摘要： A valve system is provided for driving engine valves arranged in an internal combustion engine. The valve system comprises a valve drive arm member pivotally supported on a side of a main body of an engine while being maintained in contact with end portions of the engine valves, a first rocker arm for rocking the valve drive arm member, a second rocker arm for causing the valve drive arm member to undergo rocking at an amplitude greater than rocking by the first rocker arm, and coil springs for urging the engine valves in closing directions, respectively. Each coil spring is interposed between a retainer disposed fixedly on the corresponding engine valve and a cylinder head. Each coil spring is designed to avoid interference with a rocking path of the corresponding rocker arm on a side of the coil spring.

摘要： A variable valve mechanism using a non-uniform coupling in an internal combustion engine is equipped with an axis-supporting member for supporting a cam-side rotation axis in an eccentric state. In the variable valve mechanism, the axis-supporting member is driven while taking account of friction occurring in the axis-supporting member by changing the position of the axis-supporting member so as to align with the direction of a dragging torque generated between the axis-supporting member and an intermediate rotating member or between the axis-supporting member and a rotation axis member.
