Valve driving apparatus of internal combustion engine

摘要

In the valve driving apparatus (21) of an internal combustion engine, a plurality of electromagnetic actuators (23) for driving a valve element (17) functioning as an intake valve or an exhaust valve is mounted to an actuator body (22). Moreover, a bus bar (41, 42) is mounted to the actuator body (22) as wiring for supplying electric power to each of the electromagnetic actuators (23). The actuator body (22) has a flow path (38) for allowing a cooling medium (39) to flow therethrough. The bus bar (41, 42) is provided near the flow path (38) of the actuator body (22). This structure enables a reduction in space for power distribution while minimizing overheating of the wires. <IMAGE>
