摘要： The rotary motion of a camshaft is transmitted from a first drive cam to a slide surface of a swing cam arm via intermediate members so that the swing cam arm lifts a valve. In this instance, the operating characteristic of the valve changes when the rotation position of a control shaft changes to change the positions of the intermediate members on the slide surface. When the operating characteristic control mode for the valve is to be changed from variable control to fixed control, coupling means couples the swing cam arm and input arm, thereby causing a second drive cam to swing the swing cam arm. The setting for the lift amount of the valve that is obtained when the second drive cam swings the swing cam arm is not smaller than a maximum lift amount setting for a situation where the first drive cam swings the swing cam arm.

摘要： Disclosed is a valve mechanism for an internal combustion engine that uses a motor to open/close a valve body of each cylinder. The valve mechanism includes a camshaft that is rotated by the motor and equipped with cams for driving the valve body of a plurality of cylinders; control means that drives the motor while making a mode switch between a normal rotation drive mode in which the camshaft is continuously rotated in one direction to drive the valve body and a swing drive mode in which the camshaft is swung to drive the valve body; and change means that changes the relative angular positions of cylinder-specific cams on the camshaft.

摘要： The present invention includes a rocker arm 16, which has an arm roller 18 at the center, a lash adjuster 30 for supporting a fulcrum P of the rocker arm 16, an oscillation arm 20, which has an oscillation cam surface (a non-pushing section 24 and a pushing section 26) that is in contact with the arm roller 18, and an adjustment mechanism for changing the reference arm rotation angle of the oscillation arm 20 in relation to the rocker arm 16 with a view toward changing the operating angle and lift amount of a valve disc 12 within a predetermined adjustment range. The adjustment mechanism includes a control shaft 22, a roller contact surface 32, a control arm 34, and an oscillation roller arm 38. The lash adjuster 30 is positioned so that its expansion/contraction direction is substantially parallel to a virtual straight line joining the rotation center Q of the oscillation arm 20 to the rotation center S of the arm roller 18.
