Abstract (en)
[origin: EP2644854A1] [Problem to be Solved] To provide a variable valve train for an internal combustion engine which duty controls an electromagnetic solenoid for moving a connecting pin, thereby reducing power consumption of the electromagnetic solenoid and preventing generation of a hitting sound. [Solution] In a variable valve train for an internal combustion engine, control means (70) energizes an electromagnetic solenoid (60) to cause a moving core member (61, 62) to protrude, and thereby the connecting pin (56) to move against urging force of the spring (54) so that rocker arms (51, 52) are connected together and integrally rocked. The control means (70) duty controls the electromagnetic solenoid (60) and drives the moving core member (61, 62).
