Abstract:
1. A variable valve lift apparatus comprising: a high cam and a low cam fixed side by side so as to be eccentric to a camshaft; an outer body pressed by the rotation of the high cam, and has a crossbar formed at the bottom of a front end; an inner body, of which a lower front end protrudes further than the outer body, the lower front end includes a valve member, an upper rear end is pivotally connected to a lost motion hinge shaft coaxially with a rear end of the outer body, and the lower rear end is pivotally connected to a hinge member; and a latching portion inserted into the inner body and selectively connected to the crossbar of the outer body to make movement of the inner body dependent on the movement of the front end of the outer body; wherein the lost motion hinge shaft is disposed in the same direction as a hinge point between the inner body and the hinge member with respect to the camshaft; and wherein the latching portion is positioned midway between the hinge member connected to the lower rear end of the inner body and the valve member.
