Abstract
An SOHC-type valve operating system in an internal combustion engine having a single cam shaft commonly provided for a pair of intake valves and a pair of exhaust valves. A plurality of intake valve driving members are rockably disposed between the cam shaft and the pair of intake valves and have an operative-connection switchover mechanism for switching over the connection and disconnection of the intake valve driving members. A pair of exhaust valve driving members are rockably disposed between the cam shaft and the pair of exhaust valves and independently operate each of the exhaust valves. The operative-connection switchover mechanism includes a switchover pin movable between a position for operatively connecting adjacent intake valve driving members and a position for releasing such connection, which pin is slidably mounted in a cylindrical sleeve secured to the intake valve driving members for guiding the movement of the switchover pin. The cylindrical sleeve also rotatably supports a cylindrical rotor in rolling contact with a cam provided on the cam shaft. The operative-connection switchover mechanism is disposed on the opposite side of the intake valves with respect to the rocking axis of the intake valve driving member whereby space for disposing a component such as an ignition plug is available on the intake side of the engine.
