Abstract (en)
[origin: EP2322771A1] A variable valve operating system includes a circular eccentric portion (22) provided for a control shaft (17), an external gear formed on a cam follower (31) swingably supported on the eccentric shaft portion, and an internal gear formed on a rocking cam (23) so as to be engaged with the external gear. The external gear is revolved by the eccentric shaft portion (22) around the axis of the control shaft (17), an engaged portion of the internal gear with the external gear is moved in a circumferential direction of the internal gear by the revolution of the external gear, and the position of the rocking cam (23) with respect to the cam follower (31) is changed by the movement of the engaged portion of the internal gear.
