Abstract: A variable valve operating system is provided to improve functions of a variable valve by constructing a valve device to have a mechanical structure instead of a hydraulic structure. A variable valve operating system comprises a cam follower(50) and a valve device. The cam follower includes an inner body(65) and an outer body. A locking member(60) is formed at one end of the inner body. The outer body surrounds a lateral portion of the inner body and is latched with the inner body by a latching device(70). If the inner body is latched with the outer body by the latching device, the inner and outer bodies perform the see-saw movement about a driving cam, thereby lifting an intake/exhaust valve(95) connected to the driving cam by a lost motion pin(90).

A continuously variable valve lift system in an engine includes a cam shaft(12), a rotary adjustment mechanism(14), a bearing member(18), a resilient member(20), and a rocker arm(22). The cam shaft is installed at a cylinder head to be linked to a crankshaft, and has a plurality of cams for opening/closing suction/discharge valves. The rotary adjustment mechanism has a first contact part variably adjusted according to an operation state of the engine and having a predetermined radius of curvature. The bearing member is pressed by the cam and the first contact part of the rotary adjustment mechanism to vary a moving trajectory in a dependent manner. The resilient member resiliently adheres the bearing member, the cam, and the rotary adjustment mechanism to each other. The rocker arm is installed to press the suction/discharge valves.
