Abstract
In an arrangement for mounting a cam shaft and associated valve control elements on an internal combustion engine which has a cylinder head with intake and exhaust valves operated by an overhead cam shaft via rocker arms, the camshaft is supported on a cam shaft housing having spaced bearing blocks rotatably supporting the cam shaft and girders extend between the bearing blocks and have longitudinally extending bores receiving rocker arm support shafts and the girders have recesses wherein rocker arms are pivotally supported on the rocker arm support shaft extending through the recesses. The arrangement requires little mounting space on the cylinder head and the cam shaft housing can be mounted, preassembled with cam shaft and rocker arms, on the cylinder head.
