Abstract: A valve opening and closing apparatus includes a rocker arm which is in contact with a cam and causes a valve to be opened and closed using rotation of the cam. In particular, the valve opening and closing apparatus includes an eccentricity-creating unit which is disposed on the rocker arm and changes an eccentric position using rotation. A contact-maintaining unit of the valve opening and closing apparatus is disposed between the rocker arm and the eccentricity-creating unit so as to maintain the contact between the cam and the rocker arm when the cam is rotating.

Abstract: A variable valve lift apparatus includes a rocker arm having a rocker arm shaft penetrating therethrough. One portion of the rocker arm is supported by a cam shaft and another portion thereof contacts an upper end of an intake valve or an exhaust valve to open and close the intake valve or the exhaust valve. An actuator is disposed at an end of the rocker arm and protrudes toward the intake valve or the exhaust valve depending on an oil pressure applied to change an opening of the intake valve or the exhaust valve. A control valve applies the oil pressure to the actuator to maintain an opened state of the intake valve or the exhaust valve when the intake valve or the exhaust valve is closed.
