<p>PROBLEM TO BE SOLVED: To simplify a constitution as a whole unit of an internal combustion engine ant to decrease a number of part items. SOLUTION: In the periphery of an intake/exhaust side drive shaft 1, 2 synchronously rotated with an engine, a cylindrical cam shaft 11 divided in each cylinder is arranged, and, in accordance with an eccentric position of annular disks 13, 14, a cam shaft 3 is rotated at an unequal speed. Both the annular disk 13 in an intake side and the annular disk 14 in an exhaust side are rotatably held by the same control housing 20. By an eccentric bush 26 and an eccentric cam 25, the control housing 20 is supported, when a control shaft 23 provided with the eccentric cam 25 is rotated, the control housing 20 is socked and both the annular disks 13, 14 are simultaneously eccentrically operated.</p> |
