Abstract
PURPOSE: To control the timing of a valve moving system depending on the running condition of an engine and reduce the impact upon the valve moving system at the starting time of the valve lift due to a squeeze effect which is produced when a communication hole between a main oil pressure chamber and a control oil pressure chamber is shut off, by a simple construction.
CONSTITUTION: An oil pressure chamber is defined between a tappet body 6 which follows the motion of a cam 5 and a fixed wall 3 penetrated by a piston part 21a of a cap 21 whereon a push rod 20 is seated. The oil pressure chamber is divided into the main oil pressure chamber M consisting of a chamber A surrounded by the fixed wall 3 and a fixed cylinder 4 and a chamber B located between a free piston 16 and a plunger 10 and a communication hole 8 of a moving cylinder 7, and the control oil pressure chamber N surrounded by the tappet body 6 and the free pistons 15, 16. A communication passage 26 provided in the free piston 16 is shut off by the tappet body 6 in a prescribed lift position corresponding to the running condition of the engine to set the volume of the main oil pressure chamber M.
