Abstract: A valve mechanism for an internal-combustion engine with at least two valves 1 per cylinder which can be actuated by cams 2, 7 of a camshaft 3 via rockers 4, 6. The rockers are mounted pivotally next to one another on a common fixed shaft 5, and they bear with sliding surfaces 8 against their cams. The rockers are pressed against one another by a spring 10, and their sliding surfaces 8 are aligned at least intermittently with one another and then form an essentially continuous surface. The camshaft 3 has a longitudinal channel 13 which is connected to a lubricant source and from which extends, for the lubrication of a plurality of sliding surfaces, a lubricating-oil bore 14 which opens out on the circumferential surface of a cam 7 cooperating with one of these sliding surfaces.
