Abstract

PURPOSE: To obtain a smooth valve lift, by moving oil into and out of a moving valve unit by the action of a free piston and braking the free piston.
CONSTITUTION: The free piston 26 and a second free piston 27 are in the uppermost position in such a state of slow running that the oil pressure in a first oil pressure chamber 31 is low. When a cam 25 rotates and a tapped body 22 starts lifting in that state, the oil pressure in a third oil pressure chamber 46 rises. As a result, the free piston 26 and the second free piston 27 move down together and the oil in a second oil pressure chamber 33 escapes through a connection hole 38 and is then absorbed by the motion of a piston 42. Therefore, if the second free piston 27 is in the uppermost position, this piston can move down sufficiently. Thereby, the lift of the tapped body 22 is completely absorbed and a plunger 45 can be kept stopped
