摘要 |
A swing cam to actuate engine valves is rotatably disposed about a drive shaft. A first eccentric cam is tightly disposed on the drive shaft. A ring-link is rotatably disposed on the first eccentric cam. A second eccentric cam is tightly disposed on a control shaft which rotates to a given angular position in accordance with an operation condition of an associated internal combustion engine. A rocker arm is rotatably disposed on the second eccentric cam. A rod-link extends between the rocker arm and the swing cam. A first connecting pin pivotally connects a first arm portion of the rocker arm with the ring-link. A second connecting pin pivotally connects a second arm portion of the rocker arm with an end of the rod-link. A third connecting pin pivotally connects the other end of the rod-link with the swing cam. The first connecting pin is fixed to either one of the first arm portion of the rocker arm and the ring-link.
