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.

Mounting arrangement for a camshaft and associated valve control

The invention relates to a heating installation for the passenger compartment of omnibuses, comprising radiant heating elements which are disposed on the omnibus side walls under the side windows. In order to accommodate in a space-saving manner the hot-water carrying heating pipes supplying the radiant heating elements with thermal energy, the upper wall surface of the radiant heating elements which faces the passenger compartment is formed by a continuous interior cladding bearer of the respective omnibus side wall and the interior cladding bearer is formed in the armrest region of the passenger seats into a longitudinally continuous arm support. The heating pipe is laid in the cavity formed by this construction.
