A valve rotating mechanism for exhaust valves, especially of marine diesel engines, which mechanism is braced in a valve housing for the valve stem () between an upper and a lower drive element, is linked to the lower drive element via a freewheel device, which transmits rotation of the valve stem () during closing movement thereof, and is also braced relative to the upper drive element via a rotary cylinder (), which brings about rotation of the valve stem () through engagement with a fixed support cylinder (). Therein the rotary cylinder () and support cylinder () are engaged with one another via a helical gearing, wherein the rotary cylinder () is linked to the valve stem () via the freewheel device and the support cylinder () is fastened on the housing side.
