  • Valve operating system in internal combustion engine
    Patent number: 5282443
    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.
