バルブタイミング機構。Two different cam profiles for one on-off valve 9
A cam piece 19 having two drive cams 19a and 19b is attached to the cam shaft 31 so as to be movable in the axial direction, and by moving the cam piece 19 in the axial direction, the two drive cams are selectively switched to open and close. In a variable valve timing mechanism for an internal combustion engine that operates a valve, an air cylinder 41 is arranged parallel to the camshaft, and a fork 47 for moving the cam piece 19 is connected to the air cylinder 41.
A variable valve timing mechanism characterized in that it is coupled to a piston 43.45.
