VARIABLE VALVE TRAIN

Title:

VARIABLE VALVE TRAIN

Document Type and Number:

Japanese Patent JP2010038002

Kind Code:

A

Abstract:

To provide a more compact variable valve train.

This valve train includes: a rotary cam 10 rotating together with a camshaft 11; an oscillating member 20 pivotally supported by the camshaft 11 in such a manner that the same can relatively rotate without rotating together with the camshaft 11; a power transmission mechanism 30 transmitting torque of the rotary cam 10 to the oscillating member 20; and a control mechanism 40 displacing the power transmission mechanism 30. The control mechanism 40 includes a control shaft 41 arranged coaxially with the camshaft 11 and extending in a longitudinal direction of the camshaft 11, and a control lever 46 pivotally attached on a control shaft 41 at one end and pivotally attached on the power transmission mechanism 30 at another end. The maximum lift L of valves 8, 8 driven by the oscillating member 20 is changed by rotating the control shaft 41 in a circumference direction of the camshaft 11.
