Abstract (en)

[origin: JP2017172587A] PROBLEM TO BE SOLVED: To disclose a configuration of a new valve train.SOLUTION: A valve train (1) for an internal combustion engine comprises a cam shaft (2); a cam follower (3); two first cams (4a, 4a) arranged to be spaced apart to each other in an axial direction at the cam shaft (2) so as to endure against torque and having the same first cam outer shapes (17a, 17b); and two second cams (4b, 4b) spaced apart to each other in an axial direction and arranged at the cam shaft (2) to have the same second cam outer shapes (17a, 17b) so as to endure against torque. The first and second cams (4a, 4b) are alternatively arranged in an axial direction at the cam shaft (2). The cam follower (3) can be adjusted in an axial direction between a first position where it is connected in driving to the first cam (4a) and a second position where it is connected in driving to the second cam (4b). The cam follower (3) has a mechanical adjustment device (7) cooperated with the cam shaft (2) so as to adjust the cam follower (3) in an axial direction between the first position and the second position.SELECTED DRAWING: Figure 1
