Abstract
A valve operating system in an internal combustion engine comprises an operating-force generating means for generating an operating force corresponding to the revolution of the engine, an operating-force applying means for operating an engine valve, a hydraulic transmitting means capable of hydraulically transmitting the operating force between the operating-force generating means and the operating-force applying means, a mechanical transmitting means capable of rigidly transmitting the operating force between the operating-force generating means and the operating-force applying means, and a selective switchover means capable of alternatively switching-over the transmissions of the operating force from the operating-force generating means to the operating-force applying means by the hydraulic transmitting means and by the mechanical transmitting means. Thus, it is possible to select either the transmission of the operating force by the hydraulic transmitting means or the transmission of the operating force by the mechanical transmitting means to insure a reliable operation of the engine valve.
