Abstract

PURPOSE:To reduce the weight of a gear train and thereby promote practically application of the gear train as moving valve mechanism by giving different widths to the gears to drive the moving valve cam shaft and the crank shaft interlocked. CONSTITUTION:The moving valve cam shafts 5.6 to open the valve elements of the suction valve 3 and exhaust valve 2 are connected to the crank shaft 13 through a gear train. Widths of the gears 11.12 to compose the gear train shall be so formed that the parts to be in engagement, at least, in the initial period of valve opening are wide and the rest are narrow.
