摘要:
To provide a valve system for an engine, in which a valve stem for an engine valve is slidably fitted in a guide cylinder provided in a cylinder head. A rocker arm is interlocked to rock with rotation of a camshaft. The rocker arm is also interlocked with the valve stem. With the above construction, local wear, galling, and the like in the guide cylinder can be prevented. Accordingly, the reliability can be improved. A lifter is interposed between a rocker arm and a valve stem. The lifter is formed into a cylindrical shape with a closed bottom and has a diameter larger than an outside diameter of the valve stem. The lifter is fitted in a lifter housing in such a manner as to be slidable in the axial direction of the valve stem. The lifter housing is fixed to a cylinder head.
