Abstract
PURPOSE:To make the change of the valve opening time corresponding to the engine rotating speed possible by the operation of the relief valve mounted on the oil exhaust port and the spool provided in the spool oil pressure chamber. CONSTITUTION:The cam 1a is formed around the cam shaft 1 and the cylindrical lifter body 5 is slidably fitted in the cylinder bore 4. The bottom surface of the lifter body 5 touches the cam 1a, and the cylindrical plunger 6 is slidably fitted in the lifter body 5. The oil feeding port 13 which is constantly conneced with the oil feeding groove 12 and the triangular slit 15 which connects the oil feeding chamber 14 and the break chamber 10 are formed around the plunger 6, and the opening area is controlled by the frange part 9 of the housing 3.
