Abstract
1. Регулируемая система привода клапанов двигателя внутреннего сгорания, содержащая ! головку цилиндров, имеющую впускной или выпускной клапан, ! распределительный вал, установленный с возможностью вращения на головке цилиндров, ! тело кулачка, установленное с возможностью вращения вокруг внешней периферийной поверхности распределительного вала, причем тело кулачка включает в себя выступ кулачка, имеющий внешнюю периферийную поверхность для привода клапанов, и бобышку, выступающую радиально наружу из концевого участка тела кулачка, и ! механизм изменения периода открывания клапанов, установленный на распределительном валу и включающий в себя промежуточный вращающийся элемент, имеющий центр вращения, смещенный от оси распределительного вала, причем механизм изменения периода открывания клапанов выполнен с возможностью передачи вращения распределительного вала на бобышку тела кулачка посредством промежуточного вращающегося элемента, а также обеспечения изменения периода открывания клапана посредством регулирования угла фазы эксцентриситета промежуточного вращающегося элемента, ! при этом, по меньшей мере, часть бобышки расположена таким образом, что перекрывается с профилем носа выступа кулачка, если смотреть в осевом направлении тела кулачка. ! 2. Система по п.1, в которой бобышка расположена так, что находится внутри профиля носа выступа кулачка, если смотреть в осевом направлении тела кулачка. 1. Adjustable valve drive system of an internal combustion engine containing ! cylinder head with intake or exhaust valve, ! camshaft rotatably mounted on the cylinder head ! a cam body rotatably mounted around an outer circumferential surface of the camshaft, the cam body including a cam protrusion having an outer circumferential surface for valve actuation and a boss protruding radially outward from an end portion of the cam body, and ! a mechanism for changing the valve opening period mounted on the camshaft and including an intermediate rotating element having a center of rotation offset from the axis of the camshaft, and the mechanism for changing the valve opening period is configured to transfer the rotation of the camshaft to the cam body boss by means of an intermediate rotating element, as well as providing a change in the opening period of the valve by adjusting the phase angle of the eccentricity of the intermediate rotating element, ! wherein at least a portion of the boss is located such that it overlaps with the nose profile of the lobe of the cam when viewed in the axial direction of the cam body. ! 2. The system of claim 1, wherein the boss is positioned within the nose profile of the lobe of the cam as viewed in the axial direction of the cam body.
