Title:
VARIABLE VALVE DEVICE
Document Type and Number:
WIPO Patent Application WO/2006/025566
Kind Code:
A1
Abstract:
A variable valve device whose valve opening characteristics are mechanically changed by a simple construction. Rotational motion of a cam shaft (120) is inputted in a valve (104) via a rock member (150). A slide surface (156) is formed on the rock member (150). Intermediate members (170, 172) are arranged so as to be in contact with both the slide surface (156) and a drive cam surface (124). A support member (166) for supporting the intermediate members (170, 172) is attached to a control member (160). The control member (160) is rotatable relative to the camshaft (120) and is interlocked with a control shaft (132) through rotation interlock mechanisms (134, 162). When the control member (160) is rotated in conjunction with the rotation of the control shaft (132), the intermediate members (170, 172) move along the drive cam surface (124) and the slide surface (156). Opening characteristics of the valve varies in conjunction with positional variations of the intermediate members (170, 172).
