FIELD: engines and pumps. ^ SUBSTANCE: valve drive system incorporating a rocking lever with its one part designed to rest against the cam, the said lever first end being linked to the engine valve gear, a link mechanism incorporating the first and second linking levers. The first linking lever has a linking site arranged to run on the rocking lever and a support section on the second end. The second linking lever has the second linking site linked with a rocking lever and a moving site to be fitted onto the moving shaft. The system incorporates appliances to ensure shaft displacement. The first and second linking sites are arranged in parallel and linked to allow a relative running on the rocking lever, while the second linking lever support site is arranged closer to the engine valve than the first linking lever support site. ^ EFFECT: smaller sizes of the valve drive, chances of continuous variation of the valve up travel with reliability and life of the drive intact. ^ 12 cl, 21 dwg |
