilantrieb einer Brennkraftmaschine mit untenliegender Nockenwelle und mindestens einem im Zylinderkopf gelagerten Kipphebel dessen Steg eine Ausformung mit einer zylindrischen Lagerfläche aufweist, welche seitlich geführt ist. Erfin­ dungsgemäß ist vorgesehen, daß die Lagerfläche für den U-för­ mig ausgebildeten Kipphebel (2) als halbzylindrischer Sattel (12) ausgebildet und ein integrierter Bestandteil eines am Zylinderkopf befestigbaren Zylinderkopfoberteils (3) ist, sowie daß der Schenkel (13) des Kipphebels (2) seitlich von Führungsflächen (14) des Zylinderkopfoberteils (3) geführt ist. Dadurch wird bei einfacher Konstruktion ein Antrieb er­ reicht, bei dem mit einem Minimum an Nacharbeit und Einzel­ teilen das Auslangen gefunden wird. Valve drive of an internal combustion engine with an underlying Camshaft and at least one in the cylinder head Rocker arm whose web is shaped with a cylindrical Has storage area, which is guided laterally. Erfin According to the invention, it is provided that the bearing surface for the U-för mig trained rocker arm (2) as a semi-cylindrical saddle (12) trained and an integrated part of an am Cylinder head attachable cylinder head upper part (3), and that the leg (13) of the rocker arm (2) laterally from Guide surfaces (14) of the cylinder head upper part (3) is. This makes it a drive with a simple design is enough, with a minimum of rework and individual share the sufficiency is found.
