可变气门升程装置
摘要：
本发明公开了一种可变气门升程装置，其用于在至少两级中改变进气门或排气门的升程，所述可变气门升程装置可包括杆本体、活塞、圆筒、液压室、活动部分、铰链部分、辊、旋转轴、导向槽、液压供应部分和弹性构件，其中所述杆本体可在具有连接至其的进气门或排气门的端部处进行杆运动；所述活塞可在所述圆筒中进行往复运动；所述旋转轴可穿过所述铰链部分和所述辊，并作为所述辊的旋转中心且与所述辊一起移动；所述液压供应部分可将液压提供至所述液压室以用于移动所述活塞；如果去除提供至所述液压室的液压，则所述弹性构件可使所述活塞返回。
摘要（英）：

A variable valve lift apparatus for changing a lift of an intake or exhaust valve in at least two stages may include a lever body, a piston, a cylinder, a hydraulic pressure chamber, an active portion, a hinge portion, a roller, a rotation shaft, a guide slot, a hydraulic pressure supply portion, and an elastic member, in which the lever body may make a lever motion at an end with the intake valve or the exhaust valve connected thereto, the piston may make reciprocal motion in the cylinder, the rotation shaft may pass through the hinge portion and the roller and be a rotation center of the roller, moving together with the roller, the hydraulic pressure supply portion may supply hydraulic pressure to the hydraulic pressure chamber for moving the piston, and the elastic member may return the piston if the hydraulic pressure being supplied to the hydraulic pressure chamber is removed.
