Title:
VARIABLE VALE LIFT DEVICE OF ENGINE
Document Type and Number:
Japanese Patent JP2019035396
Kind Code:
A
Abstract:
To provide a valve device capable of carrying out a pause control operation of a valve for deactivating a variable valve lift device and a cylinder.SOLUTION: A variable valve lift device of an engine, includes: a first body which rotates by rotations of a high-speed cam; a second body which rotates by rotations of the high-speed cam when coupled with the first body, and adjusts the lift amount of a valve by rotations of a low-speed cam when separated from the first body; a drive module makes a drive pin appear and disappear so as to couple or separate the first body and the second body; a rotary shaft provided across both side walls of the first body and the second body; and a return spring which provides restoration force for returning the first body to an original position. The drive module variably controls the lift amount of the valve in two stages of a high-speed mode and a low-speed mode, on the basis of an operation condition of an engine, and when only the high-speed cam is installed on a cam shaft, separates the first body and the second body to deactivate a cylinder, in a low-speed and low load state of the engine.SELECTED DRAWING: Figure 3
